4 True/False questions
Inspiration → diaphragm relaxes & moves up into original dome shape. This decreases the chest volume & moves air out of the lungs
Vital capacity → Respiratory process by which gases are moved into and out of the lungs.
Expiration → an active process in which the intercostal (rib) muscles and the diaphragm contract, expanding the size of the chest cavity and causing air to flow into the lungs
Cellular Respiration → exchange of O2 and CO2 between the alveoli and circulating blood in the pulmonary capillaries.
