Angiotensin II is responsible for maintaining blood pressure and stimulating aldosterone secretion. Parathyroid hormone is important in calcium homeostasis.

e
Promoting water excretion by the kidneys
QuestionChoice
Angiotensin II is a hormone that is part of the renin-angiotensin-aldosterone system (RAAS) and is primarily responsible for increasing blood pressure and stimulating the secretion of aldosterone. When the body detects a decrease in blood pressure or blood volume, the kidney releases renin which converts angiotensinogen into angiotensin I. Angiotensin-converting enzyme (ACE) then converts angiotensin I into angiotensin II which causes vasoconstriction, increased sodium reabsorption, and increased water retention in the kidneys.

a
Maintaining blood pressure
QuestionChoice
Angiotensin II is not involved in this process. RAnaemia, ischaemic stress and high altitude can all promote erythropoiesis in the bone marrow. Erythropoiesis is stimulated by erythropoietin.
