Human Digestive System :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) Nutrition

Human Endocrine System :Human 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
