70
A tip to help you pull blood from the lateral tail vein in a rat is to use heat/warmth on tail prior to venipuncture. Explain the reasoning of using heat.
the heat will cause the vein to vasodilate, making the blood flow stronger
71
Athymic mice are missing what organ? The missing organ is responsible for providing what type of cell to the body? What is an advantage for researchers to use athymic mice?
They are missing their thymus, which produces T cells. Because they are missing T cells, they aren't able to mount a good immune response to pathogens. The allows the pathogen to be studied without an immune interference.
