FUNCTION OF THE SKELETON

 FUNCTION OF THE SKELETON



The skeleton has seven major functions in the human body. This functions are: 

- PROTECTION 

- SUPPORT

- BODY MOVEMENT

- MANUFACTURING OF BLOOD CELLS. 

- STORAGE OF MINERALS AND FATS

- TRANSMITION OF SOUND WAVES

- BREATHING PROCESS

See the explanation below.


PROTECTION 

The skeleton protects the vital internal organs and other solf and delicate tissues from mechanical injury. eg. 

- The cranium of the skull which protects the brain.

- The ribcage protects the lungs and the heart.

- The vertebral column protects the spinal cord.


SUPPORT

The skeleton provide a rigid framework that supports and shapes the body giving it a definite shape and an erect posture.eg. the bones of the legs (tibia and Fibula) supports the entire body when standing, giving it stability.


BODY MOVEMENT

The skeletal muscles attached to bones permits flexibility in the movement of body parts.


MANUFACTURE OF BLOOD CELLS

The red bone marrow of long bones and the rips produce red blood cells, white blood cells and cell fragments call Platelets.


STORAGE OF MINERALS AND FATS 

The matrix of the bones of the skeleton stores minerals such as Calcium and phosphorus needed in body metabolism. Calcium is needed for muscle contraction and blood clot formation. The calcium and phosphorus makes the bone strong and very hard. 

The yellow bone marrow stores fats which acts as an energy reserve. 


TRANSMITION OF SOUND WAVES 

The ossicles (bones of the middle ear which are: malleus, incus and stapes) transmit sound vibration to the cochlea of the inner ear.


BREATHING PROCESS

The ribcage assist the breathing process by continuesly increasing and decreasing the volume of the thoracic cavity (chest). This allows oxygen to enter the lungs where it is transported by red blood cells to the body tissues.

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...
