Blood circulation in heart flowchart is called breaths of life as it is the essential system in the human body. It is the blood supply of the whole body and is responsible for delivering the blood to every organ.

For the utmost efficiency, the heart has to beat more than 100,000 times per day and pump nearly 600 gallons of blood. Let’s look at the diagram below to have a better understanding of the circulation of this organ!

Overview of Blood Circulation In Heart Flowchart

What Is Blood Circulation?

Blood transmission is a repeated cycle in the internal system that transfers blood and oxygen throughout the whole body. The system consists of the heart valves, the blood pulses, and the lymphatic vessels.

It is structured like a big tree; the biggest root is the heart which includes the heart tissues. The root will transport nutrition to the trunk, the major arteries, and then, the "artery trunk" will split the nutrition onto the blood vessels. The supply of blood is one of the most important processes in the human body as it is the main source that nurtures the brain.

The Function Of Blood Circulation

The biggest mission of pulmonary circulation is to distribute the oxygenated blood to every part of the body. The help of the circulation generates our daily activities that evolve muscles or brains. It produces oxygen and nutrients for the operation of external and internal sections. If we do not eat healthy, we may get coronary artery disease and heart attack.

Besides, it also helps filter and eliminates the toxic waste accumulated in the body. The waste may come from respiration or the food and drink we digest.

What Are The Steps Of The Blood Circulation In Heart Flowchart?

Blood circulation in the heart flowchart is divided into the left and right sides. The right side is the flow of deoxygenated blood. The left side represents the flow of oxygenated blood.

There are 14 steps in a circle of blood for easy illustration:

  1. Deoxygenated blood starts to run from the body
  2. It flows into Superior/ Inferior Vena Cava
  3. The flow of deoxygenated blood  reaches the right atrium
  4. The atrium will push the flow through the Tricuspid valve
  5. The gore stays in the right ventricle
  6. The line will continue to pass the systemic veins and flow into pulmonary valve
  7. The oxygenated blood is pumped into the lungs through the systemic arteries. The marginal arteries will provide the heart muscle with blood.
  8. The hemoglobin comes into the pulmonary veins
  9. It reaches the left atrium
  10. The flow of blood goes through the bicuspid valve
  11. The valve pull it into the left ventricle
  12. The bloodline moves to the aortic valve
  13. After that, it flows through the aorta and coronary arteries
  14. Finally, the oxygen-rich blood moves back to papillary muscle and the body.

Blood Circulation In Heart FLowchart Explanation

Right Side Of The Heart

Superior Vena Cava & Inferior Vena Cava: Vena Cava are the sole vessels that transport deoxygenated blood to the atrium on the right upper side of the heart.

Superior and inferior are on the opposite side of the heart. The superior takes the hemoglobin from the higher parts of the body: the posterior surface of the arms and the brain, and the inferior takes blood from the lower section.

Right Atrium: The atrium is the upper chamber that receives the upcoming blood from the Cava. The right atrium will take the deoxygenated blood from the upper Cava and pump it through the systemic veins - the tricuspid valve.

Tricuspid Valve: The small hole in the valve will help slow down the blood flow.

Right Ventricle: The ventricles are on the heart chambers; it takes up half of the heart space. Once the ventricle contracts, the right atrium will pump the oxygen-poor blood to the ventricle through the tricuspid valve. This will carry blood to the lungs for gas exchange.

Pulmonic Valve: Once the blood gushes, the line will leave the right heart through the pulmonic valve. The pulmonary valve will then deliver enriched blood to the body.

Main Pulmonary Artery: The oxygenated blood will go out of the heart in 2 directions of the systemic arteries - the larger veins of the heart.This blood then enters the capillary vessels and flows into umbilical arteries.

Left Side Of The Heart

Pulmonary Veins: The semilunar valve on the left side will convey the blood directly to the left atrium. In the fetal heart, there will be a small hole between the arteries and aorta called the arteriosus; this hole will deliver the blood from the respiratory system.

Left Atrium: The circumflex artery will push blood into the left atrium, the systemic veins will let the stream come in.

Mitral Valve: This thin barrier helps the blood flow gradually into the ventricle. Without the mitral valve, the heart cannot have enough force to pump the blood.

Left Ventricle: In the diastole, the ventricle contracts will push the oxygenated blood through the valve to reach the left ventricle on the bottom of the heart.will push the oxygenated blood through the valve to reach the left ventricle on the bottom of the heart.

Aortic Valve: After the diastole, the heart will begin the systole. The heart muscle will pump the oxygenated blood up to the aorta through the aortic valve, which is situated between the ventricle and aorta.

Aorta: This is the final step that forces the oxygen-rich blood out of the aorta - the largest artery and coronary arteries. The coronary artery branches, which arise from the aortic sinus, are linked with the circumflex artery. After that the blood is spreaded to the umbilical vein and then to the right organs of the body in the major branch.

Systemic circulation is an important part of our body which will help us keep the healthy weight. If we keep eating fast food or do not drink enough water, we may get coronary artery disease or heart attack. We should exercise regularly to keep the system working well.
