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 muscles in most arteries, including the arteries of the heart, to contract, thereby narrowing the arteries and elevating blood pressure. ACE inhibitors such as lisinopril lower blood pressure by reducing the production of angiotensin II, thereby relaxing arterial muscle and enlarging arteries. When the blood pressure is lower, the heart - including the failing heart - does not have to work as hard to pump blood.
