Which human organ weighs about 1.4 kg and 0.85 litres of blood passes through it every minute?

Correct option is A

The correct answer is (a) Brain
· The brain weighs about 1.4 kg in an average adult, and approximately 0.85 liters (850 mL) of blood passes through it every minute. The brain is one of the most vital organs, responsible for regulating all bodily functions, including thought processes, emotions, and motor control.
Information Booster:
· The brain uses about 20% of the body's oxygen supply, even though it constitutes only about 2% of the total body weight.
· It has a high metabolic demand, requiring continuous blood flow to supply oxygen and nutrients.
· The brain is divided into two hemispheres and consists of different regions such as the cerebrum, cerebellum, and brainstem, each serving unique functions.
Additional Information:
· Kidneys: Weigh around 150 grams each, and they filter approximately 1.2 liters of blood per minute to remove waste products and excess fluids.
· Heart: Weighs about 250-350 grams and pumps about 5 liters of blood per minute throughout the body.
· Lungs: Weigh about 1.3 kg (both together), and they are responsible for exchanging oxygen and carbon dioxide during breathing, but the amount of blood flowing through them is much higher, approximately 5 liters per minute.
