Human breathing mechanism
WebDuring inhalation process, the diaphragm contracts and moves down. The ribcage moves upwards and outwards and expands. This results in increasing the volume of the chest cavity and reduces the pressure inside it as volume is inversely proportional to pressure.When the lungs inhale, the diaphragm contracts and pulls downward.

WebThe process of breathing does not fill the alveoli with atmospheric air during each inhalation (about 350 ml per breath), but the inhaled air is carefully diluted and thoroughly mixed with a large volume of gas (about 2.5 liters in adult humans) known as the functional residual capacity which remains in the lungs after each exhalation, and whose gaseous … Breathing (or ventilation) is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen. All aerobic creatures need oxygen for cellular respiration, which extracts energy from the reaction of oxygen with molecules derived from food and produces carbon dioxide as a waste product. Breathing, or "external respiration", brings air into the lungs where gas exchange takes place in …
