Correct Answer
A. HemoglobinExplanation
Hemoglobin is the correct answer because it is a substance found in red blood cells that carries oxygen and gives blood its color. Hemoglobin binds to oxygen in the lungs and releases it to the body's tissues, ensuring the delivery of oxygen throughout the body. It also gives blood its red color. Hormone, H2O, CO2, and platelets are not substances that carry oxygen or give blood its color.Rate this question:

- D.
Right ventricle
Correct Answer
B. ArteryExplanation
An artery is a blood vessel that carries blood away from the heart. It is responsible for delivering oxygen-rich blood to various parts of the body. Arteries have thick, elastic walls that help withstand the high pressure generated by the heart's pumping action. The blood flowing through arteries is typically bright red in color, indicating its oxygenation. Unlike veins, which carry blood back to the heart, arteries carry oxygenated blood from the heart to nourish tissues and organs throughout the body.Rate this question:

A blood vessel that returns blood to the heart
- A.
Artery
- B.
Capillary
- C.
Atrium
- D.
Vein
Correct Answer
D. VeinExplanation
A vein is a blood vessel that carries deoxygenated blood back to the heart. Unlike arteries, veins have thinner walls and contain valves to prevent blood from flowing backward. The deoxygenated blood from various parts of the body is collected by veins and transported back to the heart, where it will be pumped to the lungs for oxygenation. Veins are an essential part of the circulatory system and play a crucial role in maintaining blood flow and oxygenation throughout the body.Rate this question:
