What Is the Yellowish Fluid That Carries Disease-Fighting Cells?
CNA Exam Knowledge
Direct Answer
The yellowish fluid that carries disease-fighting cells is called Lymph.
Understanding the Lymphatic System
Lymph is a clear-to-yellowish fluid that circulates throughout the lymphatic system. Its primary job is to transport lymphocytes (white blood cells) which fight infection and disease.
Think of the lymphatic system as the body's drainage and defense network. It drains excess fluid from tissues and filters out bacteria and viruses at lymph nodes (like the ones in your neck).
Key Terms to Know
- Lymphocytes: Disease-fighting white blood cells found in lymph.
- Lymph Nodes: Small bean-shaped structures that filter the lymph fluid.
- Edema: Swelling caused when excess fluid is not drained properly by the lymphatic system.
