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

Phoenix Material Roderick Tabigne Respiratory System Lab – Week Six Introduction The respiratory system consists of the upper respiratory tract (the nasal cavity‚ pharynx‚ larynx‚ trachea‚ and bronchi) and the lower respiratory tract (the lungs). As you learn about the various diseases that affect the respiratory system‚ it is important for you to understand the structures that can be affected by disease. Complete this lab to become familiar with a healthy system and to identify diseases related to

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
