hey princess royal....
i'm not much into the medical stuff but are you sure that skin is the largest organ of the body or is it an organ in itself???

I found this in one of my books:

Liver: The liver, often referred to by the word root hepat, is the body's largest glandular organ.

Skin: The skin is the largest organ in the body, weighing about 4 kg. Though it appears uniform in structure and function, its thickness in fact varies, from less than 1 mm covering the eyelids to more than 5 mm on the upper back.


Quote:
Q………Largest organ of human body
So, as per the above question, skin is the right answer.

I was wondering that skin and liver both are glands as well as organs. Then how liver is the largest glandular organ and skin the largest organ? After further reading the book and searching wikipedia the conclusion to which I reach is that liver is the largest internal and glandular organ, whereas skin is the largest organ of the integumentary system and also skin itself is not a gland but there are accessory structures associated with it which includes glands.

So, if asked about the largest internal or glandular organ then that would be liver otherwise the largest organ, on the whole, is skin.

although princess royal has given explanation regarding the largets organ of the body, some points from my side too

skin is considered an organ and NOT a gland. Why to consider it as an organ? Because it is continuous, it responds in a homogenous manner to different injurious agents, often its infectious diseases are not limited to one part of skin but tend to spread to involve whole of the skin. Skin does conntain many glands which again are of various types like sweat glands of ecrine variety, sebaceous glands of holocrien variety and apocrine sweat glands. so skin is viewed AS AN ORGAN OF THE BODY CONTAINING VARIOUS KINDS OF GLANDS AND HAIR FOLLICLES TO ASSIST IT IN PERFORMING ITS VARIOUS FUNCTIONS SOME OF WHICH INCLUDE TEMPERATURE REGULATION AND A BARRIER TO INFECTING ORGANISMS. so these glands in the skin assist it to perform its other functions.

Liver itself is an organ which contains only glandular tissue and its MAIN function is to produce various secretions. SO it is regarded as the human body's largest GLAND.

Yeast turns sugar into alcohol and carbon dioxide. The carbon dioxide makes the bread rise. The alcohol kills any mold or bacteria that had been growing in the grain while the bread rises. That keeps the bread from becoming poisonous. If the bread does not rise, it is like eating a thin piece of wood. Go to a grocery store and pick up a box of matzo. Eat it. That is bread that was cooked without yeast. When the bread has finished rising, it is cooked and ready to eat.

I find these MCQs very confusing, (so I guess I should also cram some effective prayers when choosing an options in the exam hall lol). MCQs at no. 28 and 38 are apparently the same, but there is a world of difference if interpreted correctly. In no. 28, it is asked what atmospheric layer makes radio communication possible, I guess the correct option to choose for such a query would be None of these, cuz if any atmospheric layer was making possible radio communication, it would mean radio communication from space is virtually impossible, something which is not true sincce it is being carried out significantly these days. In no. 38, it is asked which layer is helpful in radio communication, here we can choose Ionosphere, cuz it reflects radio signals and thus have some kind of impact on radio communiction.

So, as per the above question, skin is the right answer.

I was wondering that skin and liver both are glands as well as organs. Then how liver is the largest glandular organ and skin the largest organ? After further reading the book and searching wikipedia the conclusion to which I reach is that liver is the largest internal and glandular organ, whereas skin is the largest organ of the integumentary system and also skin itself is not a gland but there are accessory structures associated with it which includes glands.

So, if asked about the largest internal or glandular organ then that would be liver otherwise the largest organ, on the whole, is skin.
Dont forget the intestine here!!! Small intestine measures over 20 feet and large intestine also measures around 5-6 feet, so there collective size will be over 25 feet tamped down inside what we perceive as stomach.
