Detailed explanation-1: -Brain mass contributes minimally to total body mass (∼2%) (14, 37) and thus only has a small effect on the scaling of body weight to height. On the other hand, brain has a high mass-specific metabolic rate (∼240 kcal·kg−1·day−1) and accounts for ∼20% of energy expended at rest (7).
Detailed explanation-2: -The adult human brain is about 2% of total body weight. Men listen with the left side of the brain and women use both sides of the brain. The average human brain weighs about 3 pounds.
Detailed explanation-3: -The average human brain weighs about three pounds, representing about two percent of our body weight. The human heart pumps blood to the entire body, but actually pumps about 20 percent of its total blood output to the brain.
Detailed explanation-4: -The adult human brain weighs about 3 pounds (1, 300-1, 400 g). The adult human brain is about 2% of the total body weight.
Detailed explanation-5: -The adult human brain weighs approximately about 1, 300-1, 400 g. 3. Therefore, the adult human brain is about 2% of the total body weight.
