circuits

• pulmonary circuit: blood vessels that carry blood to and from the lungs
• systemic circuit: the blood vessels that carry blood to and from all body tissues
• right and left atrium receive blood returning from systemic and pulmonary circuits
• right and left ventricle pump blood through the circuits
• Left side of heart is systemic circuit pump and the right side is the pulmonary circuit pump
• • Pulmonary circuit is a low pressure circulation and is served by the right side.
  • Left side has much more work than the right side and is shown because it's thicker and the left side is circular in comparison to the right
  • left side has so much more power
• Coronary circulation: process through which the heart receives blood

  • myocardium is too thick for diffusion
  • get it from the aorta
  • shortest circuit in the body
  • delivered when heart is relaxed
