Heart and Circulatory System

How does the blood remove waste from the body?

A Answers (1)

  • The vascular system (or circulatory system) functions as an important component of other body systems. Examples include:
    • Respiratory system -- As blood flows through the capillaries in the lungs, carbon dioxide is given up and oxygen is picked up. The carbon dioxide is expelled from the body through the lungs, and the oxygen is taken to the body tissues by the blood.
    • Digestive system -- As food is digested, blood flows through the intestinal capillaries and picks up nutrients, such as glucose (sugar), vitamins, and minerals. These nutrients are delivered to the body tissues by the blood.
    • Kidneys and urinary system -- Waste materials from the body tissues are filtered out from the blood as it flows through the kidneys. The waste material then leaves the body in the form of urine.
    • Temperature control -- Regulation of the body's temperature is assisted by the flow of blood among the different parts of the body. Heat is produced by the body's tissues as they go through the processes of breaking down nutrients for energy, making new tissue, and giving up waste matter.
