What is an organ?
An organ is a part of your body that has a special job. Your body has many organs that work together to keep you alive and healthy.
Major organs and their jobs
- Heart – pumps blood to the rest of your body.
- Lungs – help you breathe in oxygen and breathe out carbon dioxide.
- Brain – controls your thoughts, movements, and feelings.
- Stomach – starts digestion by breaking down food.
- Liver – helps digest fats and cleans the blood.
- Kidneys – clean your blood and make urine.
- Skin – your largest organ, protects you and helps you stay warm or cool.
- Intestines – absorb nutrients from food in the small intestine and water in the large intestine.
Step by step learning
- Learn what each organ does with simple words.
- Group organs into body systems like the circulatory system and digestive system.
- Think about how organs work together in everyday actions like running or eating.
How do these organs work together
Different parts of your body join forces as systems. Here are a few examples:
- Circulatory system (heart and blood): moves blood to all body parts.
- Respiratory system (lungs and airways): brings oxygen in and carbon dioxide out.
- Digestive system (stomach, intestines, liver, etc.): breaks down food and absorbs nutrients.
- Nervous system (brain and nerves): sends signals so you can think and move.
Fun facts
- Your heart beats about 100,000 times a day.
- Your lungs move about 20,000 breaths a day.
Remember: organs are in charge of different jobs, and they all help your body work together to keep you healthy and growing.
