highly regret not knowing how amazing osmosis was at the start of medical school....Watching these videos right before step 1 is making me realize how much basic knowledge I don't know because it's simply not taught in this way. Osmosis literally describes WHY everything is happening in 10 minutes

I learned about the Lymphatic System back in Nursing School in A&P which was fascinating but over the years forgot some of it's functions. This a great recap and review of this often ignored or forgotten system. I did go to Arkansas many years ago to be seen by a Holistic Doctor who specializes in the Blood System and the Lymph System with a focus on "It's in the Blood" and the components of the blood to diagnosis health problems by observing a drop of blood under a microscope. Then he went into explaining the Lymphatic System in detail as an importance to the Immune System. Since it does not have a pump the video states how lymph is circulated, but he did point out it can be more effective by using gravity to help along with using a small trampoline to bounce on at least once a day for a few minutes to flex muscles with the use of gravity also pulling down to help circulate the lymph even better making it more effective in its job. Our bodies are just an amazing creation that even the most minute parts even into internal cellular function was divinely designed. So, we need to do our part and treat it correctly to better serve us.

Very good diagrams and animations and clear narrative. However I had to pause at 6:50 as the explanation around here becomes incorrect. Dendritic cells sample antigen in the peripheral tissues, at the site of infection e.g. skin, gut, lung. Then are activated, migrate to the lymph node (you say that they pick up antigen in the lymph node which is incorrect). Also they present antigen to T cells, not B cells. T cells become activated and are important for the activation of B cells. You may read in the literature or text books about 'follicular dendritic cells' which present antigen to B cells as part of the activation process and I think that is what you are referring to here, but these are completely different cells to 'dendritic cells' and the similar name is just because they look similar (both have spindley protrusions aka dendrites).

Great video, but there is an error in the immune response section. The dendritic cell induces T cell activation, not B cell activation. B cells can be stimulated by free antigen brought in by the draining lymph. T cells require the presentation of the antigen by MHC molecules on the dendritic cell for activation.

good video but i'm curious about what you mean when you say proteins escape the capillaries...this certainly happens during inflammation, but during normal circumstances there is not much in the way of protein loss through the capillaries to my understanding. also, fenestrated capillaries do occur in the GI tract and some other places, but not in all vascular beds. it might be worth noting this

Albumin leaks through the pores of the capillaries? I thought albumin stayed IN the capillaries (because it was too large) and pulled fluids back in through osmotic pressure. Please correct me if I am wrong.

@coltononline 6 жыл бұрын

albumin is actually small enough to pass through many capillary fenestrations (~50-90nm diameter). It's a 'smaller' plasma protein molecule, only ~4x15nm. So, it does readily diffuse from capillaries in certain tissues. It's the negative charge of the basement membrane which prevents alb from diffusing across into the extra-vascular interstitial space. In the glomerulus, in between the podocyte foot processes (the slit diaphragm), there's the nephrin molecules, whose negative charge prevents albumin from diffusing out into the filtrate (which eventually becomes urine). Alb is normally found in lymph, at ~2 : 2.5 ratio to plasma. This ratio is sufficient to maintain oncotic pressure in plasma's favor in normal patients. I like to remember alb is THE transport protein for many lipophilic molecules (fatty acids, steroids, T4 etc). I don't know if it actually delivers its cargo directly to each cell but that's how I like to remember it can actually leave the vasculature. hope that wasn't too confusing...

@kirondatta6061 5 жыл бұрын

Albumin is actually small. It can even pass the the glomerular capillaries fenestrations. Since plasma proteins are negatively charged, it cannot pass the filter (under normal body pH)

Yikes! Albumin absolutely cannot normally drain from the capillaries into the interstitial fluid as was stated around one minute into the video! Huge error right off the bat. If that were to happen, which does happen in burn victims, the tissue would swell like crazy because there would be no Oncotic forces to return the interstitial fluid into the distal capillary. Just finished the video, other than that mistake about albumin, the rest of the video was very well done! Thumbs up!
