Question

Suppose an anesthetic enters a capillary below the skin and continues its journey through structures of the circulatory system. ? Along what sequence of structures does the anesthetic continue its journey? A. Vein, artery, heart, venule, arteriole b. Arteriole, venule, heart, artery, vein c. Venule, arteriole, heart, vein, artery d. Venule, vein, heart, artery, arteriole

Answer 1

D, Venule, vein, heart, artery, arteriole

Step-by-step explanation:

The squence of blood circulation from the heart, begins with the aorta (artery),(distribution,This push the blood into the smaller branches from it callled the arterioles. The lattter are for microscopic distribution into the capillary beds,through the capillaries to reach the cells and the tissues.

The capillaries( containing the anesthetic) lead back, to empty into the venules,which are (smaller) subdivision of larger veins. The veins through the superior and inferior vena-cava empty the anesthetic to the heart.

This is pumped by the heart, through the aorta,and distributed through the arteriole to reach the tissues and cells.
