The Urinary Organs
WHAT IS URINE?
Urine is 95 per cent water and 5 per cent uric acid, urea, salt
s (such as sodium, potassium and chloride) and creatinine. The nephron is part of the filtration unit through which the blood passes in the kidneys. Through this filtration system useful substances are reabsorbed into the bloodstream, and waste substances become urine, which is eventually passed from the kidneys by the ureter.
The urinary system is a sophisticated filtration unit which maintains fluid and chemical balance within the body. Many chemical reactions occurring in cells all over the body produce unwanted by-products and the kidneys filter these from the blood and excrete them in the form of urine.
Male Reproductive System
The testes are located in the scrotum, which hangs outside the body where the temperature is more suitable for efficient sperm production. The testes are responsible for the production of sperm and the release of the male hormone testosterone. Testosterone controls the development of male secondary sexual characteristics at puberty, such as deepening of the voice, facial hair, changes in the penis and testicles and the production of sperm.
After boy reaches puberty, his testes create sperm at a rate of approximately 125 million sperm a day. These gather in the testes and then move on to the coiled tubular system known as the epidemiologist, where they mature. The epidemiologist drains first into the vas deference and from there into the ejaculatory ducts. During sexual activity, these ducts contract and push sperm through the urethra during the process of ejaculation. Read the rest of this entry »
Female Reproductive System
The female reproductive organs are situated in the pelvic cavity and SO are enclosed and protected by the pelvic bones. The ovaries are central to the female reproductive system because they hold all the female ova (eggs). The ovaries release one egg during the process of ovulation, and th
is happens first at puberty. Once released, the egg passes along the Fallopian tube to the uterus (womb) a hollow, muscular organ capable of considerable expansion to accommodate a growing fetus during pregnancy. The neck of the uterus is also known as the cervix, projects into the vagina. The vagina is a muscular organ that is able to expand greatly during sexual intercourse and childbirth.
