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

Video segment: watch the first time, then take notes

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

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)

• 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

Pulse

• Using reading packet fill in the Pulse

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
