• Structural proteins

What function does the circulatory system have in regulating body temperature?

• The circulatory system has no relation to body temperature.

• The circulatory system regulates body temperature by redistributing blood to release or conserve heat.

• Body temperature is regulated exclusively through the skin.

What type of blood do veins transport?

• Deoxygenated blood

• Lymphocytes

• Oxygenated blood

• Plasma

What is the role of hormones in the circulatory system?

• Hormones have no impact on the regulation of the body.

• Hormones regulate bodily functions and maintain homeostasis through the circulatory system.

• Hormones are responsible for the production of red blood cells.

• Hormones only affect the digestive system.

What are capillaries and what is their function?

• Capillaries are cells that fight infections.

• Capillaries are organs that produce hormones.

• Capillaries are blood vessels that allow the exchange of substances between blood and tissues.

• Capillaries are large arteries that transport oxygenated blood.

How does the circulatory system help in maintaining pH balance?

• The circulatory system has no relation to pH.

• The circulatory system only transports nutrients.

• The circulatory system removes oxygen from the body.

• The circulatory system helps regulate pH by transporting carbon dioxide and facilitating its removal.
