Physiological Differences between Children and Adluts

Knowledge about human physiology dictates the approach that a teacher should use when handling children. Human physiology of a child differs from adult. Notably, adult language is different from child language. This paper identifies the physiological differences between adult and children, which influence their response to exercise or sport. Physiologists believe that major physiological differences that exist between adults and children influence their ability to respond to physical activities. Human body systems such as respiratory system and cardiovascular system among other systems influence the ability of an individual to handle a particular amount of physical exercises (Kirk, MacDonald, amp. O’Sullivan 2006:232). The physiological differences that exist between adults and children include difference in cardiovascular system, respiratory system, and ability of the human body to withstand fatigue. Adults have fully developed organ systems, which influence their ability to withstand strenuous exercises. On the other hand, children organ systems are still developing. Concerning these physiological differences, children are able to do a given amount of exercises (Armstrong, et. al. 2008:81). Another notable difference is the blood content of the body. Adult have large quantity of blood, which is responsible for oxygen circulation in the body. Cardiovascular system is responsible for the transportation of oxygen in the body from the heart to other parts of the body through the blood (Armstrong, 2007:128). Oxygen delivery to various parts of the body depends on the amount of blood pumped by the heart. Children have low volume of blood, which translate to the amount of oxygen supplied in various body organs. On the other hand, the pumping rate of the heart in children is higher than in adult. Another notable difference is ventricular size of the heart. Adults have large ventricular size compared to children. This influences the volume of blood pumped by the heart in each pumping stroke. Another notable difference between adults and children is that children have low tolerance rate to high temperatures and humidity. The respiratory system is responsible for gaseous exchange in the human body. Ventilation refers to the amount of gaseous exchange per minute. Ventilation is a product of tidal volume and the rate of breathing. Children breathe rapidly compared to adults because they have low tidal volume. Adults have well developed lungs, which explain the difference in breathing frequency between adults and children. The later have small organs thereby influencing the volume of air exchange. Respiration depends on surface area of the body to its volume ratio (Kincheloe, amp. Horn, 2008:123). The children have a high rate of respiration compared to adults. Physical activities and gender influence the rate of respiration. When an individual is doing a strenuous activity, the rate of respiration tend to increase. Gender differences influence basal metabolic rate. Women have a basal metabolic rate which low compared to men. This explains the difference in ability to handle strenuous exercises between girls and boys. Naturally, girls would handle simple physical exercises without straining. Environmental factors such as temperature and humidity influence oxygen supply in the human body. Physiologists observe that children response to high temperat
