Final answer:
Jeff has 5.23 liters of blood, with cells making up approximately 45% of the mass and the remainder being plasma, which is primarily water. Blood plasma contains various dissolved substances essential for bodily functions. The average adult has about 4.7 to 5.7 liters of blood, which is about 8 percent of an adult's body weight.
Step-by-step explanation:
Jeff's body contains about 5.23 liters of blood with a density of 1060 kg/m3. Blood consists of cells, which make up approximately 45.0% of the blood's mass, and plasma, which makes up the remaining 55%. The density provided is more common to use in physics, but here it helps us understand the mass of blood Jeff has.
Blood plasma is mainly water, constituting about 92% of its content, and includes a variety of dissolved substances such as proteins, glucose, ions, hormones, and gases. Considering the mass percentage of cells, we know that more than half of Jeff's blood is plasma. This plasma plays a crucial role in transporting nutrients, waste, and other solutes throughout the body.
The average adult body contains between 4.7 and 5.7 liters of blood, with adult males averaging slightly more than females. Blood volume can constitute approximately 8 percent of an adult's body weight, and it is a key component in maintaining homeostasis, including the regulation of pH and temperature.
