The Immune System: Overview Updated for 2024

1. The thyroid gland is in the neck. The THYMUS gland is located in the mediastinum and is the destination for T cells. Plasma cells secrete immunoglobulins.

2. How about a Human response to the male sperm cells present after intercourse? If an engineered variant of a naturally occurring mucous membrane product in the vagina would treat the presence of the foreign male sperm as an invasion and attack it, this could be a way to induce birth control. The mechanism would need to be temporary so as to not make the woman permantly react and essentially become unable to concieve.

   Imagine a Mast cell present in the female vaginal mucosa being triggered to produce genetically altered histomine or some similar chemical that would attack male sperm?

3. I attribute my own ability to ward off the common cold more than the average person with my living in a relatively good air quality region of America and living coastally where I will surf in the salt water even in Winter as the water temperature may only reach 69 F.

   Humanity seems to want to congregate in massive cities with very poor air quality and they often live in static air environments that promote shared air spaces amongst dozens if not hundreds of persons. I susxpect that this area around the Treasure Coast of Florida having better air quality, lower popultion density and proximity to a salt water ocean, as having a better respiratory health state overall in the population. So please folks from NYC while I want you to get better, don't all of you move down here and upset the ecological balance with excessive human activity.

   The area is stressed enough. All one has to do is look at the historical archive in local museums with pictures of Stuart and the St. Lucie River circa 1915-1930 to see sky blue clear water with a healthy marine sea grass river bed, biodiversity rivaling the coral reefs and massive and healthy fish stocks Now roughly 100 years later, with a much larger population of humans and automobiles, the water quality has deteriorated to that of the appearance ot Tea! Very sad.

   I am glad to see the immediate response in improved air quality in areas like Industrial China and Northeast America during the Covid-19 epidemic of Winter of 2020. It was dramatic and welcomed. Sad we had to be forced to shut down our population for two months to prove a point. We humans are dirty, too many in number and too distant from any healthy ecological balance with our natural world.

4. Older cultures have traditional therapies to deter infections. I give examples like the Sweat Lodge, the mineral baths, the sauna, the winter cold water plunges or polar-bear club swims, the sea water swims. Seems to be combination of temperature extremes and/or pH and salinity extremes to shock the external bacterial invaders that prefer human temperature and ph and salinity to grow in.

5. Does the Liver produce chemicals that attack generic infecton? Is there any related study of earlier classes of organisms liver function related to cancer therapy? I wonder if the class Chondrichthyes or cartilagenous fishes, a very old group especially sharks that often have very large livers and often do not produce cancer.

6. Is it fair to describe the adaptive immuosystem as a sort of chemical equivalent to "learning"? So then a viral infection that mutates to respond to chemical differences in different host organisms is also some form of elemental chemical learning, typically transcribed in the RNA strand like the reverse single strand SARS Covid-2 virus?

   There must be a fairly simple and quick learning process, where large number of viruses with random point mutations along the RNA cause slight mutant expressions of proteins in the virus structures. So it bombards the host with several virus nuclei that have variation in expression of the protein such as the attachment protein. These variants are either successful or not, and it is simply a numbers game of trial and error over and over again, with the virus able to express mutations faster than the Host organism can respond adaptively.

7. Oi, it's me way of beating the snott our of the little buggers!

8. Can I make a suggestion, when you finish with the presentation can you not cover the whiteboard so I can take a screen shot of the info to review it later, otherwise I have to take two screen shots when you're in different positions. Thank you for a great video.

9. Great video, very well explained. Thank you so much!

10. Thank you! for helping me to understand this.

11. Omg do you have my class schedule? This is perfect timing for me since i didn't understand my lecture earlier hahaha

12. It’s not a short video.. this is a whole lecture. But keep it up.. just don’t say “a short video “😂

13. Thanks

14. 👍👍👍👍👍❤

15. Best one Sir Carry On such video which help students

16. 👍
