- The heart
- blood flows into top two chambers called atria.
- blood entering left atrium is from pulmonary vein
- oxygenated blood from the lungs
- blood goes through the aorta artery to the rest of the body
- atria contract and force the blood to the ventricles
- contract and force blood out of the heart
- valves close to stop the back flow of blood and make sure it is flowing in the right direction
- aorta carries oxygenated blood away from the heart around the body
- atria contract and force the blood to the ventricles
- blood goes through the aorta artery to the rest of the body
- oxygenated blood from the lungs
- blood entering right atrium is from the vena cava
- deoxygenated blood from the body
- forced through pulmonary artery to the lungs
- brings deoxygenated blood from the body the heart
- deoxygenated blood from the body
- blood entering left atrium is from pulmonary vein
- problems with blood flow through heart.
- coronary heart disease
- coronary arteries become narrow
- where the heart gets oxygenated blood from
- caused by build up of fatty materials on the lining of vessels.
- coronary arteries become narrow
- coronary heart disease
- blood flows into top two chambers called atria.
- organ with four chambers
- walls are made of muscular tissues.
- wall is ticker on the left side o the heart as it has to pump more blood all around the body

- helping the heart
- your resting heart rate is controlled by a group of cells in the right atrium wall.
- these cells act as a pacemaker - tell the heart when to pump blood
- pacemaker that doesn't work properly causes an irregular heartbeat.
- artificial pacemaker can be used to keep the heart beating regularly
