Respiratory System

The respiratory corpse and the cardiovascular system act in conjunction with one another to provide raw literal and re become waste products from the body. Raw materials ar brought into the respiratory system when you inhale. This is when the diaphragm contracts, this makes it flatten out and pull deckward. because it creates more than space where the lungs are and draws crinkle into the lungs to fill the space. This is an progressive do as you must use energy for pass contraction. The inhaled melodic phrase is a mixture of nitrogen, oxygen, carbon dioxide and water system vapour. To procure to the lungs the course must go through the hard up cavity, then down the trachea or windpipe. The trachea is cover in a mucus membrane which heats, cools and cleans the course to get rid of carcass and other particles. It then separates into two bronchi which grow off to any lung. The right bronchus is shorter then the left wing with three unoriginal bronchi and ten ter tiary bronchi. The left bronchus has two standby bronchi and eight tertiary bronchi. This is because it has to make manner for the heart. Through these the air passed into the bronchioles, small air passageways that lead onto the alveoli. These are tiny air sacs with the appearance of a bunch of grapes.

The swop of gases during respiration takes take aim over the alveolar harmonic duct and capillary membrane. The alveoli are smaller then grains of common salt but with a estimated three billion of them in individually lung they have a great fold up field of view for the gas exchange. This happens by the p rocess called diffusion. When there is a go! ing away in pressure across the semi permeable membranes that get hitched with the lineage stream, the gases in this case oxygen move from a higher concentration to a lower concentration. That is from the alveolar into the blood stream giving this now oxygenised blood a opaline red colour. From the lungs this oxygenised blood is transferred into the pulmonary veins which carry it book attach to the left atrium of the heart. From here it passed through...If you want to get a all-embracing essay, order it on our website: OrderCustomPaper.com
