In anatomy of the digestive system, the colon or large intestine is the part of the intestine from the cecum to the rectum. Its primary purpose is to extract water from feces. In mammals, it consists of the ascending colon on the right side, the transverse colon, the descending colon on the left side, the sigmoid colon, and the rectum.

Peristalsis is a method or a occurence that happens when the food goes down the digestive tract. the frequent  relaxation and contraction of the muscles in the digestive tract allow the food to go from the mouth to your stomach\n\nChyme is the food that is partially digested and it is transferred from stomach to the duodenum (the entrance of small intestine)\n\nVilli is something hair-like structure that is present in your small intestine. The major function of villi is to absorb nutrients\n\nIt ususally takes an two and half to six hours for food to be done in the digestive system.\n\nThe function of the large intestine is to absorb water, vitamin and electrolytes\n\nYou mean the digestive tract? about 9 meters.. or 30 feet

The circulatory system comprises all structures that relate to the circulation of blood throughout the body.  This includes the heart, the aorta (main artery coming out of the heart), the major organ arteries, the smaller branch arteries going into the organs, arterioles (even smaller branch arteries), capillaries (fine, almost microscopic vessels where oxygen and nutrients are delivered to the organ), venules (small veins that start the return of blood away from the organ), small veins, larger veins, inferior vean cava (main vein from the lower 2/3 of the body), superior vena cava (main vein from the upper 1/3 of the body), and finally the heart again.  The circulatory system is essentially a closed plumbing system, driven by the beating of the heart.

As blood is sent through the capillaries, some of it is filtered through the epithelial wall into the interstitial spaces around the cells in tissues.  This fluid is slowly forced into small little vessels called lymph vessels.  Lymph is the best way of finding out if there are bacteria, virus (pathogens) or even allergens/antigens in the tissues.  The lymph eventually drains into lymph nodes which are major sites for immune system communication. As fluid enters, some is pushed out.  These lymph vessels continue to merge until they become a major lymph vessel that drains in the subclavian vein.  This merges with the vena cava and thus returned to blood circulation.

The gastrointestinal tract or digestive tract, also referred to as the GI tract or the alimentary canal or the gut, is the system of organs within multicellular animals which takes in food, digests it to extract energy and nutrients, and expels the remaining waste.\n\nThe GI tract differs substantially from animal to animal. For instance, some animals have multi-chambered stomachs.

The lymphatic vessels resemble veins in that they transport body fluids. The lymphatic vessels contain valves similar to those found in the major veins of the body.

The Circulation of Blood\n\nThe human circulatory system is really a two-part system whose purpose is to bring oxygen-bearing blood to all the tissues of the body. When the heart contracts it pushes the blood out into two major loops or cycles. In the systemic loop, the blood circulates into the body’s systems, bringing oxygen to all its organs, structures and tissues and collecting carbon dioxide waste. In the pulmonary loop, the blood circulates to and from the lungs, to release the carbon dioxide and pick up new oxygen. The systemic cycle is controlled by the left side of the heart, the pulmonary cycle by the right side of the heart. Let’s look at what happens during each cycle:\n\nThe systemic loop begins when the oxygen-rich blood coming from the lungs enters the upper left chamber of the heart, the left atrium. As the chamber fills, it presses open the mitral valve and the blood flows down into the left ventricle. When the ventricles contract during a heartbeat, the blood on the left side is forced into the aorta. This largest artery of the body is an inch wide. The blood leaving the aorta brings oxygen to all the body’s cells through the network of ever smaller arteries and capillaries. The used blood from the body returns to the heart through the network of veins. All of the blood from the body is eventually collected into the two largest veins: the superior vena cava, which receives blood from the upper body, and the inferior vena cava, which receives blood from the lower body region. Both venae cavae empty the blood into the right atrium of the heart.\n\nFrom here the blood begins its journey through the pulmonary cycle. From the right atrium the blood descends into the right ventricle through the tricuspid valve. When the ventricle contracts, the blood is pushed into the pulmonary artery that branches into two main parts: one going to the left lung, one to the right lung. The fresh, oxygen-rich blood returns to the left atrium of the heart through the pulmonary veins.\n\nAlthough the circulatory system is made up of two cycles, both happen at the same time. The contraction of the heart muscle starts in the two atria, which push the blood into the ventricles. Then the walls of the ventricles squeeze together and force the blood out into the arteries: the aorta to the body and the pulmonary artery to the lungs. Afterwards, the heart muscle relaxes, allowing blood to flow in from the veins and fill the atria again. In healthy people the normal (resting) heart rate is about 72 beats per minute, but it can go much higher during strenuous exercise. Scientists have estimated that it takes about 30 seconds for a given portion of the blood to complete the entire cycle: from lungs to heart to body, back to the heart and out to the lungs.\n\n^_^

I agree, this is your homework, and you need to do it.  But let me say something, so you don't pick up a mistake here.  The thin skin that holds the organs in place is not fat bodies.  It is something that is related to the embryonic development of the animal.  As the embryo develops you get three germ layers, one of which gives rise to the skin you are looking for.  As for the intestine question, ask yourself what the function of the differnt parts of the digestive tract is.  In fact, think about what it is you need to achieve in digestion.  \n\nGood luck.

who cares?! bottom line is it's good for you!\n\nif you really want to know:\n\nnervous system, cardiovascular systen, muscle system,immune system, respiratory system, digestive system, exocrine and endocrine system....pretty much anything except for the reproductive system depending on what you're doing in the water ;)

In humans, digestion begins in the mouth where food is chewed (mastication) with the teeth. The process stimulates exocrine glands in the mouth to release digestive enzymes such as salivary amylase, which aid in the breakdown of food, particularly carbohydrates. Chewing (mechanical) also causes the release of saliva, which helps condense food into a bolus that can be easily passed through the oesophagus. The oesophagus is about 20 centimeters long. The food is pushed down by a movement called peristalsis, which is the wave-like contraction of smooth muscle tissue, characteristic of the digestive system.\n\nThe food enters the stomach upon passage through the cardiac sphincter. In the stomach, food is churned and thoroughly mixed with a digestive fluid, composed chiefly of hydrochloric acid, and other digestive enzymes to further decompose it chemically for a few hours. As the acidic level changes in the stomach and later parts of the digestive tract, more enzymes are activated or deactivated to extract and process various nutrients.\n\nAfter being processed in the stomach, food is passed to the small intestine via peristalsis. This is where most of the digestive process occurs. It passes through the pyloric sphincter and enters the first 10 inches of the small intestine, the duodenum, where it is further mixed with 3 different liquids, which are bile (which helps aid in fat digestion, otherwise known as emulsification), pancreatic juice (made by the pancreas), and intestinal juice. They also add several enzymes: maltase, lactase and sucrase, to process sugars. Trypsin and chymotrypsin are other enzymes added in the small intestine. (Bile also contains pigments that are by-products of red blood cell destruction in the liver; these bile pigments are eliminated from the body with the feces.) Most nutrient absorption takes place in the small intestine. The nutrients pass through the small intestine's wall, containing small, finger-like structures called villi. The blood, which has absorbed nutrients, is carried away from the small intestine via the hepatic portal vein and goes to the liver for filtering, removal of toxins, and nutrient processing.\n\nAfter going through the small intestine, the food then goes to the large intestine. The large intestine has 3 parts: the cecum (or pouch that forms the T-junction with the small intestine), the colon, and the rectum. In the large intestine, water is reabsorbed, and the foods that cannot go thorugh the villi such as fiber, can be stored in large intestine. Fiber helps to keep the food moving through the G.I. tract. The food that cannot be broken down is called feces. Feces is stored in the rectum until it is expelled through the anus.

Are you a young woman or a student? YES or NO answer only please! I appreciate you asking and your eagerness. \n\nSorry, but your question does not lend itself to a yes or no answer. the lymphatic system is part of the immune system but not the entire immune system.  And there is no such thing as "the Immunity System." Immune system, yes. But no Immunity System.

The Respiratory system has its central processing functions in the lungs.  The lungs compose of thousands of little "sacks" which expand and contract to breath in and out.  In the lungs oxygen is transferred to the red blood cells which contain haemoglobin.  The haemoglobin is very good at storing/transporting oxygen.  This travels around the circulatory system, and the oxygen rich red blood cells visit cappillaries all throughout the body in order to keep the body functions alive.  The deteriorating effects of Oxygen, however, are what cause us to age.  Oxygen is in fact our source of life, and the reason we eventually die.\n\nThe digestive system is the source for all of our growth.  In order to become larger, we must ingest complex chemical compounds and convert these into proteins.  Energy gained from digestion allows us to function internally as well as externally.  Our digestive system allows the heart to pump and function the circulatory system.  The circulatory system is supplied by both the digestive and respiratory systems and transports Oxygen/proteins/white blood cells, etc. around the body.  \n\nSo these three systems are related in that simple way, but there are many other ways to relate the work the digestive and circulatory system do that affect the respiratory system.

To circulate the blood.\n\nOf course, blood circulation is so important because it carries oxygen and nutrients to tissues, and carries wastr products, especially Carbon Dioxide, away from the tissues.

Lymph nodes are any of numerous oval bodies, distributed throughout the lymphatic system, that produce and house lymphocytes (white blood cells formed in lymphatic tissue) and filter microorganisms and other particles from lymph. \nThey are a defense mechanism of the body against infection and disease.
