THE HEART AND GREAT VESSELS Flashcards
WHERE DOES THE HEART LIE
MAINLY BEHIND THE STERNUM BUT PROTRUDES INTO THE LEFT HAND SIDE
WHAT ARE THE ANATOMICAL LANDMARKS FOR THE CORNERS OF THE HEART
RA - 3RD COSTAL CARTILAGE
RV - 6TH COSTAL CARTILAGE
LA - 2ND COSTAL CARTILAGE
LV - 5TH INTERCOSTAL SPACE
WHY ARE THE FOUR CORNERS OF THE HEART CLINICALLY IMPORTANT
DIAGNOSING HEART DEFECTS
WHERE DOES THE RIGHT CORONARY ARTERY ORIGINATE
THE BASE OF THE AORTA
THE ATRIA HAVE ……………….. APPENDAGES ATTACHED TO THEM
AURICULAR
WHAT ARE THE VALVES OF THE HEART
TRICUSPID
BICUSPID (MITRAL)
AORTIC
PULMONARY
HOW MANY SHUNTS ARE IN FOETAL CIRCULATION
3
WHAT ARE THE THREE SHUNTS OF FOETAL CIRCULATION
DUCTUS ARTERIOSUS
FORAMEN OVALE
DUCTUS VENOSUS
EXPLAIN THE FUNCTION OF THE DUCTUS ARTERIOSUS
LUNG BYPASS - A DUCT BETWEEN THE PLUMONARY ARTERIES AND THE AORTA
ALLOWS O2 RICH BLOOD TO BYPASS THE LUNGS
THE RV PUSHES BLOOD INTO THE AORTA INSTEAD OF THE LUNGS
EXPLAIN THE FUNCTION OF THE FORAMEN OVALE
ANOTHER BYPASS OF THE LUNGS BETWEEN RIGHT AND LEFT ATRIA ALLOWING OXYGENATED BLOOD TO FLOW
WHAT IS THE FUNCTION OF THE DUCTUS VENOSUS
LIVER BYPASS
FORM A SHUNT BETWEEN THE UMBILICAL VEIN AND THE INFERIOR VENA CAVA THEREBY BYPASSING THE LIVER
THE OBLIQUE SINUS FORM AN …… SHAPED SPACE MARKED BY THE PULMONARY …………………
THE TRANSVERSE SINUS RUNS BEHIND THE …………….. AND PULMONARY ARTERIES IN A WAY THAT ………………….. THE ARTERIES FROM THE VEINS
ARTERIES
AORTA
SEPARATES
THE SUPERIOR VENA CAVA SPLITS INTO THE …………………………….. VEINS. THE LEFT BRACHIOCEPHALIC VEIN CROSSES THE ………… OF THE AORTA TO CROSS THE BODY. THE BRACHIOCEPHALIC VEINS SPLIT INTO …………………………… , EXTERNAL AND INTERNAL …………………… VEINS.
BRACHIOCEPHALIC
ARCH
SUBCLAVIAN
JUGULAR
WHAT DOES THE DUCTUS ARTERIOSUM BECOME
LIGAMENTUM ARTERIOSUM
WHAT DOES THE DUCTUS VENOSUM BECOME
LIGAMENTUM VENOSUM
WHAT DOES THE FORMAMEN OVALE
FOSSA OVALIS
WHAT IS THE CORONARY SINUS
COLLECTION OF VENOUS VESSELS MERGING TO FORM A LARGE VESSEL THAT OPENS INTO THE RIGHT ATRIUM
WHAT ARE THE PAPILLARY MUSCLES
THEY CONTRACT TO MAKE SURE THE ATRIOVENTRICULAR VALVES ARE CLOSED
THE ARE IN THE WALLS OF THE VENTRICLES ATTACHED TO THE CHORDAE TENDINAE
WHAT IS A MODERATOR BAND
A LARGE BAND THAT CARRIES ELECTRICAL SIGNALS
WHAT ARE TRABECULAE CARNAE
MUSCULAR ELEVATIONS THAT FORM THE INNER SURFACE OF THE VENTRICLES
WHAT ARE CHORDAE TENDINAE
THE ‘HEART STRINGS’ THAT HOLD THE AV VALES IN PLACE
WHAT ARE PECTINATE MUSCLES
THE MUSCULAR TEXTURED RIDGES LINING THE ATRIA
WHAT IS CRISTAE TERMINALIS
THE SMOOTH SURFACE OF THICK MUSCLE IN THE ATRIA
WHAT BRANCHES DOES THE RIGHT CORONARY ARTERY SPLIT INTO
RIGHT MARGINAL
POSTERIOR INTERVENTRICULAR
WHAT BRANCHES DOES THE LEFT CORONARY ARTERY BRANCH INTO
LEFT CIRCUMFLEX
ANTERIOR INTERVENTRICULAR
WHAT IS RIGHT DOMINANCE
THE ARTERY SUPPLYING THE POSTERIOR OF THE HEART COMES FROM A BRANCH OF THE RIGHT CORONARY ARTERY
WHAT IS LEFT DOMINANCE
THE ARTERY SUPPLYING THE POSTERIOR OF THE HEART COMES FROM A BRANCH OF THE LEFT CORONARY ARTERY
WHAT IS THE DANGER OF LEFT DOMINANCE
IF THE LEFT CORONARY ARTERY AND ITS BRANCHES ARE SUPPLYING THE MADE BLOODY SUPPLY FOR BOTH ANTERIOR AND POSTERIOR SIDES THEN A BLOCKAGE WOULD AFFECT A GREATER PORTION OF THE HEART WOULD BE AFFECTED IF THERE WAS A BLOCKAGE
THE BASE OF THE HEART IS FORMED MAINLY BY THE
LEFT ATRIUM
THE APEX OF THE HEART IS FORMED MAINLY BY THE
LEFT VENTRICLE
WHAT ARE AORTIC SINUSES
SMALL OPENINGS FOUND BEHIND THE FLAPS OF THE AORTIC VALVE
WHAT ARE THE FIVE TRIBUTARIES THAT DRAIN INTO THE CORONARY SINUS
THE GREAT CARDIAC VEIN SMALL CARDIAC VEIN LEFT MARGINAL VEIN LEFT POSTERIOR VENTRICULAR VEIN MIDDLE CARDIAC VEIN
WHERE IS THE CORONARY SINUS LOCATED
ALONG THE POSTERIOR CORONARY SULCUS
THE SINOATRIAL NODE IS LOCATED WHERE
IN THE UPPER WALL OF THE RIGHT ATRIUM NEAR THE OPENING OF THE CORONARY SINUS
THE ATRIOVENTRICULAR NODE IS LOCATED WHERE
IN THE ATRIOVENTRICULAR SEPTUM
