No, blood does not travel through the alveoli. There is however a dense blood capillary network surrounding the alveoli.
A small portion is carried in the blood plasma and the remainder is transported by combining with hemoglobin.
Most nutrients enter the blood through the small intestines.
As blood glucose. But it is stored as glycogen in the liver.
Proteins are transported through the blood stream.
through aortic arches that function as many small hearts
yes through your veins :)
Through the blood stream.
Glucose is transported through the blood
Heat is transferred through the blood

nitrogenous waste is carried through the blood. the waste passes into the nephrons (kidney cells) inside the nephrons the blood passes through "the loop of henly" in which the waste is pulled out of the blood and send to the bladder to be concentrated as urea

plasma
Blood cells and platelets are suspended in blood plasma (mostly water) and moved through the body in blood vessels (arteries, veins & capillaries). The blood is forced through the blood vessels by the heart.
Through the bloodstream, dissolved in the blood and bound to haemoglobin,
Oxygen in the blood is transported by hemoglobin.
