So based on the previous posts, we strongly believe you have a rough idea on generally how blood is important to us. Now, we have spoke about blood and its components, how blood cells are produced, red blood cells, white blood cells and their functions. Therefore, today we are going to post on PLATELETS. PLATE WHAT??? PLATELETS??? WHAT'S THAT??
Based on our previous post, platelets are one of the components of whole blood cells.
hmmm... PLATELETS? does it sound familiar especially if you have experience of diagnosed with Dengue Fever?
Yes? well let us tell you..
Platelets are tiny cell fragments that circulate through our bloodstream. Their role is to help stop bleeding when there is an injury to our body.
How does it work?
We think long blabbers wouldn't help you understand how it works.. So let's watch this video together...
Clotting process
Did the video help?? We certainly hope it did. As we know the function of the platelets aren't you curious what would happen if there is too much of platelets in you body? or what would happen if there is too less platelets??
A normal platelet count ranges from 150,000-450,000 per microliter.
Low count of platelets are known Thrombocytopenia
Thrombocytopenia signs and symptoms may include:
Easy or excessive bruising (purpura)
Superficial bleeding into the skin that appears as a rash of pinpoint-sized reddish-purple spots (petechiae), usually on the lower legs

Guess it has been quite sometime since we have updated right? wondering what is the title about? Well it has been too much of reading isn't it?? So today, we decided to give a break with long facts and images.. Instead... we are going to post videos on few facts we have shared previously. We managed to find a few short videos that helped us to enhance our understanding on Blood cells, Whole Blood, White Blood Cells, and also production of blood cells.. So hereby, let us share it with you... Lets be amazed together knowing how this tiny cells in our body do amazing things.. the first video is about The components of the whole blood...
The Components of Blood !!
Well.. next.. lets see how our internal body soldiers work and how do they look.. what?? soldierss??
Yes it is our White Blood Cells (leukocytes).. remember?? Major function of White Blood Cells are to fight against infections and microbes in our body..
*drum rolls*....
The Leukocyte's structure and their Functions...
Finally, a short video on production of red blood cells! yes the main cells that are responsible for our body's Transportation and Regulation... excited to know how? Lets watch...
Erythropoiesis (Production of Red Blood Cells)
Well.. that's a wrap for now.. please keep updated with a upcoming posts. Don't forget to click the follow button to keep updated with our interesting facts sharing..
Hope this video are interesting and fun at the same time helped you understand better!! comment below.. it will help us improvise..
Hi everyone, welcome back! For today we would like to briefly share our knowledge on.. *drum rolls*
Hemopoesis
Wait, hemo what? What is it? What does it stands for? Clueless? Well, Hematopoiesisalso known as hemopoesis or
hematogenesis is the production of all types of
blood cells including formation, development, and differentiation of blood
cells.
Do you know wherethis process occurs?? No??
Let us tell you..
In fetus (extramedularry hematopoiesis)
·0-2 months in yolk sac (there is blood island where red blood
cells can be seen clearly)
·2-7 months blood cells migrate to liver and spleen (it
continuous until two weeks after birth)
·5-9 months bone marrows of most bones
Infants (medullary hematopoiesis)
·Occurs in red bone marrow
·In child red bone marrow is throughout skeletal system.
In adults
·Hematopoiesis specifically occurs at red bone marrow in
vertebrae, ribs, sternum, skull, pelvis and,proximal end of femur
Are you wondering what medullary and
extramedullary hematopoiesis means? Aahhhahhhh.. let us tell you..
Extramedullary hematopoiesis : production of
blood cells outside red bone marrow. For example, liver and spleen.
Medullary heamtopoiesis : production of blood
cells within the red bone marrow.
Before we move in deeper lets get to know few terms:
a)Eryhropoiesis : Production of Red Blood cells
b)Leukopoiesis :
Production of White Blood Cells
c)Thrombopoiesis : Production of Platelets
Now, lets get deeper..
The process initially begins :
In 2 weeks old embryo, red blood cells precursors can
already be recognized in the blood island which is in yolk sac.
Leucopoiesis and thrombopoiesis begins only after 6th
week old embryo when megakaryocytes and granulocytes can be seen in the yolk
sac.
In contrast to red blood cells, lymphocytes which are a type
of white blood cells are formed in lymph sacs which develops in 7th
week of an embryo.
FETAL HEMOPOIESIS
At 2nd month of gestation, fetal blood cells
development will begin at the liver, hepatic hematopoiesis (where the liver is
the chief source of fetal blood cells until 30th week of pregnancy).
At the 10th week of pregnancy, spleen will begin
production of blood cells until 2nd trimester. Spleen is a secondary
important blood production organ.
About 20th week, bone cavities will start to form
and by 40th week of gestation, the bone marrow will become entirely
source of blood cells production in human.
HEMATOPOIESIS IN
CHILD AND ADULT
·At birth until 3 years old , hematopoiesis
merely fills most of the red bone marrow space in almost every bone. Extramedullary
hematopoiesis will continue after 2 weeks of birth.
·At
4 years old, skeletal growth exceeds the demands of red blood cell production.
Thus hemapoietic activity moves to axial skeletal (vertebrae, ribs,
sternum, skull, pelvis and,proximal end of femur) completes at 18 years old.
·Thus, as the child grows into adults, the
available bone marrow space expands and are eventually filled with inactive yellow
bone marrow.
·Extramedullary hematopoiesis in adult only
occurs if:
I.Bone marrow is not functional
II.Bone marrow cannot keep up with demand for blood
cells.
Blood cells are produced by a stem cells which includes formation, development, and differentiation of blood
cells. Inclusive of red blood cell, white blood cells and platelets.
Image below shows a general description of
how our stem cells differentiate to become blood cells.
Hematopoiesis
process=)
Pheewwwwww! Too much information at once isn’t it??? There
are more but don’t worry.. watch the video below for a brief understanding of
how blood cells are produced.
Hematopoiesis Made easy !!
That’s all for today.. =) Hope our post was informative
enough. Feel free to drop your comments
on query or suggestions. Your feedback is our tool for improvisation.
