Study Notes
IFS 1 Exam 1 Study Guide
- Exam consists of 50 multiple choice questions, covering units 1 and 2. Equal distribution of questions per unit.
- Key concepts include: movement origin, key players, factors affecting movement, and optimal movement.
- Review unit introduction slides and associated video material to aid studying.
Unit 1: Systems & Thorax
- Overview of the Cardiovascular System
- Understand the anatomy and function of major organs (heart, blood vessels, blood).
- Heart Anatomy: Endocardium (internal), Myocardium (cardiac muscle), Epicardium (external), Pericardium (membranous sac).
- Lung Anatomy: Superior and Inferior Lobes (left and right), Oblique and Horizontal Fissures (right lung only).
- Cardiovascular System & Movement: How cardiovascular function impacts movement (increased heart rate to meet oxygen demands of muscles).
- Blood Vessel Types:
- Arteries: Vessels carrying blood away from the heart.
- Veins: Vessels carrying blood back to the heart.
- Heart Location & Relation to Other Thoracic Structures: Located in the ventral thorax, apex pointed toward the left, base behind sternum, anterior to esophagus and inferior to the trachea.
Unit 2: Information Not Provided in OCR
- Additional Information: The provided text contains information about the cardiovascular system and its relation to movement. It also covers the structure and pathway of blood flow through the heart and the body, as well as the pathways oxygenated and de-oxygenated blood follow. It also has information about valves and muscle types. Additional information not present in this OCR is needed for a complete study guide.
