- Organ: Group of tissues working together for a specific role (e.g., heart)
- Organ system: Two or more organs working together (e.g., circulatory system)
- Organism: A living being (e.g., human)
Integumentary System
- Composed of skin, nails, hair, glands, and nerves
- Physical barrier protecting the body from bacteria, infection, injury, and sunlight
- Detects sensations like hot and cold
- Skin functions to protect internal organs and regulate body temperature
- Epidermis: Outer layer; produces pigments, protects, and provides water-proof barrier
- Dermis: Middle layer; contains nerves, sweat glands, hair follicles
- Subcutaneous tissue: Innermost layer; contains fat, connective tissues, and blood vessels
Skin
- Largest organ in the body
- Epidermis: Outer layer, produces pigment; protects against immune system and environment.
- Dermis: Contains nerve endings, sweat glands, and hair follicles
