arteriostenosis coronary Hepatic circulation Systemic circulation systolic Circulatory: • Hepatic circulation: Vocabulary continued

• Arteriostensosis: • Narrowing of blood vessel • Coronary: • Pertaining to heart • Pulmonary circulation: • Path of blood from the intestines, GB pancreas, stomach and spleen through the liver • Systemic circulation: • General circulation to the systems. • Heart to lung, carrying de-oxygenated Oxygenated blood from the left blood from the right ventricles to the ventricle to tissues of the body lungs and returning oxygenated blood returning de-oxygenated blood to to the left atrium of the heart the right atrium Circulatory: • Blood pressure: Vocabulary continued • The force of the blood against the walls

• Stethoscope: • Instrument used to listen to body sounds such as the heart beat • Systolic: • Contract: • Contraction of the ventricles • To shorten, reduce in size • Diastolic: • Rate: • Dilation of the heart, resting phase, or filling of the ventricles • Expression of speed or frequency. Number of contraction of the heart per minute • Cardioversion: • Restoration of normal heart rhythm by electric shock • Vessel: • Tubule in the body that carries fluid • Aneurysm: • Blood vessel that bulges because of a weakness in the wall • Atherosclerosis: • Narrowing / hardening of blood vessels caused by deposits of fatty material containing calcium and cholesterol • Infarction: • An area of tissue death caused by loss of oxygen as a result of obstruction termrrhage Practice quiz: Forms Video segment: watch the first time, then take notes

Video on website Heart Circulation

• Pulmonary: Flow of blood between the heart and lungs • Systemic: Flow of blood between the heart and the cells of the body • Coronary: Flow of blood within the heart Blood Flow • 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 Cont’d

• Valves • control blood flow • Valve between left atrium and ventricle = bicuspid • Valve between right atrium and ventricle = tricuspid • Pulmonary and aortic valves stop the back flow of blood into the heart W.A. follow up: in lab group 1. Correct answers 2. Looking at # 10 &11: The ventricles push blood out of the heart. If they are not working perfectly : a) What is that persons body not receiving b) What would the long term affects be c) How could you treat it

3. On the back of W.A. list and define the directional terms 4. On the heart diagram label the anatomical structures that are on the worksheet. There should be 7+ (actually label the heart diagram) Structures • Heart • Blood Vessels • Beats 72 times a minute • Arteries • 100,000 times a day • Veins • 3 Trillion times in a lifetime! • Circulates about 5-7 liters of blood Functions

• Transport nutrients and oxygen • Transport waste to kidneys • Distribute hormones and antibodies • Help control body temperature and maintain homeostasis Heart

• 2 Sided double pump • Is about the size of your fist • Lies in the thoracic cavity between the lungs Heart Tissue

• : smooth membranous lining inside the heart

• Myocardium: thickest layer, muscle tissue that is contractile. Heart Tissue Cont’d

• Epicardium: outermost layer in the

• Pericardium: covers the 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 • Ventricles: bottom, where blood leaves • Left and right sides separated by a partition called a septum Review 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) • • (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 • 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

What separates the left and right side of the heart 4. What are the 4 chambers of the heart 5. What keeps blood from flowing back into a chamber of the heart Reivew:

Infraspinatus 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 = ventricle relaxation • Normal BP= 120/80 (systolic/diastolic) • Healthy systolic is less than 140 and greater than 90 • Healthy diastolic should be less than 100
