lessons in our specialization .... For the public benefit

[أبو سراج]

hi evrybody

To the luck beauty

Then our forum fills with the mentalities of your example

They called me that share you by a subject that I hope that is interesting

My subject by an abridgment pours in the good of all people

everyone have any topics about his or her major study can write it here

i will starting about my major - Biology


The cell


all organisms are composed of cell. Some are composed of a single cell and some , like us , are composed of many cells.

What is a typical cell like?

Its contain of three elements :

1) A membranes surround the cell . Isolating it from the outside world. They provide the only connection between the cell and the outside world.

2) The nuclear region directs the activities of the cell , which include DNA .


3) Cytoplasm , contain chemical wealth of the cell : amino acids , sugars, and proteins.
The cytoplasm contain organized structures, called ( organelles) , such as mitochondria , that provide power for the cell.

i'm soooo glad to see you here abu seraj....

what a nice surprise !!!!:D

Thank you for providing us with those scientific information ...

we're waiting for more benefit topics ...

thanks aloooooooot my sisters walai and noor alamal

Your preferable answer encourages me to another scientific topic writing

I will talk today about the photosynthesis operation subject

Photosynthesis

Sunlight plays a much larger role in our sustenance than we may expect: all the food we eat and all the fossil fuel we use is a product of photosynthesis, which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems. Photosynthesis is carried out by many different organisms, ranging from plants to bacteria . The best known form of photosynthesis is the one carried out by higher plants and algae, as well as by cyanobacteria and their relatives, which are responsible for a major part of photosynthesis in oceans. All these organisms convert CO2 (carbon dioxide) to organic material by reducing this gas to carbohydrates in a rather complex set of reactions. Electrons for this reduction reaction ultimately come from water, which is then converted to oxygen and protons. Energy for this process is provided by light, which is absorbed by pigments (primarily chlorophylls and carotenoids). Chlorophylls absorb blue and red light and carotenoids absorb blue-green light , but green and yellow light are not effectively absorbed by photosynthetic pigments in plants; therefore, light of these colors is either reflected by leaves or passes through the leaves. This is why plants are green

THANKS


I hope from the members participating by subjects that cares about their specializations

ThANK YOU MY BROTHER ABU SERAJ FOR EXPLANING THIS COMPLEX PROCESS ....


THE GREAT POWER OF OUR GOD IS SO OBVIOUS IN THIS PROCESS ..


BY THE WAY ... YOU'VE SAID THAT YOU'RE GOING TO PUT ALL THE SUBJECTS CONCERNING YOUR SPECIALIZATION IN THIS THREAD , SO WHY DID YOU CHANGE YOUR MIND ???? ;)

YOU'VE ESTABLISHED A NEW THRED , BUT I'VE DONE A TRICK ;) :D

KEEP IT UP
GOOD LUCK

PLEASE , KEEP ME IN YOUR PRAYERS

[نور الاْمل]

Thank you my brother for this useful post...

we're waiting for more scientific participations ...



god bless you....:)

[أبو سراج]

Many thanks for you my sisters walai and noor alamal again

Your preferable answer encourages me to writing more

Today I will deal the muscles subject and her kinds


THE MUSCLES

Animals use muscles to convert the chemical energy of ATP into mechanical work. Three different kinds of muscles are found in vertebrate animals

1)Heart muscle - also called cardiac muscle makes up the wall of the heart. Throughout life, it contracts some 70 times per minute pumping about 5 liters of blood each minute.

2)Smooth muscle is found in the walls of all the hollow organs of the body (except the heart). Its contraction reduces the size of these structures. Thus it
*regulates the flow of blood in the arteries
*moves your breakfast along through your gastrointestinal tract
*expels urine from your urinary bladder
*sends babies out into the world from the uterus
*regulates the flow of air through the lungs

The contraction of smooth muscle is generally not under voluntary control.

3)Skeletal muscle, as its name implies, is the muscle attached to the skeleton. It is also called striated muscle. The contraction of skeletal muscle is under voluntary control.

I hope that the subject is pleasing you ,and i am waitting lessones to another subjects.

you alsoooooo
please, keep me in your prayers

[ولائي لبني هاشم]

Thank you very much ..... my dear brother abu seraj ....

your topic was soooooo useful .....

i've known a new thing about the muscles ...

i'm trying to put my own subject , and inshallah you're going to see it as soon as possible .;)


and , don't be worry i'll keep you in my prayers ...

Thank you my dear brother for this new subject ....

in fact, all your subjects are soooo benefit .....


we're waiting for another new post....


good luck:D

[أبو سراج]

hi my brothers and my sisters

thanks again for walai , noor alamal., and alsahwani

I will continue with you our subjects in the biology science


The immune system is a complex of organs--highly specialized cells and even a circulatory system separate from blood vessels--all of which work together to clear infection from the body.
The organs of the immune system, positioned throughout the body, are called lymphoid organs. The word "lymph" in Greek means a pure, clear stream--an appropriate description considering its appearance and purpose.

Lymphatic vessels and lymph nodes are the parts of the special circulatory system that carries lymph, a transparent fluid containing white blood cells, chiefly lymphocytes.

i hope your astonishment and there is more,,,,


keep me in your prayers

He , abu seraje , thanked you a lamp on the longing subject

Pure his that we were lost in your last reply webs on him a scientific and they let I perceive the warrants through that,
for example the white blood counts or the corpuscles red
We are industrial in mechanical :D

didn't make a distinction between them :D

[أبو سراج]

hi every body
sorry about the late
Because I was occupied

I will deal the digestive system subject

digestive system

The digestive system is a group of organs that work like wrecking equipment to break down the chemical components of food, through the use of digestive juices, into tiny nutrients which can be absorbed to generate energy for the body. This system also builds and replaces cells and tissues, which are constantly dying. Digestion begins in the mouth with the teeth, which grind the food into small particles; the tongue, a powerful muscle which detects "good" and "bad" flavors in food and manipulates the food between the teeth for chewing, and saliva, a watery fluid which lubricates chewing and swallowing and begins the process of digestion. The digestive system begins in the mouth, continues in the pharynx (throat) and esophagus and into the "gut" region: the stomach, small and large intestines, the rectum and the anus. Food is chewed, pulped and mixed with saliva to become a soft mass which will easily travel down the esophagus. The tongue traps the food and forces it into the throat, which is a mass of muscles and tissues which transports food into the gut system for final processing and distribution. The throat closes the top of the breathing pipes, but if the food accidentally enters these pipes, it goes down the "wrong way" and must be coughed up before the body chokes or asphyxiates. As food passes through the body, it is mixed with an unbelievable amount of chemicals, which break it down into small units that can be absorbed into the blood and lymph systems. Some is used for energy, some as building blocks for tissues and cells, and some is stored for future or emergency use. The liver and the pancreas also secrete digestive juices that break down food as it passes through the digestive ducts. Not all that we eat can be digested, so the waste must be disposed of in an efficient way. It may not be a savory ending for the food or drink we thought was so delicious in the mouth, but it is just as important for our health.

I hope that gains your admiration
and sorry on the extension

don't forget
keeeeeep me in your prayers
