Exercise 30 and 31

location of the heart in the thorax

mediastinum

superior heart chambers

atria

inferior heart chambers

ventricles

visceral pericardium

epicardium

anterooms of the heart

atria

equals cardiac muscle

myocardium

provides nutrient blood to heart muscle

coronary arteries

lining of the heart chambers

endocardium

actual "pumps" of the heart

ventricles

drains blood into the right atrium

coronary sinus

right atrium and left atrium

Right-G, Left-R

right ventricle and left ventricle

Right-J, Left-U

Superior and Inferior vena cava

Superior-B, Inferior-K

Ascending aorta

D

Aortic arch

N

Brachiocephalic artery

A

Left common carotid artery

L

Left subclavian artery

M

Pulmonary trunk

E

Right and Left pulmonary arteries

Right-C, Left-P

Ligamentum arteriosum

O

Right and left pulmonary veins

Right-F, Left-Q

Right and left coronary arteries

Right-H, Left-T

Anterior cardiac vein

I

Circumflex artery

S

Anterior interventricular artery

W

Apex of the heart

X

Great cardiac vein

V

3)......to the_____________________, to the capillary beds of the lungs.......

Right and left pulmonary arteries

4).......to the____________, to the _____________of the heart......

pulmonary veins, left atrium

5)....through the______________valve to the___________ through the ____________valve to the__________..........

mitrallbiscupid, left ventricle, aortic semilunar, aorta

6).......to the____________of the tissues, to the systematic veins to the ______________, ____________, and the ________________entering the right atrium of the heart.

capillary beds, inferior vena cava, superior vena cava, coronary sinus.

List the elements of the intrinsic conduction system in order starting from the SA node.

AV node----AV bundle----bundle branches----Purkinje fibers

Desribe what happens in the cardiac cycle immediately before the P wave

heart is in diastole

Desribe what happens in the cardiac cycle during the P wave

depolarization of the atria

Desribe what happens in the cardiac cycle immediately after the P wave (P-R segment)

contraction of thecycles

Desribe what happens in the cardiac cycle during the QRS wave

depolarization of ventricles

Desribe what happens in the cardiac cycle immediately after the QRS wave (S-T interval)

contraction of ventricles

Desribe what happens in the cardiac cycle during the T-wave

repolarization of ventricles

Tachycardia

heart rate over 100 beats per minute

Bradycardia

heart rate below 60 beats per minute

Fibrillation

rapid, uncoordinated heart contractions that makes the heart useless as a pump.

Foramen Ovale (Fetal)

Fossa Ovalis (Adult)

Ductus Arteriosus (Fetal)

Ligamentum Arteriosum (Adult)
