Endocrine pt. 2 Flashcards
Endocrine Role of: Kidneys
Erythropoietin, Glycoprotein
Stimulated by low blood oxygen
Targets bone marrow to stimulate RBC production
What produces male sex hormones
Androgen
Endocrine Role of: Small intestine
The peptide Secretin
Targets pancreas to stimulate enzyme-rich juice
Increases bile in the liver
Reduces secretions and mobility in stomach
Endocrine Role of: Stomach
The peptide Gastrin,
Targets gastric glands to secrete HCL
Endocrine Role of: Cholecystokinin (CCK)
Stimulates release of bicarbonate in pancreas
Stimulates expulsion of bile in gallbladder
Causes duodenal papilla sphincter to relax
Endocrine Role of: Heart
ANP produced by the heart
Atrial stretching stimulates the secretion
Targets Kidneys to secrete aldosterone
Inhibits release of Renin
Why is Renin angiotensin mechanism important
It regulates blood pressure
Initiated by Juxtagolmerular apparatus (JGA)
What is the most important trigger for the release of Aldoesterone
Renin angiotensin mechanism
What stimulates JGA cells
Low blood pressure
What is renin
An enzyme catalyst for reactions that produce angiotension II
