- Lungs: The lungs are organs that facilitate breathing and oxygenation of the blood.
- Brain: The brain is the control center of the body and regulates various functions such as movement, sensation, and cognition.
- Liver: The liver is an organ that filters blood, stores glycogen, and produces bile.
- Kidneys: The kidneys are organs that filter waste and excess fluids from the blood.
- Stomach: The stomach is an organ that digests food and absorbs nutrients.
Body Systems
The human body is composed of various systems that work together to maintain overall health and function. These systems include:- Nervous System: The nervous system consists of the brain, spinal cord, and nerves that transmit and process information.
- Circulatory System: The circulatory system consists of the heart, blood vessels, and blood that transport oxygen and nutrients to cells.
- Respiratory System: The respiratory system consists of the lungs, trachea, and airways that facilitate breathing and oxygenation of the blood.
- Digestive System: The digestive system consists of the mouth, esophagus, stomach, and intestines that break down and absorb nutrients from food.
- Urinary System: The urinary system consists of the kidneys, ureters, bladder, and urethra that filter waste and excess fluids from the blood.
