Which three materials primarily compose the human body?

The human body is primarily composed of moisture, along with combustible and non-combustible materials. Moisture is a fundamental component, as water constitutes a significant portion of the body, facilitating various biological functions.

Combustible materials, such as organic compounds found in cells and tissues, represent the organic makeup that can burn and release energy. Non-combustible materials include minerals that contribute to the body’s structural integrity, such as calcium in bones.

Understanding the composition of the body in these categories provides insight into how the body interacts with the environment and its components during processes like cremation, where the composition significantly influences the cremation process and the resulting ashes.

Other options focus on different aspects; for instance, while proteins, carbohydrates, and fats do contribute significantly to body composition, the emphasis on moisture, combustibility, and non-combustibility gives a broader perspective on the materials and their behaviors, particularly in the context of cremation.
