E2 Urine Formation

Question 1

Roll of the nephron

Answer 1

Filters blood, reabsorbs essentials, secreted excess toxins like urea

Question 2

Steps to urine formation

Answer 2

Glomerular filtration, tubule reabsorption, tubular secretion, water reabsorption

Question 3

What is glomerular filtration

Answer 3

Moves water and small solutes from blood to nephron

Question 4

What is tubule reabsorption

Answer 4

Reabsorbs useful solutes back to blood stream (sodium)

Question 5

What is tubular secretion

Answer 5

Additional wasted move from capillary into nephron

Question 6

What is water reabsorption

Answer 6

Remained water from filtrate and return to blood

Question 7

Capillaries in Glomerulus are extra permeable, true or false?

Answer 7

True

Question 8

What is the fluid in bowman’s capsule known as?

Answer 8

Filtrate

Question 9

Does glomerular filtration require energy

Answer 9

No

Question 10

Proximal tubule function

Answer 10

Reabsorbs nutrients through active transport and secretes hydrogen

Question 11

Function of loop of henle

Answer 11

Reabsorbs water and ions from filtrate
Descending loop = permeable to o2
Ascending = non permeable to o2, permeable to salt

Question 12

Distal tube function

Answer 12

Active transports wastes from blood to nephron, reabsorbs water though osmosis and regulates hormones to maintain homeostasis

Question 13

Collecting duct function

Answer 13

Reabsorbs water to further concentrate filtrate

Question 14

What is urine

Answer 14

Super concentrated filtrate
