Review for Cardiac Exam K ANATOMY REVIEW

Test Monday 3/30/15 – K ANATOMY Heart Anatomy – Chambers, structures and flow of blood, Coronary artery function Layers of the heart: 1. Pericardium (sac) – Epicardium, Parietal Pericardium 2.Myocardium – Muscle 3.Endocardium – epithelial lining Remember this diagram from your JOURNAL!

Key Vocabulary: Systole, Diastole, Bradycardia, Tachycardia, Angina Pectoris, Electrocardiogram, P-Wave, QRS-Complex/Wave, T-Wave, Vasoconstriction, Vasodilation Artery, Vein, Capillary, Arteriole, Venule, Lumen **All vocabulary words above are found in the 7 page packet, that starts with “The Pulmonary & Systemic Circuit”

The Pulmonary and Systemic Circuit The pulmonary circuit – HEART TO LUNGS AND BACK The systemic circuit – HEART AND BODY AND BACK

Electrical Conduction System of the Heart Be able to: 1.Label all electrical conducting structures: SA Node (pacemaker), AV Node, Bundle of His, Bundle Branches, Purkinje fibers 2.Show the path or identify the path of impulse conduction 3.Correlate what is occurring in these structures to an ECG.

ECG- Electrocardiogram What happens at the P wave? What happens at the QRS complex? What occurs just after the R wave? What occurs at the T Wave?

Heart Sounds Lupp Dupp First heart sound (shorter)– AV valves close, semilunar valves open Second heart sound – Semilunar valves close Know all the names of the AV valves – Left AV valve= Mitral valve, Bicuspid Right AV valve = Tricuspid valve

The test… 50 + questions, multiple choice and the rest matching and labeling Be able to answer questions at a higher level of thinking – Example: (this question is NOT on the test) The function of the chordae tendineae is to a. anchor the semilunar valve flaps & prevent backward flow of blood b. anchor the AV valve flaps and prevent the backflow of blood into the atria c. anchor the bicuspid valve flaps and prevent backflow of blood into ventricles d. anchor the aortic valve flaps and prevent backflow into the ventricles

Types of questions… What occurs during ventricular systole? What occurs during atrial systole? **Notice I am not asking you to simply IDENTIFY something but you have to know a little bit of vocabulary and APPLY what you know to THINK THROUGH your question. Some questions may involve sequences, some may simply be identification but BE PREPARED to answer questions above the simple level of identification only.

Resources: Your Journal, E-Text, any worksheets done in class Youtube – Khan academy has great videos on Cardiac Cycle, heart sounds, Heart Anatomy etc… Check my site for the links to the McGraw hill Animations THINGS TO DO: Quiz each other with a blank heart diagram – identify structures and path of blood Quiz each other with ECG diagram, electrical conducting structures of the heart Quiz each other on vocabulary
