BREATHING MECHANISM #bsbiostudio #biologyeducation #anatomybasics #ventilation #breathingprocess

Breathing involves two main phases: inhalation and exhalation. During inhalation, the diaphragm contracts and moves downward while the intercostal muscles expand the rib cage, increasing chest volume and lowering pressure, causing air to rush into the lungs. During exhalation, the diaphragm and intercostal muscles relax, the chest cavity volume decreases, pressure increases, and air is pushed out of the lungs. This entire process ensures a continuous exchange of oxygen and carbon dioxide.
