what are the organs associated with the male reproductive system?

Male reproductive organs or male reproductive system \n\nThe main reproductive organs of the male body are the testes, which produce sperm and also male hormones, in the form of testosterone. The male reproductive system also includes the external genitals — the penis and the scrotum — and the internal structures, including the prostate gland, the vas deferentia (plural for the 2 vas deferens), the urethra, and the seminal vesicles.\n\nTestes\nThe paired oval testes, also known as the male gonads, hang in the scrotal sac. Usually the right testis hangs higher than the left one by about 1 cm. The testes hang outside the body because the temperature inside the body is too high to produce sperm, so they are produced in the testes at about 3 °C lower than body temperature.\n\nEpididymis\nAt the back of the olive-shaped body of each testis is a cap formed by the many coils of a 20-foot long tube called the epididymis. The function of the epididymis is to collect the immature sperm from the testis.\n\nAs the sperm make their long journey through the epididymis they become mature sperm. This journey takes about 20 days and during its course the sperm become fertile and they also become able to move in a swimming motion (doctors refer to the sperm then as ‘motile’).\n\nVas deferens\nJoined to the epididymis is the vas deferens — a thick walled tube which transports sperm from the epididymis up to the prostate gland. The section of the vas deferens that is above the testis can be felt through the loose part of the scrotum. When a vasectomy is performed, it is this part of the vas deferens that is snipped.\n\nThe vas deferens empties into the ejaculatory duct, which passes through the prostate gland to merge with the urethra.\n\nThe urethra\nThe urethra serves as the tube down which urine passes from the bladder through the penis to the outside and also the tube down which semen is ejaculated.\n\nThe prostate\nThe prostate is a walnut-shaped gland that surrounds the urethra. Along with the seminal vesicles it produces the fluid secretions that support and nourish the sperm. Without this fluid to dilute them the sperm cannot move easily.\n\nAfter the age of 40 the prostate enlarges and can press on the urethra. An enlarged prostate is often the cause of urinary problems in older men.

Probably. The testicles are just another example of redundant anatomy in the human body, like the kidneys. A spare is always a good thing to have. As long as that one testicle is functioning properly, it can still produce and still transfer sperm to the seminal vesicles.

lactic acid doesn't have any relation to reproductive system.it accumulates in the body(in muscles)after long phisical exercising.i supose u could be paralised or at list poisoned after injection

Seminiferous tubules make sperm. Semen is a combination of sperm and other fluids created in the process of ejacualtion to protect and nurture the sperm(for the journey).

There are two organ systems that work in conjunction with each other to provide tissues with oxygen and remove carbon dioxide.  Those are the respiratory and the circulatory system (the major organs of these systems being the lungs and the heart respectively).\n\nNutrients are provided by the combined actions of the digestive and circulatory system, and wastes are removed through the combined actions of the circulatory and excretory systems.

There are many, you could try investigating different systems separately:\n- skeleton: detachment of pectoral girdle from skull, attachment of pelvic girdle to column; vertebrae with zygapophyses, limbs with digits, etc.\n- tegument: keratinization, impermeabilization, glands; thermal and hydric regulation.\n- sensory: eye pigments, middle ear with tympanum, loss of lateral line system.\n- other systems: lungs, kidney structure, large intestin, double circulation, etc.

Muscular System\n\nMuscle tissue can be organized into separate muscles that are considered individual organs. Together, they form the muscular system.The cells in a muscle have two major duties: movement and heat production. Although the joints of the skeletal system allow movement, they cannot make the movement themselves. For this they require the contraction of striated muscle. Movement inside the body cavity is provided by muscles made up of smooth muscle cells. For example, the movement of food through the digestive tract is provided by the smooth muscles in the esophagus, stomach, and intestines. Urine is moved through the urinary system by smooth muscles in the ureters, bladder, and urethra. Air is moved in and out of the lungs by smooth muscle in the diaphragm. The muscular system also serves as the major heat generator for the body, keeping tissues warm.\n\nMuscle is made almost entirely of protein. When protein intake through food is low or when food protein is not digested or absorbed properly, it must come from some other source. That source is the muscle tissue. Even when enough protein is provided by the diet, cancer cells will raid the muscles for protein to change into glucose. When muscle tissue decreases, the individual muscle is less able to perform its job, causing weakness in movement and the sensation of coldness due to loss of heat production. Although cancer of the muscular system is very rare, cancer in general can cause a serious loss of muscle tissue.\n\nEndocrine System\nThe endocrine system includes the pituitary and pineal glands; the hypothalamus, thyroid, and adrenal glands; the pancreas; and the testes or ovaries and placenta. These glands release their hormones into the bloodstream directly, as opposed to the exocrine glands, which release their products into ducts. The cell citizens of an endocrine gland are writers. They compose messages called hormones, which are distributed primarily through the bloodstream. Glands perform the same job as the nervous system: communication, integration, and control of bodily functions. The signals travel slower but are much longer lasting. Hormones are the main regulators of metabolism, growth and development, and reproduction.\n\nEndocrine cell tumors are called carcinoids. Cancers of the endocrine system include the following:\n\nGerm cell cancers—These include testicular cancer (male), gestational trophoblasic neoplasms (placental), and ovarian cancer (female). Pancreatic cancer—Over 90 percent of the carcinomas of the pancreas are mucinous adenocarcinomas that originate in the pancreatic duct. Thyroid cancer. Because they stimulate abnormal hormone production, cancers of the endocrine system are often able to produce symptoms in distant sites.\n\nHope this helps, good luck.
