Q

What is the role of the collecting duct?

A

Collects filtrate

Q

What blood vessels are associated with nephrons?

A

Afferent arteriole

Q

What is the role of the afferent arteriole?

A

Supplies blood to glomerulus

Q

What is the role of the glomerulus?

A

Fluid forced out of blood into Bowman’s capsule

Q

What is the role of the efferent arteriole?

A

Carries blood away from glomerulus

Q

What is the role of capillaries around tubules and loop?

A

Absorb salts
