Parts of the nephron!

Question 1

Glomerulus

and what substances are transported

Answer 1

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

Question 2

Bowman’s capsule

Answer 2

contains fluid pressure in capillaries which aids filtration

Question 3

proximal tubule

Ph is controlled by

what does it transport

Answer 3

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)

Question 4

descending limb of loop of Henle

what does it transport

Answer 4

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

Question 5

Ascending loop of Henle

Answer 5

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

Question 6

distal tubule

what is PH controlled by

what are some of the things it transports

Answer 6

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

Question 7

proximal tubule

Answer 7

in proximal tubule Ph is controlled by tubular secretion of H ions and reabsorption of bicarbonate ions

Question 8

Collecting duct

Answer 8

urine formation

Water (H20), Salt (NaCl), Urea, uric acid, minerals
