In this quick and easy biology final exam study guide, we share our notes and review the circulatory, respiratory, and lymphatic systems in the following 3 sections. From the anatomy of the heart and blood flow in the circulatory system to the breaths we take traveling through the lung and lymphatic flow.
In this lesson, we will explain the differences between the upper and lower respiratory system and the differences between upper respiratory tract infections and lower respiratory tract infections.
What is the respiratory system? In general, the respiratory system is a biological system that contains organs and structures that assist in gas exchange. Gas exchange involves the movement of carbon dioxide and oxygen between our circulating blood and air. In this educational lesson, we explore seven general functions of our respiratory system.
