Since I can't view images directly, I’ll help you label the structures of the heart based on a typical anatomical diagram like the one you described. This appears to be a
frontal (anterior) view of the human heart, showing major chambers, vessels, valves, and other key features.
Below is a list of common structures labeled in such diagrams, along with their positions. You can match these to the lines pointing to each structure in your image:
---
Structures of the Heart – Labeled from Top to Bottom (Typical Diagram)
1.
Superior Vena Cava – Large vein returning deoxygenated blood from the upper body into the right atrium.
2.
Inferior Vena Cava – Large vein returning deoxygenated blood from the lower body into the right atrium.
3.
Pulmonary Arteries – Carry deoxygenated blood from the right ventricle to the lungs (usually shown as two branches).
4.
Right Atrium – Upper right chamber receiving blood from the vena cavae.
5.
Right Ventricle – Lower right chamber pumping blood to the lungs via pulmonary arteries.
6.
Tricuspid Valve – Between right atrium and right ventricle; prevents backflow.
7.
Pulmonary Veins – Carry oxygenated blood from the lungs to the left atrium (typically 4 veins).
8.
Left Atrium – Upper left chamber receiving oxygenated blood from the pulmonary veins.
9.
Left Ventricle – Lower left chamber pumping oxygenated blood to the body.
10.
Mitral (Bicuspid) Valve – Between left atrium and left ventricle; prevents backflow.
11.
Aorta – Largest artery carrying oxygenated blood from the left ventricle to the body.
12.
Pulmonary Trunk – Main vessel branching into pulmonary arteries; carries blood from right ventricle.
13.
Chordae Tendineae – String-like fibers connecting the valve flaps to papillary muscles.
14.
Papillary Muscles – Muscular projections in the ventricles that anchor chordae tendineae.
15.
Septum – Wall dividing the left and right sides of the heart (interatrial and interventricular).
16.
Aortic Valve – Between left ventricle and aorta; prevents backflow.
17.
Pulmonary Valve – Between right ventricle and pulmonary trunk; prevents backflow.
18.
Coronary Arteries – Branches from the aorta that supply blood to the heart muscle itself.
19.
Coronary Sinus – Collects deoxygenated blood from the heart muscle and drains into the right atrium.

How to Label:
- Start from the
top of the diagram: look for the large vessels coming into the heart.
- Identify the
right side (de-oxygenated blood) vs.
left side (oxygenated blood).
- The
aorta usually arises from the top-left of the left ventricle.
- The
pulmonary arteries come from the right ventricle and go toward the lungs.
- Valves are located between chambers and vessels (e.g., tricuspid, mitral, pulmonary, aortic).

If you can describe where each line points (e.g., “the topmost vessel on the left,” or “the valve between the left atrium and left ventricle”), I can give you exact labels for your specific diagram.
But using the above list, you should be able to correctly label all structures in a standard heart diagram. Let me know if you'd like a visual guide or mnemonic!
Parent Tip: Review the logic above to help your child master the concept of structure of heart worksheet.
