Kidney Anatomy And Histology 1

Question 1

Function of the renal capsule?

Answer 1

Made of connective tissue, As a physical barrier; protection against trauma and maintains the shape of the kidney

Question 2

Function of adipose capsule?

Answer 2

Made of connective tissue; acts as padding, physical protection and maintains the position of the kidneys

Question 3

What is the function of renal fascia?

Answer 3

A connective tissue that anchors the kidneys to surrounding structures

Question 4

What is the glomerulus?

Answer 4

An endothelium that’s a specialised network/knot of capillaries, with an input from afferent arterioles and an output of efferent arterioles

Question 5

What is the glomerular (bowman’s) capsule?

Answer 5

An epithelium (not cardiovascular) that performs the first step in blood filtration, with podocytes (modified epithelium) on the visceral side, and simple squamous epithelium forming the outer wall of the capsule on the parietal side

Question 6

What does the fenestrated endothelium block?

Answer 6

Cells

Question 7

What does the basal lamina block?

Answer 7

Cells and large proteins

Question 8

What does the slit membrane block?

Answer 8

Cells, large proteins and medium proteins

Question 9

How does oxygenated blood circulate the medulla?

Answer 9

Descending vasa recta (from efferent arterioles)

Question 10

How does deoxygenated blood leave the medulla (from peritubular capillaries of the medulla)?

Answer 10

Ascending vasa recta

Question 11

What delivers blood to the glomerulus capillaries/cortex?

Answer 11

Afferent arterioles (from interlobular arteries)
