Heart disease‚ strokes and high blood pressure The heart: Our heart is a vital organ; it is a super muscle which constantly pumps our blood around our body at a rate of 40 to 100 beats per minute for a lifetime. It never tires. The heart has two sides which are separated and each side has two chambers. Valves make sure blood can only flow in one direction. The right side receives de-oxygenated blood from the body through the vena cava and pumps it through the pulmonary artery to the lungs‚ and the

Lifestyle Disease A lifestyle disease is one where a person’s choice in how they live their life – what they eat‚ how they socialize‚ where they work‚ how they care of themselves – either causes or increases their chances of contracting. This makes them different from other diseases which are caused by things such as genetics (inherited from family background) or chance (like catching a cold from a friend). Modern life increases the number of people with lifestyle diseases. An industrialized

Bacterial cells are Prokaryotic cells. These cells have several internal structures and surface structures. The cell walls are of two types‚ gram positive and gram negative. Out of all the structures‚ the two selected structures are the cell- wall and endospores. The cell- wall of bacterial cells is found in three distinct shapes such as spherical‚ spiral and rod shaped. The cell wall of the bacterial cells is composed of the proteins and polysaccharides. This is collectively called peptidoglycan

characteristics of a healthy cell and a cancer cell is very different. Healthy cells stop reproducing when there are enough cells‚ however‚ cancer cells continue to reproduce. Due to this continued growth a tumor‚ which is a cluster of cancer cells‚ is formed. Cancer cells do not interact with other cells like the healthy cells. Healthy cells stop growing when they hear signals from the nearby cells‚ in contrast‚ cancer cells do not respond to these signals. When healthy cells get old or damaged they
