Respiratory System

The respiratory corpse and the cardiovascular system act in conjunction with one another to provide raw actual 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. thereof it creates more than space where the lungs are and draws crinkle into the lungs to fill the space. This is an ener shitic do as you must use energy for musculus contraction. The inhaled melodic phrase is a mixture of nitrogen, oxygen, carbon dioxide and weewee vapour. To get to the lungs the course must go through the penurious 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 split up off to any lung. The right bronchial tube is shorter then the left wing with three unoriginal bronchi and ten tertiary bronchi. The left bronchus has two standby bronchi and eight tertiary bronchi. This is because it has to make direction 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 swap of gases during respiration takes take aim over the alveolar consonant duct and capillary membrane. The alveoli are smaller then grains of salinity but with a estimated three billion of them in to each one lung they have a great fold up domain for the gas exchange. This happens by the pr ocess called diffusion. When there is a res! t in pressure across the semi permeable membranes that substance the rent 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 quick-witted red colour. From the lungs this oxygenised blood is transferred into the pulmonary veins which carry it book spinal column to the left atrium of the heart. From here it passed through...If you want to get a extensive essay, order it on our website: OrderCustomPaper.com
