Question

Головний мозок становить приблизно 2% від загальної маси тіла , потребуючи при цьому 20% крові тіла. Обчисліть приблизну масу свого головного мозку та кількість крові, необхідну для його кровопостачання? Мой вес 54 кг распишите понятно пж.

Answer 1

Ответ:

головний мозок займає приблизно:

54:100=0,54•2=1,08кг

у тілі людина +- 5 літрів крові.

отже, кількість крові, необхідної дляроботи мозку:

5:100•20=1 літра.

Объяснение:

Answer 2

Calculation of Brain Mass and Blood Supply

To calculate the approximate mass of your brain and the amount of blood required for its blood supply, we can use the given information that the brain constitutes about 2% of the total body mass and requires 20% of the body's blood supply.

Given: - Total body weight: 54 kg

Calculation of Brain Mass:

To calculate the mass of your brain, we can use the percentage of body mass that the brain constitutes.

Step 1: Calculate the brain mass as a percentage of the total body mass: - Brain mass = (2/100) * Total body weight

Step 2: Substitute the given value of the total body weight: - Brain mass = (2/100) * 54 kg

Step 3: Calculate the brain mass: - Brain mass = 1.08 kg

Therefore, the approximate mass of your brain is 1.08 kg.

Calculation of Blood Supply:

To calculate the amount of blood required for the brain's blood supply, we can use the percentage of blood supply that the brain requires.

Step 1: Calculate the blood supply required for the brain as a percentage of the total blood supply: - Blood supply for the brain = (20/100) * Total blood volume

Step 2: Substitute the given value of the total body weight: - Blood supply for the brain = (20/100) * 54 kg

Step 3: Calculate the blood supply for the brain: - Blood supply for the brain = 10.8 kg

Therefore, the approximate amount of blood required for the blood supply of your brain is 10.8 kg.

Please note that these calculations are approximate and may vary from person to person.
