Arteries are able to withstand the enormous pressure of blood as it is pumped by the heart and to expand and relax between heart beats.
The heart is awesome. it pumps the blood and fills the arteries making them high in blood pressure. --3

Differentiation
The structure of DNA is stable but it can undergo mutation once in a while to provide the raw materials for natural selection to act upon. lol from Kaplan huh?
Different cells are different in structure because of their different functions (e.g. plant cells have cell walls because they don't have bones). Also, cells have different functions because they work together with other cells to create a working system (e.g. the human body)

The structures in the lungs enable the lungs to exchange oxygen for carbon dioxide in the blood. The structure are also designed to help the lung protect themselves from irritants.
Simply because they'e often supplied form a single source - under high pressure, to enable them to circulate right through the hospital. Copper pipes can withstand higher pressures.
It has a flagella that is a tail like structure that propels it.

You can't. Paintnet doesn't support pressure sensitivity. It used to, but it got removed.
Arteries take blood from the heart to the body. Capillaries are tiny blood vessels that enable substance exchange between the blood and the body tissues. Veins carry blood back to the heart.
Gills enable tadpoles to breathe in the water.
The genetic variation enable a particular species to withstand the adversities of Nature by way of selection on the basis of the principle of survival of the fittest.
