|
|
Term
islet of langerhans is what type of gland and what 3 cells belong to this group |
|
Definition
endocrine gland, beta, alpha, and delta |
|
|
Term
what do the beta cells do |
|
Definition
secrete insulin and amylin, lowers blood gluclose levels and stimulates the liver to store excess gluclose the amylin works syngergistically with insulin to lower blood gluclose |
|
|
Term
what do the alpha cells secret and what does this help to do |
|
Definition
secretes glucagon, maintains blood gluclose by increasing the release of gluclose from the liver into the blood |
|
|
Term
