Blood 1, Plasma, constituents and functions
HTML-код
- Опубликовано: 14 май 2015
- A lesson on the components of the plasma. Plasma is a yellowish fluid which is about 91% water. This keeps the blood fluid,
allowing it to circulate around the body. The rest of the plasma is made up of various substances in solution and suspension; these include plasma proteins, nutrients, dissolved gases and waste products.
Plasma proteins
Proteins are organic molecules made up of precise sequences of amino acids
which are chemically bound together. There are three main plasma proteins;
albumin, globulin and fibrinogen. Proteins are very large molecules and their
presence is vital to generate plasma osmotic potential. Without this osmotic
property the blood would be unable to reabsorb tissue fluid into the venous
ends of the capillaries. Albumin is the most common plasma protein and also
generates most of the osmotic potential of plasma. The globulin proteins include
the immunoglobulins, also called antibodies, which allow the body to fight off
infections. Without these immune proteins we would probably die from the
next viral or bacterial infection we pick up. Other globulin proteins act as carrier
molecules which transport some hormones and minerals around the body.
Fibrinogen is a plasma protein which is essential for the process of normal
blood clotting.
As fats are not soluble in water they are transported around the body bound
to plasma proteins. These combinations of fat and protein are termed
lipoproteins and are soluble in water.
Nutrients and waste products
Plasma carries absorbed nutrients from the gut to all of the tissues of the body
which need them. These include glucose, amino acids and vitamins. It also
transports waste substances such as ammonia from the tissues to the liver, where
this poisonous waste is converted into urea, which is much less toxic. Once
formed, the urea is transported in solution from the liver to the kidneys for
excretion.
I'm finishing my BSc online and I've been missing lectures more than anything. I'm so happy I've found you for my immunology course!
The words are just being absorbed into my brain like water. Thank you much Dr. Campbell you ROCK.
My Mentor and a role model. Words are not enough to express my sincere gratitude and appreciations to you. You are the reason behind all my success. Wishing you a very long life and prosperity.
Rabiu Hassan Thanks Rabiu, its always good to know the videos are bing useful. I hope the material is helpful in all of your work as you help people, John
I agree with you @rabiu hassan
This is the third time that I'm listening to this lecture and you still make it so interesting. And, to a layman, it's so absorbing. Thank u Dr.Campbell.
Just remembered "Campbell's Physiology notes for Nurses" proud to have you Sir
Rabiu Hassan Thats an old one, check out the new edition. Interesting that you came across that one though.
This is literally so important and has now been understood
Thank you Dr. Campbell
I just love how you teach....I am doing nursing anaesthesia and your just awesome.

Dr John Campbell, I'm very grateful for your generosity . I'm a first year medical student. Honestly, since I started following your lectures they courese I'm doing all become very easy and clear to me through your lectures. The way you explained have helped me to understand it better. May God rewards you and give good health and long life to continue to task of kindness especially for us medical students or anyone who is interested in learning or working in health field.
Beatifull lesson, well done Dr. Campbell
If this technology was available in the 60s, humanity would have NO NEED to pay for education.
I have learned all disciplines of science with certifications, only to relearn everything via teachers like this gentleman.
Your time and effort can only be appreciated with a nod, or thanks, but truth is, you are creating scientists. Uncertified educated scientists, whom, in return will teach and awake the Voodooists.
Thank you for this kind feedback Mswahili, If I can make the smallest contribution to bring science instead of harmful traditional practices I will be delighted. You are also correct about the educational racket that is around the world, we should teach our best people to be great, regardless of ability to pay.
SO GREAT SIR. This convinces me that there is always great person to learn from...
Mr John only God can reward you, thank you
Very clear,informative.Its a great talent to explain such a simple way.May God bless you.
I love the way he looks into the camera. It's as if he's giving you that professorial stare to be alert for high yield information for the next test.
You are very articulate, and your teaching style is exceptional. You are admirable, I gain vast wisdom from your videos. You are awesome. Thank you.
thank you very much Dr John. your videos are excellent and easy to understand. I'm glad I found you on here. thank you

thanks doctor but I may have little confusion related to fibrinogen you know during clotting fibrinogen is consuming so it not found in plasma proteins
thank yous this helped me learn alot for year 7 science thanks i realy apreciate it
Hi Dr. thanks very much. the video was explicit.
Only teacher i will say more than is Dr Najeeb sir respect for u❤️

Your a life savior😘💞
Thanks dear sir for sharing ur knowledge with us and make it easy for undersranding
amazing thnx alot hope u can share more videos about physiology .this semester we are due to finish Gaston and Hall medical physiology textbook it's enormous amount of information for 3months study most of chapters assigned as self study...thnx for everything👍
He’s amazing
Thanks a lot:)
Thank you so much sir 🙏🙏

well said mister =) =D loved the tutorial
So in this lecture you discussed plasma minerals as solvents such as vitamin B and C .
So what of vitamin K is it part water soluble?
Thx for the info playa
New one??? Book title Sir,
I will be great if you will take some classless regarding Nursing theories and their applications.
Once more, thank you Sir
Good teaching
thank you so much Dr, but I have one question please, why we have to give newborn baby's fresh blood and how we decide whether it's fresh or not? thanks
O yes intoxicating lecture
A nice video. Thank you very much.
I am asking if there is any explanation of Wilmut paper in litters to nature "viable offspring derived from fetal and adult mammalian cells"? Thanks in advance.
when my science teacher explained this i did not get it
but with this accent i did
Very interesting proud of you but we need the name of the new edition of nursing books thanks.
Khadija Umar The best way depends on where you live, my website is campbellteaching.co.uk
you can message me through this web site, John
thank you , now I know because I though plasma are treatment for leukemia... again thank you so much",) god bless
😊
i am suffering from chemical septic poison since 9years which test is useful
Im sorry to hear this, although I do not recognise this condition, have you seen a local doctor?
holy shti this video is awesome.
when my professor explains shit, it's very piecemeal and superficial. . .then i get a video like this to help me understand plasma and it ties everything together.
I got some questions to ask you if you can help me please Dr. Campbell. I want to message you privately but can’t so I ask you here my mom recently find out she have too much plasma in her blood my questions is what happen if you have too much plasma? What cause it? Is it there treatment? Can it be curable? Sorry I ask to much questions appreciate it.
Why don't thay call Minerals for what they Actually ARE
Elements ¿¿¿¿
Ok
Who's here after watching Covid19 survival from plasma? Thanks
