The volume of circulating blood in the body is 1/13 of the body weight; the cardiovascular system contains 80% of the circulating blood. calculate the volume of blood in the cardiovascular system of a person weighing 78 kg

First, you need to find the total weight of the blood that circulates in the human body.

To do this, multiply the indicated body weight by the given part, namely 1/13.

We get:

78 * 1/13 = 78/13 = 6 liters.

We know that the human cardiovascular system contains 80% of the circulating blood.

Since this weight is 6 kg, it means that this system circulates:

6 * 80% = 6 * 0.8 = 4.8 kg of blood.

Answer: There are 4.8 kg of blood in the cardiovascular system.
