1. Cells
- Definition: Cells are the smallest units of life in our body.
- Function: They perform essential functions that keep us alive.
- Types of Cells: There are many different types of cells, including muscle cells, nerve cells, and blood cells.
2. Tissues
- Definition: Tissues are groups of similar cells that perform a specific function.
- Types of Tissues:
- Muscle Tissue: Helps in movement.
- Nervous Tissue: Sends signals throughout the body.
- Epithelial Tissue: Covers surfaces and lines cavities.
3. Organs
- Definition: Organs are made up of different tissues working together.
- Examples of Organs:
- Heart: Pumps blood throughout the body.
- Lungs: Allow us to breathe and exchange gases.
- Stomach: Aids in digestion.
4. Organ Systems
- Definition: Organ systems are groups of organs that work together to perform complex functions.
- Examples of Organ Systems:
- Circulatory System: Transports blood and nutrients.
- Respiratory System: Responsible for breathing.
- Digestive System: Breaks down food and absorbs nutrients.
The Major Systems of the Human Body
Understanding the major systems of the human body is essential for kids to appreciate how everything works together. Let’s take a closer look at these systems.
