the implantation bleeding occurs in the moment when the fertilized egg gets implanted into the sensitive lining of the uterus similarly the length of the bleeding could also vary from one case to the other it is possible for the bleeding to be brief and hardly noticeable
Angiotensin is a peptide hormone that causes vasoconstriction and a subsequent increase in blood pressure. It is part of the renin-angiotensin system, which is a major target for drugs that lower blood pressure. Angiotensin also stimulates the release of aldosterone, another hormone, from the adrenal cortex.
Angiotensin II causes blood vessels to contract -- the increased blood vessel constrictions elevate the blood pressure. Â­Â­Now let's take a look at how the kidney increases the circulating blood volume. Angiotensin II also stimulates the adrenal gland to secrete a hormone called aldosterone. Aldosterone stimulates more Na reabsorption in the distal tubule, and water gets reabsorbed along with the Na.
