Extract of sample

During exercising process, the body acclimatises by enhancing its capacity to draw in the oxygen by increasing the breathing rate; the lungs expand in volume to accommodate the extra oxygen requirement (Raj et al., 2005; Watanabe, 2003). The availability of oxygen and force increase the circulation of blood rich in oxygen to the muscles for the continuation of exercise. However, during rest, the muscle capacity decreases, which lowers the blood flow and the breathing capacity leading to reduced pulse rate. The experiment aimed to test the differences in heart rate and blood pressure before exercise (resting status), jumping, and two minutes after jumping.
The materials needed to carry out the experiment include the pencil and paper for recording the data, the room for carrying out the jumping jack, a group of participants (14) with equal numbers from both sexes, and a timer or a stopwatch. The participants were prepared by allowing them to rest for about 15 minutes. Besides, they were allowed to take enough water during the exercises because bodies lose water while exercising. The procedure involves requesting participants to place their fingers under their wrist and count the heartbeat for 30 seconds. The number gotten was multiplied by two to get the heartbeat, the same procedure was repeated after taking 20 jump jacks. The same procedure was used to record the heart rate while resting.
The findings relate to previous findings that found that continuous exercising conditions the heart to get more efficient in carrying out the exercise (Raj et al., 2005; Watanabe, 2003). There were significant differences between the resting data and the data obtained during exercising. These show that increase in exercise increases the heart output to acclimatise with the requirement of oxygen and blood to the muscle cells involved in the exercising process. The participants were given water to cool down the heat produced during ...Show more


The amount of oxygen expenditure can be three times the quantity of oxygen used during rest. These requirements demand that the heart increases its…

Human Endocrime System
Hormones are specific to their target cells which have receptors that bind to individual hormones. These messages perform a variety of tasks, such as, controlling enzyme production and modifying cell structure and activity (607). These activities are strictly controlled by a negative feedback system in order to maintain homeostasis and coordination between cells and tissues.

However, according to a 2007 report by the Centers for Disease Control and Prevention, overdoses resulting from prescription drugs outnumber those from non-prescription drugs in the 26,000 fatal cases of drug overdose in the United States each year (Davis).Apart from these fatal cases, around 120,000 Americans every year suffer from the harmful and debilitating effects of overdosing on painkillers (Davis). Nevertheless, one should give equal attention to non-prescription drugs. This is due to the fact that drugs like cocaine, marijuana and methamphetamine still account for many horrific complications and fatalities that result from drug overdoses and that claim thousands of lives in America each year (“Overdose”).
