Order the following to trace the path of blood flow from the LEFT ATRIUM until it reaches the LUNGS. Note: you need to consider all relevant chambers of the heart, valves, and blood vessels. Left atrium Bicuspid valve Left ventricle Aortic valve Aorta Systemic arteries Systemic arterioles Capillaries in organs and tissues Systemic venules Systemic veins Superior/inferior vena cava Right atrium Tricuspid valve Right ventricle Pulmonary valve Pulmonary trunk Right and Left pulmonary arteries Lungs

Transcript

00:01 In the other questions, let's talk about the heart.

00:03 This is what we have all the options that we have to place in order.

00:08 We're going to start with a left aethion until it reaches the allowance.

00:12 So let's start here.

00:14 We have the heart.

00:15 And the heart has four chambers.

00:19 It has a right atrium, it has a right ventricle, it has a left atrium and the left ventricle.

00:24 So if we start at the left at the left atroon, the blood is going to move to the left ventricle through the atrial ventricular valve here that in the left side of a heart is called the mitral valve.

00:36 Then the blood is going to be injected to the aorta artery, to the aorta artery, and here it is going to reach the systemic arteries.

00:51 It means all the arteries that arise from this aorta artery, okay? after it gets to the systemic arteries, to a systemic arteries, the arteries are going to branch.

01:02 You are going to branch into arteries, arterials, and then these arteries are going to branch into capillaries.

01:18 Again, in capillaries, they are going to be found where the tissues are.

01:23 Here you have the tissues, for example, and here, not only exchange is going to cure, and your blood is going to become the oxygenated.

01:30 So you're going to have here the venous side of your capillaries, and then you're going to have here the venous, and then you're going to have here the veins.

01:41 And these veins are going to return to the heart, specifically to the right atrium of the fat.

01:50 Then this blood is going to move to the white ventricle through this atrial ventricular bulk.

01:54 Here there is that in the white side is called tricuspid valve, and then this white ventricle is going to eject the blood to the pulmonary arteries.

02:02 Okay, the right and the left pulmonary artery.

02:05 And then this blood is going to come, or it is going to get to the lungs.

02:18 In the lungs, gas exchange is going to cure, and your blood is going to become oxygenated again.

02:24 And this oxygenated blood is going to move through the pulmonary veins back to the left atrium of the fat.

02:32 Okay, so this is all that's here.

02:34 Now let's order all of these options here.

02:39 And let's start with the left atrium.

02:41 Left atrium is number one.

02:44 Then you're going to have the mitral valve that is between the left at the left ventricle and the the mitral valve is also called by guspid valve.

02:53 So you have here number two.

02:55 After this, you're going to get to the left ventricle of the heart.

02:58 So it's going to be number three.

03:00 Then you're going to move to the aorta through this valve here that is between the left ventricle and the aortic artery that is called the aortic valve...
