Blood Hemostasis ( blood clotting ) by Ikram Hamdi


Auchh!! Eewww! Disgusting or feeling like there are cuts on your hand? We humans in daily live are always get in contact or have the risk to get injured. Most of the injury can lead to bleeding for example like cuts, pierced or bitten. Well, if you always spend time in the kitchen, get a little cut by knife of bones of fish is just a normal routine in your daily life. To think, these injury cause bleeding to us. We often get treatment by applying plasters here and there. Applying plasters and maybe some ointment are our action as human to prevent bleeding, but did you know that the main factor of bleeding to stop is from our blood action itself? Yeah today you will know about it. You will encounter some new words like fibrinogen, prothrombin and some other vitamins that may open your eyes widely and be thankful to our blood action.

A cut at the blood vessel
There are many things caused injury to blood vessel for example cuts and being bitten by animal or anything. When injury cause in blood vessel, bleeding will occur and the person will face blood loss. This is where the action begins. This action called as blood coagulation or blood clotting.


The easiest thing to understand the blood clotting process is like plumbers are fixing the leaking pipes to prevent the water leakage. They need some tools and aids to fix the leaking pipes. It is the same concept as blood clotting.


This showed a damaged blood vessel beung recovered by platelet and other cells. When blood vessel damaged because of cut or wound, the platelet action occur. It will release clotting factor to allow forming of platelet plug. If the damage is small then the blood stop completely and contrarily if the damage is severe, fibrim will strengthened the plug. The clumped platelet will activate some helpers we called them as clotting factor. The clotting factors such as thromboplastin where it convert prothrombin to thrombin. This thrombin will aid other friend which is fibrinogen to become fibrin. This fibrin then will make a net or mesh of fibre covering the damage area & prevent blood loss. Well since it is a chemical reaction in the body, it involve some factors for the cut to be blocked but in short, it has the same concept as the plumbers fixing the leaking pipes from water leakage.

By: Amirul Fikri Hi guys!!! Have you ever wonder why you got sick? Have you ever wonder what is the defensive system in our body? Who are the one that willing to sacrifice for us to live more longer? I have always wonder about it since child especially when I became sick. I wonder how I became healthy again, after got a very painful fever and only thinking about death at that time. Very funny to flashback about it but it is the truth when I cried and ask for forgiveness to my parents when got fever. But when recovered, I felt like I have the same power like wolverine in X-men. But when I pursue my studies in medical subject, I realized that there were some bad thing that always got jealousy to our health and some good thing in our body which fighting back and sacrificed for our health. The bad thing that always got jealous to the body health is called pathogens. This pathogens which including viruses, bacteria, fungi, protozoa and worms attacks or infects the body and t...

HAEMOPOIES by: Nurul Shafiqa Have you guys ever wonder how does our blood being produced?  Do you know where exactly is the blood formation takes place? I know some of you might not interested to know about this scientific processes, but as for me,it is fun to know what our body have gone through everyday. Although I used to be like that too when I was a kid, now i feel grateful that I have to learn this to pass my exams. It sounds like I was being forced, hahahaha somehow it's true.😝Nope, we shouldn't be like that! What we learn today must be very useful for our future. Not only we can get benefit from the knowledge, but we also learn on how to appreciate what does our God gives us and be more grateful of what we have compared to other people out there. I still remember the time I fell from my bicycle. I was 6 that time. That is because I wasn't listening to my mom. I still wanna play with my friends although it was just few minutes after the rain stopped. I rod...

                                             HAEMOGLOBIN CATABOLISM By: Safura Damia Hi guys. Do you know our body have 15 g hemoglobin per litres of blood and it can bind with 200 ml of oxygen per litre? And normal amount of blood for woman is 4.5 litres and 5 litres for man. Can you imagine how small hemoglobin molecule are and how much it consist in our body. It beyond your expectation right. So appreciate your blood as how you appreciate your money. But our red blood cell only last for 120 days. After that, red blood cell destruction occur. The cell are removed extravascularly by macrophages of the reticuloendothelial system specially in the bone marrow and also in the liver and spleen. When it destructed, the new red blood cell will replaced the destroyed red blood cell to maintain our body function. So, have you guys ever wondered how normal red blood cel...
