The image provided is a labeled diagram of the human heart with a key at the bottom. Since the user did not specify a particular question (e.g., "What is number 10?"), the task is to interpret the diagram and match the numbered parts to their correct names based on the provided legend.
Here is the step-by-step breakdown of the labels shown in the diagram:
1.
Number 1 points to the large vein entering the top of the right atrium. The key identifies this as the
Superior vena cava.
2.
Number 2 points to the large vessel carrying blood away from the right ventricle towards the lungs. The key identifies this as the
Pulmonary artery.
3.
Number 3 points to the vessels bringing blood back from the lungs to the left atrium. The key identifies these as the
Pulmonary vein.
4.
Number 4 points to the valve between the left atrium and left ventricle. The key identifies this as the
Mitral valve.
5.
Number 5 points to the valve at the exit of the left ventricle leading to the aorta. The key identifies this as the
Aortic valve.
6.
Number 6 points to the thick-walled lower chamber on the left side. The key identifies this as the
Left ventricle.
7.
Number 7 points to the lower chamber on the right side. The key identifies this as the
Right ventricle.
8.
Number 8 points to the upper chamber on the left side. The key identifies this as the
Left atrium.
9.
Number 9 points to the upper chamber on the right side. The key identifies this as the
Right atrium.
10.
Number 10 points to the large artery carrying oxygenated blood to the body. The key identifies this as the
Aorta.
11.
Number 11 points to the valve between the right atrium and right ventricle (specifically the pulmonary semilunar valve in this diagram's context, though the key says Pulmonary valve). The key identifies this as the
Pulmonary valve.
12.
Number 12 points to the valve between the right atrium and right ventricle. The key identifies this as the
Tricuspid valve.
13.
Number 13 points to the large vein entering the bottom of the right atrium. The key identifies this as the
Inferior vena cava.
Final Answer:
1. Superior vena cava
2. Pulmonary artery
3. Pulmonary vein
4. Mitral valve
5. Aortic valve
6. Left ventricle
7. Right ventricle
8. Left atrium
9. Right atrium
10. Aorta
11. Pulmonary valve
12. Tricuspid valve
13. Inferior vena cava
