ANATOMY

Detailed explanation-1: -The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart.

Detailed explanation-2: -The Circulatory System Helps Regulate Body Temperature Directed by the brain, the circulatory system can help warm or cool the body as it transports blood. By dilating the blood vessels, heat from blood can be more readily released to the environment. To keep the heat in, blood vessels constrict.

Detailed explanation-3: -Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.

Detailed explanation-4: -Drink cool liquids. Go somewhere with cooler air. Get in cool water. Apply cold to key points on the body. Move less. Wear lighter, more breathable clothing. Take heat regulating supplements. Talk to a doctor about thyroid health.
