The Mammalian Heart

  • The heart is labelled as if it was in the chest so what is your left on a diagram is actually the right hand side and vice versa
  • The right side of the heart receives deoxygenated blood from the body and pumps it to the lungs
  • The left side of the heart receives oxygenated blood from the lungs and pumps it to the body
  • Blood is pumped towards the heart in veins and away from the heart in arteries
  • The two sides of the heart are separated by a muscle wall called the septum
  • The heart is made of muscle tissue which are supplied with blood by the coronary arteries
