(P2, M1, D1) TASK TWO: Structure, function and interrelationship of 2 major body system the Respiratory System and Cardiovascular system. P2 The Respiratory System The main function of the respiratory system it transport air into the lungs supplying oxygen in the body blood stream and remove the waste carbon dioxide. The structures of the respiratory system are Mouth, Pharynx, Larynx, Trachea, Bronchi, Bronchioles, Alveoli, and Diaphragm and they are divided into the upper and lower. The two important structures in the respiratory system are the Larynx and lungs. Air enters the respiratory system through the mouth and the noses by breathing were it is warmed and moistened. The air then passes through the larynx (voice box) and the trachea (wind pipe) which is a tube that enters the thorax. In the thorax, the trachea splits into two smaller tubes called the bronchi. Each bronchus then divides forming the bronchial tubes. The bronchial tubes leads direct into the lungs where they divide into many smaller tubes which connect to smaller…show more content…
The respiratory system's organs which include the Nostril Nasal Cavity pharynx, Larynx, Trachea, Bronchi and Alveoli work together which enables humans to survive and allows us to breathe by taking air in through the nostrils going down through the Trachea down the Bronchi before entering the Bronchiole which leads to the Alveoli to pump oxygen into the blood for the system to use it's function. The main function of the lung and heart is to take oxygen into the body, which we need for our cells to live and function properly, and to help us get rid of carbon dioxide, which is a waste product. Everyone has two lungs, a left lung and a right lung. These are divided up into sections of tissue separated. The right lung has three divisions but the left lung has only two, because the heart takes up some of the space in the left side of the
