The circulatory system begins to form very early during embryonic development, just a few days after the fertilization of the egg by the sperm. It is the first functional system to develop, as it is crucial for delivering the nutrients and oxygen required for the embryo’s rapid growth. This early formation is a complex and fascinating process that marks the initial stages of life.
When the heart rate drops below 60 beats per minute, it is referred to as bradycardia. This slower rate can be a natural response or, in some cases, a sign of a rhythm disorder.
When the heart rate exceeds 100 beats per minute, this is referred to as tachycardia. A rapid rhythm may be a natural response or a sign of arrhythmia.
A heart murmur is a sound heard when listening to the heart with a stethoscope. It results from the turbulence of bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood flow through the heart’s valves, causing the surrounding walls to vibrate, which produces this characteristic sound.
The heart is an almost indefatigable muscular organ. It is located in the center of the thorax.
From the 14th day of fetal life, the heart begins its work. From then on, it is the central engine of bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood circulation throughout the body.
In our body, bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure is what makes oxygenated bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood travel through the arteries. BloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood is propelled from the heart to the organs (brain, kidneys, digestive tract, muscles), then the bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood returns through the veins to be reoxygenated by the lungs.
This site is intended to provide information and make cardiology comprehensible for all patients; it is not a substitute for a doctor. It does, however, enable a better understanding of how the heart works, the many heart diseases that exist, the tests required to reach a diagnosis, and the drugs and other methods used to treat them.
