As we all know, blood's primary role is transportation. Blood vessels resemble a system of roadways where things are delivered, and waste is removed. In addition to carbon dioxide and other waste materials being eliminated from the body, blood carries nutrients, hormones, oxygen, and other substances throughout the body. The blood is continually being pumped around the body by the heart.
Vitamins, minerals, carbohydrates, fats, proteins, and other nutrients are transported throughout the body via the blood. Through the small intestine, digested nutrients are absorbed into the blood. Then they are transferred to the cells in the body that need them.
Communication between organs is made possible by the blood's transportation of hormones throughout the body. Hormones aid in the regulation of several bodily functions, such as mood, growth, and development.
The four substances transported by blood are respiratory gases, nutrients, hormones and waste materials.
