Quizplus · Accepted Answer

Hemoglobin is the protein in red blood cells that binds to oxygen and transports it throughout the body. Myoglobin is found in muscle tissue and binds oxygen to facilitate muscle function, but it is not involved in blood transport. Carbon dioxide and water are also transported in the blood, but they are typically carried in different ways than oxygen, such as being dissolved in plasma or bound to hemoglobin.
