Veterinary science students have been studying the circulatory system in their latest unit of study. One of the objectives was to learn about the topic of external respiration.
In their lab the students learned external respiration is how your body rids itself of the carbon dioxide produced in cells and acquires more oxygen to fuel the cells. This exchange of gases occurs through the process of diffusion in your lungs where the alveoli and capillaries meet.
“This was a lab activity in which the students used a series of scientific processes to collect and analyze data,” said Brad Taylor, agriculture education instructor.
