Ingestion-The act of eating.

4. IMMUNE SYSTEM
The Digestive System
works with the Immune
System by digesting
medicinal foods and
drinks to aid the
Immune System in
fighting off diseases and
infections.
CIRCULATORY SYSTEM
The Digestive System
works with the
Circulatory System by
absorbing the nutrients
from food and delivers
it throughout the body
in blood cells.
5. The nutrients that the Digestive System makes is
necessary for other body systems to maintain
homeostasis. The blood in the Circulatory
System absorbs the products of digestion. The
blood carries the nutrients to all the other
systems providing them with materials that
contain energy.
