Every cell in the body goes through a life cycle. Cells grow and divide to replace cells that are lost because of normal wear and tear or injury to them. All cells grow and die at different rates. The cell cycle can be divided into three periods: interphase‚ the mitotic phase‚ and cytokinesis. During interphase‚ the cell grows‚ accumulating nutrients needed for mitosis‚ preparing it for cell division and duplicating its DNA. During the mitotic phase‚ the cell splits itself into two distinct daughter

Respiratory System Respiration: The primary function of the respiratory system is to obtain oxygen gas for cell metabolism and remove carbon dioxide waste. Describe each of the following general processes of respiration. Ventilation- air is moved into and out of the lungs so the gases there are continuously changed and refreshed external respiration- oxygen diffuses from the lungs to the blood‚ and carbon dioxide diffuses from the blood to the lungs gas transport- oxygen is transported

Recent studies of stem cells have played are very important because they show promise in helping man solve or at least grasp the solution to the diseases that have haunted him since his early days of conscious. The idea of stem cells is kind of a simple idea. This brings us to the first promise‚ not only are stem cells able to be taken from the human body‚ but scientists are now able to grow these cells in labs. The most worried over part is that when obtaining the cells‚ it doesn’t always

Stem cells are unique because they have the ability to generate new cells of any kind during early life and growth. There are about 200 different types of cells in the body; such as muscle‚ skin and brain cells. Most of these cells have to be repaired or replaced once in a while. For example our taste buds are replaced every 10 days‚ skin cells every couple of weeks and liver cells every 300-500 days. Stem cells serve as an internal repair system dividing essentially without limit to replenish
