where the heart sit. obliquely within the thoracic cavity between the lungs and above the diaphragm.

Question 7

what are the 3 layers of the heart?

Answer 7

epicardium,-outer layer is anatomically identical to the visceral pericardium.

myocardium, -is the thick, muscular layer, is made up of bundles of cardiac muscle fibers reinforced by a branching network of connective tissue fibers called the fibrous skeleton of the heart.

endocardium,-inner most layer a smooth layer that provides an inner lining for the chambers of the heart.

Question 8

4 chambers of the heart

Answer 8

two smaller superior chambers called atria

two larger inferior called ventricles.

Question 9

right and left atrium

Answer 9

receiving chambers for blood returning to the heart from the major blood vessels of the body.

Question 10

Apex

Answer 11

Valves that separate the atria from the ventricles within the heart
Tricuspid
mitral

Question 12

Systole / Diastole

Answer 12

S-The phase of ventricular contraction in which the ventricles have been filled, then contract to expel blood into the aorta and pulmonary arteries. This is also associated with the top number of a blood pressure reading

D-The phase of ventricular relaxation in which the ventricles relax and are filled as the atria contract. This is also associated with the bottom number of a blood pressure reading

Question 13

NVD (neck vein distention)

Answer 14

the jugular vein protrudes from the side of your neck

Question 15

S1 S2 S3 S4

Answer 15

S1-The first heart sound (lub) is heard when the AV valves close. Closure of these valves occurs when the ventricles have been filled
S2-The second heart sound (dub) occurs when the aortic and pulmonic valves close, they close when the ventricles have emptied their blood into the aorta and pulmonary arteries
S3-ventricular gallop, when the AV open, blood flow into the ventricles may cause vibrations. during diastole
S4-caused by atrial contraction and ejection of the blood into the ventricle in late diastole atrial gallop

Question 16

AV node (Atrioventricular)

Answer 16

Node, located in the wall of the right atrium, capable of initiating electrical impulses in the event of SA node failure; intricately connected to the bundle of His

Question 17

SA node (sinoatrial)

Answer 17

The node located at the junction of the superior vena cava and right atrium that initiates the electrical impulse. PACE MAKER OF THE HEART.

Question 18

Heart murmurs

Answer 18

harsh, blowing sounds caused by disruption of blood flow into the heart, between the chambers of the heart, or from the heart into the pulmonary or aortic systems.

Question 19

Bundle of his, bundle branches, purkinjue fibers

Answer 19

Bundle of his- Nodes that are intricately connected and function to receive the current that has finished spreading throughout the atria
Bundle branches-Expressways of conducting fibers that spread the electrical current through the ventricular myocardial tissue.
Purkinjue fibers-Fibers that fan out and penetrate into the myocardial tissue to spread the current into the tissues themselves

Question 20

Atria, Ventricles

Answer 20

chambers of the heart that receive and eject blood

Question 21

Sternum, clavicles, xyphoid process

Answer 21

Sternum- The flat, narrow center bone of the upper anterior chest.
Clavicles- collarbone is a long bone that serves as a strut between the scapula and the sternum. It is the only long bone in the body that lies horizontally. It makes up part of the shoulder and the pectoral girdle, and is palpable in all people; in people who have less fat in this region, the location of the bone is clearly visible, as it creates a bulge in the skin
Xyphoid process-metasternum, is a small cartilaginous process (extension) of the lower part of the sternum which is usually ossified in the adult human

Question 22

Cardiac cycle

Answer 22

describes the events of one complete heartbeat- that is, the contraction and relaxation of the atria and ventricles.

Question 23

ECG

Answer 23

Electrical representations of the cardiac cycle are documented by deflections on recording paper

Question 24

Stroke volume

Answer 24

The amount of blood that is ejected with every heartbeat

Question 25

cardiac output

Answer 25

The amount of blood ejected from the left ventricle over 1 minute

Question 26

Preload / afterload

Answer 26

preload- the amount of blood and stretching of the ventricular myocardial fibers. Afterload- the pressure that ventricles must overcome in order to open the aortic pulmonic valvular cusps.

Question 27

epicardium

Answer 27

The outer layer of the heart wall that is also called the visceral pericardium

Question 28

Semicircular valves

Answer 28

Valves that separate the ventricles from the vascular system pulmonary aortic

Question 29

Splinter hemorrhage

Answer 29

red lines in the nail beds associated with infective endocarditis, a condition caused by bacterial infiltration of the lining of the heart's chambers. (smooking)
