Study Notes

Respiration Definitions

Physiological definition: The process of exchanging oxygen and carbon dioxide between the environment and the body's cells.
Biochemical definition: The process of generating energy from the breakdown of glucose and other organic molecules, releasing carbon dioxide and water as byproducts.

Ventilation and Perfusion

Ventilation: The process of moving air in and out of the lungs, facilitating gas exchange between the atmosphere and the alveoli.
Perfusion: The process of blood flowing through the lungs, allowing for the exchange of oxygen and carbon dioxide between the air and the bloodstream.

Pressure Variations during Inhalation

During inhalation, the pressure in the thoracic cavity decreases, causing the lungs to expand and air to enter the lungs.
This pressure variation is caused by the contraction of the diaphragm and the intercostal muscles, which increases the volume of the thoracic cavity.
