What is the respiratory system?
The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. the primary organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe.
Red blood cells collect the oxygen from the lungs and carry it to the parts of the body where it is needed. During this process, the red blood cells collect the carbon dioxide and transport it back to the lungs, where it leaves the body when we exhale. The human body needs oxygen to sustain itself (Zimmermann 2018).
How does the respiratory system work?
The trachea also called the windpipe filters the air that is inhaled. It branches into the bronchi, which are two tubes that carry air into each lung, each one is called a bronchus. The bronchial tube is lined with tiny hair called cilia. Cilia move back and forth, carrying mucus up and down. Mucus is a sticky fluid that collects dust, germs and other matter that has invaded the lung. Mucus is expelled when we sneeze, spit, swallow or cough.
The bronchial tubes lead to the lobes of the lungs. the right lung has three lobes; the left lungs have two. The left lung is smaller to allow room for the heart. Lobes are filled with small, spongy sacs called alveoli, and this is where oxygen and carbon dioxide occurs.
Blood passes through the capillaries. The pulmonary artery carries blood containing carbon dioxide to the air sacs, where the gas moves from the blood to the air. Oxygenated blood goes to the heart through the pulmonary vein, and the heart pumps it through the body.
The diaphragm, a dome-shaped muscle at the bottom of the lungs, controls breathing and separates the chest cavity from the abdominal cavity. when a breath is taken, it flattens out and pills forward, making more space for the lungs. During exhalation, the diaphragm expands and forces air out (Zimmermann 2018).
