The microcirculation: get to know it

What does microcirculation entail? And what is happening there? The answers to these questions, as well as more information related to this topic, can be found in the following article.

The microcirculation: get to know it

Pulmonary circulation is generally defined as the passage of blood from the right side of the heart through the arteries towards the lungs , in order to pick up oxygen and return again to the left side of the heart through the veins. In this article, we'll go into greater detail on this subject:

How is the small circulation?

A network of blood vessels called the pulmonary circulation creates a closed circuit between the heart and the lungs. Here are the specifics:

  1. This cycle begins with the transmission of deoxygenated blood from the right ventricle in the heart through the pulmonary vein, which in turn is divided into two branches above the heart, each of which connects to the right and left lung.
  2. The two arteries are then divided into smaller and smaller branches until they reach the vessels or capillaries located in the alveoli (Alveoli), after which the blood absorbs oxygen from the air that is absorbed in the alveoli, and subtracts carbon dioxide.
  3. After that, the oxygen-laden blood flows through the largest and largest blood vessels, reaching the 4 pulmonary veins, which then drain into the left atrium, where the minor blood circulation ends and the systemic circulation begins. 

What is the difference between the minor circulation and the major circulation?

The following are the differences between the minor and major blood circulation:

  1. The minor circulation circulates between the heart and the lungs only, while the major circulation exceeds that to circulate between the heart and all other parts of the body, in order to provide the body parts with the oxygen that was loaded in the blood during the minor circulation.
  2. The minor circulation takes place according to the aforementioned points. As for the major circulation, it occurs as follows: 
  • After returning from the small circulation, blood enters the left atrium and is pumped to the left ventricle by the mitral valve.
  • The largest artery in the body, the aorta, is pumped by the left ventricle into it via the aortic valve.
  • Before passing through the diaphragm, where it divides to supply the lower part of the body, the aorta splits into major arteries that supply the upper body.
  • To get to the capillaries that travel through the tissues, the arteries then divide into progressively smaller arterioles.
  • Exchanges of nutrients and gases take place there, with oxygen playing a key role. Cells release carbon dioxide and metabolic wastes into the blood. The body thus maintains the metabolism of all organs of the body through the great circulation except for the visceral tissue of the lungs.
  • After that, the non-oxygenated blood combines with the smaller and larger veins to reach the vena cava (Venae cavae), which empties into the right atrium of the heart before moving on to the right ventricle, where the small blood circulation resumes, and so on.

Ways to improve blood circulation of both types

When the blood circulation of both types is weak, this means that the cells of the body cannot obtain sufficient oxygen and appropriate food, which affects the health and activity of the body. Here, we'll go over the key factors that improve blood circulation, such as:

  • Stop smoking of all kinds.
  • decreasing the consumption of saturated fats.
  • Don't sit still for too long.
  • 8 glasses of water should be consumed each day, possibly more if you exercise.
  • Doing yoga and jogging exercises.
  • preserving a suitable and healthy weight.
  • Consume foods high in omega-3 fish oil in particular.
  • Drink tea—green or black—both varieties contain antioxidants that are good for your heart.
  • maintaining blood iron levels.
