duh plz explain we we get hiccups??
Hiccups occur when the diaphragm involuntarily spasms, causing a sudden rush of air into the lungs. The unanticipated inrush of air often momentarily forces the epiglottis closed, and it is the closing of this flap that causes the classic "hiccup" sound.
ok now nxt
can u explain me the counter current mechanism in excretory system
@exuras can u help me to undersstand the term glossopharyngeal i mean i knw its related to tongue but usually get confused i wanna knw it by terminology plz
Do you mean these are counter current mechanisms? *The sphincter urethrae, or urethral sphincter, controlling the exit of urine from the body. *At the anus, there are two sphincters which control the exit of feces from the body (see internal anal sphincter and external anal sphincter). The inner sphincter is involuntary and the outer is voluntary.
well i m atlking abu the mechanism in which salt is absorbed water is released like that
in henele's loop
Glosso: means tongue in greek Pharyngeal: refers to pharynx.
I just wanted to post somthing :P
in henele's loop the mechanism which is running plz explain me
Are you reffering to the Hypersmotic Filter?
Between the glomerulus and the descending helnes loop (where all the H2O is absorbed in this picture) there is a region called called proximal tubuli. this region stands for 70% of the reuptake in the nephrone. Now back to the descending helnes loop, at the descending part only H2O is reabsorbed by Aquaporin-2 channels which are ADH mediated, in the ascending part there are diffrent type of pumps Na-K-Cl cotransporter, which transports the electrolyte back to the bloodstream. Answer to the question of the high osmotic preasure in Descending helnes part region and Ascending part of helnes loop. is due to it's connected with a Vasa recta which creates a osmotic gradient between the two.
Does this answer your question?
ok get it thnx :)
new born babiess dont bear nose hair right den how dey are protected from dust particles?
I would assume it would be the Cilium in trachea. Im just guessing though.
ok one more its not fair to say dat beacuse of presence of simple squamous epithelium we are able to breathe from nose as many part of our body is lined by simple squamous epithelium but we breathe only through nose
am i right or wrong?
We can breath with our mouth aswell, the diffrence would be that the we would loose the primary filter of our respiratory tract since we're bypassing it. But ultimately any opening connected to trachea would suffice to breath. Take into example the procedure you need to do incase someone is suffucating due to a blockage in the trachea, i think it's called Tracheostomy but im not sure.
hmm.. den one qn arises wat makes us to breathe through nose?
we can say dat it i external as well as only side which is lined by simple squamous epithelium?
We breath through out nose instictively aswell as there are numoures benefits to breathing through the nose, breathing from our nose requires much less effort, aswell as our mouth would be dehydrated if we kept which itself has numoures of complication by itself. I've heard this claim before in a lecture i attended, but honestly. I don't know if it's due to the fact of squamous epithelium, i don't remember my cellmorphology that well, perhaps if this squamous epithelium is able to produce a substantial amount of mucosa & nose hair. If so it's true.
*aswell as our mouth would be dehydrated if we kept breathing through it
okheezz.. if u dont get bored i have few more doubt like dis it depends on u?
Go ahead, if i can help i will.
sorry to make u wait i m really sorry for dat
No problem, do you require further assistance?
yes we are not capable to inspire immediately after a long inspiration y so?
Inspire someone else? as in giving an idea?
no inspire ur self like i just taken a long inspiration but immediately i m unable to inspire at d moment
Ah, im going to speculate upon this i don't think there is a direct science behind it imagion the following scenario, you're sitting with a couple of friends remembering a actor you all know whom you're talking about but can't remember his/her name. this is a form of concentrated thinking when your brain tries to narrow down the search to a fraction of your brain where it believes the knowlegde lies, this process is supposed to help you make snabb decissions and remembering things quickly. but in this case it has narrowed it down outside of the relevant region, therefore none of you can think of it. it requires a third person to remember it who doesn't have this "tunnelmemory"(yes i just made that up). inorder to remember it since he could spontaniously access it. same thing applies to associations you make, sometimes you need to learn something or hear something which makes a association between neurons which previously was routed around. You know a subject you can easily grasp what's around it, let's say Krebs cycle for instance. but if you add another component your brain might make associations which would connect it to a completely diffrent process which was believed to be unrelated untill someone gave you an idea (you made an association). Like when people invent things, sitting alone in the dark trying to invent something would almost never work, you need to be subjugated to new knowlegde or perspective to have a creative idea most of the time. These are mere speculations back up with very sparse bits of science. so treat it like an opinion.
so u mean to say der is not valid reason behind it?it only depends wat we tries to think and our brain are made to see that thing like dat way?
Imagion our brain as this "http://www.algonet.se/~friflyg/HKG/bilder/HKG_H6_brainstorming.gif" basically making associations between diffrent things based on previous experiences but on a much more vastly scale with numerous of branches.
Uhm.. auctally disregard what i've said, i just described Epiphany... i sometimes get those two mixed up.
yea but thnx a lot :)
*Imagine That was just a embarrassing typo.. You're welcome, glad i could help... With some of your problems.
You 2 still talking????
Did you need some help aswell Carniel?
Lol no I was just wondering how long you two have been talking. I got on 1st period now its 4th :P
2-3 hours on and off give and take.
I cant do the things you guys do.. I remeber when you were my level now your lv 35 o.o I have to do things like that:O
