what are the similarities and differences between human,frogs,squids,and clams respiratory systems?
477644
Ill just give a few-\nSimilarities: In all cases, it involves bringing O2 into the body, and expelling CO2.  In the case of clams, the intake of O2 and expulsion of CO2 are not linked.\nHumans and frogs have lungs which bring in air.  \nSquids and clams isolate O2 from water\n\nDifferences: Humans have much larger lungs for the body size than do frogs, because humans have much higher metabolism\nHumans and frogs have lungs, the sea animals dont\nHumans, frogs and squids all have a circulatory system.

Breathing, the process whereby an organism (living thing) obtains oxygen from its surroundings, to take part in internal chemical reactions which break down food to release energy. Breathing also usually gives out waste carbon dioxide as an unwanted by-product of these reactions. Breathing is one aspect of respiration, which is a term that includes both physically obtaining oxygen, and also using it in chemical pathways inside cells to release energy—the process of cellular respiration\n\nMany aquatic animals obtain oxygen dissolved in the water by muscle-powered movements, such as when the forward motion of a fish or the pumping actions of its mouth and throat force a flow of water over its gills ( See also Fish). This is underwater breathing. Tiny organisms “breathe” by the process of passive seepage or diffusion of oxygen through their body surfaces. Plants also obtain oxygen by diffusion from the air or water around them, usually into the leaves.

A frog can respire in two ways- pulmonary respiration(through lungs) and cutaneous respiration(through skin).Thus under water it can respire through skin and on land, with the help of lungs.The sklin of a frog is thin and richly supplied with blood vessels to facilitate exchange of gases.It is moist and slimy for protective purposes.

y are u asking homework questions?  Well one similarity is the they are diatomic so in other words they are always H2 or O2 when alone. ohh and the guy below me oxygen is explosive what we breath is mainly nitrogen.  so there i told u

They are different in structure and also in the way that gas exchange occurs. \nIn gills, the water flows in a single direction, and the blood flow in the blood vessels occurs in the opposite direction. Thus optimal gas exchange is achieved (there are good illustrations in textbooks to understand this better). However, to take up oxygen effectively, gills need an enormous surface area, because oxygen is relatively scarce in water. Thus, the gill lamellae are subdivided into smaller lamellae, and these in turn into even smaller projections; these extremely thin laminas are supported in water, but collapse onto each other in air, because of  surface tension and gravity. \nLungs can be of 2 types: the basic model comprises paired sacs, with more or less elaborate inner walls for greater surface area, but also with a surfactant substance that decreases surface tension so that these sacs do not collapse. The air goes in and out of the lungs by way of a single duct, thus there isn't a continuous flow of oxygenated air. Less efficient, but air has so much oxygen that it works anyway. The exception are the lungs of birds, in which the blood vessels are at right angles with respect to air flow, and the latter is continuous and unidirectional. \nAll respiratory surfaces need to be moist, and lungs are no exception. However, in this case the moisture is _inside_ the body, and the body surface is still mostly impermeable. \n\nThird choice... that would be perhaps the tracheae of insects. Aquatic arthropods have lungs of different types, and terrestrial chelicerates do have special gills too. But insects have a different system: ducts that pierce the body wall and project inwards, taking oxygenated air directly to the tissues (no participation of the circulatory system).

A brian is defined as the principal ganglion of an animal's nervous system.  A ganglion is a collection of nerve cells that process information.  It receives in formation from nerve fibers that extend throughout the body of an animal and also may be affected by a variety of hormones.  The level of complexity of a central ganglion roughly parallels the anatomical complexity of the organism as a whole. \nMulticellular organisms need to coordinate the activities of their individual cells.  Most animals use a system of specialized cells, called neurons, to help coordinate the activities of different tissues. The exceptions include sea sponges, which are a rather like a loose collection of cells.  Other primitive animals such as jelly fish, do have neurons organized into networks. \n\nWhile all of these organisms can sense their environment in some way and respond to it, they do not have brains.  Only animals with distinct body cavities possess brains.  This includes life forms as diverse as earth worms, clams, fish, insects, birds, and of course, human beings.  As a general rule, animals with more tissue types have more intricate brains. \n\nBoth invertebrate and vertebrate animals can have complex brains.  Of the invertebrates, squid an octopuses have the most developed brains, in part to process information coming from their highly sophisticated eyes.  A medium sized octopus will have a brain containing over 100 million neurons, and can show learning behavior.  Still, this is a far cry form mammalian brains that contain on  the order of 10 billion neurons. \n\nOur human brains are remarkably facile in learning, dependable in recollecting and can be quite creative in thinking and expressing a variety of thoughts and emotions.

Most mammals have pretty much the same nervous system set up as we do.  \n\nThere might be a few differences in the number and size of some of the major sensory nerve bundles.  Humans don't have much in the way of an olfactory nerve, while other critters would have much larger nerves to carry more information.

none.  They are mollusks.  They do have those hard little beaks, but those are not bones any more than a bird's beak is a bone.

Cephalopod transtates literally to Head Foot.  THey are a class of mollusks that include squids and octopi.

Human health \n\nEating clams, mussels, oysters or scallops contaminated by red tide can cause severe illness and even death to humans. Federal regulations now require toxin monitoring programs that are implemented during red tide outbreaks. While some illnesses related to shellfish consumption occur, the highly cautionary regulations have been quite effective. \n\nAerosols from red tides can produce respiratory ailments. However, no studies have been done to determine if there are long-term consequences of inhaling potent neurotoxins from algae. Also, it is difficult to assess long-term effects of acute exposure among tourists who leave the area. \n===============================================\n\nPlease see a doctor right away! In the mean time, don't eat any sea creatures and protect yourself from common colds. The treatment that I found includes infussion of antibiotics and being in an oxygen tank.\n\nGood luck!

Reproduction System:  Depending on the species some clams are either females or males.  Both the eggs and sperms are released into the water.  Some clams are hermaphroditic which means the clam has both male and female reproductive organs.  In the species that fertilization takes place externally, the zygote develops into a swimming larva, trochophore (Alexander 439).  In some freshwater clams the young is carried inside the female's gills for a period of time.  Reproduction can occur at two different times of the year.  "long term brooders or winter brooders" spawn basically in August to October and carry the young all winter long.  The "short tem brooders or summer brooders" spawn during the summer and the young is carry for a few weeks.  After a certain period of time are discharge from the female mussels and become parasites on fish fins, gills, and external surfaces.  This stage may last up to six weeks (Harris and Gordon 2)

About 1%\n\nNearly 99 percent alike in genetic makeup, chimpanzees and humans might be even more similar were it not for what researchers call "lifestyle" changes in the 6 million years that separate us from a common ancestor. Specifically, two key differences are how humans and chimps perceive smells and what we eat.

No, all animals do not breathe like us.\n\nBirds for example have an very different arrangement to their lungs. You and I have to take a breath in to absorb air and then take a  breathe in and then breathe out to expel it. A bird takes a breath in and a breath out at the same time. Every breath for a bird absorbs air and expels used air at the same time. That makes birds far more efficient at breathing than a human and also makes them far better at singing since they can make sound even while breathing in if they wish.\n\nMost land animals don't even have lungs and don't need to draw air into their bodies. Instead they absorb air directly  through their skin.\n\nEven something as similar to us as a frog can breathe mostly thorough its skin. All frogs have lungs that they can use to breathe but the lungs are used mainly for when the whether is dry. Many species of frogs have very small lungs, and the lungs can be surgically removed without having any effects at all on the frog. So long as the skin is kept wet a frog is perfectly capable of breathing through its skin.\n\nAnimals like slugs, snails and worms also breathe through their skin.\n\nIn the case of worms they have no other organs to breathe with. They are entirely dependent on their skin to breathe and the skin has to be kept wet or they suffocate.\n\nSnails breathe not just through their skin but also through a set of gills tucked up under the shell. It might seem strange that a land animal would use gills to breathe, but snails evolved from sea animals and have retained the same method of breathing.\n\nSpiders also use what is really a modified gill in order to breathe. The gill consists of a set of plates, like the pages in a book, hanging inside a pouch on the back segment of their body.\n\nInsects can't breathe very much through their skins, but they don't breathe through their mouths like we do. They instead have a series of holes along their sides that they use to breathe through. Those holes are connected to a series of pipes that run right through the animal. Imagine a person with holes in their side the size of the cardboard roles from toilet paper. You could see right into the holes all the way to the heart or guts, and those holes are the way that air gets into the body. Insects use pretty much that method. It's pretty , weird but it works for them.\n\nThere are many other ways that land animals breathe, but those are the main ones. Either they breathe through their skins like frogs or worms do, the have modified gills like snails or spiders or they have tubes running through their bodies as insects do.
