How the Heart Works

The heart is one of the most important organs of the whole human body. It is really just a pump, the muscle it collects strikes 72 times per minute, pushing blood through the body. The heart delivers blood, delivers all important substances, helps our bodies function and removes unwanted products we do not need. For example, the brain needs oxygen and glucose, if it is not received endlessly, it will make it unconscious of it.

Modern research greatly improves our understanding of how the heart functions and has brought about new therapies for heart disease. However, little is known about how the heart evolved in the history of animals with skeletons - this group is collectively called a vertebrate. This is because the heart is made of soft muscle tissue not calcified like hard tissue like bone. Soft tissue fossils are rare, but paleontologists have excavated other soft tissue fossils such as the stomach and umbilical cord. These findings suggest hope for fossil's heart, and now Lala Maldanis, Murilo Carvalho and colleagues have certainly found a fossil heart with two extinct teleost fish known as Rhacolepis buccalis . These fish are still living in the Cretaceous age 113 million years ago and are now in modern Brazilian regions.

Soft heart. The spongy shape that we feel in the heart is because the muscle tissue is filled with air and liquid. If you like technical terms, it is also called emphysema or infectious disease. From the test results, it was confirmed that Clostridium bacteria proliferated intramuscularly, causing inflammation (myocarditis) and heart failure. Unlike gas generating capsules, which are usually taken up as active bacteria, nocorat is ingested as spores, circulated and deposited in the tissues and remains inactive until hypoxia germinates and proliferates. C. The existence of Novi is usually related to "dark diseases" of livestock sheep and cows. Parasites can cause rapid bacterial growth and damage the liver.
