Critical Thinking Questions
- A closed circulatory system is a system in which the blood mixes with the interstitial fluid. Fish have a two-chambered heart. Amphibians and reptiles have a three-chambered heart, but the latter has little mixing of blood. Mammals and birds have a four-chambered heart and double circulation.

- Blood in closed circulatory system is present inside blood vessels and circulates unidirectional from the heart, around the systemic circulatory route, then returns to the heart. It is less controlled and structured than an open circulatory system, but nutrients and waste products are transported more efficiently.
- Blood in closed circulatory system is not enclosed in blood vessels, but is pumped into a hemocoel, which circulates around the organs, then reenters the heart through ostia. It is more structured, controlled, and nutrients and waste products are transported more efficiently.

- Oxygenated blood carried by the right side of the heart is completely separated from the left side carrying deoxygenated blood, which assists in more efficient movement of oxygen around the body and aids in allowing the body to quickly move when needed.
- A four-chambered heart keeps oxygenated and deoxygenated blood separated and has double circulation whereas a three-chambered heart has a single circulation. This assists in more efficient movement of oxygen around the body.
- Oxygenated and deoxygenated blood are kept separate in a four-chambered heart, which assists in more efficient movement of carbon dioxide around the body.
- Oxygenated and deoxygenated blood are kept separate in a four-chambered heart, which assists in more efficient movement of oxygen around the body and aids in allowing the body to move quickly when needed.

- An internal implant sends an electrical impulse through the heart.
- It is an electrical impulse that starts in cardiac muscle cells at the sinoatrial node.
- It is the excitation of cardiac muscle cells at the atrioventricular node followed by the sinoatrial node.
- It starts in the aorta.

The diagram shows the internal anatomy of the heart. How would blood circulation beyond the heart be affected if the pulmonary valve could not open?
- Blood could not reach the rest of the body.
- Blood could not reach the lungs.
- Blood could not return from the lungs.
- Blood could not return from the rest of the body.
The diagram below shows the internal anatomy of the heart. How would blood circulation beyond the heart be affected if the tricuspid valve could not open?
- Blood could not enter the pulmonary veins; therefore, it could not reach the lungs.
- Blood could not enter the pulmonary artery; therefore, it could not reach the heart.
