ABO Blood Grouping

BLOOPERS

EXPECTATION VS REALITY

Let's play gameeee !!

Good day Earthlings!!!!

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:

1. Easy or excessive bruising (purpura)
2. Superficial bleeding into the skin that appears as a rash of pinpoint-sized reddish-purple spots (petechiae), usually on the lower legs
3. Prolonged bleeding from cuts
4. Bleeding from your gums or nose
5. Blood in urine or stools
6. Unusually heavy menstrual flows
7. Fatigue
8. Enlarged spleen
9. Jaundice

What's up everyone !!!!!!

BORINGGGG !!???????

Hey everyone!! how have you been ??????

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..

thank you & stay tuned☺

with much love,

Hemopoesis; Where It All Begins

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,

Hematopoiesis also 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 where this 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 6^th 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 7^th week of an embryo.

FETAL HEMOPOIESIS

At 2^nd 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 30^th week of pregnancy).

At the 10^th week of pregnancy, spleen will begin production of blood cells until 2^nd trimester. Spleen is a secondary important blood production organ.

About 20^th week, bone cavities will start to form and by 40^th 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.

Blood Cells; Going Deeper

Welcome back dearies
How are you?? Hope you had a good day..

Well previously we had posted on the functions and components of the blood.. today we are going to go a bit deeper on structure and functions of the formed elements in our blood cells.

Formed elements of the blood

Lets recall..

Do still remember the components of our blood?? YES! The straw coloured liquid is plasma and it is 55% of our whole blood and Formed elements of blood consists of 45% of the whole blood.

So when you look into,

The formed element of the blood are the following:

1.       Red blood cells (erythrocytes)

2.       White blood cells (leukocytes) which are distinguished into two:

a)       Granular leukocytes (the WBC contain granules which can be seen under microscope after staining)

·       Neutrophils

·       Eosinophils

·       Basophils

b)      Agranular leukocytes ( the WBC with no granules under microscope after staining)

·       Lympocytes (t-cells,b-cells and natural killer)

·       Monocytes

3.       Platelets (thrombocytes)

Did you know??

Basically white blood cells does not contain haemoglobin thus they don’t have contain colour. We can only see them under microscope after staining them.

Besides red blood cells does not have nucleus. So they appear biconcave shape to hold heamoglobin.

Red blood cell with haemoglobin

Aren’t you now curious to know how does our blood cells look? Their structure? Their function??

Structure and function of blood cells

There you go.. the table summarizes on the structure of blood cells and its function! There is a clearer image on the white blood cells attached below.

It’s a wrap for today. Hope our post was informative enough.  Feel free to drop your comments on query or suggestions. Your feedback is very much appreciated.

Introduction of Blood; Important?

Do you know how important is our blood?

Lets begin with what are the functions of our blood..

Lets now dive further in to know what are the components of our blood..
Our whole blood is composed of two portions:

1.       Blood plasma- which is a liquid that contains dissolved material
2.       Formed elements – which are cells that support and maintain our body tissues

Components of Blood

Do you know how this cells helps to regulate our system???

The plasma which is about 55% of our whole blood is a straw coloured liquid which transports substances need by the cells and removes waste product from cells

The formed elements which encompasses 45% of our blood contains

Red blood cells (RBC) - contains haemoglobin which carries oxygen from our lungs to the rest of our body

White Blood Cells (WBC) - defends and protects against infections which is a part of our immune system.

Platelets - which is responsible to help our body to clot blood when there is an injury.

Have you ever imagine or wondered on how blood our real blood looks like under the microscope??

Let us show you.

Red Blood Cells

White Blood Cells

Informative enough?
