Q

Target cells/organs of calcitonin?

A

Bones
Kidneys
Intestines

21
Q

Effect of calcitonin?

A

Bones - osteoblasts build up matrix to store CA2+
Kidneys - decrease reabsorbtion of CA2+ from the filtrate
Intestines - decrease absorption of CA2+ from food

22
Q

Target cells/organs of parathyroid hormone?

A

Bones
Kidneys
Intestines

23
Q

Effect of parathyroid hormone?

A

Bones - osteoclasts break down matrix to release CA2+
Kidneys - increases reabsorbtion of CA2+ from filtrate
Intestines - increases absorption of CA2+ from food

24
Q

Target cell/organ of thymosins?

A

T-lymphocytes

25
Q

Effect of thymosins?

A

Q

Target cell/organ of aldosterone?

A

Ascending arm and distal convuluted tubule of nephron -0 kidney

27
Q

Effect of aldosterone

A

Increases active reabsorbtion of NA2+ and excretion of K+

28
