Activity 2: Pumonary, Systemic, And Coronary Circulations-Tracing the Path of Blood Through the Heart
The heart functions as a single or double pump?
The right side serves what circuit?
Describe how the pulmonary circuit carries blood.
Carries carbon dioxide-rich blood from the right chambers of the heart to the lungs to exchange CO2 for oxygen, and then to bring back the blood to the left side of the heart.
What is the general function of the pulmonary circuit?
The left side serves what circuit?
Describe how the systemic circuit carries blood.
Carries oxygen-rich blood from the left side of the heart through the body tissues and back to the right side of the heart.
Describe the flow of oxygen-rich and oxygen-poor blood through the heart and connecting blood vessels in 9 steps.
1. Right atrium receives oxygen-poor blood from the body via the superior and inferior vena cava
2. Oxygen-poor blood then flows from the right atrium to the right ventricle through the tricuspid valve.
3. From the right ventricle, oxygen-poor blood then flows through the pulmonary valve into the pulmonary trunk.
4. The pulmonary trunk splits into left and right pulmonary arteries, which carry oxygen-poor blood to the lungs, where carbon dioxide is exchanged for oxygen.
5. Oxygen-rich blood then returns to the heart via four pulmonary veins.
6. Oxygen-rich blood enters the left atrium via four pulmonary veins.
7. From the left atrium, oxygen-rich blood flows through the mitral valve to the left ventricle.
8. From the left ventricle, oxygen-rich blood flows through the aortic valve to the aorta.
9. Oxygen-rich blood is delivered to the body tissues by the systemic arteries.
