Detailed explanation-1: -The movement of air in and out of lungs is called breathing. Breathing has two components: inhalation and exhalation. Inhalation in taking the air inside the lungs. Exhalation is giving the air out of the lungs.

Detailed explanation-2: -Pulmonary ventilation It is the process of air flowing into the lungs during inspiration (inhalation) and out of the lungs during expiration (exhalation). Air flows because of pressure differences between the atmosphere and the gases inside the lungs.

Detailed explanation-3: -Pulmonary ventilation, more commonly referred to as breathing, is the movement of air into and out of the lungs. Inhalation is the act of drawing air into the lungs, while exhalation is the expulsion of that air out of the lungs.

Detailed explanation-4: -When you inhale through your nose or mouth, air travels down your pharynx (back of your throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into two air passages called bronchial tubes. One bronchial tube leads to your left lung, the other to your right lung.
