Atourniquet is a band that is placed over a major artery to constrict the flow of blood. would you expect a tourniquet over the radial artery (near the elbow) to increase the blood pressure on the proximal side of the band (closer to the center of the body) or the distal side of the band (closer to the fingers)? why?

Imagine a self-reactive t cell that has not undergone clonal deletion in the thymus (that is to say, it has escaped central tolerance). if it encounters self antigen in the absence of an infection or inflammation, what will happen to this self-reactive t cell? (select two answers) (a) the t cell undergoes clonal expansion. (b) the t cell gains effector functions. (c) the t cell undergoes apoptosis. (d) the t cell becomes activated. (e) the t cell becomes anergic.
