3. PART 01
INTRODUCTION
The cardiovascular system is the transportation system of body.
It consist Heart,blood vessels and heart,
The system works to deliver nutrients to the tissue and to remove
waste products from the tissue ,
The conveying media is in liquid form which flows into the
tubular system.

4. Anatomy of Heart
 Location - the heart rests on the diaphargm,near the midline of
thoracic cavity.and generally located in cardiac notch present on
left lung.
 Anatomical Regeion - it extends from sternum to vertebral
column,from the 1st rib to diaphargm, and between the lungs.
 Weight - weighing about 250g in Adult Females,& 300g in Adult
Males.
 Length - It is about 12cm long, and 9cm wide at its broadest
point.
Relation of heart
 Superiorly - the aorta,the SVC,Pulmonary Artey & vein
 Inferiorly - the diaphargm
 Anteriorly - the ribs and the intercostal cartilages & muscles
 Posteriorly - the esophegus,trachea, left and right
bronchus,descending aorta,IVC & thoracic vertebrae.
 Latrally - the lungs

5. Sulci of the Heart
 It is a groove on the outer surface of the heart marking the
division between atria and ventricle
 Atrioventricular Sulcus
 it contains right and left coronary
artery,& coronary Sinus.
 Anterior interventricular sulcus
 lies between the left and right ventricle
on the antiror surface, contain left
anterior descending artery & great
cardiac Vein
 Posterior interventricular sulcus
 lies between the right and left ventricle
contains posterior interventricular artery
& middle cardiac artery.
Auricle Antrior surface of each atrium have a wrinkled
like pouch structure called an Auricle . It is
beause to hold more volume of blood.

6. Coverings of Heart
 Pericardium
 The heart is enclosed with a double layerd of fibro-serous layer or sac called
Pericardium.
 Function:
 Prevent overstreching of Heart,
 Protectuon of Heart,
 Anchors the Heart in Mediastinum

7. Chambers of Heart
 The heart has four chambers , the upper are known as atrium and the lower are
known as ventricles.

8. Heart Valves
 Heart consist four valves........

9. Histology of Artery
 It consist three layers
tunica Intima
tunica Media
tunica Adventitia
Tunica intima made up of endothelium and sub
endothelium tissue
Tunica media is thickest layer and consist ofelastic fibers
Vassovassarum present in tunica adventitia

10. Histology of Vein
it has also three layers,
tunica intima
tunica media
tunica adventitia
these tublar organ consist bigger lumen and thin wall
tunica media consist of smooth muscle fibers
