Pulmonary circulation facilitates the process of external respiration: Deoxygenated blood flows into the lungs. It absorbs oxygen from tiny air sacs (the alveoli) and releases carbon dioxide to be exhaled. Systemic circulation facilitates internal respiration: Oxygenated blood flows into capillaries through the rest of the body. The blood ...

Oct 30, 2023 · Synonyms: pulmonary arteries, Arteriae pulmonales. The pulmonary arteries and the pulmonary veins are the vessels of the pulmonary circulation; which means they are responsible for carrying the oxygenated blood to the heart from the lungs and carrying the deoxygenated blood from the heart to the lungs. The pulmonary circulation is different ...

Pulmonary Circulation. Recall that blood returning from the systemic circuit enters the right atrium (Figure 20.5.2) via the superior and inferior venae cavae and the coronary sinus, which drains the blood supply of the heart muscle. These vessels will be described more fully later in this section.

Your pulmonary veins are located between your lungs and your heart. Many smaller blood vessels converge in each of your lungs (right and left) to form a pair of pulmonary veins. Each pair leaves its respective lung through a spot known as the hilum, or root. From there, your pulmonary veins travel to your heart and connect with your left atrium. Th...
Most people have four pulmonary veins, with two connected to each lung (right and left): 1. Right superior pulmonary vein: Drains your right lung’s upper lobe and middle lobe. 2. Right inferior pulmonary vein: Drains your right lung’s lower lobe. 3. Left superior pulmonary vein: Drains your left lung’s upper lobe and your lingula (often called the ...
There are several possible variations of the normal pulmonary vein structure. Some variations affect the number of pulmonary veins you have and how they enter your left atrium. These are healthy and harmless variations. Other variations prevent your pulmonary veins from draining properly into your left atrium. These variations interfere with your h...
The diameter of a healthy pulmonary vein ranges from 9 to 13 millimeters. Your pulmonary veins vary in diameter as they travel from your lungs to your heart. In general, veins gets wider as it approaches your heart. Your left inferior pulmonary vein is the exception to this rule. It starts out wider as it leaves your left lung and gets narrower as ...
Three layers of tissues and fibers make up all your veins, including your pulmonary veins. These layers include: 1. The tunica adventitia (outer layer), which gives structure and shape to your vein. 2. The tunica media (middle layer), which contains smooth muscle cells that allow your vein to widen or narrow as blood comes through. 3. The tunica in...
Pulmonary Blood Flow. Pulmonary circulation is defined as the blood flow that is directed towards and through the lungs. It is not the flow to several other tissues and organs around the body known as systemic circulation. The blood flow through the pulmonary circulation is as follows; the right ventricle, pulmonary artery, alveoli, pulmonary ...
Sep 19, 2022 · Pulmonary circulation is the system of transportation that shunts de-oxygenated blood from the heart to the lungs to be re-saturated with oxygen before being dispersed into the systemic circulation. Deoxygenated blood from the lower half of the body enters the heart from the inferior vena cava. In contrast, deoxygenated blood from the upper ...
