The gas exchange system is made from key parts, each of which has a different function. Bronchus The trachea splits into a left and right bronchus (plural: bronchi), each leads to a lung.

Our findings highlight divergent trends, such as the global reduction in tobacco-associated mortality but rising mortality linked to ambient particulate matter,” researchers wrote.
