Heart
Blood vessels
Blood
What makes up the blood vessels
Arteries, veins and capillaries
Where is the heart located
In the mediastinum within its own cavity
Where is the ventral mediastinum
Between ribs 3-7; almost entirely surrounded by lungs
Cardiac notch
Area on the right side exposed to chest wall( no lungs surrounding)
Pericardial sac in cattle
Is in contact w/touches the diaphragm
Base
The wider part of the heart toward the top/more cranial
Apex
Pointier part of the heart towards the bottom;consists mostly of the left ventricle
Fibrous pericardium
Separated from visceral pericardium by a space
Visceral pericardium
Epicardium
3 layers of the heart wall
Epicardium-outermost layer
Myocardium-the heart muscle itself
Endocardium-inner most layer; lines the chamber walls
Grooves
Coronary groove
Interventricular groove
Coronary groove
Groove around the base of the heart to superficially separate the two atria from the two ventricles
Interventricular groove
Comes down from the coronary groove at an angle to superficially separate the two ventricles
