Respiratory lab report

respiratory cycle lab report

Please go over expectations for each section of the lab report with the students. A possible error might have been that the room was too noisy to accurately hear the sounds of Korotkoff when measuring blood pressure. There are fissures in the lungs that divide them into lobes: two in the left lung and three in the right.

How to calculate residual volume

Since the heart rate increases during exercise to deliver more oxygenated blood to the muscles, there is a larger volume of blood traveling through the vessels, which increases blood volume Waters and Tomicek. The bronchi branches off into alveoli and then directly in to the bloodstream. Introduction The respiratory system is responsible for O2 and CO2 exchange between the atmosphere and the body. This includes gas exchange of oxygen into the blood stream and carbon dioxide into the atmosphere. This area serves as a conduit for food and air. Overall, there was a slight decrease in hemoglobin saturation during exercise and then a slight increase during the recovery period for all three subjects. The epiglottis is made of a more flexible elastic cartilage than the hyaline cartilage of the larynx. The results for hemoglobin saturation Figure 5 also did not show any major changes during exercise. This heat then travels to the surface of the skin to be released, which would increase measure of body temperature Martini, Nath, and Bartholomew. We expected to see these results because during exercise, the muscles need to make a lot more energy in the form of ATP in order to keep the body moving. Related Interests.

University of California, Santa Barbara. The movement of the ribs upwards and outward. After each group has completed the lab, each student will complete the lab report using the data collected.

I recommend using the lab report to assess mastery of the lesson objectives and vocabulary. The partner maintained the restriction through inspiration, expiration, and another inspiration.

Respiratory lab report

It is continuous with the posterior nasal aperture and passes air only. The bronchi branches off into alveoli and then directly in to the bloodstream. Recognize the different laboratory tests used for assessing fetal lung maturity. We hypothesized that temperature would increase during exercise because when respiration occurs, some of the energy produced is lost as heat. Series 1 refers to subject 1, series 2 refers to subject 2, and series 3 refers to subject three. The teacher will explain that the objective of this lab is to discover if athletes have a bigger or smaller total lung capacity TL than non-athletes, and if athletes have a faster or slower heart rate than non-athletes. The student subject information sex, birthdate, ethnicity, height, weight, smoker or non-smoker was entered into the MicroLab Spirometer. Because the main effect of hyperventilation is a decrease in PCO2, BHT can increase because the body does not arrive at the PCO2 that triggers the respiratory center to stimulate expiration as quickly as in a normally-ventilated individual Widmaier et al. Harlow: Pearson, The lower vocal folds or true vocal cords. Air can also enter the respiratory tract through the mouth and then into the pharynx, a funnel- shaped structure, commonly called the throat.

What can you predict from the lung capacity and volume data from the spirometry test. Formative Assessment The purpose of the formative assessment is to use the results to better understand common misconceptions and concepts that your students are struggling.

The teacher will ask each student to make a hypothesis for both concepts and explain why they feel that way.

Respiratory system lab activities high school

The muscle fibers arise from the xiphisternum, lower six ribs and the lumber vertebrae. In the next part of the lab, we operated the model lung and learned about many of the features behind the mechanics of respiration. Because the main effect of hyperventilation is a decrease in PCO2, BHT can increase because the body does not arrive at the PCO2 that triggers the respiratory center to stimulate expiration as quickly as in a normally-ventilated individual Widmaier et al. The results for hemoglobin saturation moderately supported out hypothesis that the percentage of saturation would decrease throughout exercise. The teacher will explain the formal assessment expectations at the end of the lab. It appears as though there may have been a slight increase during the exercise period and a slight decrease during the recovery period, but there were no major changes. RPD arises from an inability to expand the thoracic cavity or lungs; it decreases lung compliance.

OPD arises from narrowing or blockage of the airways; it increases airway resistance thereby decreasing airflow. Because the main effect of hyperventilation is a decrease in PCO2, BHT can increase because the body does not arrive at the PCO2 that triggers the respiratory center to stimulate expiration as quickly as in a normally-ventilated individual Widmaier et al.

The mucous membrane of the larynx is made up of two folds: I.
