Anatomy is a staple science topic on Jeopardy!, with nearly 1,500 clues spanning the show's full history and 10 Final Jeopardy appearances. Three dominant category names (ANATOMY, THE HUMAN BODY, and THE BODY HUMAN) account for 84% of all clues, making this one of the most focused topics on the show.
The topic centers on organ identification, bone names, and body system functions. The liver dominates with 30+ clues as the most-tested answer. The core study set is compact: just 15 answers account for the majority of clues, and all are body parts or organs that contestants encounter repeatedly.
Clue patterns by value: Wrong rates climb from ~10% at $100/$200 to ~34% at $2000. Low-value clues ask "What organ does X?" with clear functional descriptions. High-value clues use Latin/Greek terminology, reference specific anatomical structures (islets of Langerhans, dura mater), or ask for less-common body parts.
Study strategy: The most productive approach is to learn the "signature fact" for each major organ; the single association that drives 80% of its clues. The liver = largest internal organ. The femur = longest bone. The pancreas = insulin. The diaphragm = breathing muscle. Once you know these core associations, you'll recognize the vast majority of anatomy clues regardless of how they're worded.
Key stumpers: The dura mater (75% wrong), the pharynx (67%), the mitral valve (60%), the humerus (60%), and the pituitary (42%) are the answers that consistently defeat contestants.

The liver is Jeopardy!'s single most-tested anatomy answer, appearing in every era of the show. It is the body's largest internal organ (the skin is the largest organ overall, a distinction the show tests). The liver produces bile (stored in the gallbladder), detoxifies the blood, stores vitamins, and produces cholesterol. Anything "hepatic" refers to the liver (hepatitis = liver inflammation). The French word "foie" (as in foie gras) also triggers this answer.
The liver sits just below the diaphragm on the right side of the abdomen. It is reddish-brown, weighs about 3 pounds, and receives blood through the hepatic artery. Cirrhosis is the chronic liver disease most often referenced.
The brain is the body's control center, weighing about 3 pounds in adults. Clues reference the cerebrum (largest part, responsible for thought), the cerebellum (coordination and balance), the medulla oblongata (basic life functions like breathing), and the brain stem. The brain uses about 20% of the body's oxygen despite being only 2% of body weight.
The heart has four chambers: two atria (upper) and two ventricles (lower). The left ventricle pumps oxygenated blood to the body; the right ventricle pumps deoxygenated blood to the lungs. The septum divides the heart. Cardiac = relating to the heart. The pericardium is the sac surrounding it. The mitral valve (between left atrium and ventricle) is a separate stumper answer.

The lungs are the organs of respiration. The right lung has three lobes; the left lung has two (to accommodate the heart). Air enters through the trachea, passes through bronchi, and reaches the alveoli, tiny air sacs where gas exchange occurs. Pulmonary = relating to the lungs. The pleura is the membrane surrounding them.
Almost every pancreas clue mentions insulin. The pancreas produces insulin (from beta cells in the islets of Langerhans) to regulate blood sugar, and also produces glucagon and digestive enzymes. Its name comes from Greek meaning "all flesh." The duodenum (first part of the small intestine) wraps around it.
The ear has three sections: outer, middle, and inner. The middle ear contains the three smallest bones in the body (ossicles): the hammer (malleus), anvil (incus), and stirrup (stapes); the stapes is the single smallest bone. The inner ear contains the cochlea (hearing) and semicircular canals (balance/equilibrium). The eardrum (tympanic membrane) separates outer from middle ear.
The large dome-shaped muscle that separates the chest cavity from the abdominal cavity. It contracts during inhalation to draw air into the lungs. Hiccups are involuntary spasms of the diaphragm. This is the ultimate anatomy gimme, contestants have never missed it.
13 clues · 58% correct, CONSISTENT STUMPER (42% wrong)
The "master gland" of the endocrine system, located at the base of the brain. It produces growth hormone, thyroid-stimulating hormone, and controls other endocrine glands. About the size of a pea. Despite 13 appearances, contestants miss it over 40% of the time.
The windpipe: the tube connecting the larynx to the bronchi, carrying air to the lungs. Made of C-shaped cartilage rings. A tracheotomy is an emergency incision into the trachea. Clues often describe it as the "windpipe" and ask for the medical term.
The tongue is covered in papillae (which contain taste buds). It's the strongest muscle relative to its size. Taste zones (sweet, salty, sour, bitter) were once taught as distinct areas but this is now considered oversimplified. The frenulum connects the tongue to the floor of the mouth.
The voice box: contains the vocal cords and sits between the pharynx and trachea. The Adam's apple is the visible protrusion of the larynx (thyroid cartilage). Laryngitis = inflammation of the larynx.
The body's largest artery, carrying oxygenated blood from the left ventricle of the heart to the rest of the body. It arches up from the heart (the aortic arch) then descends through the torso.
The kidneys filter blood and produce urine. Each contains about a million nephrons (the filtering units). The adrenal glands sit atop the kidneys. Renal = relating to the kidneys. Dialysis replaces kidney function.

The transparent front covering of the eye, responsible for most of the eye's focusing power. It has no blood vessels (receives oxygen from tears and aqueous humor). Corneal transplants are among the most common transplant surgeries. Surging in recent seasons.
About 20 feet long in adults: much longer than the large intestine (5 feet) despite the name. Three sections: duodenum (first, shortest), jejunum (middle), and ileum (last, longest). Most nutrient absorption happens here. Villi increase surface area.
The thighbone: the longest AND strongest bone in the human body. Connects to the pelvis at the hip joint (a ball-and-socket joint with the acetabulum). In an average adult male, it's about 19 inches long. Clues often contrast it with the stapes (smallest bone, in the ear).
The shinbone: the larger of the two lower leg bones (the other is the fibula). It's the second-longest bone after the femur and bears most of the body's weight in the lower leg.
The jawbone: the largest and strongest bone in the face, and the only movable bone in the skull. Contains the lower teeth.

The breastbone: a flat bone in the center of the chest connecting the ribs via cartilage. The xiphoid process is its lower tip.
5 clues · varies
One of two forearm bones (the other is the radius). The ulna is on the pinky side; the radius is on the thumb side. The "funny bone" sensation comes from the ulnar nerve near the elbow.
5 clues · 40% correct, STUMPER (60% wrong)
The upper arm bone, connecting shoulder to elbow. Despite the pun potential ("humorous"), contestants frequently miss this. It articulates with the scapula (shoulder blade) at the shoulder and with the radius and ulna at the elbow.
The Aorta, largest artery (from left ventricle). The jugular veins (7 clues, 50% wrong), carry blood from the head back to the heart. Capillaries (9 clues), smallest blood vessels where gas exchange occurs; connect arteries to veins. The mitral valve (5 clues, 60% wrong), between left atrium and left ventricle; named for its resemblance to a bishop's mitre.
The Esophagus (8 clues), muscular tube from pharynx to stomach; uses peristalsis. The Gallbladder (7 clues), stores bile produced by the liver. The Epiglottis (6 clues, 40% wrong), flap that covers the trachea during swallowing to prevent food from entering the airway.
The Retina (7 clues, 100% correct), light-sensitive layer at the back of the eye containing rods (dim light) and cones (color). The Achilles tendon (8 clues), connects the calf muscle to the heel bone; named after the Greek hero whose heel was his only vulnerable spot. The dura mater (5 clues, 75% wrong); the tough outermost membrane covering the brain and spinal cord; name means "tough mother" in Latin.
The Thyroid (6 clues), butterfly-shaped gland in the neck; regulates metabolism. The Pituitary, master gland (see Organs section). Insulin (8 clues), hormone from the pancreas that regulates blood sugar; its absence causes diabetes.
Muscles (13 clues); the body has over 600 skeletal muscles. The gluteus maximus is the largest. Cartilage (6 clues), flexible connective tissue; found in ears, nose, joints. Sharks have skeletons made entirely of cartilage. The Achilles tendon, strongest tendon; connects calf to calcaneus (heel bone).
The Skin (5 clues), the body's largest organ overall (not largest internal organ, that's the liver). The epidermis is the outer layer; the dermis is below it. The Epidermis (5 clues), outermost skin layer; "epi-" means "upon" or "over."
