The organs of the digestive system work together to digest food and absorb nutrients.(the gastrointestinal tract organs and pancreas, liver, gallbladder, salivary glands). The circulatory system is in charge of taking those nutrients and delivering them to our cells.
Healthy grasslands are important habitats for birds and other wildlife, and also places where we farm and ranch. They provide food, cover, space and safe access to water for both wildlife and livestock.
