adrenal,The adrenals are two endocrine glands that sit on the top of the kidneys. The outer part of the adrenals, called the cortex, releases hormones that promote carbohydrate metabolism and reduce muscle fatigue, and affects sexual functions. The inner part of the gland, called the medulla, secretes epinephrine that increases heart rate but constricts blood vessels.

endocrine system,The endocrine system is a group of gland organs that secrete hormones into the bloodstream in order to modify the function of certain target organs. The release of hormones is regulated by other hormones, nerve impulses, impulses from the target organs, and sometimes by hormones released by the gland itself. The endocrine system consists of the hypothalamus, pituitary, pineal, thyroid, parathyroids, thymus, adrenals, pancreas, ovaries, and testes.
epididymis,The epididymis is one of two long, coiled tubes that carry sperm from the testes to the vas deferens.

kidney,The kidneys are two organs that filter blood delivered by the renal vessels via millions of filtering units called nephrons. Liquid waste is filtered out and transmitted to the ureters.

lower endocrine system,The endocrine system is a group of gland organs that secrete hormones into the bloodstream in order to modify the function of certain target organs. The release of hormones is regulated by other hormones, nerve impulses, impulses from the target organs, and sometimes by hormones released by the gland itself. The endocrine system consists of the hypothalamus, pituitary, pineal, thyroid, parathyroids, thymus, adrenals, pancreas, ovaries, and testes.
male genitourinary system,The genitourinary system is the system that combines the reproductive, sexual, and urinary systems and organs of the body. It is also called the urogenital system.
male reproductive system,The male reproductive system consists of the penis, seminal vesicles, prostate, and testis. These organs are involved in production and transmission of sperm containing semen for fertilization of the female egg in reproduction.
nephrons,The nephrons are the filtering units of the kidneys. They resemble a funnel with a long stem and two twisted tubes. There are over a million nephrons in each kidney. They are made up of a renal corpuscle that contains a ball of blood vessels called glomerulus. These are surrounded by a Bowman's capsule and several long tubes. Urine is formed by filtering of blood that passes through these corpuscles.
ovaries,The ovary, plurally called the ovaries, is an endocrine gland of the female reproductive system that produces estrogen which promotes female characteristics and regulates menstruation and pregnancy. The ovaries also produce the eggs, called ova, used in reproduction every 28 days.

pancreas,The pancreas is an endocrine gland located behind and under the stomach. The pancreas releases insulin that promotes carbohydrate metabolism, and it releases glucagon that counters the insulin. The pancreas also releases enzymes that aid digestion of fats and proteins.
parathyroid,The parathyroids are four endocrine glands located in the thyroid. The hormones of the parathyroids regulate blood calcium and phosphorus levels, which in turn regulates muscle tone, blood clotting, and cell membrane health.

penis,The penis is an outer organ of the male reproductive system composed of three circular spongy tissues and it has the urethra running through it for urine and semen release.
pineal,The pineal, commonly called the pineal gland, is a small gland protruding from the brain. It is uncertain what function it performs. It may release a hormone called melatonin, which appears to stop the release of a hormone from the pituitary gland called luteinizing hormone.
pituitary,The pituitary, also called the hypophysis, is a small endocrine gland linked with the hypothalamus. It is located at the base of the brain. The pituitary has two lobes. The front lobe, is called the adenohypophysis, and the back lobe is called neurohypophysis. The hormones it secretes control other glands, and affect metabolism, growth, and maturation. It also releases lutenizing hormone which stimulates the release of hormones that stimulate the production of sperm in men and the production of ova (egg cells) in women.
prostate,The prostate is a spherical gland around the neck of the bladder and where the ejaculatory ducts from the seminal vesicles intersect the urethra. The prostate secretes the substance necessary to liquefy the coagulated semen stored in the seminal vesicles.
pyramid,The pyramids are tubules in the kidney that collect urine and lead it to the renal pelvis.
rectum,The rectum, also called the intestinum rectum, is located after the sigmoid colon and leads to the anal canal. It is the end of the intestinal tract and collects the solid waste of the digestive system. This waste is defecated through the anal canal.
renal artery,The renal artery is one of two branches from the abdominal aorta into the kidneys, adrenals, and ureters.
renal cortex,The renal cortex is the soft, grainy, outer layer of the kidney. It contains more that a million tiny tubes that remove wastes from the blood in the form of urine.
renal pelvis,The renal pelvis is a funnel-shaped cavity in the kidney that collects urine before it is discharged to the ureter.
renal vein,The renal vein is a vein that transports blood from the kidney to the inferior vena cava.
renal vessels,The renal vessels are blood vessels that deliver blood to and from the kidneys to be filtered of waste products, like urea.
scrotum,The scrotum is a bag of skin under the penis that holds the testes, epididymis, and vas deferens.
seminal vesicle,The seminal vesicles are tubelike glands that connect to the testes and the urethra and produce the major fluid of semen as well as store the semen.

thymus,The thymus is an endocrine gland located on top of the heart, and it is important for the immune system until puberty ends. The thymus promotes development of lymph node tissue and produces T-lymphosites, the "killer cells" of the immune system.
thyroid,The thyroid is an endocrine gland located at the throat that surrounds the parathyroid glands. The hormones released by the thyroid increase metabolism, body temperature, and growth.
ureter,The ureters are long thin tubes that carry urine filtered out by the kidneys to the bladder.
ureters,The ureters are long thin tubes that carry urine filtered out by the kidneys to the bladder.
urethra,The urethra is a canal that expels urine from the bladder to outside of the body. The urethra is located in the penis in men and the vagina in women.
urinary system,The urinary system consists of the renal vessels, kidneys, ureters, and urethra. The purpose of these organs is to filter out nitrogen waste products from the blood, like urea, made from body processes that break down proteins, and then remove this waste from the body.
uterus,The uterus is a hollow organ that connects to the fallopian tubes and provides a growing area for fertilized eggs and developing embryos during pregnancy.
vagina,The vagina is an orifice of the female reproductive system which provides exit for urine from the urethra and the release of menstrual fluid from the uterus. The vagina also allows the entrance of semen for egg fertilization.
vas deferens,The vas deferens is a tube that passes sperm from the epididymis to the seminal vesicle.
