Structure you need to know

  • You are expected to know all the names of the structures of the heart mentioned in the slide before
  • You do not need to know each of the specific valve names

What do valves in the heart do?

  • The valves keep blood moving through the heart in the right direction
  • Valves prevent backflow of blood

Real hearts don’t exactly look like the diagram!

  • Let’s label real heart diagrams
  • Be sure to label: front, back, left side, right side, aorta, vena cava, pulmonary artery, pulmonary vein, right and left atria, right and left ventricles, Coronary Sinus, the septum, and valves
  • Use your other diagram to help you

Heart Dissection on Wednesday and Thursday

  • For the dissection, you will be working in groups of 3
  • Form groups of 3 when labelling this picture
  • The group you work with today, will be the group you work with during the dissection

Key information to help identify structures

  • the front of the heart has a blood vessel called the coronary sinus
  • Front view: the right side will be squishier since it is less muscular than the left
  • Deoxygenated or oxygenated sides/structures
