1
blunt rounded point of heart
apex
2
larger flat part
base
3
located in
thoracic cavity
4
formed by the pericardium
pericardial caivty
5
anchors heart within mediastinum
pericardial cavity
6
2 layers of pericardium
fibrous and serous
7
tissue that surrounds the heart
pericardium
8
tough fibrous outer layer of CT
layer of pericardium
fibrous
9
inner layer of epithelial cells
layer of pericardium
serous
10
portion of the serous pericardium lining the fibrous pericardium
Parietal pericardium –
11
portion covering the heart
Visceral pericardium or Epicardium –
12
– produced by serous pericardium
-helps reduce friction as the heart moves within the pericardium
pericardial fluid
13
separates atria from ventricles
Coronary sulcus –
14
grooves which indicate the division between right and left ventricles
Anterior and posterior interventricular sulcus –
15
Veins carrying blood to the heart
superior and inferior vena cava
pulmonary veins
16
Arteries carrying blood away from the heart
aorta and pulmonary trunj
17
-receive blood from veins
-primarily function as reservoirs
-contraction of the__ forces blood into the ventricles
atria
18
Right atrium receives blood through 3 major openings:
SVC, IVC, Coronary sinus
19
Left atrium receives blood through
pulmonary veins
20
partition separating the two atria
Interatrial septum –
21
– pumps blood into pulmonary trunk
right ventricle
22
pumps blood into aorta
left ventricle
23
- partition separating the two ventricles
Interventricular septum
24
between right atrium and right ventricle and between left atrium and left ventricle
-allow blood to flow from the atria
Atrioventricular valves –
25
cone-shaped, muscular pillars in each ventricle
Papillary muscles –
26
– three, pocketlike semilunar cusps
-possessed by aorta and pulmonary trunk
semilunar valves
27
– plate of CT
-consists of fibrous rings that surround the AV and semilunar valves
cardiac skeleton
28
– supply blood to the wall of the heart
-originate from the base of the aorta
coronary arteries
29
3 Major Branches of left coronary artery
1. Anterior interventricular artery
2. Circumflex artery
3. Left marginal artery
