    Hello,
    I hope all is well! I am a little confused here. Arteries = Carries blood away from an organ. Veins = Carries blood toward an organ.
    Renal artery is carrying blood to the kidneys? Renal veins drains/carries blood away from the kidneys?
    Thank you!

    • @professoryu5571

      Hi! Busy but otherwise doing well. I hope you are well too. Good question. If you change just one thing in your note, everything would be correct :) It should be "the heart" and not any organ. Arteries=blood vessels that carry blood away from the heart. Veins = blood vessels that carry blood toward the heart. If you keep "an organ", it would be the opposite. Arteries typically bring oxygenated blood toward an organ whereas veins typically drain the deoxygenated blood from an organ. But notice I use "typically" because there are exceptions. For example, the hepatic portal vein brings blood from other digestive organs to the liver. So in this case, a vein carries blood toward an organ. Hope this helps and let me know if you have further questions. 😊

    HII I love your videos! It really helps to watch your videos as a refresher before I dive into the systems :). I have a question: Do we need to know all the blood vessels within the kidneys or just the renal artery & vein?

    • @professoryu5571
      @professoryu5571  2 роки тому +1

      Great! I'm glad ot hear that 🙂 That's a good question! I'd suggest that you know the renal artery&vein, as well as the arterioles that go in and out of a glomerulus. I think there's a low chance that you will see questions on other blood vessels in the kidney so I would focus on the four that I mentioned. Hope this helps 🙂

    i don’t know why i get confused but is a nephron WITHIN a kidney?

    • @professoryu5571
      @professoryu5571  Рік тому +1

      Absolutely. A nephron is the structure and functional unit of kidney. Each kidney may have about 1 million nephrons and these little "workers" work hard to filter blood and produce urine to get rid of the metabolic wastes in our body. Hope this helps :-)

    • @amayabolanos9250
      @amayabolanos9250 Рік тому +1

      So basically it has to go through the nephron first then the kidney?

    • @professoryu5571
      @professoryu5571  Рік тому +1

      @@amayabolanos9250 No, nephrons are little structures within the kidney (like little rooms in a big factory). If you look at the diagram in the video or any kidney cross section, the nephrons are mostly situated in the outer layer of the kideny (cortex). Some are on the border of the cortex and medulla. They are part of the kidney and not outside of the kidney. You may want to go through some diagrams and get familiar with the different sections of the kidney and know where nephrons are located. It's an important topic and you may see 1 or 2 questions on TEAS. :-)

    • @amayabolanos9250

      Maybe I wrote that wrong, but the nephrons are the little triangles within the kidney is what I was trying to say! Is that correct? When I look at pictures online it shows the nephrons within the kidney in the triangle. Like the little yellow lines. Sorry I just want to make sure because I take the test tomorrow! Thank you!

    • @professoryu5571
      @professoryu5571  Рік тому +1

      @@amayabolanos9250 Okay, that makes more sense, LOL. Since I don't know which online picture you were looking at, I will use the image in my video. If you look at that image (9'20''), the nephrons are mostly in the outermost layer, not in the triangles. The triangles on my picture are empty spaces where final urine (after filtration, reabsorption, and concentration) comes out. So those triangles are like little collecting funnels. Hope that helps a little. Good luck tomorrow!!

    I remember there is a Teas question about the glomerular capsule and blood. Something like the blood efferent/afferent from which part. Some thing like this I don't remember the exactly question

    • @professoryu5571
      @professoryu5571  2 роки тому +7

      Thanks for sharing! I wonder if the question was about afferent and efferent arterioles. Blood enters the glomerulus via the afferent arteriole and exits the glomerulus via the efferent arteriole (think of the "e" in efferent as "exit"). So this is basically what happens in glumerulus: (1) blood in in afferent arteriole; (2) filtration of blood in glumerulus (the filtrate containing water, metabolic wastes, electrolytes, glucose, etc. then enters the Bowman's space and flows to the proximal tubule); (3) blood out via efferent arteriole.
