Answer 2

Blood has three main functions: transport, protection and regulation.

Transport

Blood transports the following substances:

Gases, namely oxygen (O2) and carbon dioxide (CO2), between the lungs and rest of the body

Nutrients from the digestive tract and storage sites to the rest of the body

Waste products to be detoxified or removed by the liver and kidneys

Hormones from the glands in which they are produced to their target cells

Heat to the skin so as to help regulate body temperature
Protection

Blood has several roles in inflammation:

Leucocytes, or white blood cells, destroy invading microorganisms and cancer cells

Antibodies and other proteins destroy pathogenic substances

Platelet factors initiate blood clotting and help minimise blood loss.


Regulation

Blood helps regulate:

pH by interacting with acids and bases

Water balance by transferring water to and from tissues
