- Regulates blood pH (acid-base balance)
- Maintains osmotic balance by regulating the amount of water within the bloodstream, along with the oncotic pressure of plasma proteins
- Helps regulate body temperature using blood-heating and cooling mechanisms
- Defends against infections using leukocytes and antibodies
- Promotes blood coagulation (clotting) using coagulation factors
- Transports hormones and other metabolites
