QUIZ QUESTIONS LISTED AT END OF REVIEW

Questions related to the Bodily Organs and Systems will test your knowledge of structures and functions within the ten human organ systems that are essential to life. You may also be tested on vocabulary terms related to your understanding of anatomy. You must understand these vital body systems when caring for patient’s co-morbidities.

Please note that the ATI TEAS will only cover basic knowledge of bodily organs and systems. More in-depth knowledge will be covered in our Anatomy and Physiology Series.

Let’s get started on understanding how the bodily organs and systems are important on the ATI TEAS.




 

THE LYMPHATIC SYSTEM

The lymphatic system has three functions

  1. Returns excess fluid back into the blood which helps maintain fluid balance.
  2. Absorbs fats from the digestive track and deposits them in the blood stream.
  3. Defends the body against pathogens.

The lymph nodes are small glands found mainly in the thorax and abdomen. These glands help prevent disease by filtering out bacteria in the lymph, a watery fluid formed from interstitial, or tissue, fluid.

Other organs vital to the lymphatic system are the spleen, tonsils, and thymus.

  • The spleen filters bacteria in the blood.
  • Tonsils, located at the base of the tongue, functions as a filter of interstitial fluid.
  • The thymus gland is pertinent for immune responses.
