Question

the human heart
use the anatomical terms in the box below to label and color the diagram.
draw arrows to indicate the direction of blood flow.
parts of the heart
left atrium
left ventricle
inferior vena cava
pulmonary vein
pulmonary vein
superior vena cava
ght atrium
right ventricle
pulmonary artery

Explanation:

Each label is matched to the corresponding heart structure based on standard human heart anatomy, with blood flow direction described as the path of deoxygenated and oxygenated blood through the heart.

1. Top left tube (superior): Superior vena cava (carries deoxygenated blood from upper body to right atrium)
2. Small tubes below superior vena cava: Pulmonary veins (carry oxygenated blood from lungs to left atrium)
3. Large curved tube below those: Pulmonary artery (carries deoxygenated blood from right ventricle to lungs)
4. Bottom left tube: Inferior vena cava (carries deoxygenated blood from lower body to right atrium)
5. Lower left heart chamber: Right ventricle (pumps deoxygenated blood to lungs)
6. Top right large tube: Aorta (carries oxygenated blood from left ventricle to the body)
7. Small tubes on the right side: Pulmonary veins (carry oxygenated blood from lungs to left atrium)
8. Upper right heart chamber: Left atrium (receives oxygenated blood from lungs)
9. Lower right heart chamber: Left ventricle (pumps oxygenated blood to the body)
10. Upper left heart chamber: Right atrium (receives deoxygenated blood from body)

Blood flow direction:

• Deoxygenated blood: Superior/inferior vena cava → Right atrium → Right ventricle → Pulmonary artery → Lungs
• Oxygenated blood: Pulmonary veins → Left atrium → Left ventricle → Aorta → Body

Answer:

Labeling (from top-left to bottom-right, matching the diagram's numbered boxes):

1. Superior vena cava
2. Pulmonary vein
3. Pulmonary artery
4. Inferior vena cava
5. Right ventricle
6. Aorta
7. Pulmonary vein
8. Left atrium
9. Left ventricle
10. Right atrium

Blood flow arrows follow the path: Superior/inferior vena cava → Right atrium → Right ventricle → Pulmonary artery → Lungs → Pulmonary veins → Left atrium → Left ventricle → Aorta → Body
