Title: the mechanism of carbon dioxide and oxygen exchange in the respiratory of human Abstract The purpose of the experiment is to determine gas exchange activity in the respiratory system of human. The first lab for comparing the room and breathe temperature was to understand the function of the nasal cavity where the gas passed after an inhalation. The second lab for changing of chest circumference and abdomen circumference between inspiration and expiration was to know how the air moved in

exchange rate can make the real exchange rate Increase‚ which will stimulate export and restrict import. It means that the trade balance will be improved. When the rate rises‚ the price of export is cheaper by counting in foreign currency‚ and the price of import in domestic currency increases‚ which is called the price effect. The decrease of exchange rate makes the price of export cheaper‚ the export volume increase‚ while the import volume limit. This phenomenon is known as the volume effect.

As learned in the course text‚ we know that stressors can cause a lot of issues health wise. Using the textbook example of the Upper Respiratory Tract Infection and compare it with obesity. Like URTI‚ obesity effects physical‚ and psychological health which could potential cause more issues down the road. Looking at physical health‚ obesity can affect the immune system.

to her sinuses because her sinuses became an area that her nasal passages and pharynx could drain into. In here the drainage just sat there and became a breeding ground for bacteria. B) What is the Cough Reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing? a. The cough reflex is used to get things like irritants and fluid which causes us to have sputum out of the nasal passage and pharynx. The cilia or little hairs that are in our trachea is trying

Respiratory General Questions 1. What is the function of the epiglottis? a. The main function of the epiglottis is to prevent food and other particles from gaining entry into the trachea and other airways. 2. Do you see any anatomical reason why the right lung has more lobes than the left lung - and is subsequently larger and heavier? a. The right lung may be larger and heavier because it has more room to develop as such. The heart is roughly centered in the chest cavity; however‚ it is slightly

between the volume of a gas and the temperature of a gas at constant pressure. Verify Charles’s law. BACKGROUND INFORMATION The volume of a gas at constant pressure increases when the temperature of the gas is raised. This observation was first made by Jacques A. C. Charles in 1787. A quantitative study did not follow‚ however‚ until 1802‚ when Joseph L. Gay’ Lussac determined the relationship between the volume of a gas and its temperature. The relationship between the volume and the temperature

Obtain a 60 mL syringe‚ fill it with air‚ and connect the syringe to the gas-measuring device as indicated in the figure. Test your apparatus for gas leaks. If you can’t eliminate all leaks‚ see your lab instructor. B. If necessary‚ calibrate your gas-measuring device as indicated by your lab instructor. Fill your syringe to the largest volume mark on the syringe and reconnect

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
