When someone is hot and their face is red, it is due to capillaries bringing blood closer to the surface of our skin so more heat can be lost. In the video, learners explore homeostasis and its role in the human body. Four homeostatic loops are important in biology—temperature, blood glucose, blood calcium, and osmolarity  and scholars see how these work to maintain a stable internal environment in the body.
