  1. Cardiovascular System Heart Functions

  2. Functions of the Heart • Keeps O2 poor blood separate from O2 rich blood. • Keeps the blood flowing in one direction – blood flows away from and then back to the heart in each circuit. • Creates blood pressure, which moves the blood through the circuits. • Regulates the blood supply based on the current needs of the body.

  3. Functions of the Blood Vessels • Transport blood and its contents. • Carry out exchange of gases in the pulmonary capillaries and exchange of gases plus nutrients for waste at the systemic capillaries. • Regulate blood pressure. • Direct blood flow to those systemic tissues that most require it at the moment.
