Q

What is the difference between exocrine and endocrine glands?

A

Q

Describe the renin-angiotensin-aldosterone system:

A
  1. Drop in BP triggers JGA to secrete renin
  2. Renin converts angiotensinogen to angiotensin I
  3. Angiotensin-Converting Enzyme (ACE) in lung capillaries converts angiotensin I to angiotensin II
  4. Angiotensin II circulates to adrenal cortex and triggers secretion of aldosterone
  5. Aldosterone causes kidney to retain sodium and water, increasing BP

Q

What is the endocrine portion of the pancreas called?

A

Islets of Langerhans

26
Q

What are the five primary types of endocrine cells in the pancreatic islets?

A
  1. alpha cells (secrete glucagon)
  2. beta cells (secrete insulin)
  3. delta cells (secrete somatostatin)
  4. epsilon cells (secrete ghrelin)
  5. pancreatic polypeptide cells (secrete pancreatic polypeptide)
27
Q

How does a healthy body regulate low blood sugar?

A

-Low blood sugar detected
-Increased glucagon production by alpha cells

-Glucose levels in blood increase

28
Q

How does a healthy body regulate high blood sugar?

A

-High blood sugar detected
-Increased insulin production by beta cells
-Decreased glucagon production by alpha cells
-Glucose uptake by cells increases
-Glucose release by liver decreases
