The massive ventricle can lead to a heart weighing over 1000 grams (the weight of a normal heart is about 350 grams), referred to as cor bovinum (Latin for cow's heart). [1] Fluri and Gebbers [2] define cor bovinum as a heart exceeding 500 g in weight. Looking through autopsies on Internal Medicine patients at the Kantonsspital Luzern, they ...
The chordae tendineae (sg.: chorda tendinea) or tendinous cords, colloquially known as the heart strings, are inelastic cords of fibrous connective tissue that connect the papillary muscles to the tricuspid valve and the mitral valve in the heart.
Reticulum beef tripe. The internal mucosa has a honeycomb shape. When looking at the reticulum with ultrasonography it is a crescent-shaped structure with a smooth contour. [2] The reticulum is adjacent to the diaphragm, lungs, abomasum, rumen and liver.
Tissue heart valves are usually made from animal tissue (heterografts) mounted on a metal or polymer support. [14] Bovine (cow) tissue is most commonly used, but some are made from porcine (pig) tissue. [15] The tissue is treated to prevent rejection and calcification (where calcium builds up on the replacement valve and stops it working ...
The heart is a muscular organ found in humans and other animals. This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [3]
The heart's cardiac skeleton comprises four dense connective tissue rings that encircle the mitral and tricuspid atrioventricular (AV) canals and extend to the origins of the pulmonary trunk and aorta. This provides crucial support and structure to the heart while also serving to electrically isolate the atria from the ventricles. [1]

For mother cows to continue producing milk, they give birth to one calf per year. If the calf is male, it is generally slaughtered at a young age to produce veal. [106] Cows produce milk until three weeks before birth. [103] Over the last fifty years, dairy farming has become more intensive to increase the yield of milk produced by each cow.
