Answer:
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.
The right answer is D (less responsive to antigens)
It is proven that, after puberty, thymus activity (an organ that is included in the lymphatic system, producing T cells that pick up antigens) decreases and that in adult and aged people the thymus has no role. Work done in humans indicate that in fact the cellularity begins to decline from birth in favor of lymphocyte perivascular spaces and connective and adipose tissue, which leads to a decrease in the capture of antigens.
So as you see it’s going up on the x axis
