ENDOCRINOLOGY
The Endocrine system is another essential system of the body which consists of ductless glands mainly the adrenal, hypothalamus, pineal, thyroid, parathyroid, pituitary, islets of Langerhans in the pancreas, ovaries and testes which secretes the hormones directly in the blood, that are necessary and significant to the body development, processes and growth. They go to the different organd in the body and maintain the balance and equilibrium for normal processes to take place.

Endocrinology, on the other hand, is a study and branch of medicine dealing with these hormones along with their specific functions, development, physiological roles and significance in the body. It explains and discusses the endocrine glands further and their secretions which affects the body processes in different ways which sometimes lead to disorders. That's why it is also a branch of Science which aids in the diagnosis and treatment of the disorders that may arise.
One of the important hormones is the TSH (Thyroid Stimulating Hormone) which enables the thyroid glands to produce or secrete more hormones. Along with these are the adrenaline, calcitonin, Parathyroid hormone, Triiodothyronine (T3) and many more wherein all are secreted by different glands and has specific and different functions. They bind to specific receptors in the organ as their target.
TOXICOLOGY
As to the meaning of the word, toxic is an adjective that describes a dangerous, bad and sometimes deadly product or anything that may cause adverse and harmful effect. This also applies to another branch of Science called the Toxicology wherein it tells of the different chemicals and drugs that may poison, destroy and greatly affect living organisms. As to knowing the speicific chemicals that have these effects, it also aims to determine and study their nature, the main cause, their content, and the treatment.

Toxicology is a broad field which is used to describe the cellular and biochemical effects of the toxins, testing animals so as to know the effects it will have on humans and to define toxin exposure and its levels. The dose and effects of the chemical plays a very important role in determining the level of exposure of a person. Potentially dangerous chemical contaminants that affects humans may be found from pesticide residues in fruits and vegetables, metals in seafoods, plastic container contaminants, methanol and some in drugs.
As it is commonly taught in the laboratory, there are various chemicals that may be poisonous in the body that's why careful handling is strictly advised to students so as to avoid accidents. Exposure to toxins through accidents is commonly encountered as compared to other causes which may be suicide, or abuse and addiction. The victim may be exposed through inhalation, ingestion or transdermally.
DRUG TESTING
One of the most prevalent cause of crime and illegal actions since then is the use of prohibited drugs. Addiction is the main cause of the abuse due to the relieving effect it gives the person upon intake which makes him/ her ask for more and more. However, any drugs that are mistakenly handled and used gives a bad effect and can be so harmful to the user. It may affect his mental behaviors and moreso, his physical health and his decision making abilities. It damages the body parts and organs by and by, little by little.
This is the reason why usage of the drugs and prohibition of illegal drugs is highly stressed and emphasized. Along with this, drug test was made so as to detect and find those who are in the influence of these dangerous and deadly drugs. Drug test is an analysis of different specimens such as urine, saliva, blood, sweat, etc. which aids in determining the presence of any drug metabolites. Urinalyis is the most commonly used test type on drug testing.
Each of the drugs have different detection periods. Some can be easily obtained after 24 hours with the use of urine as the specimen like ecstasy and alcohol. Some takes longer times and period to be detected depending on the specimen used. In performing drug test, the employer must follow a procedure and steps from the collection on to the delivery of the result.

Hello Paul,
There are some portions I would like to talk to you about, see me on MOnday. The links are good, you could also add some videos which are not copyrighted. You Tube can be a good source.
hey there paul.. this is the first time i browsed this because i was busy reading the newer posts.. and i find this also very informative.. Toxicology might be a good subject ha? you are taking this up in school? From where? AUF? i heard this school is a very good campus and the teachers are very outstanding also. I see how they have come up with this activity.. It is very good especially to us who would like to find something very good from the net.. Thanks to the idea of making up this blogging activity on Toxicology :) They help a lot..
And also,, the very thing i love about your posts is that they are not just plain medical terms.. You try to dig deeper and try to be felt by your audience.. that makes reading your posts more interesting.. keep it up
as i was browsing your old posts, i have noticed that i havent posted comments on two of them so here goes :) this one is really very full of substance.. i like reading this one as it draws out in me an interest in toxicology.. because this is also a must.. to know.. since we should beware of the toxins that might pile up inside our bodies and then intoxicate our organs... so we should know all these.. very helpful :) GODbless you more...

since toxicology is a broad field and it doesnt only talk about prohibited drugs, we still can learn a lot of things aside from the simple drugs and other known drugs we see and hear of. But in dealing with present issues, we know how important it is to really know more about these drugs therefors this blog is very very helpful to make us understand better..
please keep posting :)
primarily,, you also can teach us about the organs and parts of the body that fights toxins right? and we will learn from you about all the things we need to know how to prevent us from being intoxicated.. cool :) Great.. God bless
plus, bryan is right.. :) You do not only write to inform.. you write to be felt by your reader and it makes you more interesting to hear out... You will be a very good writer in time.
