Case summary:
In the given condition the following sets of experiments were conducted;
Experiment A- The subjects were asked to run for 30seconds and then told to sit down and relax.
Experiment B- The subjects were asked to run while holding their breath during running.
In both the conditions, the depth and rate were analyzed.
Adequate information:
The depth and rate of respiration depends on the physical stress that a body is subjected to. So, in the given conditions, due to the different levels of stress on the body, the depth and rate of respiration will vary.
To determine:
The basis of respiration depth and rate increase in a person subjected to physical activity in different conditions.
Given information:
The depth and rate of respiration of two sets of people are observed. One set of people were asked to run for 30 seconds and then allowed to relax. The other set of people were asked to run with their breath held followed by relaxation.
Introduction:
The process of respiration involves inhalation and exhalation. Inhalation is the process of intake of oxygen rich air, while exhalation on the contrast is expiration of carbon dioxide. The rate of this process is termed as respiration rate which may vary depending on conditions such as; health, age and physical activity.

- When considering the movement of air into the balloons (representing the lungs), which of the following would you have to do? a. pull down on the diaphragm mimicking the contraction of the diaphragm in inspiration b. push up the diaphragm mimicking the relaxation of the diaphragm in expiration c. push up on the diaphragm mimicking the contraction of the diaphragm in expirationarrow_forwardWould the respiration rate be different for a person who had just exercised instead of sitting in the lab? a. No, the respiration rate would be the same. b. Yes, the respiration rate would be slower because the exercise slows respiration and oxygen uptake. c. Yes, the respiration rate would be faster since the person needed more oxygen while exercising.arrow_forwardUsing the text provided (ignore questions in bottim right of the text) Describe how altitude sickness is treated, including a reference about how Le Chatelier's Principle leads to the restoration of equilibrium.arrow_forward
- One technique for artificial respiration is mouth-to-mouth resuscitation. The rescuer takes a deep breath, blows air into the patient’smouth, and then lets air flow out. The process is repeated. Explain thefollowing: (1) Why do the patient’s lungs expand? (2) Why does airmove out of the patient’s lungs? (3) What effect do the Po2 and thePco2 of the rescuer’s air have on the victim?arrow_forwardCalculate the beats per minute using the Delta T and # of R-waves in the table.arrow_forwardWhich of the following combinations would all result in an increase in stimulation to breathe?

- Which of the following statements about the oxygen-binding curves is FALSE? Select one: a. During normal activity (not exercising) the blood PO2 rarely falls below 40 mmHg. b. The PO2 and hemoglobin dissociation curve for myoglobin is to the left of fetal hemoglobin. c. The blood returning to the lungs is still 75% saturated with oxygen. d. A larger decrease in PO2 is needed for hemoglobin to drop from 100% to 75% O2 capacity than from 75% to 50% O2 capacity. e. During high metabolic activity the PO2 and hemoglobin dissociation curve would be expected to shift to the left of normal.arrow_forwardUsing the Anatomy and Physiology of the Human Body to Correlate Patient Sign and Symptoms What happens in our body every second without having to even think about it is one of the amazing things about its functions. you learned how important it is to know the anatomy and physiology of the human body in order to correlate the signs and symptoms of patients.

- A forearm skeletal muscle has a hemoglobin concentration of 92 microM. An arterial occlusion of the upper arm determines a decrease in saturation at a rate of 15% per minute, and no change in blood volume. Find the muscle oxygen consumption in units of micromolo2/(100 mltissue-min).arrow_forwardWhen researchers first discovered that airflow through a bird’s paleopulmonal parabronchi is unidirectional, the question arose as to whether gas exchange is countercurrent, cocurrent, or cross- current. Some ingenious investigators carried out experiments in which they measured the efficiency of gas exchange between air and blood in duck lungs when parabronchial airflow was in its normal direction and when the direction of parabronchial airflow was artificially reversed. The efficiency did not change. How is this evidence against countercurrent and cocurrent gas exchange? How is this evidence for cross-current exchange?arrow_forwardThis article in the image illustrates what happens when you blow just above a piece of paper. Describe what you see.
