It is a sensory organ found at the base of the antennae in critters such as millipedes, centipedes and some of the primitive insects and collembolans.\n\nI'm not sure exactly what it detects though.  I think it probably has to do with the mechanical reception/touch sense, activated when the antennae is moved far enough to trigger the organ's sensilla.

This lacks an actual question, but I see what your teacher is aiming at. \nHint: what is the main function of the large intestin? What is reabsorbed there that you wouldn't especially need in aquatic environments?

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.

the nervous system is in the form of our five senses: touch/pain, vision, taste, smell, and hearing. Pain, temperature, and pressure are known as somatic senses. Sensory receptors are classified according to the type of energy they can detect and respond to.  \n\nMechanoreceptors: hearing and balance, stretching.  \nPhotoreceptors: light.  \nChemoreceptors: smell and taste mainly, as well as internal sensors in the digestive and circulatory systems.  \nThermoreceptors: changes in temperature.  \nElectroreceptors: detect electrical currents in the surrounding environment.  \n  I have a cite that has an abundance of information for you on this subject..hope this helps

Well, glands are technically organs. Glands differ from other organs in that their primary function is producing and secreting some hormone/substance

The respiratory system is how you breath in and out. In fact, any organism that participates in gas exchange has a respiratory system. In humans and other mammals, the respiratory system consists of the airways, the lungs, and the respiratory muscles that mediate the movement of air into and out of the body.

Your brain is divided into six major divisions:  the cerebrum, the diencephalon (where the hypothalamus is located), the mid brain, the cerebellum, the pons and the medulla oblongata.  \n\nThe hypothalamus is the center for homeostasis and controls things like hunger, thirst, maintaining body temperature and the control of some reproductive system functions.\n\nThe medulla oblongata is where the spinal cord transitions into the brain.  It is part of the brain stem.  It's job is the control of non-voluntary functions and it also brings sensory information into the brain and helps the cerebral cortex relay information to the spinal cord.\n\nHope this helps...

wouldn't teh functions of the systems be the same for every organisms.  for example the respiratory system is for breathing in both cows and humans and probably for the toad as well.  the circulatory system is for circulating blood in every organsim.  the excretory system extrects toxins and metabolic wastes and the nervous system allows for cordiation of muscles and autonomic behaviors as well as cognitive thinking.  \n\nhowever the real functions of all these organs is SURVIVAL.  SURVIVAL is the driving force of life and you are kidding yourself if you think otherwise.

actually, we have different kinds of taste buds that do different things. some are only there to move food along, others have pores which entrap food and absorb the chemicals to stimulate our sensory neurons. We use our smell as well because all foods have odors that are detected by the odorant binding molecules located near the nose, superior to the roof of the mouth. To sum up your question, it has to do with the odorants binding to the receptors in the nose to send messages to the brain and also the tastant molecules being mixed with saliva to dissolve the taste to send messages to the brain. the cerebral cortex/

Humans have \n1: sight\n2: sound\n3: smell\n4: touch\n5: taste\n\nhorses have those.  what is the sixth?

Scientists are still trying to decipher exactly what is the mechanism by which we taste and smell.  But this we do know: vapors from the substance in question enter the nose and interact with receptor sites there that are keyed to specific responses in the brain.  The combination of the receptor sites that are activated by the vapor generate a signal that the brain interprets as "smell"/"odor"/"aroma" (take your pick).\n\nThink of the various smells you exerience each day -- pears have an ester known as n-amyl acetate that generates that characteristic smell.  Iso-amyl acetate smells like bananas.  \n\nAnd then there are the fouls smelling compounds -- usually containing sulfur -- such as hydrogen sulfide (rotten eggs), or  methanethiol (or methyl mercaptan) -- which is used to generate the smell in natural gas (which is otherwise odorless), or butanethiol -- skunk spray!\n\nAmines typically have a fishy, musty odor.  Fatty acids tend to have a rancid smell.\n\nEach of the chemicals I have mentioned has a variety of chemical structures, and some similarities: the thiols all have a -SH group in the molecule somewhere, which interacts with receptors in our noses to send a signal to the brain of YUCK!! NASTY!!  Most esters have a pleasant, fruity smell -- there, the characteristic group is R-C(O)O-R'.  Primary amines have the R-NH2 structure, secondary amines replace 2 hydrogens with organic groups, and tertiary amines replace all three hydrogens with organic groups, but they all have that nitrogen in there. \n\nI hope that helps.

Hi there !\nWhat do you mean by the question ? \nYou expect somebody to describe the "entire digestion" and the "metabolism mechanism" of the Human body in this column ?\nBetter verify the "Book of Physiology by Guyton" or "Chatterjee"..they have given beautiful descriptions ! \nbest wishes !

Neurons carry msgs through an electrochemical signal\nthree types of neurons r involved in this process...\nSensory (or afferent) neurons: send information from sensory receptors (e.g., in skin, eyes, nose, tongue, ears) TOWARD the central nervous system. \nMotor (or efferent) neurons: send information AWAY from the central nervous system to muscles or glands. \nInterneurons: send information between sensory neurons and motor neurons. Most interneurons are located in the central nervous system.
