Study Notes
IFS 1 Exam 1 Study Guide
- Exam covers units 1-2, 50 multiple choice questions, equal distribution of questions from each unit.
- Tie concepts to the main movement question: What is movement? Where does it originate? What are the key players? What influences optimal movement?
- Use guiding questions in the unit introductions to aid studying.
- Some video-based questions possible.
Unit 1: Systems & Thorax
- Cardiovascular System Overview: Know the anatomy and function of major organs, including the heart (endocardium, myocardium, epicardium, pericardium) and blood vessels. Also, know lung anatomy: superior, middle, and inferior lobes (left and right), and fissures.
- Cardiovascular System & Movement: How does the cardiovascular system function to support movement? (e.g., increased heart rate to meet oxygen demands). Which vessels carry blood away from the heart (arteries)? Which vessels carry blood to the heart (veins)?
- Heart Location: Know the heart's location in the thorax relative to other structures (e.g., lungs, sternum, rib cage).
Additional Information
- Blood Pathway: Understand the pathway through the cardiovascular system. Note which parts carry oxygenated and deoxygenated blood.
- Heart Valves: Know the valves (tricuspid, pulmonary, mitral, aortic) and their location in the heart. Their purpose is to prevent backflow of blood.
- Heart Muscle (Myocardium): The myocardium is composed of two main cell types: contractile cells and autorhythmic cells. Contractile cells contract due to a stimulated signal.
- Blood Circulation: Understand how blood flow relates to the electrical signals in the heart. Be able to identify P, PR segments, QRS complex, and T wave segments on an ECG.
- Cardiac Cycle: Define the phases of the cardiac cycle (systole and diastole). Compare the relationships between electrical signals, mechanical events, and contractility.
- Stroke Volume: The amount of blood pumped by one ventricle during a single contraction.
- Ejection Fraction: The percentage of end-diastolic volume ejected in one contraction.
- Regulation of Heart Rate: How does the autonomic nervous system regulate heart rate? What are the differences between sympathetic and parasympathetic control?
