Percutaneous Coronary Angioplasty or PCA‚ is a procedure done to help blood flow toward the heart. This is usually done to people who have heart problems that are due to blockages like coronary heart disease. In coronary heart disease‚ people who have not been taking care of themselves before are likely to develop plaques from cholesterol and other substances found in the blood. When these plaques harden‚ the blood vessels are narrowed and blood flow is then reduced causing the heart to function atypically

Blood Cells Leukocytes (WBC’s) Leukocytes also known as white blood cells (WBCs) are cells which play a defensive roll in the body against injury and infection. They migrate towards tissues where they are needed and become functional performing various activities. WBCs can be divided into 2 groups: Polymorphonuclear granulocytes and mononuclear agranulocytes. Both types are spherical while suspended in blood plasma but when they invade tissues after leaving the blood vessels they become amoeboid

Comparison of different types of blood pumps Nowadays‚ there are two main types of blood pumps: kinetic pumps and positive displacement pumps. Kinetic pumps: Centrifugal pump is one of the most familiar kinetic pumps. A centrifugal pump converts the input power to kinetic energy in the liquid by accelerating the liquid by a revolving device - an impeller. The most common type is the volute pump. Fluid enters the pump through the eye of the impeller which rotates at high speed. The fluid is accelerated
