CH 16 Cardiovascular

CH 16 Cardiovascula

QuestionAnswer
functions of the heart center of the circulatory system. Pumps blood through vessels for nutrition and oxygenation
heart has two pumps forces blood into lungs and the other pushes blood to the rest of the body
where is the heart located? in the thoracic cavity between the lungs called MEDIASTINUM
the thich middle layer of the heart and the thickest of all layers. It is composed of cardia muscle tissue myocardium
the outermost layer of the heart; it is slinglike pericardium
the thin outermost layer of the heart; it continous at the apex of the heart with the inner lining of the pericardium epicardium
heart's innermost layer. It is a thin layer composed of simple squamous epithelium over a layer of connective tissue endocardium
describe the circulation pathways 1) arteries 2) arterioles 3) capillaries 4) venules 5) veins
describe the electrical activity of the heart 1) (SA) sinoatrial node 2) (ACF) atrial conducting fibers 3) (AV node) atrioventricular node 4) ( BOH) Bundle of His 5) (BB) bundle branches 6) (PF) purkinge fibers
receives unoxygenated \blood from the superior vena cava and inferior vena cava. RA right atrium
receives unoxygenated blood from the right atrium and pumped out to the lungs through the pulmonary artery RV right ventricle
the thin walled chamber that receives fresh oxygenated blood from the lungs through the four pulmonary veins LA left atrium
receives oxygenated blood from the left atrium and the thickest of all chambers because it has to send blood to the entire body LV left ventricle
what are the four heart valves TV, BV, RSV and LSV;tricuspid valve, bicuspid or mitral valve, right semilunar valve and left semilunar valve
located between the right ventricle and pulmonary artery right semilunar valve
located between the left ventricle and aorta left semilunar valve
what supplies blood to the myocardium coronary artery
contraction of the heart muscle systole
relaxation of the heart muscle diastole
occurs if valves do not close properly murmur
it shows the electrical activity of the heart EKG or electrocardiogram
located in the upper posterior wall of the right atrium; it is the pacemaker of the heart; where the electrical signal originates Sinoatrial node (SA)
electrical signal cardia impulse
located in the right and left atrium; transmit the cardiac impulse atrial conducting fibers
receives the cardiac impulse from the SA node; located at the floor of the right atrium near the interatrial septum; it slows the cardiac impulse down and moves it into the Bundel of His Atrioventricular Node (AV Node)
special conduction tissue located in the interventricular septum; it receives the SLOWED cardiac impulse from the AV node and transmits the impulse Bundle of HIS
branches extend into the Purkinge transmitting the cardiac impulse Bundle branches
long fibers that extend into the ventricular myocardium; transmit cardiac impulse rapidly through the RV and LV to ensure a strong, simultaneous ventricular contraction Purkinge Fibers
number of times the heart beats per minute heart rate
controls the accelerator center and the inhibitory center via the autonomic nervous system medula oblangata
amount of blood by a ventricle in 1 minute cardiac output
the amount of blood pumped by a ventricle per beat; stroke volume
average Stroke Volume is 60 to 80 ml per beat
subdivision of Systemic Circulation in which the blood from the abdominal digestive organs and spleen circulates through the liver before returning to the heart hepatic circulation
what are the functions of purkinge fibers it transmit electrical signals throughout the ventricles
noise closing of the heart valve ; myocardial contraction lub dupp
what opens when pressure on the right ventricles exceeds the pressure with in the pulmonary artery pulmonary valve
it contains a series of actin, myosin and inercalated disc that connects all muscle cells with in myorcardium

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
