'Bifurcate' means 'split or divide into two'. The trachea bifurcates at T5 and T7 vertebral level. It is the point where the trachea splits in two so that air can enter the left and right side seperately. It is like a back up system that the body has so that one side can still function if the other side fails. 'Bifurcate' means 'split or divide into two'. The trachea bifurcates at T5 and T7 vertebral level. It is the point where the trachea splits in two so.
The trachea divides into two bronchi one for the right and one for the left lung, which then progressively subdivide into a system of smaller secondary and tertiary bronchi and smaller bronchioles. This division ends in alveoli, which are thin-walled sacs where gas exchange of carbon dioxide and oxygen, takes place.
