Hello Dr.Yu! I’m just stopping by to thank you immensely for all of your hard work bringing these topics together. I took the TEAS today and received a 98% on the Science portion and a 91% overall. I only used your Comprehensive TEAS playlist to study, so I’m extremely appreciative with your guidance. You’re a fantastic professor and I cannot praise you enough!
Wow, that is AWESOMME! I don't know if I could score a 98% on the science, LOL - what an excellent job! Thank you so much for taking the time to share this great news. I'm glad my study materials were helpful, YAY!😄
I want to thank you Prof. Yu for making these science videos :) I have studied almost all your videos for the science section of the TEAS 7. I appreciate your efforts for making these videos. And because of your videos and your clear explanations, I passed my TEAS 7 exam today!
WOOHOO! Congratulations!!!!!!😀 I am so happy for you and proud of your achievement! Thank you so much for your kind words and for taking the time to let me know that you passed TEAS. That meant a lot to me so thank you! Good luck with the nursing school application - that should be less stressful than taking TEAS, lol!
@@cupcakecupcake1998 I mostly studied off at first with Smart Edition and then I came across Professor Yu’s videos for the Science portion and I watched most of her videos as a supplement :) I also did watch other science videos to help me as well, such as Tutor Geek, Organic Chem Tutor, and Tyler DeWitt’s videos. Hopeful this helps! :)
Good question! instead of me just giving you the answer, how about I ask you a question and if you can figure it out, then you will answer your own question LOL. Where in the body are erythrocytes produced?
@@professoryu5571 Erythrocyte production occurs in red bone marrow. RBM is found in the bones. I would say skeletal. The kidneys just have the hormone of the RBC initiation.
@@adat1568 You got it! Skeletal system (specifically red bone marrow) is the correct answer! For the urinary system, I'd say remember erythropoietin and that it promotes RBC production to maintain RBC level homeostasis.
Good question! First of all, the lymphatic system and the immune system overlap. Recall that besides draining and returning excess fluid back to the blood, the lymphatic system also houses immune cells and performs body defense. So I wouldn't separate them and think of them strictly as two different systems. The lymkphatic system is a really odd one - it's part of the circulatory system and part of the immune system. Fascinating, isn't it! Second, as mentioned earlier, the lymphatic system houses immune cells including macrophages and leukocytes (T and B cells). They inspect lymph (the fluid circulating in the lymphatic system) and target foreign invaders. So you can absolutely say that those immune cells are components of the lymphatic system - analogy: think of the lymphatic system providing another battleground for those immune cells to destroy pathogens and protect our body. Hope this helps and feel free to let me know if you have further questions 🙂

Was her science videos the only thing you used to study?

Congrats ! I take mine tomorrow … how was the science section as far as chemistry and biology ? I
@@getfitwithash5151 I thought the science portion was fair for the most part at least for the biology and chemistry.🙂
Which system is responsible for erythrocyte production? Urinary system or skeletal?

Hi Prof Yu! For Q#2, wouldn't Macrophage & Leukocytes technically be part of Immune System not the Lymphatic System? Thank you

@@professoryu5571 this makes sense to me. Thank you so so much!
@@mlee1023 Great! You are very welcome!
👍
Thank you! 😊
