Summary Internal Body Organs

Heart: A muscular organ located in the chest, slightly left of the midline. It pumps blood throughout the body, delivering oxygen and nutrients to tissues and removing waste products. Lungs: Paired organs situated in the chest cavity, responsible for gas exchange. Oxygen is taken in and carbon dioxide is expelled during breathing. Liver: The largest internal organ, located in the upper right abdomen. It performs a variety of functions, including detoxification, protein synthesis, and the production of biochemicals necessary for digestion. Kidneys: Bean-shaped organs located near the middle of the back, on either side of the spine. They filter waste products from the blood, regulate electrolyte balance, and produce urine. Stomach: A muscular organ located in the upper left abdomen, responsible for breaking down food through mechanical and chemical digestion. Intestines: The digestive tract is divided into the small intestine and the large intestine. The small intestine absorbs nutrients from digested food, while the large intestine absorbs water and forms feces. Brain: The control center of the nervous system, housed within the skull. It coordinates voluntary and involuntary actions and processes sensory information. Pancreas: An organ located behind the stomach, with dual functions in the endocrine and digestive systems. It produces insulin and other hormones, as well as digestive enzymes to break down food. Spleen: A small organ located on the left side of the abdomen, involved in filtering blood and storing blood cells. Gallbladder: A small, pear-shaped organ located beneath the liver, responsible for storing and concentrating bile produced by the liver before releasing it into the small intestine to aid in digestion.
