    Transcript

    00:02 So to conclude our topic on the respiratory system, we will call that the respiratory system begins at the nasal cavity and ends at the alveoli.

    00:13 It has two main zones the conducting zone where air is being conducted and the respiration zone where respiration is going to occur.

    00:24 The main function of the respiratory system is to exchange gases between the blood and the lungs.

    00:31 This occurs in concert with the circulatory system that exchanges gases between the blood and the tissues.

    00:39 So the respiratory system is more responsible for external respiration while the circulatory system is more responsible for internal respiration.

    00:53 Pulmonary ventilation is going to rely on several different pressures that happened between the outside of the body and the inside of the thoracic cavity.

    01:04 The movement of gases in and out of the thoracic cavity is going to be influenced by Boyle's Law.

    01:15 Gas exchange relies on the partial pressures of gas molecules in between the alveoli and the blood.

    01:23 As well as between the blood and the tissue.

    01:27 The principles of Dalton's law and Henry's law of partial pressures are applied in order to understand how gases move in and out of the alveoli and the blood and the tissues.

    01:42 Most oxygen in the body is going to be carried in the blood by way of hemoglobin.

    01:48 Also carbon dioxide can also be carried on hemoglobin.

    01:53 But most of our carbon dioxide is going to be carried by way of bicarbonate atoms.

    02:00 And finally, respiration is going to be controlled by our higher brain centers are chemoreceptors found in the brain stem as well as in the carotid and aortic bodies and finally by reflexes such as the inflation reflex or reflections in response to chemical irritants.

    02:23 And this concludes our lecture or our topic on the respiratory system.

    02:29 Thank you for listening.
