Practice Question

A nurse is assisting with teaching a class about oxygen transport in the cardiopulmonary system. Which of the following cells transports oxygen in the blood? 

Answer Choices:

Correct Answer:

Hemoglobin

Rationale:

💎 Hemoglobin is a specialized iron-containing protein found within red blood cells (erythrocytes) that is responsible for binding and transporting oxygen from the lungs to body tissues.

💎 Each hemoglobin molecule can carry up to four oxygen molecules, forming oxyhemoglobin when oxygenated in the pulmonary capillaries.

💎 As blood circulates, hemoglobin releases oxygen in tissues where oxygen tension is low and binds carbon dioxide for return to the lungs.

💎 This oxygen transport system is essential for maintaining cellular respiration and energy production.

💎 Conditions such as anemia, hemorrhage, or carbon monoxide poisoning reduce hemoglobin’s ability to carry oxygen, leading to hypoxia.
