| Question | Answer |
| Which side of the heart deals with oxygenated blood? | The left hand side of the heart is oxygenated, the right is deoxygenated. |
| What is the structure of the atria? | - Thin walled - elastic(stretches when blood is collected) -Thin muscular wall only needs to pump blood short distance to ventricle |
| What is the structure of the ventricle? | - Much thicker muscular wall because it has to pump blood a long distance, either to the lungs or the rest of the body |
| What is the difference in structure of the right and left ventricle? | - The right ventricle only has to pump blood to the lungs which is a short distance so it has a thinner muscular wall than the left ventricle - The left ventricle has a much thicker muscular wall so it can create enough pressure to pump blood to the rest of the body |
| What are the valves between the atria and ventricles called? | - The valve on the right hand side is called the tricuspid valve and the one on the left is the bicuspid valve |
| What are the roles of the ventricles and veins? | - The ventricles pump blood away from the heart and into the arteries. - The veins pump blood into the heart and into the atria |
| Describe the vessels connected to the left hand side of the heart | - Aorta connected to the LV pumps O blood to the body - Pulmonary vein connected to the LA brings O blood from the lungs |
| Describe the vessels connected to the right hand side of the heart | - Vena cava connected to the RA brings dO blood from body. - Pulmonary artery connected to RV takes dO blood to lungs |
| What is the name of the blood vessel that supplies the heart muscle with oxygenated blood? | The coronary arteries supply the heart with oxygenated blood, they branch off of the aorta into two main arteries covering all of the heart. |
| What are the periods of contraction and relaxation called? | Systole- contraction diastole- relaxation |
