what is unique about blood in pulmonary arteries compared with blood in other arteries? This is a topic that many people are looking for. star-trek-voyager.net is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, star-trek-voyager.net would like to introduce to you Circulatory System | Pulmonary Circulation. Following along are instructions in the video below:
Right ninja arrogance video. Were going to talk about the pulmonary circulation. The pulmonary pulmonary circulation is extremely important within the body because function is to be able to blood from the right side of the heart to the lungs for the lungs to get oxygenated blood.
So we need to take the oxygen from the lungs and put it into the blood that the next thing. Thats also really important for the pulmonary circulation is to take the co2 out of the blood and put it into the lungs. So the lungs can actually exhale.
It and then take that new oxygenated blood and deliver it to the left side of the heart. So recap that purpose of the pulmonary circulation is to pump blood from the right side of the heart to the lungs where in the lungs. The blood is going to pick up the oxygen drop off the co2 and be taken to the left side of the heart.
Lets go ahead and discuss this in detail. So what were going to do is were going to actually follow each one of these vessels and chambers and valves that were going to move through. But were just going to number it for right now and then were going to write down what each number represents so starting.
The circuit off here at the first position here is going to be within. Whats called the right ventricle okay. So we always want to start a circuit at the pump.
Because hes the one whos actually driving the circuit. So the right ventricle is going to be the actual starting point for the pulmonary circulation. So this next thing is from one we got to pump it from the right ventricle up into the pulmonary trunk.
But in order to do that i got to pump it through these valves these pulmonary semilunar valves. So the second thing is im going to have to move into pulmonary semilunar valves. Okay so first is right ventricle second at the pulmonary semilunar valve.
Then when i pump it up through the pulmonary semilunar valves. I pumped through this big old trunk. So they call this the pulmonary trunk.
So this third position right. There is the pulmonary trunk.

Then the pulmonary trunk gets this bifurcation point. Where it can split going to the actual vessel on this side since you guys are looking at the camera and were looking at like in this orientation. Were going to say this is this is the right side and this over here is the left side so when it splits it goes into a right pulmonary artery and a left pulmonary artery.
Okay so for these guys were just going to number it only on this side because were focusing more on this side. But understand that it would be the same thing over here so again right ventricle through the pulmonary semilunar valve into the pulmonary trunk and from that it splits into right and left pulmonary arteries. Now you guys might be looking at this and saying whoa.
Why arent arteries supposed to be red. No im in this situation. Because the pulmonary arteries are actually carrying deoxygenated blood so because theyre carrying deoxygenated blood.
Thats why were representing it here in blue another example of this is actually going to be the fetal circulation. Where the umbilical veins were actually oxygenated and the umbilical artery was deoxygenated just remember that arteries are taking blood away from the heart and veins are bringing blood back to the heart okay. So thats really crucial to understand so now we have two pulmonary arteries right and left the pulmonary arteries will come into the lungs right like in a route kind of structure thrill.
The hylas of the lung. Which is like a little slit like potential space. When it moves in it gives off another branch.
So it gives off a couple branches here and these are these guys here you can see it one two three these are called your pulmonary arterioles. These are just small arteries. Very very high resistance vessels any time you hear the word arterial think about a resistance vessel.
So it controls the actual constriction and dilation responses. Then from here the arterial branches into these nice little capillary exchange vessels. These are going to be very very important why because at the capillary exchange site.
That is where we said were picking up oxygen. And then what are we dropping off. Were dropping off co2.
Okay. Thats crucial there so just remember that that in these capillary vessels here as we go from the pulmonary arterial to the pulmonary capillaries.

Whats happening in the pulmonary capillaries. Were picking up lungs. Im sorry were picking up oxygen and dropping off the co2 okay.
This is the oxygenation process or the gas exchange process. And its a gas exchange is actually occurring between a small little structural unit. Within the lungs.
Called the alveoli okay sweet deal then what happens is from these pulmonary capillaries. They drain into these individual little things that you see here see this red. One there red.
One there red one there these guys number seven is going to be your pulmonary venules. Okay so these are called your pulmonary venules. Theyre small veins.
So we have pulmonary arterioles. Which are small arteries then we go into these guys here. Which are called your capillaries where the exchange vessels and then we go into the small veins.
Which are called pulmonary venules. Then the pulmonary vein ewells one two three come together and make up a nice big old vein. This is called the pulmonary veins and when you take the pulmonary vein.
The pulmonary vein. Youre going to notice all its red. I mean.
Its oxygenated thats because we picked up oxygen and dropped off co2 the pulmonary veins are going to do what then theyre going to bring the blood out of the lungs. Theyre going to take the actual blood out of the lungs and drop it off back to the heart. But now on what side of the heart now were on the left side of the heart.
The left side of the heart is the oxygenating side the right side of the heart is the deoxygenated side. So now.

The ninth point. Here is were going to be in the right atrium. Okay.
Im sorry left atrium. Okay. So thats point.
Were going to be at is the left atrium then from the left atrium. We got to push the blood down through these valves you see these little valves right. There these are important little guys especially on the left side.
It has two names you can either call it the actual bicuspid valve or you can call it the mitral valve okay so from now were going to go from to the left atrium. The left atrium is going to pump it down through the mitral valve and into this nice little chamber here. Which is called the left ventricle.
I still like always repetition is the key to being able to remember these things is unfortunate. Just its just a lot of role memorization. So lets go ahead and get started here so to kind of recap.
It all were going to start off with number one. What is number one here. Its going to be the right ventricle so the right ventricle was the pump.
It was starting the circuit. The second point was going to be going through the pulmonary semilunar valve that was the next structure that we had to go through then after that we had to pump it into the pulmonary trunk. So that was the next one so from the from that into the pulmonary trunk.
Then what then from the pulmonary trunk. We distributed into the right and left pulmonary arteries. So im going to put here pulmonary arteries.
Then from that we had to go to the next point the pulmonary arteries broke down into different types of smaller arteries called pulmonary arterioles. So then we went to pulmonary arterial x.

then from the pulmonary arterial. We go infinitely sort of capillary exchange vessels. But be able to pick up the oxygen and drop off the co2.
So the six point here is going to be the pulmonary capillaries. Then after that after the exchange has occurred. Were going to take it out of these pulmonary capillaries and into these small little veins.
What are those called post capillary venules. Theyre actually going to be called in this case. Its their post capillaries venules.
We call them pull men airy venules. So were going to call this pulmonary vein euls then from the pulmonary vein ewells these venules are going to come all together and form one big old fat vein. Thats called the pulmonary vein.
So theyre going to go into whats called the pulmonary vein then from the pulmonary vein and the pulmonary vein is going to bring the blood back to the left atrium. So its going to bring it to the left side of the heart. And this is going to be the left atrium from the left atrium.
Were going to pump the blood down look through what valve. Its called the mitral valve or the bicuspid valve. So were going to call this one the mitral or bicuspid valve.
Then from that were going to go into the last structure. Here and the last structure that were going to enter into is going to be the left ventricle. So the last one that well go into is whats called the left ventricle left ventricle is going to end the pulmonary circuit.
But begin another circuit it can actually begin the systemic or even the coronary circuit. Because hes a responsible for the systemic circulation. The right ventricle is primarily important for the pulmonary circulation iron engineers.
I hope all of this made sense i really do hope that you guys enjoyed it if it did make sense please hit the like button comment down. The comments that can please subscribe as always engineers until next time. .
