Answer:

Approximately 25 arteries would branch off

Step-by-step explanation:

Aorta has a diameter of 2 cm, so area is pi x 1^2 = 3.142

In case of the artery, pi x 0.2^2 = 0.126

So dividing total area of aorta by total area of one artery, we get 3.142/0.126 = 25.021

Hence, about 25 arteries will be needed to carry the amount of blood that flows in the aorta vessel.
