How Does the Human Heart Work

How your heart works!


The human heart is one of the hardest working organs in the body. On average it beats 72 times a minute as the heartbeats it provides pressure. So blood can deliver oxygen, an important nutrients to tissue all over your body through an extensive network of arteries, in fact, the heart steadily pumps an average of 2000 gallons of blood through the body each day.

Your heart is located underneath your ribs and between your two lungs, the hearts parts, the hearts for chambers function as a double sided pump, the right side of the heartaches in oxygen, depleted blood from the organs this blood is delivered to the heart through the veins, the Chambers on the left side pump oxygen, rich blood out to the body through arteries, the hearts for chambers all are right. Atrium, this chamber receives oxygen, depleted blood that has already circulated around the body and pumps into the right, ventricle right, ventricle, the right ventricle pumps, blood from the right atrium to the pulmonary artery.

The pulmonary artery sense that the oxygenated blood to the lungs, where it picks up oxygen, left atrium. This chamber receives oxygenated blood from the lungs and pumps it to the left. Ventricle left ventricle, the thickest of all the chamber's. The left ventricle is the hardest working part of the hard as it pumps blood throughout the whole body. The hearts 28 trea are both located on the top of the heart.

They are responsible for receiving blood from your veins. The hearts two ventricles car located in the bottom of the heart they are responsible for pumping blood into your arteries, your atria and ventricles contract to make your heartbeat and to pump the blood through each chamber. Your heart fills up with blood before each beat and the contraction pushes the blood out into the next chamber.

The contractions are triggered by a lack trickle pulses that start from the sinus node or sin note real node son owed located in the wall of your right. Atrium, the pulses then travel to your heart to the at Rea, ventricular, node or avenue node located near the center of the heart between the Kate Rea and the ventricles. These electrical impulses keep your blood flowing in proper rhythm. The heart has four valves that separate each chamber so that, under normal conditions, blood cannot flow backwards. These valves can sometimes be replaced if they become damaged.

The hearts valves are trite, dusted, right avenue. The health this valve opens to allow blood to flow from the right. Eight tree and to the right ventricle pulmonary valve this valve, opens to allow blood to flow from the heart into the lungs so that it can receive more oxygen. Might roll left avenue the health this valve opens to let blood flow from the left atrium to the left? Ventricle your tip valve this valve opens to let blood leave the heart and be pumped around the body. The hearts crown the structure of the heart's blood supply is called the coronary circulatory system.

The word coronary comes from the Latin word, meaning of a crown the arteries that fuel the hearts muscle encircle the heart. Like a crown coronary heart disease develops when cholesterol plaques collect in the arteries that feed the heart muscle. If a portion of one of these plaques ruptures, it can block one of the vessels and cause the heart muscle to begin to die because it is starved for oxygen and nutrients.

This can also occur if a blood clot forms and one of the arteries of the heart blood flow through the heart when working properly the oxygenated blood coming back from organs enters the heart through two major veins known as the Vina caddie from there. The blood enters the right, atrium and passes through that reich us that valve into the right ventricle.

The blood then flows through the pulmonary valve into the pulmonary trunk and then travels through one of two pulmonary arteries out to the lungs where it receives oxygen. On its way, back from the lungs, the blood travels through four pulmonary veins into the left atrium at the top of the heart.

The blood then flows through the mitral valve into the left. Ventricle, the hearts powerhouse. The blood quickly travels out the left ventricle through the aortic valve and into the ascending a ale, or to a portion of the aorta our tree, extending upward from the heart from there. The blood travels through a maze of arteries to get to every cell in the body.

A-FIB VERSUS JUNCTIONAL RHYTHMS

. ATRIAL FIBRILLATION: On your rhythm strip, the two most important characteristics are: . 1) A rhythm that’s IRREGULARLY irregular (meaning there’s no way to predict the next beat) 2) No discernible P waves . In fact, if you notice an irregularly irregular rhythm and you’re having to convince yourself that you see P waves... it’s probably A-fib (multifocal atrial arrhythmias like WAP/MAT could fit the differential) . *In my opinion: Don’t get caught up in using fibrillation waves as an absolute criteria. Very fine A-fib can sometimes produce a near isoelectric line between beats. . JUNCTIONAL RHYTHMS: The pacemaker cells surrounding the AV junction are capable of initiating regular impulses but at a slightly slower natural rate than their sinus and atrial superiors. The heart is built this way so that when the pacemaker cells with the fastest intrinsic rates are in action, those below are suppressed and function primarily to pass along the impulse from above. . For these reasons, we s...

The Pathway of Blood

Here’s a great illustration on the pathway of blood flow through the heart. It may seem easy...but you should know this cold as well as the cardiac anatomy, both of which will make procedures and understanding hemodynamics easier. . . . đŸ’™VENOUS BLOOD- Blood flows into the heart (into the right atrium) through two major veins (the superior and inferior vena cava) as well as from the coronary sinus (cardiac venous blood from the coronaries) and then out through the first AV valve (tricuspid valve) into the right ventricle. From there blood flows into the right ventricular outflow tract, across the first semilunar valve (pulmonic valve) and into the main and then left and right pulmonary arteries. Blood then enters the lungs to become oxygenated. . . . ❤️ARTERIAL BLOOD- now that blood is oxygenated flow goes from the lungs into the left atrium through 4 veins (usually) called the pulmonary veins. From the left atrium blood flows across the other AV valve (mitral valve) and into the left ...

How to Stop Ectopic Beats

What is Ectopic Beats? According to Dr. Boon Lim - Ectopic beats are also known as Ectopic Heart Rhythm or cardiac ectopy. It is produced when the heart creates a premature beat, usually followed by a brief pause. Types of Ectopic Beats: 1. Premature Ventricular Contraction (PVC) 2. Premature Atrial Contraction (PAC) Causes Of Ectopic Beats There are different causes of Ectopic Beats. Some of these are  Excessive alcohol consumption Excessive caffine consumptionPrescription drugs Stress (which produces high adrenaline levels) Exercise Diarrhoea and vomitting, which may disturb electrolyte levels (typically low potassium levels) Heart muscle damage from a heart attack Heart enlargement (cardiomyopathy) Valvular heart disease, such as a floppy mitral valve (mitral valve prolapse) Symptoms of Ectopic Beats Following Can Be The Symptom of Ectopic Beats: your heart is fluttering you are hyper aware of your heartbeat you feel faint or ...
