how many different tissues make up the human body?
396320
The human body is made up of four different tissues:\n1- epithelial: protective and covering\n            secretory\n2- connective: proper\n            bone\n            cartilage\n            blood and blood forming tissue\n3-muscular: skeletal(striated, voluntary)\n          visceral(smooth, involuntary)\n          cardiac(striated, involuntary)\n4-nervous: neurons transmitting the nervous impulse and neuroglia supporting, anchoring and protecting the neurons.

Yes; skin is an organ.  The definition of an organ is a group of tissue that works together for a purpose and is part of a larger system.  The skin is made up of epithelial tissue and is part of the body's immune system.  After all, without it all sorts of sludge would bump into your internal organs!

Skin.\n\nIf you're talking about raw, physical size, then it's around everything else.  Largest!\n\nIf you're talking about weight, it accounts for about 15% of the total body mass, more than any other organ.  Largest!\n\nIf you're talking about surace area, it's about two square metres in size.  Largest!\n\nThough I should say that's just an AVERAGE human.  I seem to recall a case of a woman in Texas who had a sixty pound tumor in her gut.  Totally benign, but it just kept getting bigger and bigger.  She thought she was just gaining weight...

Your skin is your largest organ. It covers your entire body and has a surface area of around 2 square metres. Its thickness varies from 0.5mm on your eyelids to 4mm or more on the palms of your hands and the soles of your feet. In total, it accounts for around 16 percent of your body weight.

Carbon, Hydrogen, and oxygen are what they are essentially made of but there are many different elements in the human body, that come through consumption.

It all depends on the location of the tissue and what organ it functions on.

there are hundreds of muscles in the human body...what exactly are you looking for?

Depending on how picky you want to be, the answer could be A or C.  By definition an organ is always composed of two or more tissue types.  Many organs contain all four major tissue types:  epithelial, connective, muscle, and nervous.  So A is certainly correct.  Since organ systems by definition are composed of two or more organs, they must also be composed of more than one tissue type.\n\nB is not correct because an organelle is a constituent of a single cell, which lies beneath tissues and organs in the hierarchy of organizational levels in complex multicellular organisms.  D could be correct if the organism in question is complex enough to have organs and organ systems.  On the other hand, simple forms of life such as bacteria and protists are also organisms, but being single-celled they obviously have not reached the level of organization at which tissues and organs are found.

Cell, tissue, organ, system, body. Wow, this is 4th grade?\ncells organize and develop into tissues and tissues organize and develop into organs ...\n\nDO your own homework.

Organ is a the correct answer but still if your wondering how it works look back in any basic biology text book where it talks about Levels of Organization.As anyliving thing unicellular to multicellular organism is based on level of organization.\nFor example, ORGANELLE-----CELLS--\n-TISSUE--ORGANs----ORGAN SYSTEM\nAs you already know Tissues are made up of cells rigth so what makes an organ is a group of tissues and in order to have organ system you need different organs a simple example is digestive system where you G.I.tract,stomach,intesitne,pancrea,liver,gall bladder all playing some important role in the functioning of the body.

In biology, an organ (Latin: organum, "instrument, tool") is a group of tissues that perform a specific function or group of functions. Usually there is a main tissue and sporadic tissues. The main tissue is the one that is unique for the specific organ. For example, main tissue in the heart is the myocardium, while sporadic are the nervous, blood, connective etc. (Wikipedia.org)\n\nIn zootomy and dermatology, skin is an organ of the integumentary system made up of multiple layers of epithelial tissues that guard underlying muscles and organs. As the interface with the surroundings, it plays the most important role in protecting against pathogens. Its other main functions are insulation and temperature regulation, sensation and vitamin D and B synthesis. Skin is considered one of the most important parts of the body.(Wikipedia.org)\n\nPretty much the skin is considered an organ because it is a group of tissues speciallizing in a certain task / tasks. For example the skin regulates temperature by using the sweat glands to produce sweat - sweat evaporates and cools the body.
