If you take just one away, the whole body will cease to work properly. The main systems are the nervous, respiratory, circulatory, immune, digestive, excretory, skeletal, muscular, and the reproductive system. One of them is the respiratory system. This is the system that deals with breathing and the respiration process. They all work together in harmony and unison to keep us alive.

Human respiratory system


The respiratory system, transports air to our lungs and diffuses oxygen into our blood. It also removes carbon dioxide. This system is also known as the “Gas Exchange System”. You inhale oxygen and exhale carbon dioxide. There are four processes. The first, is breathing in with your nose, the air then travels down your windpipe. Then the diaphragm, which flattens out making the lungs expand and fill with air. Afterwards, the air travels to our lungs into the bronchi.

The alveoli allow oxygen to be passed into the red blood cells while the carbon dioxide is getting diffused out. The system consists of the nose, pharynx, larynx, trachea, lungs, and diaphragm. In the lungs are bronchi, bronchides, and alveoli. The nose filters, moistens, and warms the air. The pharynx is where the trachea and the esophagus divide into two.

The larynx is the voice box. The trachea is the windpipe where air travels from the throat to the lungs. The bronchi are the major air passages that lead to lungs and that diverge from the windpipe. The lungs are a pair of organs that consists of two elastic sacs with two passages. That is where the oxygen gets absorbed and the carbon dioxide removed. The diaphragm plays a major role in breathing, because it increases the volume of the chest and inflates the lungs. Alveoli are located in the bronchioles. The bronchioles are bronchi that divide into narrower bronchioles and the decreased airflow of one who has asthma. The respiratory system serves an essential purpose to the human body.
