Torie Soriano Physiology Lab Report The Effects of Exercise on the Cardiovascular System Introduction Exercise has a major impact on the cardiovascular system and its efficiency in the human body. There are many concepts which need to be examined to understand exercise and the cardiovascular system‚ such as systolic and diastolic blood pressure‚ cardiac output‚ total peripheral resistance‚ and physiological pathways. According to the European Journal of Cardiovascular Prevention and Rehabilitation

common cardiomyopathies are extrinsic. This is because the most common cause of a cardiomyopathy is ischemia. Ischemic cardiomyopathy is basically weakness in the muscle of the heart due to inadequate oxygen delivery to the myocardium. Coronary artery disease is the most common cause for this lack of oxygen‚ but anemia and sleep apnea have

Heart Rate Anticipatory Response: Anticipatory heart rate is the rate that the heart reaches before the start of exercise. Your heart rate usually picks up as a result of the anticipatory heart-rate response‚ this happens before exercise. When thinking about exercising before actually starting‚ the nerves that release the chemicals that adjust your heart rate increase the heart rate. The body expects exercise and therefore prepares for the activity‚ increasing the amount of oxygen being delivered

and get oxygen from our lungs. The heart rate is measured in beats/ minute and a “beat” is when the lower chambers are (two ventricles) contract. This process pushes the blood into high pressure arteries to the low pressure veins. Heart rate is most easily measured by counting the pulse of the blood in artery vein in your neck. Motivation/Purpose: It is good to measure heart rate constantly. People are constantly developing heart conditions that aren’t known until it’s too late. Asthma is constantly

Coronary Heart Disease Coronary heart disease‚ also called coronary artery disease or ischemic heart disease‚ it characterized by an inadequate supply of oxygen-rich blood to the heart muscle (myocardium) because of narrowing or blocking of a coronary artery by fatty plaques. If the oxygen depletion is extreme‚ the effect may be a myocardial infarction (heart attack); if the deprivation is insufficient to cause infarction (death of a section of heart muscle)‚ the effect may be angina pectoris

flow is increased. 4. Describe the relationship between vessel length and blood flow. The longer a vessel is the slower blood flow is going to be. The shorter a vessel is the faster blood flow is going to be. 5. In a partially blocked coronary artery‚ what happens to vessel radius and what effects does this have on blood flow? What effect would this have on the heart? The blood vessel would constrict and cause your blood pressure to increase. This would put great strain on your heart and eventually

cardiovascular disease that can be changed are tobacco‚ overweight and obesity‚ high blood pressure‚ unhealthy blood cholesterol‚ physical inactivity‚ and diabetes. Smoking harms the cardiovascular system in numerous ways. It damages the lining of arteries. It reduces the level of good cholesterol and it raises the levels of bad cholesterol. Tobacco also increases your heart rate and blood pressure. High blood pressure‚ or hypertension‚ is a risk factor for other forms of CVD‚ including heart attacks
