B) It distributes oxygenated blood to the pulmonic circulation.
C) It arises within the left ventricle.
D) It is color coded blue to indicate its degree of oxygen saturation.

Accepted Answer

The aorta arises within the left ventricle, making option C the correct answer. Option A is incorrect because the aorta distributes oxygenated blood, not unoxygenated blood. Option B is incorrect because the aorta distributes oxygenated blood to the systemic circulation, not the pulmonic circulation. Option D is incorrect because the aorta is color coded red to indicate its oxygen saturation.
