At a mean follow-up of 8 years, we found consistent. alleviation of pain, restoration of joint stability, mean. arc of motion ranging from 6Â° to 92Â° of flexion, and grip. strength returned to within 90% of the contralateral side.
The heart, the lungs, and the veins and arteries (blood vessels) make up the circulatory system. Working together, they ensure that blood flows through the whole network that makes up the human body (systemic circulation), as well as within the lungs (pulmonary circulation) and the heart (coronary circulation).eins and arteries are known as blood vessels. Arteries carry blood away from the heart and veins carry blood toward the heart. The major blood vessels that branch out of the heart are the aorta, the vena cava, and the pulmonary arteries and pulmonary veins.
The circulatory system is made up of the heart and blood vessels. The heart pumps oxygen-rich blood through vessels called arteries. Veins carry blood from various parts of the body back to the heart. Arteries and veins are connected by tiny capillaries (KAP'ih-laireez). The heart's right side receives dark bluish blood from the superior and inferior vena cava. (The superior vena cava is the large vein that brings blood back from the upper part of the body. The inferior vena cava is the vein that brings blood from the lower body.) The heart's right side pumps this blood to the lungs. There, waste gas (carbon dioxide) is removed and oxygen is picked up. The bright red oxygenated blood returns to the heart's left side.
