The part of blood that carries digested food (nutrients) throughout the body is the plasma. Plasma is the liquid component of blood and makes up about 55% of total blood volume. It is a pale, yellowish fluid that serves as a transport medium for various substances, including nutrients obtained from the digestion of food in the digestive system.
When you consume food, it undergoes digestion in the gastrointestinal tract, where it is broken down into simpler molecules like glucose, amino acids, and fatty acids. These nutrients are then absorbed into the bloodstream through the walls of the small intestine. Once in the bloodstream, they are carried by the plasma to cells and tissues throughout the body, where they are used for energy, growth, and various physiological processes.
In addition to transporting nutrients, plasma also carries hormones, waste products, electrolytes, and other substances that are vital for maintaining the body’s overall function. It plays a crucial role in distributing the essential components needed for the body’s metabolic and physiological processes.
