Question

QUESTION 12 1 points Save Ans Match the homeostatic compensation pathway component to either severe dehydration, the renin-angiotensin-aldosterone system (RAAS), or both. A Severe dehydration B. RAAS C. Both Response initiated by low blood pressure. Response usually associated with high blood osmolarity Vasopressin is released Angiotensinogen is converted to ANG I in response to renin Water reabsorbtion is high, while sodium reabsorption is low QUESTION 13 1 points Save Ans Match the membrane transporter to its function. A. exchange hydrogen, moving H+ into the lumen against p C. Nat NH4+- antiport NHE Ht ATPase Ht- K+- ATPase Nat HCO3 symporter gradient to Active transporter, uses the Na+ its chemical gradient. Uses the chemical gradient of HCO3 to actively transport HCO3 and Na to the ECF E. JUses ATP to actively pump hydrogen against its concentration gradient. Pumps hydrogen into the lumen and potassium into the nephron cell using AlP as an energy source. Exchanges NH4+ for Na+, moving Na+ into the nephron cell and NH4+ into the lumen.

Explanation / Answer

Answer12:

Response initiated by blood pressure---RAAS

Response usually associated with high blood osmolarity--both

Vasopressin is released--both

Aldosterone is synthesized---both

Angiotensinogen is converted to ANG I in response to renin- RAAS

Water reabsorption is high, while sodium reabsorption is low- RAAS
