What are the two basic structures that make up the lymphatic system?
Lymph vessels and lymph nodes. Lymph vessels carry the lymph, and lymph nodes clean the toxins from it.
The lymphatic system's function is to transport lymph, a clear, whitish fluid that does not contain red blood cells, but does contain sugars, proteins, salts, fats, and lymphocytes—a type of white blood cell—from the body's extremities, where it separates from blood, back to rejoin arteries in the neck.
Lymph is transported by lymph vessels, which are similar to veins and arteries in general anatomy. They have thin walls and valves that stop lymph from flowing backward; when a fluid flows in the wrong direction, it pushes the valves closed in front of it.
More waste is carried by it, including waste from dying cells that release toxins or other waste from infections; these are eliminated by kidney-shaped, but much smaller, structures called lymph nodes, which are mostly found in the groin, neck, and axillae (armpits); your tonsils are particularly large lymph nodes.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
