Question 1

Nephrons

Answer 1

approximately 1 million nephrons located in each kidney.

Question 2

Glomerulus

Answer 2

cluster of capillaries that filter substances from the blood.

Question 3

Bowman´s Capsule

Answer 3

¨c¨ shaped structure, surrounding the glomerulus; sends filtrated materials to the convoluted tubule.

Question 4

Proximal Convoluted Tubule (PCT)

Answer 4

receives fluid from glomerular capsule. reabsorbs 65% of nutrients, sodium, glucose, potassium, and calcium.

Question 5

loop of henle

Answer 5

fluid enters the loop from the PCT. reabsorbs 15%.

Question 6

Distal Convoluted Tubule (DCT)

Answer 6

receives fluid from the loop. reabsorbs 15% mostly only water.

Question 7

collecting Tubule

Answer 7

fluid enters from DCT. Reabsorbs 5%.

Question 8

Renal pelvis (basin)

Answer 8

receives fluid from the collectiong tubule

Question 9

Hillum

Answer 9

a notch, located in each kidney, where ureters, blood, lymph, and nerves enter and leave each kidney.

Question 10

Renal Corpuscle

Answer 10

where filtration occurs inside each nephron; it consists of the Bowman´s Capsule and the Glomerulus.
