18 Questions
Which inputs contribute to homeostasis for blood pressure and volume?
Both nervous and hormonal inputs
What does antidiuretic hormone (ADH) do?
Increases permeability of collecting ducts
What triggers the release of ADH?
Increase in blood osmolarity
What happens when osmolarity decreases?
ADH secretion decreases
What is the function of ADH in the kidney?
To decrease urine production
Which part of the kidney does ADH affect?
Collecting duct
What happens when ADH is released?
Urine production decreases
What triggers the release of ADH when blood osmolarity increases?
Hormonal inputs
What is the role of ADH in fluid retention in the kidney?
To increase fluid retention
Which peptide is a product of the renin-angiotensin-aldosterone system (RAAS)?
Angiotensin II
What is the effect of angiotensin II on blood pressure and blood flow in the kidney?
Angiotensin II raises blood pressure and decreases blood flow to capillaries in the kidney.
What condition are drugs that block angiotensin II production used to treat?
Hypertension (chronic high blood pressure)
Which system regulates kidney function?
Renin-angiotensin-aldosterone system (RAAS)
What is the role of angiotensin II in the body?
Regulating blood pressure and blood flow
What is the primary function of the renin-angiotensin-aldosterone system (RAAS)?
Regulating kidney function
Which peptide is involved in raising blood pressure?
Angiotensin II
Which drugs are used to treat hypertension?
Drugs that block angiotensin II production
What is the effect of angiotensin II on blood flow to capillaries in the kidney?
Angiotensin II decreases blood flow to capillaries in the kidney.
Test your knowledge on the homeostatic regulation of the kidney! This quiz will cover how a combination of nervous and hormonal inputs help regulate the osmoregulatory function of the kidney, contributing to homeostasis for blood pressure and volume.
