Abstract Whens humans exercise, their oxygen supply needs to be increased in order to produce the energy needed to sustain this workload. Humans will use a variety of cardio-respiratory mechanisms in order to supply and meet the oxygen levels the body needs during exercise. In this study we wanted to see how different individuals respond to exercise, specifically how long they can work and how efficiently they work. We predicted that females who exercise will have a higher relative-VO2, higher…

results on its impact to health, life, and the human body. Many studies have been done regarding the effects of repetitive participation in vigorous physical activities and the changes in the human body, especially in respects to the cardiovascular system and the observed changes of myocardial structure and function (Baggish & Wood 2011). But what is the impact of these changes? It is well known that exercise benefits the heart which, as important as it is, is a muscle and thus can be…

and then transports it to each body cell for respiration. In the blood vessels the blood flows in the opposite direction to the water that flows through the lamellae. This flow is called the counter-current system. The amount of oxygen that diffuses into the blood is maximized by this system by maintaining the concentration gradient the whole way through. This is done when the blood that is the most oxygenated meets the most oxygenated water, and the least oxygenated blood meets the water that…

They can affect your urinary tract system and can cause several problems. They can form when minerals crystallize and get stuck together. Symptoms include pain in the back and/or side, pain when urinating, red or brown urine, nausea, urinating in small amounts, and cloudy urine. The treatments…

Cardiovascular Response: When exercising the muscles requires a constant supply of oxygen, it is the hearts job to make sure there is enough oxygen being pumped round the body for the muscles, the heart has to pump harder and faster as more oxygen is required to get round the body to the muscles in use otherwise they will fatigue quicker. If this is repeated regularly, then over time the heart will become stronger as will become more used to the higher demands. At the start of exercise, the…

Clear! The physics behind the electrical life savers, defibrillators “Defibrillation has become an integral part of the emergency response routine. In fact, the American Heart Association considers defibrillation a basic life support skill for paramedics and rescue workers.” (DIRECT QUOTE) The human heart is arguably the most vital organ of the human body, as its coordinated and controlled two-part pumping is necessary to supply blood to the entire body. This supply rate is regulated by the…

Currently only 21% of Americans meet the physical activity guidelines set forth by the Centers for Disease Control and Prevention (CDC). This has become a major concern in today's society, as many of its effects are being seen. One of ten deaths worldwide result from insufficient physical activity (WHO). Physical activity is any type of movement that requires energy. Being physically active contributes to a person's overall fitness, which is a general state of health and wellbeing. Physical…

The cardiovascular system is the bodies system that is in charge of regulating blood throughout the body. The main job of the cardiovascular systems are transportation of blood which allows the body to receive oxygen, nutrients, and hormones while disposing of wastes. The second job of the cardiovascular system is protection via the white blood cells. White blood cells clean up cellular debris and fight pathogens that have entered the body. The cardio vascular system will also offer protection…

The heart is considered the “engine of life” through its ability to rhythmically pump oxygen rich blood throughout the body to supply life. Unfortunately, this vital organ is vulnerable to damage through actions of everyday life ranging from smoking, diet, physical inactivity, and consumption of alcohol. Damage to the heart results in heart disease, also known as cardiovascular disease. Because of the vast complexity of the heart, heart disease branches off into various categories including…
