What is cardiovascular disease? Cardiovascular disease (CVD) refers to a cluster of disorders affecting the heart and blood vessels, including coronary heart disease (CHD) - restriction of blood flow to the heart, cerebrovascular disease - restriction of blood flow to a region of the brain, and peripheral vascular disease - restriction of blood flow to the arms and legs.

Atherosclerosis is a chronic condition that can...
Introduction The miracle of human life is made possible by the cell membrane. It is the defining feature of all cellular life forms. It acts to compartmentalise tissue into distinct structures each with a specialised biological function. The human body is home to over 200 different cell types, each with a unique role (see figure 1). The muscle cell provides movement, the nerve cell communicates with the muscle cell to produce that movement, cells of our skin protect us from the ravages of the external environment and the blood cell acts to transport oxygen throughout our body. The role...
