human digestive system
Digestion is the breakdown of nutrients to a level that can be used by cells of the body.

Structures

GI tract (mouth, pharynx, esophagus, stomach, small intestine, large intestine)

Accessory (teeth, tongue, salivary glands, liver, gall bladder, pancreas)

endocrine system
The endocrine system consists of ductless glands that produce hormones.

Hypothalamus, pituitary, pineal, thyroid, parathyroid, thymus, adrenal, pancreas, ovary, testes

Hormones are chemical messengers that travel through the blood stream and affect activities throughout the body.

Steroid hormones

Nonsteroid hormones
