Glomerulus and what substances are transported
filtration of water and dissolved solutes occurs as blood is forced through walls of glomerulus Na+ Cl- H2O H+ glucose, amino acids, mineral, urea, uric acid, etc
Bowman’s capsule
contains fluid pressure in capillaries which aids filtration
proximal tubule Ph is controlled by what does it transport
selective reabsorption of nutrients from filtrate back into blood by active and passive transport Ph is controlled by secretion of H+ ions and reabsorption of bicarbonate ions (hCO3-) extra transports HCO3- ,potassium ions AMMONIA, and the usual rest (ex salt or water)
descending limb of loop of Henle what does it transport
The descending limp of loop of Henle is permeable to water, resulting in loss of water from filtrate by osmosis this causes the salt to become concentrated in filtrate as the descending limb penetrates inner medulla Transports only H20
Ascending loop of Henle
it is a thin segment of ascending limb of loop o Henle is permeable to salt, resulting in diffusion of salt out of ascending limb. Salt continues to pass from filtrate to interstitial fluid in thick segment of ascending limb transport NaCl
distal tubule what is PH controlled by what are some of the things it transports
selective reabsorption of nutrients from blood into nephron by activate transport. Distal tubule helps regulate potassium and salt NaCl concentration of body fluids Ph is controlled by secretion of H ions and reabsorption of HCO3- ions HCO3 the usual (uric acid, water etc) ammonia
proximal tubule
in proximal tubule Ph is controlled by tubular secretion of H ions and reabsorption of bicarbonate ions
Collecting duct
urine formation Water (H20), Salt (NaCl), Urea, uric acid, minerals
