The Cardiovascular and Respiratory Systems module aims to describe the organization of the cardiovascular and respiratory systems, their structures and functions. The students will be able to name the organs forming the respiratory passageway from the nasal cavity to the alveoli of the lungs. The circulatory and the respiratory system work closely to ensure that the organ tissues receive enough oxygen and the students will learn about the biochemistry of these two systems’ mechanism. Mechanism of gas exchange, respiratory volumes and capacity, respiratory resistance and also thermodynamics will be taught in this module.
