Respiration in humans is the process by which oxygen is taken in from the air and carbon dioxide is expelled from the body. It involves the exchange of gases between the lungs and the blood, as well as between the blood and the body's tissues. Respiration is essential for providing the body with the oxygen it needs to produce energy and removing waste carbon dioxide from the body. It is controlled by the respiratory system, which includes the lungs, diaphragm, and other muscles involved in breathing.

Respiration in Humans
Respiration is a vital process that involves the exchange of gases between the body and the environment. It consists of two main phases:
1. Gas Exchange:
- Inhalation: Air is drawn into the lungs through the nose or mouth, passing through the trachea and bronchi into the alveoli, tiny air sacs in the lungs.
- Exhalation: Carbon dioxide-rich air is expelled from the alveoli through the bronchi, trachea, and nose or mouth.
2. Cellular Respiration:
- Oxygen Transport: Oxygen absorbed in the alveoli is transported to cells via red blood cells in the bloodstream.
- Carbon Dioxide Transport: Carbon dioxide, a waste product of cellular metabolism, is transported from cells to the alveoli in the bloodstream.
Process Overview:
1. Inhalation: Diaphragm and intercostal muscles contract, increasing the volume of the thorax.
2. Gas Exchange in Lungs: Oxygen diffuses from alveoli into capillaries surrounding them, while carbon dioxide diffuses in the opposite direction.
3. Oxygen Transport: Oxygen-rich blood is carried by arteries to the heart and then to all body cells.
4. Carbon Dioxide Transport: Carbon dioxide-rich blood is carried by veins to the heart and then to the lungs.
5. Exhalation: Diaphragm and intercostal muscles relax, decreasing the volume of the thorax, expelling carbon dioxide-rich air.
Regulation of Respiration:
Respiration is controlled by the respiratory center in the brain. The rate and depth of breathing are adjusted based on various factors, including:
- Blood pH
- Blood carbon dioxide levels
- Blood oxygen levels
- Exercise level
- Stress
Types of Respiration:
- Eupnea: Normal, regular breathing
- Hyperpnea: Increased rate and depth of breathing
- Apnea: Temporary cessation of breathing
- Dyspnea: Difficulty breathing
