Respiratory System
The Respiratory System is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The process of respiration in humans involves the inhalation and exhalation of air, absorption of oxygen from air in the lungs, and the discharge of carbon dioxide back into the air.
Anatomy[edit | edit source]
The human respiratory system is made up of the nose, nasal cavity, pharynx, larynx, trachea, bronchi, and lungs. It also includes the muscles of respiration, including the diaphragm and intercostal muscles.
Function[edit | edit source]
The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide.
Diseases[edit | edit source]
There are many diseases and conditions that can affect the respiratory system, such as asthma, chronic obstructive pulmonary disease (COPD), lung cancer, pneumonia, tuberculosis, and COVID-19.
