Where does the efferent arteriole of the juxtamedullary nephron carry blood to?

The efferent arterioles form from a convergence of the capillaries of the glomerulus, and carry blood away from the glomerulus that has already been filtered. They play an important role in maintaining the glomerular filtration rate despite fluctuations in blood pressure.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
