- D.
Produce vitamin D to help bones absorb calcium
Correct Answer
D. Produce vitamin D to help bones absorb calciumExplanation
The skin works with the skeletal system by producing vitamin D, which helps the bones absorb calcium. Calcium is essential for maintaining strong and healthy bones. When exposed to sunlight, the skin produces vitamin D, which is then transported to the liver and kidneys to be converted into its active form. This active form of vitamin D helps the intestines absorb calcium from the diet, ensuring that an adequate amount of calcium is available for bone health. Therefore, the skin's role in producing vitamin D is crucial for the skeletal system's ability to absorb and utilize calcium effectively.Rate this question:

Which of the following components of blood help the body carry oxygen and carbon dioxide?
- A.
Plasma
- B.
Red blood cells
- C.
Platelets
- D.
White blood cells
Correct Answer
B. Red blood cellsExplanation
Red blood cells, also known as erythrocytes, are responsible for carrying oxygen from the lungs to the body's tissues and transporting carbon dioxide from the tissues back to the lungs to be exhaled. They contain a protein called hemoglobin, which binds to oxygen in the lungs and releases it in the tissues. This process is essential for the body's cellular respiration and maintaining proper oxygen levels in the body. Plasma, platelets, and white blood cells have different functions in the blood, but they do not directly participate in the transport of oxygen and carbon dioxide.Rate this question:

Which of these is responsible for transporting oxygen poor blood from the body back into the heart?
- A.
Arteries
- B.
Bronchial tubes
- C.
Capillaries
- D.
Veins
Correct Answer
D. VeinsExplanation
Veins are responsible for transporting oxygen poor blood from the body back into the heart. Unlike arteries, which carry oxygen-rich blood away from the heart, veins have valves that help prevent the backflow of blood and aid in the return of blood to the heart. Veins transport deoxygenated blood from the body's organs and tissues back to the heart, where it is then pumped to the lungs to pick up oxygen before being circulated throughout the body again.Rate this question:

Which blood vessel is oxygen rich and carries blood away from the heart?
- A.
Veins
- B.
Arteries
- C.
Capillaries
- D.
Red blood cells
Correct Answer
B. ArteriesExplanation
Arteries are the blood vessels that carry oxygen-rich blood away from the heart. They have thick and elastic walls that allow them to withstand the high pressure generated by the heart's pumping action. Oxygenated blood is pumped from the heart into the arteries, which then branch out into smaller vessels called arterioles and eventually into capillaries, where oxygen and nutrients are exchanged with surrounding tissues. Veins, on the other hand, carry oxygen-depleted blood back to the heart.Rate this question:
