Describe the ways that obesity increases the risk of heart disease. Include in your discussion the following terms: fat pads, lungs, and blood vessels
Obesity increases the risk of heart disease, partly because excess fat pads crowd the heart muscle and the lungs within the body cavity. These fat pads encumber the heart as it beats, requiring it to work harder to deliver oxygen and nutrients to the rest of the body. Also, the lungs cannot expand fully, thus limiting the oxygen intake of each breath and causing the heart to work even harder. Furthermore, because each extra pound of fat tissue demands to be fed by way of miles of capillaries, the heart must work extra hard in obese people to pump blood through a network of blood vessels that is vastly larger than that of a thin person. Even a healthy heart is strained by excess fat. When a diseased heart finds itself in this bind, a sudden increase in workload may be more than it can handle.
