Difficulty: EasyHuman Anatomy and Body Systems

Match each human organ with its primary physiological function in the body.

  • HeartPumping blood continuously throughout the circulatory system
  • LungsExchanging oxygen and carbon dioxide gases with the atmosphere
  • KidneysFiltering metabolic waste and excess fluid from blood to form urine
  • StomachSecreting acid and enzymes to chemically break down food boluses

Answer

Heart matches with pumping blood throughout the circulatory system; Lungs match with exchanging oxygen and carbon dioxide gases; Kidneys match with filtering metabolic waste to form urine; Stomach matches with secreting acid and enzymes to chemically break down food.
Each organ directly corresponds to its characteristic physiological process: the muscular heart contracts to pump blood, the alveoli within the lungs facilitate oxygen and carbon dioxide diffusion, the renal nephrons in the kidneys extract waste to yield urine, and the gastric mucosa of the stomach produces digestive secretions.

Step-by-Step Solution

1
Identify the primary role of each organ within its organ system.
Heart belongs to the circulatory system (blood propulsion), lungs to the respiratory system (gas exchange), kidneys to the urinary/excretory system (blood filtration), and stomach to the digestive system (chemical/mechanical breakdown).
Each listed organ serves a distinct core function in human physiology.
2
Pair each organ to its corresponding functional description.
All four pairings are uniquely and unambiguously mapped.
Matching structural components to their physiological actions confirms fundamental knowledge of major human body systems.
