CARDIOVASCULAR FITNESS Cardiovascular fitness is frequently considered the most important aspect of physical fitness because those who possess it are likely to have a lessened risk of coronary heart disease – the number one killer in our society. Cardiovascular fitness is also referred to as cardiovascular endurance‚ cardio-respiratory capacity and circulatory fitness. Regardless of the word used to describe it‚ cardiovascular fitness is complex because it requires fitness of several body systems

Cardiovascular system: The circulatory system: The circulatory system is made up of the vessels and the muscles that help and control the flow of the blood around the body. This process is called circulation. The main parts of the system are the heart‚ arteries‚ capillaries and veins. 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

Silaba Mpasu Physical Networking Unit 6 Exercise 1 Connector Installations Twisted-pair cable On a TWISTED PAIR CABLE I chose to install an RJ-45. This is the standard Ethernet connector for most systems used today. I would first measure out the length of cable that I would need. I would then use a wire cutter to cut the length that I need‚ leaving enough room for corrections and to open the wire. I would then use wire strippers to remove a small piece of the outer most jacket. I would then choose

Cardiovascular Diseases Cardiovascular disease is defined as a disease that affects any area of the cardiovascular system‚ including the heart and blood vessels‚ and covers a range of diseases such as arteriosclerosis‚ atherosclerosis and coronary heart disease. Diet plays a vital part in the prevention and control of these diseases however other manageable factors such as smoking and physical inactivity also contribute to the diseases if not controlled correctly. However corrective action or
Premium Atherosclerosis Blood Myocardial infarction
Cardiovascular The cardiovascular system is consists of the heart and network of arteries‚ veins‚ and capillaries that transport blood throughout the body. There are two primary circulatory loops in the human body: the pulmonary circulation loop and the systemic circulation loop. The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it

CHAPTER 6 MASTER BUDGET AND RESPONSIBILITY ACCOUNTING 6-16 (15 min.) Sales budget‚ service setting. In 2014‚ Rouse & Sons‚ a small environmental-testing firm‚ performed 12‚200 radon tests for $290 each and 16‚400 lead tests for $240 each. Because newer homes are being built with leadfree pipes‚ lead-testing volume is expected to decrease by 10% next year. However‚ awareness of radon-related health hazards is expected to result in a 6% increase in radon-test volume each year in the near future.

Neurophysiology of Nerve Impulses ACTIVITY 1 The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative
