What are some functions of blood?Multiple select question.transport of gasessecretion of hormonesdefense against pathogensblood clotting (coagulation)

The functions of blood include:

1. Transport of gases: Blood carries oxygen from the lungs to the rest of the body, and it carries carbon dioxide from the body's cells back to the lungs to be exhaled.

2. Defense against pathogens: White blood cells in the blood help to fight off infections and diseases by attacking and destroying pathogens.

3. Blood clotting (coagulation): When a blood vessel is damaged, platelets in the blood stick together to form a clot. This prevents excessive bleeding and allows the wound to heal.

The secretion of hormones is not a function of blood. Hormones are produced by glands in the endocrine system and then released into the bloodstream, where they are transported to the cells and organs they affect. However, the blood itself does not secrete hormones.
