28
Q

Three different processes that occur to tubular fluid in nephron before considered urine

A

Filtration

Tubular reabsorption

Tubular secretion

29
Q

Filtration

A

Glomerulus is compressed of fenestrated capillaries

30
Q

Tubular reabsorption

A

While the fluid is in the tubular system, any filtrate needed by the body is reabsorbed

31
Q

Tubular secretion

A

Substances that the body doesn’t need get secreted from capillaries

32
Q

Renal corpuscle is made of two structures

A

Glomerulus
Thick tangle of fenestrated capillaries

Glomerular capsule
Epithelial capsule surrounding glomerulus

33
Q

Where do the afferent arterioles enter and become the glomerulus in the renal corpuscle

Efferent arterioles exit

A

Vascular pole

34
Q

Visceral layer

A

Made up of podocytes

Each podocyte has pedicles

37
Q

Patiently layer

A

Made up of simple squamous epithelium, lines inside of capsule

38
Q

Where does proximal convoluted tube begin

A

Tubular pole of the glomerulus

39
Q
