Cow heart anatomy. Note the amount of fatty material lightwhite colored tissue covering the surface of the heart. These tendons hold the heart valves in place sometimes they are called the heartstrings. Only the ventricles are visible in this photo.
Below is a diagram of the anatomy of a cow. This photo shows the adult cow heart cut in cross section through the ventricles with the smaller right ventricle at top and the larger left ventricle at the bottom. Consequently the left ventricle works harder than the right ventricle to maintain the same blood flow rate.
About pictured here is a cow heart with some incisions to show the chambers and valves inside. Chambers of the heart. The muscular wall of the left ventricle being significantly thicker than that of the right.
This difference in workload affects the anatomy of the ventricular walls. Dissection of a fresh cow heart. Cows have 32 teeth in all 8 incisors on the bottom part and 6 molars on the top and bottom parts on each side.
What side of the heart is thicker than the other side. A cows mouth is adapted for grazing the top part of the mouth is a hard pad and the bottom part a row of flat topped teeth. The valves were probably cut when the heart was opened but if you follow the cords they should lead you to a thin flap that is the atrioventricular bicuspid valve.
We will explore the cow heart because its larger size makes it easier to see the important and complex structures of the heart. The two are separated by the interventricular septum and this example shows that the left ventricles walls are much thicker and stronger. Left 9 papillary muscle does not show up too well.
A human heart weighs between seven and 15 ounces whereas a cow heart can weight up to five pounds. You can find a similar valve on the right side of the heart tricuspid. Oxygenated blood is brought from the lungs to the heart to be pumped through the body.
Both the cow and human heart serve the same purpose and the function of each heart is virtually identical. Anatomy of the cow heart. They attach to the cusps of the atrioventricular valves also known as the mitral and tricuspid valves via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole or ventricular contraction.
