Like in the forearm, the arm is drained by the brachial veins (deep veins that accompany the brachial artery) and all its branches. In addition, the basilic and cephalic veins course upwards through the subcutaneous tissue and drain the superficial regions of the arm.
The heart is divided into four chambers that are connected by heart valves. The lower two chambers of the heart are called ventricles. They are separated by a septum into the left ventricle and the right ventricle. The upper two heart chambers are called atria. Atria receive blood returning to the heart from the body and ventricles pump blood from the heart to the body. Due to the force needed to pump blood to the body, ventricles have thicker walls than do atria. The ventricles of the heart function to pump blood to the entire body.
