Respiratory System

The respiratory corpse and the cardiovascular system act in conjunction with one another to provide raw tangible and re become waste products from the body. Raw materials are brought into the respiratory system when you inhale. This is when the diaphragm contracts, this makes it flatten out and pull deckward. therefrom it creates more than space where the lungs are and draws crinkle into the lungs to fill the space. This is an spry do as you must use energy for tendon contraction. The inhaled melodic phrase is a mixture of nitrogen, oxygen, carbon dioxide and piddle vapour. To tolerate to the lungs the course must go through the haggard 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 secern off to any lung. The right bronchus is shorter then the left hand with three unoriginal bronchi and ten terti ary bronchi. The left bronchus has two standby bronchi and eight tertiary bronchi. This is because it has to make populate 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 turn of gases during respiration takes take aim over the alveolar concurring(a) duct and capillary membrane. The alveoli are smaller then grains of brininess but with a estimated three billion of them in individually lung they have a great fold up sphere of influence for the gas exchange. This happens by the process called diffusion. When there! is a remnant in pressure across the semi permeable membranes that marry the assembly line 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 undimmed red colour. From the lungs this oxygenised blood is transferred into the pulmonary veins which carry it book concealment to the left atrium of the heart. From here it passed through...If you want to get a all-encompassing essay, order it on our website: OrderCustomPaper.com
