List, in order, all the vessels blood must flow through to get from the abdominal aorta into the kidney and back to the inferior vena cava.

Kidneys are the important organ of excretion. Human kidneys are bean shaped located below the rib cage. Different vessels are involved in the transportation of blood from the abdominal aorta  and back to the inferior vena cava.

The order of blood vessels are:

The blood enters in the aorta and and moves to the renal artery. Then the blood moves to the interlobar artery via segmental artery. The blood enters in the afferent glomerular arteriole from the arcuate artery and cortical radiate artery. Glomerulus receive the blood from the afferent glomerular arteriole. Then, the blood moves to the efferent glomerular arteriole. The blood then enters in the cortical radiate vein via peritubular capillaries and vasa recta. The blood moves back to the inferior vena cava from the arcuate vein, interlobar vein and renal vein.

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
