Where is the Glomerulus?

A

Where is the Bowman’s Capsule?

B

Where is the Afferent Arteriole?

C

Where is the renal artery?

D

Where is the renal vein?

E

Where is the Proximal Convoluted Tubule?

F

Where is the Dscending loop of Henle?

G

Where is the Loop of Henle

H

Where is the Ascending Loop of Henle?

L

Where is the Efferent Arteriole?

I

Where is the Distal Convoluted Tubule?

J

Where is the Collecting Duct?

K

Where does Filtration happen?

Glomerulus & Bowman’s Capsule

Where does Reabsorption happen?

PCT, DCT, Loop, CD

Where does Secretion happen?

DCT, CD

What substances are involved with Filtration?

water, dissolved substances, glucose, amino acids, urea, ion

What substances are involved with Reabsorption?

Water, salt (Na⁺), glucose

What substances are involved with Secretion?

Na⁺, H⁺, K⁺, HCO₃^-, NH₄, toxins, drugs

In this stage, pressure forces water & dissolved substances (glucose, amino acids, urea, ions) from blood into Bowman’s capsule (nephron)

Filtration

Return of substances from filtrate (in nephron) to blood or kidney or interstitial fluid

Reabsorption

• Active transport of materials (Na⁺, H⁺, K⁺, HCO₃^-, NH₄, toxins, drugs) into the nephron tubule

• Electrolyte, pH balance

Secretion
