Within the mediastinum‚ bordered laterally by the lungs‚ posterio0rly by the vertebral column‚ anteriorly by the sternum. 2) Distinguish between the visceral pericardium and the parietal pericardium. Visceral is a membrane that covers the surface of the heart. Parietal is a membrane that forms the outter wall of the peritoneal cavity 3) Describe the layers of the heart wall.

the systolic pressure in the forearm and calf using the same methods as Exercise 3. In Exercise 5‚ we measured systolic pressure while the volunteer was standing and lying down. In Exercise 6‚ we measured the distance between the heart and where the veins in the hands collapse to determine venous pressure. In Exercise 7‚ we measured the forearm circumference as the volunteer held their arm above their head with increasing cuff pressure. Results: The average systolic and diastolic pressures for the

caused by the natural aging process‚ where the once elastic walls of the arteries harden and become less flexible. Smoking‚ diabetes‚ obesity and genetics also contribute to heart disease. Stroke - A stroke is a brain attack. We have arteries and veins running through the brain. These vessels can either become occluded due to plaques which can break free from the walls of arteries and block the vessel. Thrombosis The heart is surrounded by three major coronary arteries that supply it with blood

capillaries and veins are major blood vessels. Arterioles are the smaller versions of arteries and they feed the capillaries. Capillaries are where exchange between blood and cells take places. The capillaries gives the cells nutrients‚ hormones and dissolved gases. The capillaries flush antigens to lymphoid and aid movement of proteins. Excessive capillary pressure causes edema which is excessive fluid. Venules receives the deoxygenated blood from the capillaries and transport it to the veins that brings

to fight diseases. Lastly it removes waste products. What helps to control the flow of the blood around the body are the vessels and muscles made up of the circulatory system. This process is called circulation. The heart‚ arteries‚ capillaries and veins are the main part of this system. As blood begins to circulate‚ it leaves the heart from the left ventricle and goes into the aorta. The aorta is the largest artery in the body. The blood leaving the aorta is full of oxygen. This is important for
