We recently followed a drop of blood through the heart. This week, we would like to follow a drop of blood through the body. But first, we would like to review quickly how a drop of blood flows through the heart.
- superior and inferior vena cava
- right atrium
- tricuspid valve
- right ventricle
- pulmonary valve
- pulmonary artery
- pulmonary vein
- left atrium
- mitral valve
- left ventricle
- aortic valve
The left ventricle pumps the strongest to send the blood out of the left ventricle and through the aorta arch which will go to the rest of the body.
At this point, there are a few options for the blood to flow:
- The blood is then pumped through the carotid artery to the brain.
- The blood is also pumped through the auxiliary arteries and into the arms.
- The blood is also pumped through the aorta and into the torso and the legs.
The arteries meet up with the capillaries where oxygen and carbon dioxide are exchanged.
The blood will then travel through the smallest veins called venules which will branch into bigger vessels called veins. These veins now carry deoxygenated blood to the main vein which is called the vena cava. The two branches, superior vena cava and inferior vena cava, carry the blood back to the right atrium.
The cycle now repeats.
