Different heart capacities
The heart is pumped about 70 centimeters of blood continuously, which is estimated at about 180 million liters throughout the entire period of the heart. In order to know how many pulses a human heart can beat through its average age, we can say that the number of pulses is about 60 to 100 beats per minute. The average pulse is Between two billion and five billion beats in human lifetime. The heart stops to rest between every two consecutive pulses about 0.4 seconds, while the blood vessels transport the length in the human body is close to 140 thousand kilometers and this is a very huge number.
There is a condition known as heart arrhythmia. The heart may experience either a rapid heartbeat or a slow heartbeat. These two conditions may result from many different conditions.
Blood vessels
The arteries and veins are present in the circulatory system within the human body. The arteries are part of the blood vessels in the human body, which transfer the blood from the heart to all parts of the body, as the blood vessels transfer to the lungs blood, which is loaded with carbon dioxide, Through the so-called pulmonary artery, while the transfer of aortic artery blood oxygen-carrying to all parts of the body. The veins are responsible for transferring blood from different parts of the body to the heart, and unlike the arteries; veins from the lungs to the heart are loaded with oxygen, and parts of the body to the heart are loaded with carbon dioxide.
