What is hypertension, how it occurs and how does it affect you both physically and psychologically.
Blood is a fluid tissue that carries oxygen and nutrients to all cells of the body and also removes waste gases like carbon dioxide from the body. The blood is carried to all parts of the body through tube-like structures called blood vessels. The human body has three types of blood vessels: arteries, veins, and capillaries.
Arteries carry oxygenated blood, while veins carry deoxygenated blood. Capillaries are those blood vessels that connect arteries and veins; they also help in the exchange of materials like oxygen, carbon dioxide, and nutrients between blood and tissue cells.
Blood pressure is defined as the pressure exerted by the blood against the wall of the arteries when it flows through them during each heartbeat.
