and into lungs. Through your bronchial tubes it helps the air to reach and enter the alveoli or air sacs. Oxygen from the air passes to the surrounding capillaries (blood vessels) by through the walls of the alveoli which are very thin. It is the hemoglobin which is a red blood cell protein that move oxygen from the alveoli to the blood. Also‚ the carbon dioxide moves from the capillaries into alveoli

Jaundice in Newborns Jaundice is caused by an increase in blood levels of bilirubin‚ which is a waste product made when haemoglobin in red blood cells is broken down. Newborn babies have immature liver enzymes and are unable to chemically transform (metabolise) this bilirubin effectively for later excretion. Babies who are born underweight and those born to diabetic mothers are particularly likely to become jaundiced. Physiological Jaundice A natural build-up of unmetabolised bilirubin is

loss of body fluid and consequently blood plasma volume. The reduced blood plasma volume inhibits the ability to continue to deliver blood to both the working muscles and the periphery for cooling via sweat evaporation. In addition‚ there is a decreased stroke volume‚ leading to an increased heart rate to compensate. With significantly reduced plasma volume‚ the body will priorities blood supply to the working muscles‚ rather than the periphery. This means less blood flow to the skin‚ limiting further

water and on the ground. As we have learned in class‚ companies are still using nitrites in the meat in order to increase sales. Sodium nitrite is put on meat to keep its attractive red color by preventing oxidation. The same process takes place in our body where it will prevent oxygen from reaching the red blood cells. This can be dangerous to adults‚ but more specifically to babies. Therefore‚ it is illegal to use nitrites on fresh meat but it can still be used on packaged meats. Another health
