Dinosaur Physiology and the Doubtful Four Chambered Heart Discovery

Physiological functions of dinosaurs and suspicious four-cavity findings In recent years, there was evidence of some cardiovascular that dinosaurs are generally considered to be too hot. I found a skeleton wrapped in sandstone. It is very similar to a skeleton similar to Thescelosaurus. This bone set has a heart-shaped rock in the chest. A test is in progress to determine if the heart is actually the recommended 4 hearts. If so, the physiological theory of dinosaurs may change drastically.

Considering that the upright posture of some large dinosaurs and the vertical distance between the heart and the head requires high blood pressure like giraffe. It needs 4 rooms to separate high pressure blood into the body and separate it from the low pressure blood into the lungs. Hypothesis: The quadrant core is a feature of endotherm and requires high blood flow velocity and high body blood pressure. After evolutionary heat absorption and such a heart, dinosaurs can evolve into larger size and upright attitude. Problem: In addition to the warm crocodile quadrangle, this assumption has never been rebutted.

Humans, birds and mammals have a heart with four hearts. This fish has a heart, atrium and ventricle consisting of two rooms. Amphibians have three chambers of the heart with two atria and one ventricle. The advantage of a four-chamber heart is that there is no mixing of oxygenated blood and deoxygenated blood. Human cardiovascular system includes lung and whole body circulatory system. The pulmonary circulatory system consists of blood vessels that carry deoxygenated blood from the heart to the lungs and carry oxygen-containing blood from the lungs to the heart. In the systemic circulatory system, blood vessels transport oxygenated blood from the heart to various organs of the body and deliver deoxygenated blood to the heart.

Tracing blood flowing through the heart is not as simple as it seems. The heart is a complex organ that uses four chambers, four valves, and multiple vessels to supply blood to the body. The flow through the heart is equally complex, blood passes through the heart, then the lungs move, and then returns to the heart again. Blood first enters the right atrium. It then enters the right ventricle through the tricuspid valve. When the heart beats, the ventricle sends blood through the pulmonary valve to the pulmonary artery. This artery is unique: it is the only artery in the body to carry hypoxic blood.
