Step-by-step solution for: Human Circulatory System - Worksheet | Distance Learning ...
Here is the solution to both Q.4 and Q.5 based on human circulatory system anatomy and physiology.
---
Q.4. Write T or True if the statement is true; write F or False if the statement is false.
✔ 1. In red blood cells, oxygen molecules bind to a protein called hemoglobin.
→ True (T)
*Explanation:* Hemoglobin is the iron-containing protein in red blood cells that binds to oxygen in the lungs and transports it to tissues throughout the body.
✔ 2. Arteries usually carry oxygenated blood and veins usually carry deoxygenated blood.
→ True (T)
*Explanation:* With the exception of the pulmonary artery (which carries deoxygenated blood to the lungs) and pulmonary veins (which carry oxygenated blood from the lungs), arteries carry oxygen-rich blood away from the heart, and veins return oxygen-poor blood to the heart.
✔ 3. About 55% of blood is made up of plasma, a clear pale-yellow fluid.
→ True (T)
*Explanation:* Blood is composed of about 55% plasma (the liquid component containing water, proteins, ions, etc.) and 45% formed elements (red blood cells, white blood cells, platelets).
✘ 4. The systemic circulation carries deoxygenated blood from the heart to the lungs.
→ False (F)
*Explanation:* Systemic circulation carries oxygenated blood from the left ventricle of the heart to the body tissues, and returns deoxygenated blood back to the right atrium. The pulmonary circulation carries deoxygenated blood from the heart to the lungs.
✘ 5. The pulmonary circulation carries oxygenated blood to the body.
→ False (F)
*Explanation:* Pulmonary circulation carries deoxygenated blood from the right ventricle to the lungs for oxygenation, then returns oxygenated blood to the left atrium. It does not deliver blood to the body — that’s the job of systemic circulation.

Q.5. Label the chambers of the human heart on the diagram below.
*(Note: Since I can’t see the actual image, I will assume standard labeling based on typical heart diagrams with arrows pointing to the four chambers.)*
In a standard anterior view of the heart:
- The top right chamber (receives deoxygenated blood from the body via superior/inferior vena cava) → Right Atrium
- The bottom right chamber (pumps deoxygenated blood to the lungs via pulmonary artery) → Right Ventricle
- The top left chamber (receives oxygenated blood from the lungs via pulmonary veins) → Left Atrium
- The bottom left chamber (pumps oxygenated blood to the body via aorta) → Left Ventricle
➡️ So, assuming the arrows point as follows (from top to bottom, left to right):
Left side labels (from top to bottom):
- Top arrow → Right Atrium
- Bottom arrow → Right Ventricle
Right side labels (from top to bottom):
- Top arrow → Left Atrium
- Bottom arrow → Left Ventricle
*(If your diagram has different arrow placements, adjust accordingly — but this is the most common layout.)*

✔ Final Answers:
Q.4:
1. T
2. T
3. T
4. F
5. F
Q.5:
*(Assuming standard diagram orientation)*
- Left-top box: Right Atrium
- Left-bottom box: Right Ventricle
- Right-top box: Left Atrium
- Right-bottom box: Left Ventricle
Let me know if you’d like a visual sketch or further clarification!
