How does water in plasma contribute to the overall function of blood?

• Water makes up 90% of plasma and acts as a solvent, carrying dissolved substances such as nutrients, hormones, and waste products.

• Water in plasma primarily serves as a source of energy for blood cells.

How does hemoglobin bind to oxygen?

• Hemoglobin can bind up to two molecules of oxygen due to its two heme groups.

• Hemoglobin binds to oxygen through its amino acid chains, not heme groups.

• Hemoglobin can bind an unlimited number of oxygen molecules because of its flexible structure.

What is the primary function of blood in humans and other animals?

• To deliver necessary substances like nutrients and oxygen to cells and transport metabolic waste products away from those cells.

• To regulate body temperature and maintain homeostasis.

• To produce hormones that control various bodily functions.
