 So here is the next topic that is excretion and the animal in animals excretion in animals So this word excretion it should not be confused with the defecation So excretion you had that is the removal of in fact the nitrogen is waste or the nitrogen waste. Yeah, I'm only I'm only Eurya a uric acid so excretion in fact that can be defined Broadly as the elimination of metabolic waste products from the animal's body Joe Surplus and nitrogen your toxic substances are particularly nitrogenous products. Yeah In key removal or the hand key removal you have oh that always that occurs through water So it's a it's a donor cheesy awesome a regulation or excretion. Yeah, they are associated with each other Now these products they include carbon dioxide and water Yeah, this is surplus water. Yeah, oh yeah, the carbon dioxide key removal that is through the respiratory other surfaces as breakthrough surfaces or Yeah, Joe carbon dioxide or water, Joe. Hey Yeah, I'm nipple. Yeah, we all know. We are familiar about it. Yeah, that's spirit the products You have respiration a result pay Joe substance the substance is up Joe Surplus substances but the carbon dioxide or water So it's key removal key. Yeah, so that is the respiratory sucks Now excess nitrogen is Produced as just a a excess night. Oh, you can see it. Yeah, that's all the protein key metabolism The nitrogenous products Or yeah, nitrogenous products. They may be ammonia jury or your case the ammonia from the from the de-amination of Amino acids de-amination and it's Amino acid can that there is a NH2 group Amino group is key removal and then it is converted into then Ammonia then Julia and juric acid or or now some nitrogen is excreted as Criminine or treating the donor Joe. Yeah, again nitrogen nitrogen containing very complex compounds Now the excretion of nitrogenous phase is usually associated with the regulation of water Or your water balance kisati is key association Now the nature of excreted products is determined mainly by the availability of water to the organism and That is its habitat, but it that means k that means give o animals Joe complete Joe aquatic Whoa, whoa toe. I'm thought baby. That is ammonia excreted Okay, I'm only a key removal killie a lot of water is required for water. It's the It's moving in the body and it's coming out of the body along with them ammonia Or a pretty much as animals and Joe can relatively Dry conditions where I think or whoa you're you're not Okay, you're your head is relatively again as compared to monia is less toxic So it's not water. I mean, he said for it's removal, but in this key, but I'll water key is worth has Roor Lakin as compared to aquatic animals as compared to aquatic animals They need less amount of water There was give out a kitchen is as animals and you can terrestrial as a bird saying or Boat desert animals you hand whoa They prefer to synthesize jury case it you can get your ass a bill is toxic Visually, they need very little amount of water. Do you? Environment it is key removal. You have nitrogen base key removal. It is associated The ammonia is extremely toxic toxic and must be eliminated rapidly Because it's key toxicity here says about the idea that a good 2% Ammonia a good rabbit the blood may hold the rabbit So yeah, it's not toxic So so it's key removal our body is your aquatic animals and Jesse a monia brought to you You'll see what is key removal? So Julia is produced by animals who have Moderate water supply such as amphibians and humans and many other animals next is the jury case it and It starts they are ideal products for the terrestrial organisms for example insects and birds the insects to hang there are so many insects you say Water pit they will need a car Yes, it's a boy. I see animal grains me right thing So they do not take water as such but he won't metabolic water. Go he's the mall. I'll cut the Metabolic water go he's the mall. That is we used So our boss are birds. You have a booby. What come honey, please? Or he's leave you Rick is it when I didn't even key shittings key under there's a lot of of the crystalline form which is what we call the uric acid. So this is the introduction of excretion in animals. So this is all about.
