Answer:

A chemical change results in a different state of matter, and a physical change results in a new substance being formed.

Explanation:

Chemical change:

Chemical changes occur when the bonds are formed or broken between atoms or molecules. This results in formation of completely different state of matter having different properties. They are irreversible.

Example of chemical change : burning of wood

When wood is burnt, ash is formed and produces energy in the form of light and heat. This ash cannot be converted back into wood.

Physical change:

But physical changes doesn't lead to formation of new substance rather they lead to the change in the shape or state of the object. They can be either reversible or irreversible.

Example of physics change : chopping of wood

When the wood is chopped its properties remains same. Only the shape and the structure of the wood will be altered.

Alenkasestr [34]

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.
