ANSWER: The correct answer is CAPILLARIES
EXPLANATION: Arteries are the muscular wall tube that carries oxygenated blood from the heart to other part of the body. The arteries extend outward from the heart, and form capillaries.
The capillaries are hairlike thinnest blood vessels, that helps to join the arteries and ventricles together. The blood in the arteries extends to the capillaries of the organs where the blood is supplied, and then moves out to from the organ via the ventricles.
The capillary starts from the part of the arteries that are very thin.
Oooh really a interesting thing if we were made of prokaryotic cells ....
as we know, prokaryotic cells lacks nucleus and membrane bound organelles.
The majority of prokaryotic <span><span><span><span>DNA </span></span></span></span><span>is found in a central region of the cell called the </span>nucleoid. Then we are not able to do activities like now we do bcz if we lacks a true nucleus which contains our all genetic info: we are just like prokaryotic organisms....
