What is the function of the uterers?

Why have I not started puberty by 14?
As you may know, The menstrual cycle is simply the lining of your uterers coming out. (forgive me if i spelled anything wrong). Whether you know it or not, you have probly been going through puberty for the past 6 months to year. your breasts will start to get bigger, you may grow a little taller. you may thin out if you were chunkier before. going through puberty is completely natural and is a process which has to happen. it is simply you sex organs being able to function to create a baby. it may seem freaky, but don't worry. its totally and completely normal. it is a normal as sleeping or breathing. go to your mother or sister about it. if you don't have a mother or sister, then go to your dad, teacher, or school nurse.
Describe the two stages of urine formation?
As Kidneys are the Purifying organs in Humans, it receieves blood from the Renal Vein and purifies the blood, the waste material in blood and water is filtered in the kidneys and that's how it produces Urine. The process of urine production is complex. The kidneys are composed of units, Nephrons. Each kidney has about 1 million nephrons. Blood is filtered at the begginning of the nephron, and urine leaves the other end of a nephron in a collecting duct. Collecting ducts drain into Calxyes, renal pelvis, into the ureter (tube from the kidney) and finally into the bladder, where urine is stored until it is excreted, an adult male bladder can hold upto 7L of urine. Everything in blood smaller than a protein molecule is absorded (e.g. glucose, Na+, Ca2+, other minerals and vitamins), during infection of the kidneys or severe illness protein may leak into the nephron and will be excreted into the urine as it cannot be reabsorbed into the blood. Much of what is absorbed from the blood is returned from the nephron to the blood stream (it is reabsorbed). The design of the nephron allows blood volume, Na+ concentration, K+ concentration, pH and other factors to be controlled.
