The respiratory system is responsible for the exchange of gases between the body and the environment. It includes the nose, pharynx, larynx, trachea, bronchi, and lungs. The primary function of the respiratory system is to supply the body with oxygen and dispose of carbon dioxide, a waste product of cellular metabolism.
The respiratory process involves breathing, gas exchange, and cellular respiration. When we inhale, air enters the respiratory system and travels through the various parts, eventually reaching the lungs. In the lungs, oxygen from the air is transferred to the blood, and carbon dioxide is removed from the blood and exhaled out of the body during exhalation.
Here are some key points to remember about the respiratory system:
Understanding the respiratory system is important for maintaining overall health and well-being. It is essential for the delivery of oxygen to the body's cells and the removal of carbon dioxide, a waste product of metabolism.
