What is excretion?
differentiate between bonyfish and birds in terms of excretion
Answers:
Excretion is the "process of eliminating from an organism waste products of metabolism and other materials that are of no use. It is an essential process in all forms of life. In one-celled organisms wastes are discharged through the surface of the cell. The higher plants eliminate gases through the stomata, or pores, on the leaf surface. Multicellular animals have special excretory organs. In humans the main organs of excretion are the kidneys and accessory urinary organs, through which urine is eliminated (see urinary system), and the large intestines, from which solid wastes are expelled. The skin and lungs also have excretory functions: The skin eliminates water and salt in sweat, and the lungs expel water vapor and carbon dioxide."
poo
i thought it was poo so im confused
a number two
Sweating and 'going to the toilet'
This question is excretion!
something eliminated by the process of excretion that is composed chiefly of urine or sweat in mammals including humans and of comparable materials in other animals, characteristically includes products of protein degradation (as urea or uric acid), usually differs from ordinary bodily secretions by lacking any further utility to the organism that produces it, and is distinguished from waste materials (as feces) that have merely passed into or through the alimentary canal without being incorporated into the body proper.
or:
a waste product (as urine, feces, or vomit) eliminated from an animal body
excretion is term used to describe something exiting something else - such as poo, or excreting sweat, excreting a foul smell - pardon me!
Excretion is the removal of metabolic wastes from the body.
It's to do with the removal of nitrogenous waste from the animals system as urine/urea/ureic acid.
I can't remember the specifics though, sorry.
the elimination of waste products
excretion is the removal of the waste products of metabolism.
Excretion is the process and excrement is the product.Excrement is crap, use your imagination.

In mammals, for example, the two major excretory processes are the formation of urine in the kidneys and the formation of carbon dioxide (a human's most abundant metabolic waste) molecules as a result of respiration, which is then exhaled from the lungs.
The waste products are eliminated by urination and exhalation respectively. In urination, Hormone control over excretion occurs in the distal tubules of the kidneys as directed by the hypothalamus.
Perspiration is another excretory process which removes salts and water, although the primary purpose is cooling.
In insects, a system involving Malpighian tubules is utilized to excrete metabolic waste. Metabolic waste diffuses or is actively transported into the tubule, which transports the wastes to the intestines. The metabolic waste is then released from the body along with fecal stuffs.
Many people misuse the term excretion as a sort of euphemism for defecation, and use excrement for feces, but this medically improper.
By the way tell you some jokes, and the jokes goes:
-Doctor! I have a serious problem, I can never remember what i just said.
-When did you first notice this problem?
-What problem?
One more joke:
A guy calls his vet and says "What should I do with my cat?Vet says "What do you mean? Guy says "I had a leak in my lawnmowers gas tank and the cat drank the gas. Then the cat began to run around and around the yard, climbed a tree. then fell out of the tree stiff. Vet says "Is the cat dead? Guy replies "nope he ran out of gas.
At least there is more to this question than a childish sense of humor! But, as far as the difference.. sorry .I don't know.
It is the body"s way of getting rid of solid waste.

All animals that live in freshwater must cope with a continual inflow of water from their hypotonic environment. In order to maintain homeostasis of its extracellular fluid (ECF), the freshwater fish must excrete this excess water.
Contraction of its heart (powered by ATP) provides the pressure to force the water, small molecules, and ions into the glomerulus as nephric filtrate. The essential ingredients are then reclaimed by the tubules, returning to the blood in the capillaries surrounding the tubules. The blood in these capillaries comes from
the glomerulus (as in humans) and also from
the renal portal veins which drain the posterior part of the fish's body.
After solute reabsorption is complete, the urine is little more than water. Most of the nitrogenous wastes (including large amounts of ammonia, NH3) leave by diffusion out of the gills. So, the kidney is mostly a device for maintaining water balance in the animal, rather than an organ of excretion.
Birds
Bird kidneys function like those of reptiles (from which they are descended). Uric acid is also their chief nitrogenous waste.
Most birds have a limited intake of fresh water. However, they need filter only enough to wash a slurry of uric acid into the cloaca where enough additional water is reclaimed to convert the uric acid into a semisolid paste. (It is the whitish material that pigeons leave on statues).
Actually excretion is not poo, that is egestion. Excretion is when the body get rid of waste products from metabolism, urine, carbon dioxide from the lungs and sweat from the skin. Poo on the other hand is never absorbed into the body or involved in metabolism.
I'm afraid I don't know much about excretion in fish or birds specifically.
