The Path of a Steak dinner
This storyboard does not have a description.
Today I will be having a dinner of steak, brocoli, and baked potato. I sure am excited! Let me show you exactly how the food goes through my body and gives me energy.
I put the food into my mouth, where it get mechanically digested through my biting as well as chemically digested by amylase, an enzyme in saliva that turns starches into sugars.
I swallow the food, where the esophagus takes it down from my throat to my stomach. Peristalsis is where the esophagus contracts rhythmically to push thef food down. Inside my stomach, muscle contractions break it down even smaller, and then the acidity of the stomach allows the enzyme pepsin to dissolve it into a soupy mix. Then it moves into the small intestine
The small intestine also continues with mechanical digestion and peristalsis. Now, my food gets the final digestion. The pancreas makes enzymes that will digest carbohydrates, proteins, and fats, so basically everything in my meal. It also makes the small intestine slightly basic for enzyme perfection. The liver makes bile to digest fats. Excess bile is stored in the gallbladder. These nutrients now go through the villi to my blood.
The large intestine encompasses the colon, rectum, and appendix (the latter of which is basically useless). Bacteria in the colon produce some vitamins for us. The colon absorbs water from the chyme, which is what the villi can't absorb. The rest turns into fecus and gets released through the posterior end of the body.
In the end, here are some nutrients the foods gave me. I got carbohydrates, fats, proteins (mostly from steak), vitamins and minerals. Some vitamins I got were D and E from brocoli, B6 and C from potato, and Thiamine and Niacin from steak.
