normal breathing is about 500 mL‚ this volume of air is called the tidal volume.In addition‚Vital capacity is the largest volume of air an individual can move in and out the lungs.Human Lung capacity can be measured in many different ways‚ one way of measuring human lung capacity is by using a ballon.The purpose of this experiment is to determine the vital capacity of your lungs and to understand the relationship between tidal and reserve respiratory volumes.

Premium Lung Respiratory physiology Oxygen
Respiratory Rate and Tidal Volume [pic] The total amount of air moved in and out of the lungs each minute (pulmonary ventilation) depends upon 2 factors: size of each breath (tidal volume) and number of breaths/minute (respiratory rate). For example‚ suppose your tidal volume is 500 mL (0.5 liters) and you breathe 15 times/minute. Your pulmonary ventilation = 15 breaths/min x 0.5 L/breath = 7.5 L/min. Pulmonary Ventilation = (Respiratory rate; breaths per minute) x Pulmonary Ventilation

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 of the two. Tidal volume is more effective at increasing minute ventilation than respiratory rate‚ however‚ if a subject is unfit they will be required to increase

Surfactant Surfactants are also known as ‘surface active agents’. They are usually organic compounds that contain hydrophobic tails and hydrophilic heads. They have wetting‚ emulsifying and dispersing properties‚ which can be used to improve the wetting ability of water‚ break up stains and keep the dirt in the water solution to prevent re-deposition of the dirt onto the surface from which it has just been removed. Surfactant can act as wetting agent as it lowers the surface tension of water.

It is equally terrifying or even a death sentence‚ to know the exact hour when you die. Today‚ however‚ with the development of mechanical respirators‚ electronic pacemakers‚ and other medical technologies‚ it has created the possibility of a greater temporal separation between various system failures. A person may slip into coma or lose consciousness a decade or more before his heart and lungs fail‚ for example. Meanwhile‚ interest in the availability of transplantable organs has provided an incentive

firms). This means the foci of the course are the identification of the entrepreneurial opportunity‚ the interactions among the entrepreneurial team‚ the idea and the environment. We define entrepreneurship as the process of how‚ by whom‚ and with what consequences opportunities to discover future products and services are identified‚ evaluated and exploited. The main questions are how entrepreneurship develops in the economy and how we can understand this process from different perspectives.

What Happens When the Supply Curve Shifts Student Feb 17‚ 2013 Principles of Microeconomics The Supply Curve: Price is usually a major factor in the quantity supplied to the market. For a particular good with all other factors held constant a table could be constructed of price and quantity supplied based on observed data. This table is called a supply schedule‚ example: Supply Schedule Price Quantity Supplied 1 12 2 28 3 42 4 52 5 60 By graphing this data the
