The Lymphatic System
Tonsils and Adenoids:Help protect you from infection by trapping germs coming in through your mouth and nose.
Lymph Nodes: Found in clusters in neck, armpit, and groin, house leukocytes where they filter blood.
Lymphatic Vessels: Carry lymph (clear, watery fluid with proteins, salts, glucose, etc) located in neck and groin
Thymus: Store leukocytes, house T cells (that destroy foreign antigens).
Spleen: in the upper left quadrant, protects the body by clearing out worn out red blood cells and other foreign bodies
Peyer’s Patches:lymphoid follicles in the small intestine
Appendix: The lining of the appendix is filled with lymphatic tissue, which produces antibodies.
Bone Marrow: store leukocytes, house mature B cells (that seek out antigens and signal to the T cells to kill)
You are working the second shift in the emergency room at a small community hospital. You do not mind working there on Wednesday nights as it is usually pretty quiet. Tonight though, the waiting room is packed and they just keep coming.
You have seen 16 patients, and they all have complained of the same symptoms: severe headache, severe vomiting, diarrhea, and abdominal cramps. The patients range in age from 5 to 36 and the only things they have in common is that they were all at the same amusement park earlier today and they all state that the symptoms came on very suddenly. You are afraid you might have an epidemic on your hands.
The emergency physician notifies the health department, and they ask him if diagnostic tests for Salmonella have been done. He instructs you to obtain a routine urine specimen and stool specimen from each of the patients. Once you have obtained the stool specimens, he tells you to test them each for occult blood. He tells you to take all precautions because he is not sure what disease this is and it might be contagious.
