Your former best friend sneezed on you a couple of days ago, and now you are in the clutches of a Rhinovirus, which has given you a nasty head cold. Your virus-infected cells are sending out warnings to the yet un-infected cells in the form of proteins called ____________.
Interferons
You were frying eggs in your new non-stick pan this morning. You picked up your phone to answer a text, and totally burned your eggs. The non stick coating became so overheated that it released toxic PTFE fumes. You inhaled it, and it caused a cancerous mutation in a cell deep in your lungs. So you had lung cancer by the time you reached class. Fortunately for you, your _____________ cells did their job, attacked the cancerous cells by noon, and you were cancer free by lunch time.
Natural Killer cells
Babesiosis is a disease in which the Babesia organism attaches to the red blood cell. This results in anemia, because the ____________, which filters the blood, identifies the infected cells and removes them from circulation.
Spleen
Little Mahmood had a surgery to have his __________ removed, because they were chronically infected and swollen.
Tonsils
