Anatomy & Physiology Cardiac #5

Question

Which structure sends blood to the lungs for oxygenation to occur?

Answers

  1. Pulmonary artery
    • Rationale:

      The pulmonary artery is a structure that carries oxygen-poor blood from the right ventricle of the heart to the lungs for oxygenation.

  2. Pulmonary vein
    • Rationale:

      The pulmonary vein is a structure that carries oxygenated blood from the lungs to the left atrium of the cardiac muscle.

  3. Aorta
    • Rationale:

      The aorta is the main artery of the body. It supplies oxygenated blood to the circulatory system from the heart.

  4. Atria
    • Rationale:

      The atria is either of the two upper chambers of the cardiac muscle that receive blood from the veins and force it into the ventricles.

Overview

There are two circulatory pathways that move blood to, through, and from the cardiac muscle.

Explanation

Learning Outcomes

The right side of the heart has the pulmonary circulation pathway which moves blood to the lungs for reoxygenation. The left side of the heart has the systemic circulation which moves oxygenated blood to the rest of the body. The pulmonary artery is responsible for carrying oxygen-poor blood from the heart to the lungs for oxygenation to occur.
