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

Aging is something that continuously happens throughout life‚ which produces a lot of changes throughout the body. With that being said‚ many changes throughout the body affect the respiratory system. As individuals age‚ bones of the body become thin‚ weak‚ and change shape. The ribcage is affected by this change and can alter a person’s breathing as it becomes unable to expand and contract the way it used to. Muscles in the body also become weak. If the muscle that supports breathing‚ called the

This essay will explain the function of the respiratory‚ digestive and cardiovascular systems and how they work together to produce nutrients and oxygen to the cells for cellular respiration (energy for the body) The first system in the body is the digestive system. When food enters the mouth the salivary glands secrete saliva which mixes with the food. This makes it easy to chew and swallow. Once the food has been chewed enough the food travels down the oesophagus to the stomach. Once the food

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
