Question

paheli wants to know how food moves in the opposite direction during vomiting

Answer 1

hey there ,,

It is such a great question that during vomiting how does it happen food goes in antigravity direction .

Seems to be interesting,,

let us know why this so and help the girl paheli :-

the irritation occur in stomach just because of bacteria , or food poisoning activates the emetic center of the brain which in turns into an immediate reflex action called vomiting .

so that's why food than goes in the opposite direction often from duodenum to stomach.

and if you confused what is duodenum then let me explain it :-

duodenum :- the part of the small intestine between stomach and jejunum .

hope it helps !!

be brainly together we go far ♥♥

Answer 2

it usually occurs as a precursor to vomiting. local irritation of the stomach such as bacteria, or food poisoning, activates the emetic centre of the brain, which in turn signals an imminent vomiting reflex. food then, moves in the opposite direction, often from the duodenum into the stomach
