Quantitative concept mapping reveals that while students
Area of Science:
- Physiology Education
- Cognitive Science
- Educational Psychology
Background:
- Quantitative concept mapping offers a scientifically rigorous approach to analyzing concept learning.
- Previous research has explored the structure of student concept learning in pulmonary physiology.
Purpose of the Study:
- To extend quantitative research on student concept learning in pulmonary physiology.
- To analyze the structure of concept knowledge in medical and veterinary students and their instructors.
Main Methods:
- Utilized Pathfinder scaling to generate concept maps for students and instructors.
- Evaluated concept maps for coherence, student-instructor similarity, and correlation with examination scores.
Main Results:
- Student and instructor concept maps demonstrated coherence.
- Student concept maps showed increased similarity to instructor maps post-instruction.
- Concept map similarity did not correlate with final examination performance.
Conclusions:
- Student knowledge structures in pulmonary physiology evolve during instruction.
- Factors beyond concept map similarity may influence examination performance.
- Further research is needed to understand variations in student and faculty knowledge structures.

Respiratory Volumes and Capacities I
Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...
Overview of Pulmonary Circulation
The pulmonary circulation is a vital system in our body that acts as a bridge between the respiratory and cardiovascular systems. It serves as a transport network for deoxygenated blood from the heart to the lungs and then returns oxygen-rich blood back to the heart.
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...

Gross Anatomy of the Lungs
The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...
Pressure Relationships in Thoracic Cavity
Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs during...

Respiratory Volumes and Capacities
The respiratory system is responsible for the intake of oxygen and the expulsion of carbon dioxide from the body. Respiratory volumes describe the volume of air in the lungs at different phases of the respiratory cycle. Tidal volume is the air breathed in and out during normal, quiet breathing. Inspiratory reserve volume is the air that can be forcefully inspired beyond the tidal volume. In contrast, expiratory reserve volume refers to the air that can be expelled from the lungs after a normal...
Application of Integration: Problem Solving
The process of breathing involves the periodic intake and expulsion of air, known as the respiratory cycle, which typically lasts about five seconds. Modeling the volume of air inhaled into the lungs as a function of time provides insight into both the dynamics and efficiency of pulmonary ventilation. This volume is determined by integrating the airflow rate over time, which captures the cumulative effect of air entering the lungs.Sinusoidal Model of AirflowAirflow during respiration is not...
