Document Summary

Review function and lung anatomy: focus on pleura, lobes major airways, alveoli. Tissue cells use oxygen to produce carbon dioxide during cellular respiration: pulmonary ventilation (breathing) inspiration (air into the lungs) expiration (air out of the lungs, external respiration. Oxygen diffuses into the lungs to the blood carbon dioxide diffuses from the blood to the lungs: transport of respiratory gases blood is the transporting fluid. O2 goes from the lungs to the tissues cells. Co2 goes from the tissue cells to the lungs: internal respiration. Function supply the body with oxygen, and dispose of carbon dioxide collectively called respiration, done in four processes respiratory system is only responsible for the first two processes, (needs 3 and 4 to occur) rd th. Functional anatomy includes; nose, paranasal sinuses, the pharynx, larynx, trachea, bronchi and their smaller branches, the lungs. The upper respiratory system: nose, paranasal sinuses, pharynx. Nose is the only external visible part of the respiratory system.
