Cardiovascular Unit PPT. Make a Heart. You will need a worksheet Share instructions Colored pencils/markers Needs to be done by end of hour for use in next class. Circulatory Worksheet ( label #4-7 together). REMEMBER the difference between Veins and Arteries!!.
E N D
Make a Heart • You will need a worksheet • Share instructions • Colored pencils/markers • Needs to be done by end of hour for use in next class
Circulatory Worksheet F/U: • Looking at # 10 &11: The ventricles push blood out of the heart. If they are not working perfectly : • What is that persons body not receiving • What would the long term affects be • How could you treat it • On the back of Worksheet, list and define the directional terms • On the heart diagram label the anatomical structures that are on the worksheet. There should be 7+ (actually label the heart diagram)
Heart Anatomy: Flashcards: • You will need to: • Cut • Use BLUE, RED and BLACK colors
Cardiovascular Medical Abbreviations • Using Appendix B fill in chart • Please put packet back when finished

Circulatory Vocabulary • Using your Word Part chart fill in the vocab terms that you are able to • Make a GUESS and do your BEST!
Add to your Vocabulary: • Atherosclerosis: narrowing/hardening of blood vessels caused by deposits of fatty material containing calcium and cholesterol • Coronary: pertaining to the heart • Diastolic: dilation of the heart, resting phase or filling of the ventricles • Hepatic circulation: path of blood from the intestines, GB, pancreas, stomach and spleen THROUGH the liver • Pulmonary circulation: heart to lung. Carries de-oxygenated blood from the right ventricle to the lungs and returns oxygenated blood to the left atrium of the heart • Systemic circulation: general circ to systems. Oxygenated blood from the left ventricle to tissues of the body, returns de-oxygenated blood to right atrium • Systolic: contraction of the ventricles
Path of Blood = Blood Flow 3. Right atrium 4. Tricuspid valve 5. Right ventricle 2. superior/inferior vena cava 6. Pulmonary arteries 1. All parts of the body 7. lungs 12. aorta 8.Pulmonary veins 11. Left ventricle 10. bicuspid/mitral valve 9. Left atrium
Heart Circulation THREE TYPES • Pulmonary Circulation: Flow of blood between the heart and lungs • Systemic Circulation: Flow of blood between the heart and the cells of the body • Coronary Circuloation: Flow of blood within the heart
Blood Flow BLOOD VESSELS • Arteries carry blood AWAY from the heart - Largest = Aorta - Heart muscle contractions pump blood through arteries • Veins carry blood TOWARDS the heart - Largest = Superior/Inferior Vena Cava - Valves prevent blood from returning to heart - Skeletal muscle contractions move blood through veins
Blood Flow Continued… HEART VALVES • Controls blood flow • Valve between Left Atrium and Left Ventricle = bicuspid • Valve between Right Atrium and Right Ventricle = tricuspid • Pulmonary and Aortic Valves STOP the back flow of blood into the heart
Structures • HEART • Beats 72 times a MINUTE • 100,000 times a DAY • 3 Trillion times in a LIFETIME! • Circulates about 5-7 liters of blood • BLOOD VESSELS • Arteries • Veins
Functions • Transport nutrients and oxygen • Transport waste to kidneys • Distribute hormones and antibodies • Help control body temperature and maintain homeostasis
THE HEART • 2 Sided double pump • Is about the size of your fist • Lies in the Thoracic Cavity between the lungs
Heart Tissue • Endocardium: smooth membranous lining inside the heart • Myocardium: muscle tissue that is contractile, thickest layer
Heart Tissue Continued… • Epicardium: Outermost layer of the heart • Pericardium: covers the whole outside of the heart
Parts of the Heart • Divided into right and left sides • 2 chambers in each side, for a total of 4 chambers • Atrium: top, where blood enters (“top of tree”) • Ventricles: bottom, where blood leaves (“vents at the bottom”) • Left and right sides separated by a partition called a septum
Cardiac Conduction System • Electrical Impulses produce a wave that can be recorded on the ECG • Consists of… • Sinoatrial (SA) node • Atrioventriclular (AV) node • Bundle of His (AV Bundle) • Bundle Branches • Purkinje Fibers (network)
SA NODE • Located in the upper right part of the atrium • Is a natural pacemaker • Fires at a rate of 60 to 100 times per minute • The heartbeat starts in the SA node
AV NODE • Located in the floor of the right atrium • Delays or slows the electrical impulse • Fires at a rate of 40 to 60 time per minute • Can take over if the SA node is not working
Bundle of His • Located next to the AV node • Transfers the electrical impulse from the atria to the ventricles
Bundle Branches • Located along the left and right side of the intraventricular septum • Act as pathways or a fork in the road • Impulses in the bundle branch perform the important work of making the heart muscle contract
Purkinje Network • Provide an electrical pathway for each of the cardiac cells • Activate the left and right ventricles simultaneously causing the ventricles to contract
Pulse • Use Reading Packet to fill in the Pulse worksheet
Heart Sounds • Lubb Sound • Heard first • Mitral and tricuspid valves closing between the atria and ventricles • Dupp Sound • Heard second • Shorter and higher pitched • Closing of the aortic and pulmonary valves as blood is pumped out of the heart • Murmurs • Abnormal or extra sounds http://depts.washington.edu/physdx/heart/demo.html
Blood Pressure • Systolic = contraction of the ventricles • Diastolic = relaxation of the ventricles • Normal BP= 120/80 (systolic/diastolic) • Healthy systolic is less than 140 and greater than 90 • Healthy diastolic should be less than 100 http://www.nejm.org/doi/full/10.1056/NEJMvcm0800157
Blood Pressure Readings • Use Reading Packet fill in the Blood Pressure worksheet
