Case Study 1 A&P II Age-Related Changes that Occur in the Cardiovascular System As we age‚ certain changes in the heart are inevitable. Even in the absence of disease‚ the wall of the heart thickens‚ heart rate slows‚ maximum heart rate declines‚ and the heart doesn’t pump as efficiently as it once did. Health problems‚ such as hypertension‚ coronary disease‚ congestive heart failure‚ and myocardial infraction are more common in the elderly and aggravate age- related degenerative change in the

Investigative Quest The purpose of this experiment was to find out how music affects the female human heart rate. Hypothesis My hypothesis is that female resting heart rate will increase as the music tempo increases. If the tempo is slower the heart rate will stay at resting heart rate or decrease. Variables The variables used in this experiment were: • The tempo of the music. • The subject’s heart rate. • The subject’s age. Controls The controls used in this experiment were: • How long the

The Effect of Position on Heart Rate This lab explores the effect of head position on an individual’s heart rate by having a subject move it’s head while simultaneously monitoring the subjects heart rate. There were three successive periods during which the heart rate was monitored that occurred in this order: a resting stage (subject sitting upright)‚ a stage with the head positioned between the knees‚ and a recovery stage (subject returns to upright position). The graph depicts a wide range

The affect of psychological stress on the heart rate. Introduction: The human body is incredible machinery that can adjust to stressful situations and react in a “fight-or flight” manner by temporarily shutting off nonessential‚ at the moment‚ immune and digestive systems. When the body is ready for a challenge‚ heart rate increases‚ blood pressure rises and glucose production intensifies to supply large amounts of energy. These metabolic changes are caused by release of stress hormones (catecholamine

QUESTION: In what ways do gender‚ height‚ weight and practicing sports influence the capacity of human lungs? INTRODUCTION: Breathing is the process of respiration‚ during which air is inhaled into the lungs through the mouth or nose due to muscle contraction‚ and then exhaled due to muscle relaxation. It provides a supply of fresh air to the lungs and removes the building up carbon

The Effects of Exercise on the Body In society exercise is most commonly associated with weight loss; however exercise has many other implications not limited to the physical body‚ but a person ’s mind and lifestyle as well. Beginning an exercise regimen is often referred to as a lifestyle change‚ and that is exactly what exercise can do‚ change a person ’s life. The general assumption that an individual can lose weight through physical activity is true‚ however exercise can also have a positive

Nostril Breathing Versus Normal Breathing After conducting a mini “study” of whether alternate nostril breathing helps people with sleep issues as opposed to normal breathing at bed time‚ it was concluded that‚ yes‚ alternate nostril breathing at bed time does help to relax a person and put them in a more sound sleep than normal breathing. In the personal study conducted‚ three nights were done under normal breathing circumstances and three nights with the alternate nostril breathing technique

Tidal breathing is an automatic and unconscious act. During speech breathing‚ it is a voluntary act in which the speaker controls. Tidal breathing and speech breathing have different inhalation rates which one can solve using the iFraction method. The iFraction method is taking the amount of time it takes to inhale and dividing it by the total respiratory cycle. Tidal Breathing has a person inhaling around 0.45 seconds during a respiratory cycle‚ but speech breathing inhalation takes
