For discussing the functions of different structures of all organisms.
Sure. That condition gives a feedback signal to nerves in brain that gives us a hungry feeling, and also gives an impulse to nervus vagus which one of its target is stomach. Then we decided to eat to get more energy, which will improve the blood circulation, which then will send more oxygen to brain.
i have a question, when we are to much get oxygen in our brian we should get dizzy and maybe lost of control, right? not make our hunger felling dissapear, right?
the explanation of Dr. Stein " Sure. That condition gives a feedback signal to nerves in brain that gives us a hungry feeling, and also gives an impulse to nervus vagus which one of its target is stomach. Then we decided to eat to get more energy, which will improve the blood circulation, which then will send more oxygen to brain. " is quite reasonable, but from that i'm will thinking that if the enough oxygen in brain not occurs, we will get hungry.
hey why do not you make the detailed explanation. i mean the effect for those 3 factor on hunger felling.
so that no one will thinking that if the three factor not occurs the hunger felling won't arise in our head.
hey, if we are lact of oxygen do not we will take a deep breath to get the oxygen? not eating some thing?
Do you think that by taking a deep breath is enough to supply the oxygen? Even if it is enough, you need some energy to contract and relax your respiratory component. How can you provide energy if you do not have enough source? How can they be converted into energy if you do not have oxygen? This is a circle thing that you cannot split it into pieces.
Why did not I make explanation in detail? Because none asked me to do, then I thought everyone knows about it. If I am not mistaken, some friends already describe it somewhere and I see that is enough. Why do not you try to explain it for us?
the source is our body self. if we do not body to be our source of energy -i.e.muscle, any living organ except bone and nerve cell- we won't alive, right? that's why docter give oxygen first before infuse because the passient have body.
hey now you want me talking about energy.(T_T)
correct, but i think when human already has body the second step is air(oxygen)
back to hunger felling.
okay i only detailed and modified your 3 answers above.
first is no more food in our stomach, so that no new glucose is gained.
then this make a low level of glucose that stimulate hypotamus to make "hunger" (there are sensor in our body, i cannot describe it for you because of my few knowlegge, but i can said this evidence has relation with our cell. when blood is lact of glucose the intersitium also lact of glucose. then our cell won't runs properly, i mean it is not fast as normal. as the result the cell will known by sensory that it is not work properly (this is a complex mechanism, for futher info pls read book titled by receptor)nervous system is trying to solve this matter by "hunger".
keyword are homeostasis, internal sensory, metabolism (maybe C-RNA are involve)). this is the most take part for arise hunger felling. but, when we are trying to hang on to not to eat something the felling,hunger, will dissapear for a few minutes. maybe we use our hormone to avoid the lact of glucose in our blood-glikogen in lever is converted to glucose.
after several time HCl in our stomach hurt our self, so that the hunger felling increases.then if this goes for a long time we get maag.(the same as me) yes, that why we eat at periodical time. our stomach produce HCl at those time where is the time we often eat.
about Oxygen, as your and my post above it is still needed to do aerobic metabolism. but, if Glucose is converted the CO2 will occurs. CO2 is can attract hemoglobin more good than oxygen, so our brain will lact of oxygen. you know that our nerveous cell is the most active so it has more mitocondria, because has many mitocondria the cell need more oxygen to do metabolic reaction-aerob. the suplay is from our breath.
again we have body as our source of energy.
so no food, lact of glucose is the main part that makes us fell hungry, so i think your answer is good but too much. about oxygen, when we are not hungry then we do not get any oxygen are we fell hungry? no, i think.lact of oxygen makes us breath not eat
am my first post today makes you angry?
i do not want any one angry... so i'm sorry.
