A. Rh incompatibility is only an issue with Rh negative fetuses. B. Rh incompatibility is only an issue with Rh positive fetuses. C. sinsitization has not occured D.  Rh incompatibility is only an issue with Rh positive mothers

Blood flow is ________ proportional to blood pressure and ________ proportional to peripheral resistance

A. directly; directly B. directly; inversely C. inversely; directly D. inversely; inversely

Explanation / Answer

1) Atrial natriuretic peptide increases sodium excretion in urine thereby increasing the urinary output and decreasing extracellular fluid volume. It also causes vasodilation and inhibits the secretion of ADH. So, the answer for this question is option A (decrease water volume of urine).

2) Coeliac trunk does not supply renal artery (option B).

3) Blood can be diverted from tissues by pre-capillary sphincter.

4) Problems do not develop for Rh negative mother during their first pregnancy with Rh positive fetus because sensitisation has not ocurred.

5) Blood flow is directly proportional to blood pressure and inversely proportional to peripheral resistance.
