Which of the following is NOT a part of the human circulatory system?a...

Explanation:

Heart:
- The heart is a vital organ in the human circulatory system that pumps blood throughout the body.

Blood vessels:
- Blood vessels are the channels through which blood is transported around the body. They include arteries, veins, and capillaries.

Lungs:
- The lungs are part of the respiratory system, not the circulatory system. However, they play a crucial role in oxygenating the blood that is then circulated by the heart.

Kidneys:
- The kidneys are part of the excretory system and are responsible for filtering waste products from the blood to form urine. They are not directly involved in the transportation of blood throughout the body.

Therefore, the correct answer is option 'D) Kidneys' as they are not a part of the human circulatory system.
