Anatomy lesson

“The cardiovascular system is composed by the heart and by the blood vessels in which the blood flows continuously. The heart is the pump that gives the blood the thrust to flow inside the blood vessels. The blood vessels are like tubes of different diameters, used by the blood to reach cells and tissues; they can be divided into arteries that lead the blood from the heart to the rest of the body and into veins that bring back the blood to the heart. Between them the capillaries.

The heart is the central part of the whole system. Its contractions are the reason of the blood flow. It is placed close to the anterior wall of the thorax, right behind the sternum. It is inside the pericardial cavity, between the pulmonary pleurae, inside of the mediastinum. It is not perfectly centered, if we consider the body’s simmetry plan. It is for 2/3 of its volume in the left portion of the body and for 1/3 on the right portion. Its shape is a truncated cone with the base on the top and the apex on the botto,. It lies between the 3rd and the 6th intercostal space. It is an hollow organ composed of two atria and two ventricules. It can also be subdivided into the right and the left heart. between the atrium and its ventricule there’s a cusp valve; between the ventricle and the circulation there’s a semilunar valve. Valves prevent the reflux of the blood.
The heart is wrapped by the pericardium divided into two layers: one is in contact with the surrounding organs, the other directly touches the heart. In between the the pericardial cavity filled by a lubricant fluit which prevents friction during the heart movements.
The heart wall is divided into the epicardium, made by mesothelium and connective tissue; the myocardium, composed of heart muscles cells, vessels, connective tissue and nerves; the endocardium as a single layer of endothelial cells…”

I usually don’t do “lightning remakes” but here’s a better version of the previous post with improved heart animation and sound!!

A friend of yours gives you the opportunity to record her heartbeat after a lap around the running track, ran at the maximum speed she’s able to go, for a scientific project.

You use a stetho-microphone to record the sound of her pump at work and the belt of her HR monitor is perfect to hold it.

After such an effort, her very strong and fit heart is beating very close to 190 bpm and sounds like a methronome.

Just a curiosity: the heart tends to become more spherical under intense phisical efforts.
