Purpose: The purpose of this lab is to learn basic steps that are involved in respiration. The idea is to learn the structures of the respiratory system. Materials: The materials needed for this experiment are prepared slides of trachea tissue and lung tissue. We will also need a microscope. Procedure: The procedure is to take out a microscope and place it on your desk, plug it in and turn it on. Next, get the slides from the professor.
Place the prepared slide of the trachea tissue into the slot and use the fine and course adjustments in order to focus in on the specimen. Then place the slides of the lung tissue into the slot and use the fine and course adjustments again, to focus in on the specimen. Next, hold you breathe after a normal inhalation and record the time it takes until you need to breathe. Then repeat this holding your breath after a normal exhalation and record the time it takes until you need to breathe again. Run in place for two minutes and try to hold you breathe record the time it takes you to breathe again. Then hyperventilate for 30 seconds.
Have you partner time you as you hold your breath, record the time it takes until you need to breathe again. Now, have you partner hyperventilate for a full minute.
