All of the above systems work together to fight foreign invaders that may cause infection or disease.
- The integumentary system (skin, hair, nails) provides a physical barrier against pathogens.
- The immune system actively identifies and destroys pathogens.
- The lymphatic system transports lymph, which contains immune cells, and helps in the removal of toxins and waste.
Each system plays a crucial role in protecting the body from infections and diseases.
