As the subject enters the exercise phase there is an increased metabolic demand due to the heightened workload of the skeletal muscles and organ systems. In order to accommodate this rise in oxygen demand there must be an increase in the subject’s minute ventilation. The rise in minute volume‚ with exercise‚ could be accomplished by increasing the volume of each breath‚ the tidal volume‚ increasing the respiratory rate or by some combination of the two. In the subject’s case it was a combination

Laboratory report investigating the equine respiratory and cardiovascular systems Introduction The respiratory and cardiovascular systems of the horse work together to transport oxygen around the body and play an essential part in providing the horse with its increased need for oxygen during exercise. They allow the musculoskeletal system to use energy to facilitate motion. The cardiovascular system comprises the heart‚ blood vessels and blood. The heart pumps blood around the body

Asthma: Disease of the respiratory system Breathing‚ the act of inhaling and exhaling of air. Oddly enough this process is an absolute necessity for life and yet we do not control it. There are two systems involved in our ability to breathe one is the parasympathetic nervous system and the other is the respiratory system. The parasympathetic nervous system controls the body ’s unconscious actions that are necessary to live such as the beating of the heart. The Respiratory system mainly consists of

Physiology of Respiratory System Overview Cells in the body require oxygen to survive. Vital functions of the body are carried out as the body is continuously supplied with oxygen. Without the respiratory system exchange of gases in the alveoli will not be made possible and systemic distribution of oxygen will not be made possible. Thetransportation of oxygen in the different parts of the body is accomplished by the blood of the cardiovascular system. However‚ it is the respiratory system that carries

Respiratory system: Minute ventilation is the quantity of oxygen which is taken in by your lungs per minute. When we exercise there is a higher oxygen intake per minute due to a higher breathing rate‚ we will also need more oxygenated blood cells to go round to the muscles in use to help try and prevent muscular injuries. The reason why when minute ventilation increases is positive to an athlete is because there is a higher intake of oxygen and nutrients needed. This will mean that the athlete
