Study Notes
- Human blood consists of red and white cells, platelets, and plasma.
- Erythrocyte is another name for a red blood cell.
- Blood clotting is unrelated to immunity, leukocytes, and antibodies.
- Increased erythrocyte levels benefit an athlete by increasing the oxygen-carrying capacity of the blood.
- In the blood, most oxygen is transported bound to hemoglobin inside the red blood cells.
- Leukocytes provide the major defense for our bodies against invading bacteria and viruses.
- The vena cava contains the lowest amount of oxygen.
- The tricuspid valve lies between the right atrium and right ventricle.
- Cardiac output is blood pumped by the left ventricle in 1 minute and can be calculated by Stroke Volume x Heart Rate.
- The pulmonary artery carries deoxygenated blood to the lungs, which is an exception since arteries typically carry oxygenated blood.
- The electrocardiogram (ECG) QRS wave indicates the ventricles are depolarizing while the atria repolarize.
- Cardiovascular Drift is the most likely reason that heart rate continues to climb after 45 minutes of exercise, despite slowing down.
- The relatively clear liquid medium which carries the other cells of blood is called plasma.
- Blood exerts the force measured as systolic blood pressure on the arterial walls during ventricular contraction.
- Pulmonary circulation delivers deoxygenated blood to the lungs, and systemic circulation delivers oxygenated blood to the body.
- Freshly oxygenated blood enters the heart through the left atrium.
