Renal Physiology

Question 1

Tubular reabsorption

Answer 1

99% of the filtered water and many useful solutes are absorbed by the tubule cells

Question 2

Tubular Secretion

Answer 2

The renal tubule and duct cells secrete waste, drugs and excess ions into the fluid

Question 3

Filtration membrane

Answer 3

A leaky barrier

Question 4

Fenestrations

Answer 4

Pores the small size permits all solute in blood plasma to exit glomerular capillaries but prevents filtration of blood cells and platelets

Question 5

Basal Lamina

Answer 5

A layer of cellular material between the endothelium and podocytes, negative charges in the matrix prevent filtration of large negatively charged plasma protein

Question 6

Pedicel

Answer 6

Extends from podocytes, water goes through the thousands of foot like processes

Question 7

Glomerular Filtration

Answer 7

Water and most solutes in blood plasma move across the wall of glomerular capillaries, then into the glomerular capsule then to the renal tubule
