1

WHERE DOES THE HEART LIE

MAINLY BEHIND THE STERNUM BUT PROTRUDES INTO THE LEFT HAND SIDE

2

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

3

WHY ARE THE FOUR CORNERS OF THE HEART CLINICALLY IMPORTANT

DIAGNOSING HEART DEFECTS

4

WHERE DOES THE RIGHT CORONARY ARTERY ORIGINATE

THE BASE OF THE AORTA

5

THE ATRIA HAVE .................... APPENDAGES ATTACHED TO THEM

AURICULAR

6

WHAT ARE THE VALVES OF THE HEART

TRICUSPID
BICUSPID (MITRAL)
AORTIC
PULMONARY

7

HOW MANY SHUNTS ARE IN FOETAL CIRCULATION

3

8

WHAT ARE THE THREE SHUNTS OF FOETAL CIRCULATION

DUCTUS ARTERIOSUS
FORAMEN OVALE
DUCTUS VENOSUS

9

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

10

EXPLAIN THE FUNCTION OF THE FORAMEN OVALE

ANOTHER BYPASS OF THE LUNGS BETWEEN RIGHT AND LEFT ATRIA ALLOWING OXYGENATED BLOOD TO FLOW

11

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

12

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

13

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

14

WHAT DOES THE DUCTUS ARTERIOSUM BECOME

LIGAMENTUM ARTERIOSUM

15

WHAT DOES THE DUCTUS VENOSUM BECOME

LIGAMENTUM VENOSUM

16

WHAT DOES THE FORMAMEN OVALE

FOSSA OVALIS

17

WHAT IS THE CORONARY SINUS

COLLECTION OF VENOUS VESSELS MERGING TO FORM A LARGE VESSEL THAT OPENS INTO THE RIGHT ATRIUM

18

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

19

WHAT IS A MODERATOR BAND

A LARGE BAND THAT CARRIES ELECTRICAL SIGNALS

20

WHAT ARE TRABECULAE CARNAE

MUSCULAR ELEVATIONS THAT FORM THE INNER SURFACE OF THE VENTRICLES

21

WHAT ARE CHORDAE TENDINAE

THE 'HEART STRINGS' THAT HOLD THE AV VALES IN PLACE

22

WHAT ARE PECTINATE MUSCLES

THE MUSCULAR TEXTURED RIDGES LINING THE ATRIA

23

WHAT IS CRISTAE TERMINALIS

THE SMOOTH SURFACE OF THICK MUSCLE IN THE ATRIA

24

WHAT BRANCHES DOES THE RIGHT CORONARY ARTERY SPLIT INTO

RIGHT MARGINAL
POSTERIOR INTERVENTRICULAR

25

WHAT BRANCHES DOES THE LEFT CORONARY ARTERY BRANCH INTO

LEFT CIRCUMFLEX
ANTERIOR INTERVENTRICULAR

26

WHAT IS RIGHT DOMINANCE

THE ARTERY SUPPLYING THE POSTERIOR OF THE HEART COMES FROM A BRANCH OF THE RIGHT CORONARY ARTERY

27

WHAT IS LEFT DOMINANCE

THE ARTERY SUPPLYING THE POSTERIOR OF THE HEART COMES FROM A BRANCH OF THE LEFT CORONARY ARTERY

28

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

29

THE BASE OF THE HEART IS FORMED MAINLY BY THE

LEFT ATRIUM

30

THE APEX OF THE HEART IS FORMED MAINLY BY THE

LEFT VENTRICLE
