area of human skin. This provides sufficient surface area for gas exchange to occur. Gas exchange occurs here with the help of a dense network of capillaries surrounding the alveoli. Blood arriving in the alveoli is deoxygenated‚ produced during respiration‚ however‚ the blood already contained in the alveoli is oxygenated. Therefore‚ the oxygen enters the deoxygenated blood by diffusion. As the oxygen diffuses through the cell membrane and into the blood‚ each oxygen molecule merges with a haemoglobin

walking sticks and umbrellas are very common. It is also found out that the young people forget more than the older ones and the sportsmen and anglers have worse memories than the ordinary serious minded people. A considerable number of lost balls‚ cricket bats and fishing rods left in trains illustrate this fact.

There is around 4% of every breathe that the body intakes the oxygen is absorbed into the blood. There are two body systems that are involved in the getting the oxygen and energy into the blood‚ respiratory and digestive system. The role of a respiratory system goes through many steps before the oxygen gets into the blood. The first step is when the air enters the nose and mouth and travels down into through the pharynx‚ larynx and towards the trachea. After it pasts the trachea‚ the air will travel

Hence the respiratory system keeps on working without any rest and relaxation there by keeping living being in life and activity. The rate of breathing or cellular respiration varies with level of activity not only physical but also mental. Main organ of the respiratory system can be stated as below: 1. Nostrils 2. Pharynx Nasal and Oral 3. Glottis 4. Trachea 5. Bronchi 6. Alveoli 7. Lung During breathing
