16
Q

Renal Medulla

A

Inner part of the kidney the converts filtrate into urine

17
Q

Renal pyramids

A

Cone shaped within the medulla. Converts the filtrate to urine

18
Q

Renal column

A

Located between the cones. They hold up the kidney and provide support to the cortex

19
Q

Renal Pelvis

A

Funnel shaped the collects the urine from the collecting ducts and carries it to the ureters.

20
Q

Renal Corpuscle

A

Aids in converting blood to filtrate. Composed of glomerulus and the glomerular capsule

21
Q

Renal Tubule

A

Converts filtrate into urine. Composed of the proximal convoluted tubule, loop of Henle, and distal convoluted tubule

22
Q

Adrenal Cortex

A

Secretes steroid hormones such as aldosterone and cortisone

23
Q

Adrenal Medulla

A

Secretes epinephrine and norepinphrine

24
Q

Glomerular Filtration rate

A

Filtrate produced per minute by both kidneys

25
Q

ADH (Antidiuretic Hormone)

A

Excreted by the posterior pituitary, Increases water retention. Makes you not pee

26
Q

Aldosterone

A

Steroid hormone secreted by the adrenal cortex increase sodium retention. Increase the amount of sodium that is kept by the body

27
Q

Renin

A

Enzyme that is secreted by the kidney. Converts angiotensinogen into angiotensin I. This increases the amount of aldosterone that is released

28
Q

Natriuetic hormone

A

Secreted by heart atria and decreases sodium retention.

29
Q

Erythropoietin

A

Protein hormone that is secreted by the kidney. Stimulate RBC production in bone marrow
