ANF mechanism, acts as a check on the 

Statement (A): Atrial natriuretic peptide (ANP) mechanism acts as a counter check on the RAAS (Renin-Angiotensin-Aldosterone system). Statement (B) : ANP causes contraction of vascular smooth muscles.

The functions of kidney is efficiently regulated by hormonal feed back mechanism involving the hypothalamus, JGA and heart. Br Mention the feed back which act as a check on the above mechanism.

ANF causes

Assertion :- Feedback mechanism for regulartion of kidney involve hypothalamus & JGA. Reason :- ANF mechanism check renin-angiotensin mechanism.

Which of the following is true about Atrial Natriuretic Factor (ANF)? (a) An increase in blood volume and B.P. stimulates cardiac atria to release ANF (b) ANF promotes vasoconstriction and thereby decrease B.P (c) ANF acts as a check on RAAS (d) a and c

Assertion: The kidneys have built in mechanisms for the regulation of glomerular filtration rate (GFR). Reason: ANF mechanism is one such efficient mechanism.

Assertion: The kidneys have built in mechanisms for the regulation of lomerular filtration rate (GFR). Reason: ANF mechanism is one such efficient mechanism.

Assertion: The kidneys have built in mechanisms for the regulation of glomerular filtration rate (GFR). Reason: ANF mechanism is one such efficient mechanism.
