Consequences of High Blood Pressure
www.heart.orgHigh blood pressure is often the first domino in a chain or “domino effect” leading to devastating consequences, like: STROKE HBP can cause blood vessels in the brain to burst or clog more easily. VISION LOSS HBP can strain the vessels in the eyes. HEART FAILURE HBP can cause the heart to enlarge and fail to supply blood to the body. SEXUAL

Intracranial Hemorrhage in the Neonate
www.academyofneonatalnursing.orgminal matrix normally has a rich blood supply until the fetus matures, at which point blood flow redistributes. in the pre-mature neonate, the blood vessels of the germinal matrix lack significant structural support, which increases the risk of rupture, especially in the setting of altered cerebral blood flow autoregulation.13
Smoking and Cardiovascular Disease

In extreme cases, an infected limb must be removed. Smoking is the most common preventable cause of PAD. Abdominal Aortic Aneurysm. is a bulge or weakened area that occurs

Blood: Its Composition and Function
stdenis.weebly.comblood vessels. As more and more platelets stick, a clot is created to seal the hole in the vessel. Once the temporary clot is in place, fibrinogen in the plasma is converted into ling strands of fibrin, forming a mesh that traps more platelets and blood cells. This permanent clot stops the leakage of blood and allows time for the injury to heal.
Blood vessels: the endothelium - Yale University
medcell.med.yale.eduBlood vessels are leaky to most ions, so there is no difference in osmotic pressure between blood and surrounding tissue. To counter the hydrostatic pressure, blood retains a high concentration of protein to generate oncotic pressure that draws water into the vessel. Maintaining oncotic pressure requires keeping a high protein concentration ...
