Oxygenated blood flows from the lungs to the
pulmonary veins to the left atrium of the heart,
through the left ventricle, and out the aortic
valve to the aorta, an artery which is also the
bodys largest blood vessel.

4
  • Unoxygenated blood flows from both the superior
    vena cava and the inferior vena cava into the
    right atrium, through the atrioventricular valve
    to the right ventricle and through the pulmonary
    valve to the pulmonary arteries where it is
    headed for the lungs to pick up some oxygen.

Pulmonary Circulation
  • The process of blood going from the heart to the
    lungs and back.

Systemic Circulation
  • The process of blood going from the heart to the
    rest of the body and back.

6
Capillaries
  • One of the most important parts of the
    circulatory system, these tiny blood vessels
    deliver nutrients and oxygen to the cells while
    getting rid of waste products such as carbon
    dioxide.

Alveoli
  • These are tiny air sacs in the lungs where oxygen
    exchange takes place.

7
Things that can go wrong with the heart
  • Congenital heart defects defects that are
    present at birth which involve abnormal or
    incomplete development of the heart
  • Arrhythmia Irregularities in the hearts rhythm
  • Coronary heart disease caused by
    atherosclerosis (fat, calcium, and dead cells are
    deposited in the walls of the coronary arteries),
    this is the most common type of heart disorder in
    adults.
  • Hypertension when a persons blood pressure is
    significantly higher than normalsymptoms include
    headache, nosebleed, dizziness and
    lightheadedness
  • Stroke this occurs when the blood supply to the
    brain is cut off

8
Four steps to maintaining a healthy heart
  • 1. Getting plenty of exercise
  • 2. Eating a nutritious diet
  • 3. Maintaining a healthy weight
  • 4. Getting regular medical checkups
