Pharynx: the membrane-lined cavity behind the nose and mouth, connecting them to the esophagus. Esophagus: the part of the alimentary canal that connects the throat to the stomach; the gullet. In humans and other vertebrates it is a muscular tube lined with mucous membrane. Stomach: internal organ in which the first part of digestion occurs, being a pear-shaped enlargement of the alimentary canal linking the esophagus to the small intestine. Small Intestine: the part of the intestine that runs between the stomach and the large intestine; the duodenum, jejunum, and ileum collectively. Large Intestine: the cecum, colon, and rectum collectively Appendix: a tube-shaped sac attached to and opening into the lower end of the large intestine in humans and some other mammals. Rectum: the final section of the large intestine, terminating at the anus Pancreas: a large gland behind the stomach that secretes digestive enzymes into the duodenum. Embedded in the pancreas are the islets of Langerhans, which secrete into the blood the hormones insulin and glucagon. Liver: a large lobed glandular organ in the abdomen of vertebrates, involved in many metabolic processes. Kidney: each of a pair of organs in the abdominal cavity excreting urine. Ureter: the duct by which urine passes from the kidney to the bladder or cloaca Bladder: a membranous sac in humans and other animals, in which urine is collected for excretion. Urethra: the duct by which urine is conveyed out of the body from the bladder, and which in male vertebrates also conveys semen. Larynx: the hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals; the voice box. Trachea: a large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs; the windpipe. Bronchus: any of the major air passages of the lungs that diverge from the windpipe. Bronchiole: any of the minute branches into which a bronchus divides. Alveolar Sac: the small air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place. Pituitary Gland: the major endocrine gland. a pea-sized body attached to the base of the brain, the pituitary is important in controlling growth and development and the functioning of the other endocrine glands. Adrenal Gland: situated above the kidneys. Each consists of a core region secreting epinephrine and norepinephrine, and an outer region secreting corticosteroids. Thyroid Gland: a large ductless gland in the neck that secretes hormones regulating growth and development through the rate of metabolism.
