Final answer:
The three types of oxygen delivery systems are vessels transporting oxygenated blood, vessels transporting deoxygenated blood, and vessels involved in gas exchange. Different organisms have evolved different proteins, such as hemoglobin, myoglobin, and hemerythrin, for oxygen transport. In the fetus, there are three major shunts that redirect blood flow away from the nonfunctional lungs.
Step-by-step explanation:
The three types of oxygen delivery systems are:
- Vessels transporting oxygenated blood
- Vessels transporting deoxygenated blood
- Vessels involved in gas exchange
In mammals, birds, reptiles, fish, and some insects, hemoglobin is used to transport oxygen from the lungs to the cells, while myoglobin temporarily stores oxygen in the tissues. Invertebrates, such as marine worms, use hemerythrin for oxygen transport.
During fetal life, the circulatory system of the fetus has three major shunts which divert blood to different parts of the body, bypassing the nonfunctional lungs. These shunts close shortly after birth, when the newborn starts breathing independently.
