Order that blood pass through from the vena cava to the systematic circulation |
Vena Cava R. Atrium Tricuspid Valve R.Ventricle Pulmonary Valve Pulmonary artery Pulmonary capillaries Pulmonary Vein L.Atrium Mitral Valve L. Ventricle Aortic Valve Aorta Systematic Capillaries Systematic veins |
|
|
Apex |
pointed, free-end, directed caudally and ventrally |
|
|
Base of the heart |
directed cranially and dorsally continuous with large arteries and veins |
|
|
3 layers of the heart wall |
1. Epicardium: visceral pericardium 2. Myocardium: thick muscular layer -Cardiac muscle= striated, branching 3. Endocardium: endothelial layer |
|
|
names of the right/left A-V & semilunar valves |
Atria: receive blood from large veins Ventricles: receive blood from the atria (pumps blood away from the heart) |
|
|
Atrioventricular (A-V) valves |
-between the atria and ventricles -prevent back flow of ventricular blood into the atria -chordae tendinae and papillary muscles |
|
|
Left A-V valve |
Mitral valve 2 flaps |
|
|
Right A-V valve |
ticuspid valve 3 flaps (in most animals, dogs only have 2) angular, parietal and septal |
|
|
Semilunar valves |
valves between the ventricles and the large arteries |
|
|
Left semilunar valve |
aortic valve located below the aorta |
|
|
right semilunar valve |
pulmonic valve located below the pulmonary trunk |
|
|
define the structures of the heart |
? |
|
|
3 layers of the arterial walls |
? |
|
|
know the arterioles, capillaries, veins, and venues |
arterioles: small arteries, muscle is reduced to just a few layers capillaries: narrow tubes lined by endothelial cells, fluid passes through them from the blood into the interstitial tissue, sinusoids are special capillaries found in certain organs (live, spleen, bone marrow) wider less regular and more commonly fenestrated |
|
|
different types of cells found in the blood |
red blood cells |
