BLOOD CLOTTING

 BLOOD CLOTTING 


Platelets are the blood cells responsible for the process of blood clotting in the body.

how do they carry out this function?

when ever we have an injury and blood start oozing out, platelets which are responsible for blood clotting releases and enzyme called Thromboplastin.

this Thromboplastin react with Calcium ions and vitamin k to convert inactive plasma proteins called Prothrombin to an active form called Thrombin.

Thrombin convert soluble plasma proteins called Fibrinogens to and an insoluble form called Fibrin.

Fibrin forms a mesh network of fibres across the wound or injury, trapping blood cells and forming clots hence preventing blood lost.

Phagocytes comes to the area of injury to engulf and destroy any pathogen that want to enter the body through the wound or injury.


If you want to really see how this process take place in the body practically, follow this link  and watch the video.

DIFFERENCES BETWEEN WHITE BLOOD CELLS AND RED BLOOD CELLS

  DIFFERENCES BETWEEN WHITE BLOOD CELLS AND RED BLOOD CELLS RED BLOOD CELLS  WHITE BLOOD CELLS    1.   Biconcave disc shape Irregular in shape   2. Hemoglobin present. Hemoglobin absent   3. No nucleus in matured red blood cells    Nucleus present   4. smaller in size and more numerous larger larger Larger in size and fewer in number   5. Transport oxygen from the lungs to the tissues and carbon dioxide from the tissue to the lungs.   Defends the body against infection and disease    6. Only one type.   Many types

MOLE CONCEPT

  THE MOLE CONCEPT INTRODUCTION   In ordinary life items are counted using a named collection of them or counting units. For example, farmers eggs in dozens (12), shop keepers sell sheets of papers in reams (500 papers), Elementary chemical particles (atoms, ions, molecules, electrons, etc)are very small.  Chemist therefore, for convenient reasons count them by weighing a collection of them. The counting unit in chemistry is called THE MOLE (6.02X1023particles). The number of atoms in exactly 12 grams of carbon-12 isotope is chosen as the standard.  What is a mole? The mole of a substance is the amount of substance that contains the same number of elementary particles which are (atoms, ions, molecules) as there are in exactly 12 grams of carbon-12 isotope.  Mole=mass/molar mass In the definition of mole above,  we see that: 1 mole of hydrogen atoms, H, contains 6.02x1023 hydrogen atoms, H. 1 mole of oxygen molecule, O2 , contains 6.02x1023 oxygen mole...
