Anatomy & Physiology Cardiac #3

Question

Which structure of the heart receives oxygen-poor blood from the upper body?

Answers

  1. Aorta
    • Rationale:

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

  2. Pulmonary artery
    • Rationale:

      The pulmonary artery carries oxygen-poor blood from the right ventricle to the lungs for oxygenation to occur.

  3. Inferior vena cava
    • Rationale:

      The inferior vena cava, a large vein, carries oxygen-poor blood from the lower body to the heart.

  4. Superior vena cava
    • Rationale:

      The vena cava is a large vein that carries deoxygenated blood from the body to the heart. The superior vena cava supplies blood from the upper body to the heart.

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 superior vena cava is the heart structure that receives oxygen-poor blood from the upper body.
