Overview of Anatomy and Physiology01:24

Overview of Anatomy and Physiology

Human anatomy is the scientific study of the body's structures. Some of these structures are very small and can only be observed and analyzed with the assistance of a microscope. Other larger structures can readily be seen, manipulated, measured, and weighed. The word "anatomy" comes from a Greek root that means "to cut apart." Human anatomy was first studied by observing the body's exterior and the wounds of soldiers and other injuries. Later, physicians were allowed to dissect the bodies of...
Pathophysiology of Cardiac Performance01:29

Pathophysiology of Cardiac Performance

Typical heart performance is influenced by heart rate, rhythm, myocardial contraction, and metabolism or blood flow. The cardiac muscle exhibits distinct electrophysiological features, including pacemaker activity and calcium channel control, which play a vital role in the heart's response to various drugs. The autonomic nervous system, comprising the sympathetic and parasympathetic branches, regulates heart rate. Sympathetic activation increases heart rate, while parasympathetic activation...
Gross Anatomy of the Lungs01:17

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...
Anatomy of the Circulatory System02:03

Anatomy of the Circulatory System

The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.
Exercise and Cardiac Output01:17

Exercise and Cardiac Output

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
Sustained exercise increases the muscles' oxygen demand, which can be met...
Overview of Systemic and Pulmonary Circulation01:15

Overview of Systemic and Pulmonary Circulation

The systemic and pulmonary circuits are crucial components of the circulatory system, working together to transport blood between the heart, lungs, and the rest of the body. The process begins with pulmonary circulation, where deoxygenated blood is pumped from the right ventricle to the lungs via the pulmonary trunk and arteries. Upon reaching the lungs, the blood becomes oxygenated and returns to the heart, specifically to the left atrium, via the pulmonary veins.
The oxygenated blood is sent...

Area of Science:

  • Medical Education
  • Physiology Pedagogy

Background:

  • Large medical classes present unique pedagogical challenges.
  • Effective implementation of supplementary learning programs is crucial for student success.

Purpose of the Study:

  • To assess the feasibility of a peer-teaching program in a large medical course (>350 students).
  • To determine the benefits and student perceptions of a near-peer tutoring initiative.

Main Methods:

  • A voluntary, case-based peer-tutoring program was piloted.
  • Near-peer tutors, selected for academic merit and trained in facilitation, led small groups.
  • Students completed pre- and post-tutorial quizzes and surveys.

Main Results:

  • Sixty-eight students participated, attending an average of four out of six sessions.
  • Post-tutorial quiz scores were significantly higher than pre-tutorial scores.
  • Student and tutor surveys indicated high satisfaction and positive perceptions, particularly regarding near-peer interaction.

Conclusions:

  • The peer-tutoring program is logistically feasible for large medical classes.
  • The program demonstrated significant academic benefits and was well-received by both tutors and students.
  • Near-peer teaching effectively enhances student problem-solving and engagement in physiology.
