circulationsystolic
Circulatory:
Vocabulary continued
• Arteriostensosis:
• Narrowing of blood vessel
• Coronary:
• Pertaining to heart
• Pulmonary circulation:
• Heart to lung, carrying de-oxygenated blood from the right ventricles to the lungs and returning oxygenated blood to the left atrium of the heart
• Hepatic circulation:
• Path of blood from the intestines, GB pancreas, stomach and spleen through the liver
• Systemic circulation: • General circulation to the systems.
Oxygenated blood from the left ventricle to tissues of the body returning de-oxygenated blood to the right atrium
• Systolic: • Contraction of the ventricles
• Diastolic:• Dilation of the heart, resting
phase, or filling of the ventricles
• Blood pressure: • The force of the blood against the walls
• Stethoscope: • Instrument used to listen to body sounds
such as the heart beat
• Contract: • To shorten, reduce in size
• Rate: • Expression of speed or frequency.
Number of contraction of the heart per minute
Circulatory:
Vocabulary continued
• 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
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 group1. 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
• 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
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: thickest layer, muscle tissue that is contractile.
Heart Tissue Cont’d
• Epicardium: outermost layer in the pericardium
• 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
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 interventricular 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

11. Levator scapulae
12& 13. Rhomboids
• Triceps Brachii
• Latissimus dorsi
Review: Guiding questions 1. What is the largest artery of the cardiovascular/circulatory system?
2. What are the blood vessel that carry blood from the upper and lower parts of the body
3. 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

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
• Read BP article/WS
