Hi so i have a question about how much blood in the human body. online it said 1- 2 gallons, but is that everything or just red blood cells only?

The basics: Blood is composed of fluid (serum) and various cellular elements like red cells, white cells, platelets and a variety of other factors. Blood means everything. The red cell fraction makes up 45-52% of total blood volume in males, 37-48% in females.

5 liters: 5 liters or 1 and 1/3 gallons In an average healthy adult, the volume of blood is about one-eleventh of the body weight. Most sources state the volume of blood in an average human adult, who is between 150 to 160 pounds, as between 4.7 and 5 liters, although the more recent sources state the volume of blood in an average adult as 4.7 liters.
