Question

Объем циркулирующей крови в организме составляет 1/13 от массы тела в сердечно- сосудистой системе находится 80% циркулирующей крови. посчитайте обьем крови в сердечно сосудистой системе человека массой 78 кг

Answer 1

78 /13  = 6 кг- всего крови
6 * 0,8 = 4,8 кг крови в с/с системе

Answer 2

Calculating the Volume of Blood in the Cardiovascular System

To calculate the volume of blood in the cardiovascular system of a person weighing 78 kg, we can use the information provided. According to the statement, the volume of circulating blood in the body is 1/13 of the body weight, and 80% of the circulating blood is located in the cardiovascular system.

Let's break down the calculation step by step:

1. Calculate the volume of circulating blood in the body: - The volume of circulating blood is 1/13 of the body weight. - For a person weighing 78 kg, the volume of circulating blood would be (1/13) * 78 kg.

2. Calculate the volume of blood in the cardiovascular system: - 80% of the circulating blood is located in the cardiovascular system. - Multiply the volume of circulating blood by 80% to find the volume of blood in the cardiovascular system.

Let's perform the calculation:

1. Calculate the volume of circulating blood in the body: - (1/13) * 78 kg = 6 kg

2. Calculate the volume of blood in the cardiovascular system: - 80% of 6 kg = 0.8 * 6 kg = 4.8 kg

Therefore, the volume of blood in the cardiovascular system of a person weighing 78 kg is approximately 4.8 kg.

Please note that the volume of blood in the cardiovascular system can also be expressed in liters. To convert from kilograms to liters, we need to know the density of blood, which is approximately 1.06 g/ml. However, since the question does not provide this information, we cannot convert the volume to liters.
