Pharynx : the membrane-lined cavity behind the nose and mouth, connecting them to the oesophagus.
Larynx : voice box
trachea: It is a cartilaginous tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from the larynx and branches into the two primary bronchi.
Bronchi : is the two tube like structures
Bronchioles : the bronchi which is further divided into bronchioles the tiny tube like structures
alveoli : they are sac like structures where exchange of gas takes place and it is reachly supplied with blood vessels
lungs : there are pair of lungs in our body . they expand when we inhale and come to their original position when we expire.
diaphragm : The diaphragm is a thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest. It contracts and flattens when you inhale. This creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes and the air is pushed out of lungs.
