- urine contains water, urea and salts
- salt , water and urea amount vary with how well a person is operating

2.74 - ADH
- ADH - anti- divretic hormone
- it is produced in the brain in the hypothadumus
- ADH goes through the blood from the brain and its target is the kidney
- the effect is to control and alter the quanity of the deposition of water in the blood
- this makes the blood more or less concentrated
- ADH targets the collecting duct
- this allows more water to come out of the collecting duct
- this makes the collecting duct more porous
- the urine would be more concentrated and the volume decreases

2.73 - glucose re-absoption
- glucose goes from the glomerula filtrate to the blood
- urine does not contain glucose
- in the proximal convaluted tubule glucose is removed and is taken back to the blood
- urine does not contain glucose
- in the proximal convaluted tubule glucose is removed and is taken back to the blood
2.72 - water re-absorption
- when the filtration occurs in the bowman's capsule, it will filter out too much water
- when it reaches the collecting duct, water is removed form the collecting duct
- the water is then returned to the blood
- this is selected re-absoption of water
- when it reaches the collecting duct, water is removed form the collecting duct
- the water is then returned to the blood
- this is selected re-absoption of water
2.71 - ultrafiltration
- the filtration begins at the bowmans capsule
- blood comes in with high pressure, goes through the glomerulus
- the blood comes out of a narrow blood vessel - this gives the blood even higher pressure
- the high pressure forces the plasma out of the blood vessel and into the bowmans capsule
- this causes glomerula filtrate which contains water, salts, amino acids, glucose and urea

2.70 - nephran structure
- nephra - the part in the kidney which does the filtration and composition of the blood
- outer layer of the nephra is called the cortex, the next layer is the medalla and the space is called the pelvic which is where the urine collects
- the kidney is made up of millions of tubular structures (nephra)
- the dead end of the nephra is known as the bowman's capsule
- the twisted sections are the convoluted tubules and the straight parts as the the collecting duct
- the loop is known as the loop of henle
- the first twisted section is called the proximal and the second part is the distal
