Supply of blood in blood vessels located in nose increases when someone catches cold. The only place where blood cannot be found in human body is the cornea (eye) because cornea is capable of directly extracting oxygen from air.ģ3. We find pus kind of disgusting but it is actually nothing but white blood cells that died while defending our body against infections.ģ2. Most of this gold is actually in our blood. There is no such thing called artificial blood.ģ0. Humans can have artificial heart but there is absolutely no substitute for human blood. This type of donation is known as Apheresis.Ģ9.
Platelets, red blood cells and blood plasma can be separately donated instead of donating blood as a whole. Donated blood plasma can be stored for 1 year in frozen condition.Ģ8. Donated platelets cannot be stored for more than 5 days.Ģ7. Donated red blood cells cannot be stored for more than 42 days. Platelets, plasma and red blood cells are constantly produced by bone marrow.Ģ5. Red blood cells survive in circulatory system for no more than 120 days.Ģ4. If they find any harmful bacteria, granulocytes will destroy these bacteria by engulfing them.Ģ3. These cells roll along blood vessel walls and hunt for bacteria. Blood consists of a special type of white blood cell known as granulocyte. Blood plasma we mentioned earlier makes up around 55% of the total volume of blood present in human body.Ģ2. A new born baby will have around 1 cup of blood in its body. The average volume of blood present in an adult male body is 5.6 liters while an adult female body contains 4.5 liters of blood on an average.Ģ0. An adult body has 100,000 kilometers or 60,000 miles of blood vessels running throughout the body.ġ9. Though we are familiar with common blood types A, B, AB and O, which is a part of simplified ABO system, there are actually around 30 different recognized blood groups or blood types.ġ8. Average blood pressure will always vary from one person to another despite the fact that standard considered BP is 112/64 mmHg.ġ7. High BP implies increased risk of stroke and heart attack.ġ6. Blood pressure is actually the pressure exerted by blood on blood vessel walls. At the same time, it also carries away unwanted waste material away from the cells.ġ4. Blood is not just responsible for carrying oxygen to different parts of the body. Similarly, blood clot in brain can lead to stroke.ġ3. If blood clots in blood vessels of heart, one can experience heart attack. While blood clotting is meant for good, it can become dangerous.
Platelets are completely different and are responsible for blood clotting whenever bleeding occurs because of a cut or bruise. They also fight cancer cells and other unwanted material that enter human body. These white blood cells are responsible for fighting viruses, bacteria and other infectious diseases. Unlike red blood cells, the white blood cells in our blood form the defensive system of our body. Oxygen combines with this iron and gives the characteristic red color to our blood as well as hemoglobin.ġ0. Hemoglobin is actually a protein that contains iron. Only the red blood cells in our blood are responsible for carrying oxygen.ĩ. The cells then get collected at the bottom of the tube, separating blood plasma from the cells.Ĩ. Blood plasma can be separated using centrifuge device which spins blood at a very high speed. Platelets, white blood cells and red blood cells are all found floating in blood plasma.ħ. Blood plasma also consists of hormones, glucose, proteins, gases, electrolytes and nutrients. Blood plasma is primarily made up of water.
Blood consists of a yellow liquid which is known as blood plasma.Ĥ. Platelets, white blood cells and red blood cells are present in blood.ģ. Nearly 7% of the body weight of a human is made up of blood.Ģ. We are sure, you will be surprised! Are you ready? Interesting Human Blood Facts 1-5ġ. Let us learn 80 interesting human blood facts in order to find out some really amazing facts about this fascinating body fluid. But is that the only function of blood? Not really! There are other important functions too. In absence of blood, body will fail to receive any oxygen which will result in death. One of the most important functions of blood is to carry oxygen to different parts of the body. Without this fluid, no human can survive. Human blood is an incredibly important fluid.
