16
Q

Basic process of ultrafiltration

A

Removes waste and good products Forces particles into Bowden’s capsule bc of pressure

17
Q

What is the filtrate made up of

A

Glucose amino acids urea Uris acid creatinine salts

18
Q

Two types of reabsorption

A

Passive and active

19
Q

Active reabsorption

A

Glucose and protein and water sol vits go up conc gradient to capillaries

20
Q

Passive reabsorption

A

Water moves down conc grade it back to capillaries

21
Q

What is the function of the loop of henle

A

High concentration of salt for osmotic withdrawal from distal tubules and collecting ducts

22
Q

Selective reabsorption occurs where

A

Proximate convoluted tubule

23
Q

How does the proxy mate convoluted tubule increase its SA

A

Cuboidal epithelial cells with villi and mitochondria
