MICROANATOMY

Detailed explanation-1: -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-2: -The purpose of the cardiovascular system is to provide adequate circulation of blood through the body. Pulmonary circulation allows for the oxygenation of the blood, and systemic circulation provides for oxygenated blood and nutrients to reach the rest of the body.

Detailed explanation-3: -Keeping your cool On a hot day, your cardiovascular system ramps up its efforts to radiate heat to cool you down. Your heart beats faster and pumps harder, and may circulate two to four times as much blood each minute as it does on a cool day.

Detailed explanation-4: -Set your thermostat to at least 68°F to 70°F. Wear layers of loose-fitting clothes around the house, and warm clothes when you are sleeping. Drink warm beverages, but avoid alcohol, which can increase heat loss from your body. More items
