Homework 1

Blood is essential for the transport of oxygen, carbon dioxide through the body, necessary for gaseous exchange or cellular respiration. Arteries carry blood rich in oxygen (attached to haemoglobin molecules that are on the red blood cells) from the lungs and through the body, where it moves to capillaries and diffuses into the muscles and cells. Carbon dioxide, as a waste product from cellular respiration, is pumped through the veins back to the lungs, for the blood to be re-oxygenated. It is absolutely necessary that the Carbon Dioxide is removed through external gaseous exchange as the build up of the gas will cause the lowering of the pH of the blood, therefore making the blood acidic. Gaseous exchange in blood is therefore necessary for the maintenance of the pH of the blood, and therefore homeostasis.

Analysis of blood gases can be used to determine potentially the site of the wound, for example whether it was an artery or vein, can also help (with other factors) determine the rough time of death, and whether the victim had consumed alcohol or even poison that may have caused the death. Therefore, respiration is of vital importance to maintain the correct pH of blood, and Blood Gas Analysis is helpful in determining when and how a death occurred.
