Respiratory Volumes Types and Definitions

Respiratory Volumes Types and Definitions

The contraction of the diaphragm and the inter coastal muscles produces expansion of the chest cavity, so air enters into the lungs during inspiration. A forced inspiration can produce additional expansion, so more air can enter the lungs . Similarly, a forced expiration can expel an extra volume of air. The various respiratory volumes are: […]

Regulation of Respiration, Musculature, Blood Vessels and Glands of Airways

Regulation of Respiration Respiration is regulated by the rhythmic discharges from the respiratory centre in the medulla. The discharges are modulated by input from pontine and higher central nervous system (CNS) centers and vagal afferents from the lungs. Various chemical factors affect the respiratory centre, including the partial pressure of carbon dioxide in the arterial blood by […]

Mechanism of Human Respiration

Mechanism of Human Respiration Oxygen is required by the cells for oxidising the food and to release the energy. The cells cannot utilise the oxygen directly. Air is taken into the lungs first and the oxygen present in the air diffuses into the blood and the carbondioxide diffuses out. This part of respiration is called […]
