*Gases, namely oxygen (O₂) and carbon dioxide (CO₂), between the lungs and rest of the body
*Waste products to be detoxified or removed by the liver and kidneys
*Nutrients from the digestive tract and storage sites to the rest of the body
*Hormones from the glands in which they are produced to their target cells
*Heat to the skin so as to help regulate body temperature

*Leukocytes, or white blood cells, destroy invading microorganisms
*Antibodies and other proteins destroy pathogenic substances
*Platelet factors initiate blood clotting and help minimise blood loss]]> 2017-03-28 10:14:08 UTC https://padlet.com/20294941/1ws20xb7ra9d/wish/163064439 20294941 https://padlet.com/20294941/1ws20xb7ra9d/wish/163064933 Blood helps regulate:
*pH by interacting with acids and bases
*Water balance by transferring water to and from tissues]]> 2017-03-28 10:16:24 UTC https://padlet.com/20294941/1ws20xb7ra9d/wish/163064933 20294941 https://padlet.com/20294941/1ws20xb7ra9d/wish/163065277

They are an important reserve supply of amino acids for cell nutrition. Cells called macrophages in the liver, gut, spleen, lungs and lymphatic tissue can break down plasma proteins so as to release their amino acids. These amino acids are used by other cells to synthesise new products]]> 2017-03-28 10:21:55 UTC https://padlet.com/20294941/1ws20xb7ra9d/wish/163066051 20294941 https://padlet.com/20294941/1ws20xb7ra9d/wish/163066605 Red blood cells also known as erythrocytes, have two main functions:
*To pick up oxygen from the lungs and deliver it to tissues elsewhere
*To pick up carbon dioxide from other tissues and unload it in the lungs]]> 2017-03-28 10:24:54 UTC https://padlet.com/20294941/1ws20xb7ra9d/wish/163066605 20294941 https://padlet.com/20294941/1ws20xb7ra9d/wish/163067102 White blood cells are also known as leukocytes. They can be divided into granulocytes and agranulocytes. The former have cytoplasms that contain organelles that appear as coloured granules through light microscopy, hence their name. Granulocytes consist of neutrophils, eosinophils and basophils. In contrast, agranulocytes do not contain granules. They consist of lymphocytes and monocytes.

Functions
*Secrete vasoconstrictors which constrict blood vessels, causing vascular spasms in broken blood vessels
*Form temporary platelet plugs to stop bleeding
*Secrete procoagulants to promote blood clotting
*Dissolve blood clots when they are no longer needed
*Digest and destroy bacteria 
*Secrete growth factors to maintain the linings of blood vessels]]> 2017-03-28 10:30:26 UTC https://padlet.com/20294941/1ws20xb7ra9d/wish/163067751
