Anatomy 2 Exam 3 Flashcards
Upper right chamber, most important in embalming to establish and maintain drainage. Low in oxygen blood
RIGHT ATRIUM (RA)
upper left chamber, receives blood from lungs
LEFT ATRIUM (LA)
lower right chamber, pumping unoxygenated blood to the lungs to pick up oxygen
RIGHT VENTRICLE (RV)
lower left chamber, largest and strongest muscle, last pump of blood with oxygen to the body via arteries
LEFT VENTRICLE (LV)
venus side, blood low in oxygen
RIGHT SIDE
artery side, blood high in oxygen
LEFT SIDE
echo cardio gram, used to view/measure heart rhythm
EKG
contraction of ventricle/lower chambers at same time; the contraction phase of the cardiac cycle; No more than 150
SYSTOLIC
resting phase of cardiac cycle. Contraction of atrium/upper chambers of heart at same time; No more than 100
DIASTOLE
all four chambers beating at the same time
TACKY HEART RYTHUM
the space around lungs which houses heart and great blood vessels
MEDIASTINUM
plural/single – single or two upper chambers of the human heart
ATRIA/ATRIUM
the oval shaped opening naturally present between the atria of fetal heart to bypass lungs and allow to develop
FORAMEN OVALE
oval shaped shallow depression from foramen ovale closing itself naturally immediately following birth, best seen in right atria of adult heart.
FOSSA OVALE
single or two lower chambers of the human heart
VENTRICLES
finger like muscles only found in ventral of heart; regulate & control specific heart valves
small bundles of muscles attached to the ventricle walls and to the chordae tendineae that tighten these tendons during ventricular contraction.
PAPILLARY MUSCLES
tendons cords which attach papillae muscles to individual sections/cusps of heart valve they control cusps; 4 individual section of heart valves
they attach papillary muscle to the individual sections or cusp with what they control
CHORDAE TENDINEA
Layers of heart in walls:
ENDOCARDIUM
MYOCARDIUM
PERICARDIUM
innermost layer of heart; layer that makes up cusps of heart valve; layer where valves or cusps are made
ENDOCARDIUM
muscle layer of the heart (MI or myocardial infarction is death of heart muscle) left ventricle is MOST muscular part of the heart (systolic)
MYOCARDIUM
the sac of fluid surrounding the heart
PERICARDIUM
a. viceral
b. parietal
(EPICARDIUM) – part of pericardium that
actually touches or in direct contact with heart
VICERAL
outer layer of pericardium that is
furthest from direct contact with heart
PARIETAL
