Go to / medicosis The lymph node is a bean-shaped body (not a gland) that interrupts the flow of lymph through the lymphatic vessels.
Afferent lymphatics go towards the lymph node, while efferent exits the node. The lymph node has cortex (which contains the follicle, germinal center, mantle, and margin).
Lymphocyte activation and differentiation occur in the lymph node.
Lymph is a colorless fluid that floats in the lymphatic vessels (lymphatics) of your lymphatic systems.
Formed from the interstitial fluid (extracellular fluid) and returns back to the big veins (Superior vena cava) through the thoracic duct and Right lymphatic duct.
Lymph slows down when it passes in lymph nodes.
Lacteals are a special type of lymph, they are milky because they contain chylomicrons.
Lymph node enlargement can happen in cases of lymphoma (painless lymphadenopathy) or infection (painful).

When i saw 'best explanation ever' in the title i was doubtful. I am so grateful for your video, turns out - it literally is the best ever revision video on lymph systems - i've been revising for days. Bless you!
Thanks, dear.
I am honored!
Can you please help me by sharing?
@@MedicosisPerfectionalis i will x
@ila ila I 100 percent agree!!!!!
Thank you so much 😊
These videos are great, they explain things in a way that are understandable to people without formal medical training! Thank you so much!
You’re very welcome 😊
I've recently found your series & it is amazing ...... really!
thank you for the illustrations.You really helped me a lot.
The explanation was crisp and emphasis on exam and clinical points were great. Subscribed instantly. Great work.
Thank you thank you thank you for creating this content, Breakdown is genius to put it lightly
My pleasure 😇
Can you please help me by sharing my videos with your friends?
this video lived up to the title. you did a phenomenal job simplifying this subject. new sub
Thanks 🙏
Welcome to the community!
Can you please help me by sharing?
I’m a microbiologist and it’s the best for reference for notes to my juniors. 😊
Thank you 🙏
Mam can you suggest me a course after my bsc microbiology??
You are an exceptionally good teacher and an educator ! Keep up the good work!
Thank you 🙏
Your videos help me understand the subjects a lot more! Thank you so much!
My pleasure 😇
You really are amazing in your explanations and diagrams. Thank you! My wife has had 23 lymph nodes removed and neither the surgeon or on oncologist have been able to answer some of my questions on exactly HOW things work. Seems like all they know is how to 'cut & remove' and prescribe drugs.
I am so sorry to hear that! How can I help?
Would you be able to show what the body does, to lymph fluid AFTER nodes are removed (i.e. the armpit)? I know the affected arm develops lymphedema, but does that 'stagnant' lymph fluid eventually moves to other areas of the body & develop another cancer ? Thanks for your concern.
I don’t think so...Have you heard of any cases where the lymph moves to cause lymphangiosarcoma elsewhere?
your videos are life saving, thank you so much, they are perfect
The best on youtube. It helped me clarify this topic
wow 💖 thanks,,,,I was studying non Hodgkins lymphoma so ur video helped me to quite understand its origin types.

What is the name of the sterilization process that occurs in the nodes in effect turning the lymph viable and ph friendly to enter the venous cardiovascular system into the atrium of the heart? Tremendous question 👏.
Waoo ..what a great teacher you are ...mind blowing .. thankyou so much sir..

Thanks its very good explanation 👌🌸
You’re very welcome!
How is it possible to reach a deep lymph node without an fna? For lymph nodes draining from breast it it used?
Very informative maybe you can help me understand The process that takes place that causes a lymph node to calcify. Also, once calcified how is the lymph system influenced by that calcification? does the lymph cease to flow past that node?
Do we know the name of the sterilization process that occurs in the nodes?
very informative video
Amazing job👍🏽👍🏽👍🏽
Love the explanation, thank you
My pleasure 😇
Great video sir, thanks for your efforts
Absolutely!
Ur an angel in disguise. Thank u so much.
Thank you 😊
That was Great!
Thanks a bunch!
Well explained
Definitely the best!
Thank you 🙏
I’m glad you have a good explanation of this - I’m wondering why my lymph nodes swell almost 2-3 times a year after I’ve gotten my tonsils removed. Antibiotics have NOT been my cure. I don’t want to feel hopeless but it’s very alarming at this point & frustrating to not a a real cure.
I am so sorry to hear that!
What does your doctor think?
Medicosis Perfectionalis The previous doctor said sinus infections. Im in a new state currently - my goal to choose a new primary doctor after this pandemic.
I agree
You are a genius
BC B cells contained in C for Cortex. I think first contact is B cells which remove while T cells kill own cells, is it so??
You mentioned that FNA should jot be use in Lymphoma many times here and in other video but never mentioned the reason, is it because of the low sensitivity and that they can be easily missed in FNA?? Or is there any other reason?
nice demonstration
thank you
You’re very welcome 😊
it is just so great sirr!
Thanks:)
great explanation. i love it
Thank you so much 😊
Fine needle aspiration is not done for lymph nodes? Why? Could you please explain

Shukran akhi welcome to my UA-cam channel.
excellent.
Thanks:)
Little bit fast but nice explain with covered all points 👍
Great video.🔥
But why we can't do FNAC in lymph nodes? Isn't it the first choice of investigation to exclude malignancy?
You biopsy it using core needle biopsy (or excisional biopsy), but not fine needle aspiration.
Thanks!
Nice one ❤️
Thank you 🙏
This is really appreciable 👏👏👌👌 loves from pakistan
Thank you 🙏
Science is my thing so I love science
thank you. ...
My pleasure!
5:30 isn’t it the other way around? Flowing in is Afferent, flowing out is Efferent?
That’s exactly what I said.
Afferent is in, efferent is out!
