5 facts about the reproductive system
svp [43]
<span>After you ovulate, your egg is fertile for between 24 to 48 hours and a man’s sperm can survive in the female body for 48 hours. There have actually even been documented cases of live sperm surviving in the female reproductive system for eight days after intercourse!One breast is always larger than the other. Most of the time, it goes without notice but it is typical for breast size to be slightly mismatched. Some women can be born with two uteruses or two vaginas and have no idea until they notice abnormal menstruation or excessive bleeding. You are born with all the eggs you will ever have in a lifetime which can be anywhere from thousands to millions however, only about 300 to 400 of these eggs will mature and be released for fertilization. <span>You ovaries take turns each month releasing eggs.</span></span>

How does a hormone like ADH only know to have an effect on the cells of the kidney and nowhere else?
3241004551 [841]

Answer:

Vasopressin or antidiuretic hormone (ADH) or arginine vasopressin (AVP) is a nonapeptide synthesized in the hypothalamus. Science has known it to play essential roles in the control of the body’s osmotic balance, blood pressure regulation, sodium homeostasis, and kidney functioning. Given its vital role in multiple functions, it is no surprise that ADH is of great clinical significance. ADH primarily affects the ability of the kidney to reabsorb water; when present, ADH induces expression of water transport proteins in the late distal tubule and collecting duct to increase water reabsorption. Several disease states arise when the body loses control of ADH secretion or responds to its presence.
