Gaseous Exchange University Essay

This essay deeply explores the ideas surrounding gas exchange, mainly focusing on anatomy and the science of it.

The human body’s respiratory system is composed of the lower and upper respiratory system and allows for different vital functions to occur. The lower respiratory system is mainly composed of the larynx, trachea, bronchi and alveoli-containing bronchioles (Brooker, R., Widmaier, E., Graham, L. and Stiling, P., 2018). One of its most important functions is providing a vast surface area that is needed for the exchange of carbon dioxide in our blood and oxygen from the air. This, together with other factors presented by Fick’s Law, provide the features of the lower respiratory system, making it ideal for efficient gas exchange. The respiratory system can be split into two sections- the conducting and the respiratory zone. Whilst the conducting zone involves all the parts leading up to gas exchange, the respiratory zone is where gas exchange occurs (Kumar, V., 2016). It is the lower respiratory system that will be examined in more depth within this essay to explain how its structure allows for its functionality and how things can sometimes go wrong.
