Measuring of Lung Capacity Introduction This lab report is over the functions of the lungs and a better understanding of how the respiratory function happens within your body. You will be measuring the amount of air you breathe in and out. This function is called tidal volume‚ which is about 500 cc of air. Second portion of the testing procedure will be determining the amount of vital capacity or maximum amount your lungs can expel. You will be working in pairs with a lab partner and take turns recording

Lung Volume Activity The graph below is called a spirograph. It represents the amount of air that moves into and out of the lungs with each breath‚ as measured by a device called a spirometer. (The terms that are used to describe the features of a spirograph are explained below.) • Tidal volume is the volume of air that is inhaled and exhaled in a normal breathing movement when the body is at rest. • Inspiratory reserve volume is the additional volume of air that can be taken into the lungs

Method 1) Take a "volume" measuring device‚ and fill it with the total amount of water‚ the bottle can hold. We then put the same‚ empty bottle into the container‚ in a way‚ that it sinks to the bottom of the akwarium. We can then measure the new height and multiply it by the volume of the liquid. This will clearly give us the volume of a bottle. Method 2) We could pour water into a 0‚5 litre coke bottle‚ and weigh how much it would weigh. We could do the same thing with an empty bottle. The

LUNG CAPACITY Lung capacities are combinations of specific lung volumes. The lung capacities are measurements of two or more volumes. The total lung capacity (TLC) is a measurement of the total amount of air that the lung can hold; normally it is 6 litters for adult male and 4.2 litters for an adult female. The vital capacity (VC) measures the maximum amount of air that can be inhaled or exhaled during a respiratory cycle. The Residual Volume (RV) is the amount of gas remaining the lungs after a

Text: Measuring economic activity There are a large number of statistics produced regularly on the operation of the world’s major economies. The UK’s economy is no exception in this respect. You will probably have noticed that often the headlines in newspapers or important items on television news programmes relate to economic data and the implications for individuals and businesses. A prime example of this occurs when interest rates are increased: the media responds by highlighting the adverse

exist between gender or height with lung capacity of Year 9 students ! ! ! INTRODUCTION The capacity of our lungs is the volume of air our lungs can hold. Our lungs have a greater capacity than we use when we take a normal breath. Scientists use various terms to describe the different components of lung capacity. Tidal Volume is the amount of air breathed out in a single normal breath (inhalation and exhalation). The Inspiratory Reserve Volume is the amount of air you can inhale over

Measuring Brain Activity Most of the noninvasive imaging methods estimate brain activity by changes in blood flow‚ oxygen consumption‚ glucose utilization‚ etc. Discuss the potential problems with using this type of indirect measure. The brain is the control center of the human body. It sends and receives millions of signals every second‚ day and night‚ in the form of hormones‚ nerve impulses‚ and chemical messengers. This exchange of information makes us move‚ eat‚ sleep‚ and think.

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 their respiratory rate as they cannot breath as deeply as someone with

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
