Body hair , or androgenic hair , is the terminal hair that develops on the human body during and after puberty. It is differentiated from the head hair and less visible vellus hair , which is much finer and lighter in color. The growth of androgenic hair is related to the level of androgens often referred to as male hormones and the density of androgen receptors in the dermal papillae. Both must reach a threshold for the proliferation of hair follicle cells. From childhood onward, regardless of sex , vellus hair covers almost the entire area of the human body.

In humans , the anus from Latin anus meaning "ring", "circle"   is the external opening of the rectum. Two sphincters control the exit of feces from the body during an act of defecation , which is the primary function of the anus. These are the internal anal sphincter and the external anal sphincter , which are circular muscles that normally maintain constriction of the orifice and which relaxes as required by normal physiological functioning. The inner sphincter is involuntary and the outer is voluntary. It is located behind the perineum which is located behind the vagina or scrotum.
Human bodies are remarkable machines but they can also look, sound and smell funny.

All of this may be the reason why about 40 percent of women are unhappy with their bodies [source: Dreisbach ].
