The Organ We Love - How The Heart Works

Being the strongest muscle in the torso, the minds purpose is to pump blood through our blood vessels through rhythmic contractions. The center secrets "ANF which is really a very effective peptide hormone, to regulate volume and blood pressure. It influences the regulatory region of the head, in addition to the adrenal glands, blood vessels, and the kidneys.
To start, i would like to clean up an internationally rumor; the Heart is not located on the left side of one's body! Its precise site is found in the heart of your chest, just SLIGHTLY of to the left hand side, and underneath the sternum. For security, the heart is enveloped in a named the pericardium, and is surrounded by the lungs. First thought is, "why does the strongest muscle in the body need therefore much protection?" .

Weighing in at about 300 grams, one's heart includes 2 top atria and 4 chambers; 2 decrease ventricles. Valves between the ventricle and the atrium control proper blood circulation in one to the other.
The work of pumping blood everywhere in the body is just a big responsibilty. Each and every defeat of the heart is made up of sequence of events called the cardiac cycle. "Cardiac" is traditional, indicating "heart." There is 3 significant steps in the sequence: atrial systole, ventricular systole and total cardiac diastole. Following the body has completely left the atria, the atrioventricular valves (situated between atria and ventricular chambers), close to prevent backflow. This function is what you would recognize as your pulse. Next, there's a of the ventricles and flow of blood in to the circulatory system. This is known as the ventricular systole. Once again, valves called "pulmonary" and "aortic semilunar" close to prevent backflow. After these 2 measures, the center takes a quick break called complete cardiac diastole. This allows the refilling of body and to begin the procedure over.
