Some hormones, like parathyroid hormone and calcitonin, directly act on cells that lay down and take up bone--mainly acting to regulate the calcium, but also the actual amount of bone.\n\nOthers, like testosterone, estrogen and progesterone, act less directly; all three of these, like calcitonin, tend to increase the amount of bone mass laid down.\n\nThere are some other substances involved as well: calcium and phosphate (bone is mostly a calcium hydroxy apatite crystal, which is mainly calcium and phosphate) and Vitamin D, which is involved in the body's handling of calcium.

the endocrine system's main function is to maintain homeostasis. it does so mostly through chemical messengers called hormones. hormones are produced in one organ and used in another. the endocrine system uses many glands such as the pituitary gland, which is like the director of the endocrine system, the hypothalamus, which controls the pituitary gland, and the pineal gland, which controls growth and development and so on and so forth. there are also numerous other glands, like the thyroid gland, the and non-glands, like the pancreas, that secrete (another word for make) hormones, in the case of the pancreas, it secretes insulin and glycogen, which lower and increase the level of sugar in your blood. \n\n\nhope this helps you at all and you had better not copy  this word for word.

In the molecular world of life, hormone is a molecule that 'signals wide-spread effects' while an enzyme 'enables local effects'.\n\nHORMONE IS A MESSENGER: It is a protein or other type (e.g., steroids) of molecule. It is released from one cell in the body, travels in the blood (in animals), reaches some other cell that 'responds'. In this target cell, there are 'specific receptors' that interact with this messenger-molecule and the cell 'responds'. For example, the skin cells in the face of a male teenager respond (grow hair) to several molecules of testosterone, a steroid hormone,  that are produced in testes. The entire process of response requires (a) availability of specific hormone, (b)its specific receptor as well as (c) the downstream series of reactions in the target cell. Different types of hormones cause different responses. \n\nENZYME IS A CATALYST: These molecules also act on very specific molecules (called substrates in this case) to produce an effect. The effects can be breaking a molecule, joining two molecules, modifying part of a molecule etc. In fact, these effects may never happen without an enzyme. However, the enzyme itself is largely unaffected and can be recycled. Mostly, enzymes are proteins and are not secreted through blood.

The thyroid is one of the larger endocrine glands in the body. It is located in the neck and produces hormones, principally thyroxine and triiodothyronine, that regulate the rate of metabolism and affect the growth and rate of function of many other systems in the body.

The endocrine system  regulates mood, growth and development, tissue function, metabolism, and sexual function and reproductive processes.It is in charge of body processes that occur slowly. The most imporant parts of the endocrine system are hormones and glands. Hormones transfer information and instructions from one set of cells to another and only affect certain cells. Glands produce and secrete chemicals. A gland selects and removes materials from the blood, processes them, and secretes the finished chemical product for use somewhere in the body.

estrogen levels drop dramatically. this causes a huge effect on bone density. estrogen encourages the build up of bone, so with out it, bone loss accelerates. so in the first 5 years after menopause, bone loss is very accelerated, then levels off to slow rate of decline (thebody gets used to the new levels).

There are two primary hormones that affect bone metabolism:\ncalcitonin and parathyroid hormone.\n\nCalcitonin is released when blood calcium levels are high and (1) promotes calcium incorporation into bone and (2) blocks the liberation of calcium from bone. You can think of calcitonin as a bone sparer.\n\nParathryoid hormone is released when blood calcium levels are low and tends to liberate calcium from bone.  You can think of parathyroid hormone as a bone degrader.\n\nThere are other hormones that impact bone metabolism, these include thyroid hormone and estrogen.\n\nThe primary nutritive requirements for healthy bone metabolism are dietary calcium, phosphorus and Vitamin D that helps you to absorb the calcium from foods.

The foundations of the endocrine system are the hormones and glands. As the body's chemical messengers, hormones (pronounced: hor-moanz) transfer information and instructions from one set of cells to another. Although many different hormones circulate throughout the bloodstream, each one affects only the cells that are genetically programmed to receive and respond to its message. Hormone levels can be influenced by factors such as stress, infection, and changes in the balance of fluid and minerals in blood.\n\nA gland is a group of cells that produces and secretes, or gives off, chemicals. A gland selects and removes materials from the blood, processes them, and secretes the finished chemical product for use somewhere in the body. Some types of glands release their secretions in specific areas. For instance, exocrine (pronounced: ek-suh-krin) glands, such as the sweat and salivary glands, release secretions in the skin or inside of the mouth. Endocrine glands, on the other hand, release more than 20 major hormones directly into the bloodstream where they can be transported to cells in other parts of the body. \n\nThe major glands that make up the human endocrine system are the hypothalamus, pituitary, thyroid, parathyroids, adrenals, pineal body, and the reproductive glands, which include the ovaries and testes. The pancreas is also part of this hormone-secreting system, even though it is also associated with the digestive system because it also produces and secretes digestive enzymes. Although the endocrine glands are the body's main hormone producers, some non-endocrine organs - such as the brain, heart, lungs, kidneys, liver, thymus, skin, and placenta - also produce and release hormones.\n\nThe hypothalamus (pronounced: hi-po-tha-luh-mus), a collection of specialized cells that is located in the lower central part of the brain, is the primary link between the endocrine and nervous systems. Nerve cells in the hypothalamus control the pituitary gland by producing chemicals that either stimulate or suppress hormone secretions from the pituitary. \n\nAlthough it is no bigger than a pea, the pituitary (pronounced: puh-too-uh-ter-ee) gland, located at the base of the brain just beneath the hypothalamus, is considered the most important part of the endocrine system. It's often called the "master gland" because it makes hormones that control several other endocrine glands. The production and secretion of pituitary hormones can be influenced by factors such as emotions and seasonal changes. To accomplish this, the hypothalamus relays information sensed by the brain (such as environmental temperature, light exposure patterns, and feelings) to the pituitary.\n\nThe tiny pituitary is divided into two parts: the anterior lobe and the posterior lobe. The anterior lobe regulates the activity of the thyroid, adrenals, and reproductive glands. Among the hormones it produces are:\n\ngrowth hormone, which stimulates the growth of bone and other body tissues and plays a role in the body's handling of nutrients and minerals \nprolactin (pronounced: pro-lak-tin), which activates milk production in women who are breastfeeding \nthyrotropin (pronounced: thigh-ruh-tro-pin), which stimulates the thyroid gland to produce thyroid hormones \ncorticotropin (pronounced: kor-tih-ko-tro-pin), which stimulates the adrenal gland to produce certain hormones \nThe pituitary also secretes endorphins (pronounced: en-dor-finz), chemicals that act on the nervous system to reduce sensitivity to pain. In addition, the pituitary secretes hormones that signal the ovaries and testes to make sex hormones. The pituitary gland also controls ovulation and the menstrual cycle in women. \n\nThe posterior lobe of the pituitary releases antidiuretic (pronounced: an-ty-dy-uh-reh-tik) hormone, which helps control body water balance through its effect on the kidneys and urine output; and oxytocin (pronounced: ahk-see-toe-sin), which triggers the contrac

A steroid is a lipid characterized by a carbon skeleton with four fused rings. Different steroids vary in the functional groups attached to these rings. Hundreds of distinct steroids have been identified in plants, animals, and fungi. Their most important role in most living systems is as hormones. Steroid skeleton. Carbons 18 and above can be absent. In human physiology and medicine, the most important steroids are cholesterol, the steroid hormones, and their precursors and metabolites. In conversations, the term steroid is often used more restrictively in specific contexts. For instance, steroid in common medical usage by non-endocrinologists usually refers to corticosteroids, nearly always glucocorticoids. In an athletic or body-building context, steroid commonly refers to anabolic steroids. Cholesterol is an important steroid alcohol, being a common component of animal cell membranes. However, a high level of it can cause various conditions and diseases, such as atherosclerosis. Most other steroids are synthesized from cholesterol. Also, various hormones, including vertebrate sex hormones, are steroids created from cholesterol.

First, the bones are the structural support for muscles, nerves, blood and lymph circulation systems, as well has holding the various organs and glands in place.\n\nMay I recommend a few?

The skeletal system is the base for all of the other systems, in your question, muscles are directly attached to bone by tendons and ligaments.  The nerves then run around and through our muscles so when a thought to move is made then the nerve is sent from the brain to the nerves then they send it to the muscle creating a movement.

Don't really  know what u mean? Like, the lymph system is related to the circulatory system, in that the lymph helps filter pathogens and the circulatoy helps move lymph cells and supplys oxygen to them. Yet, all the systems are related in one fastion or another. I would pick the endocrine system- hormones signals- and link it to any system you like, b/c that really is linked to everything

In general, the endocrine system is in charge of body processes that happen slowly, such as cell growth. Faster processes like breathing and body movement are monitored by the nervous system. But even though the nervous system and endocrine system are separate systems, they often work together to help the body function properly

a mammal’s inner support frame, called a skeleton, is composed of two parts, the axial (including the skull, vertebral column, thoracic basket, and pelvic girdle), and the appendicular (consisting of the bones of the limbs, or appendages). \n\nThe Skeletal System serves many important functions; it provides the shape and form for our bodies in addition to supporting, protecting, allowing bodily movement, producing blood for the body, and storing minerals.\n\nFunctions\n\nIts 206 bones form a rigid framework to which the softer tissues and organs of the body are attached. \n\nVital organs are protected by the skeletal system. The brain is protected by the surrounding skull as the heart and lungs are encased by the sternum and rib cage.\n\nBodily movement is carried out by the interaction of the muscular and skeletal systems. For this reason, they are often grouped together as the musculo-skeletal system. Muscles are connected to bones by tendons. Bones are connected to each other by ligaments. Where bones meet one another is typically called a joint. Muscles which cause movement of a joint are connected to two different bones and contract to pull them together. An example would be the contraction of the biceps and a relaxation of the triceps. This produces a bend at the elbow. The contraction of the triceps and relaxation of the biceps produces the effect of straightening the arm.\n\nBlood cells are produced by the marrow located in some bones. An average of 2.6 million red blood cells are produced each second by the bone marrow to replace those worn out and destroyed by the liver. \n\nBones serve as a storage area for minerals such as calcium and phosphorus. When an excess is present in the blood, buildup will occur within the bones. When the supply of these minerals within the blood is low, it will be withdrawn from the bones to replenish the supply. \n\nDivisions of the Skeleton\n\nThe human skeleton is divided into two distinct parts:\n\nThe axial skeleton consists of bones that form the axis of the body and support and protect the organs of the head, neck, and trunk.\n\nThe Skull \nThe Sternum\nThe Ribs\nThe Vertebral Column \n\nThe appendicular skeleton is composed of bones that anchor the appendages to the axial skeleton.\n\nThe Upper Extremities\nThe Lower Extremities\nThe Shoulder Girdle\nThe Pelvic Girdle--(the sacrum and coccyx are considered part of the vertebral column)
