1. Heart
2. Brain
3. An organ? The only think I could think is that it might be a gland if the question was production of an enzyme.

1)blood circulation is done by the circulatory system(arteries and veins) and the heart is acting like the pump(for blood).

2) Brain and its nervous system(consisting of neurons..these neurons send the signals for every sensation the body feels)

3)digestion for food-
 Stomach secretes digestive enzymes like pepsin and hydrchloric acid through smooth muscular contortions called segmentation, before sending partially-digested food (called chyme) to the small intestines.
