Circulatory System Notes
Pulmonary Circulation: Lungs, oxygen into blood, carbon dioxide out
Systemic Circulation: Moves blood to body (not to heart or lungs)
Coronary or Cardiac Circulation: Moves blood to the heart muscle
• Chamber: one of the four sections of the heart
• Valve- keeps the blood flowing in one direction in heart and veins
• Pacemaker- controls heart rate
• Atria (atrium)- the top two chambers of the heart that receive blood from lungs or body
• Ventricles- lower chambers that pump blood to the body or lungs
• Arteries- Blood vessels that carry blood away from the heart
• Veins- Blood vessels that carry blood to the heart
• Capillaries- microscopic blood vessels that connect arteries and veins
• Coronary arteries- blood vessels that carry blood to the heart muscle
• Blood pressure- force of blood- highest in arteries
• Hypertension- high blood pressure
