What is one interesting point that you didn’t know about before reading the information about your chosen body parts?

One interesting point that often surprises people when learning about the human brain is its energy consumption. The brain, despite being only about 2% of a person’s body weight, uses approximately 20% of the body's total energy. This high energy requirement is due to the brain's complex functions, including processing information, regulating bodily functions, and maintaining homeostasis. Even when resting, the brain remains highly active, reflecting the immense resources it needs for neurotransmission, neuronal firing, and other metabolic processes. This highlights the brain's critical role in overall body function and emphasizes the importance of cognitive health and nutrition for optimal brain performance.
