Which body systems interact to absorb nutrients? Explain.
The digestive system and the circulatory system interact to absorb nutrients in the body.
The digestive system is responsible for breaking down food into smaller molecules that can be absorbed by the body. This process begins in the mouth with the mechanical and chemical breakdown of food, then continues in the stomach and small intestine where further digestion and absorption occur.
Once the nutrients have been broken down into smaller molecules, they are absorbed into the bloodstream through the walls of the small intestine. This is where the circulatory system comes into play. The bloodstream carries these nutrients to cells throughout the body where they can be used for energy, growth, and repair.
Overall, the digestive system processes and breaks down food into smaller molecules, while the circulatory system transports these nutrients to cells throughout the body for use. The two systems work together to ensure that the body receives the necessary nutrients for proper functioning.
