Task 1

loke_yu_fei — 2025-07-21 07:28:46 UTC

Without the stomach, the digestion of fats, carbohydrates and proteins will be affected.

While it is still possible, digestion of proteins would take a longer time. Nutrients such as fats and carbohydrates would not particularly be affected as they are not absorbed by the stomach

Task 1

choo_peiqing — 2025-07-21 07:29:29 UTC

The stomach partially digests proteins by proteases. Without the stomach present, the digestion of proteins will be affected. However, the stomach does not digest carbohydrates or fats, so the digestion of these will not be affected.

task 1

jaydon_kwang — 2025-07-21 07:29:52 UTC

Without stomach it will be harder to digest the proteins but the other nutrients shouldn't be affected as the stomach doesn't digest them

TASK 1:

If the stomach was not there, digestion would be badly affected because the stomach helps break down proteins using acid. Without it, digestion would take longer to in the small intestine. Carbohydrates would not be affected much, since they are mostly digested in the mouth and small intestine. Fat digestion would also still happen in the small intestine, but it would be slower without the stomach's help.

Task 2

loke_yu_fei — 2025-07-21 07:33:02 UTC

Chicken rice containing proteins and carbohydrates and soya milk would be broken down by the mouth through chewing mixed with saliva
and travels through the gullet into the stomach where gastric juices further break it down and passes into the small intestine.
With the help of enzymes the nutrients fully absorbed and the remaining waste enters the
large intestine absorbing all the water turning into solid waste and is eliminated through the anus.

Task 1

teo_sze_rui — 2025-07-21 07:34:19 UTC

The digestion of carbohydrates and fats will continue normally as the mouth and intestine have carbohydrases and lipases to digest carbohydrates and fats quickly.

However, the digestion of proteins will be slower as without the proteases in the stomach, the small intestine is the only organ with proteases to digest proteins fully.

Task 1

nyan_thu_ta1 — 2025-07-21 07:34:31 UTC

Without a stomach, digestion would be much worse. The body wouldn't break down carbohydrates, proteins, and fats properly. This is because the stomach strats the process of breaking down proteins and helps mix food with substances that help digest fats. Without stomach, less of these nutrients would be absorbed, leading to health problems from missing important nutrients.

Task 1

denisengxl — 2025-07-21 07:34:43 UTC

The stomach is important as it is involve in the initial breakdown of food and without it, it will lead to digestive issues and nutritional deficiencies. Carbohydrates and fats will not be affected. However, proteins are partially digested by the stomach and without the stomach the digestion of the proteins will be affected.

Task 1

kieora_tok_en_ning — 2025-07-21 07:35:00 UTC

The stomach primarily digests proteins. Without it, digestion of proteins will be significantly affected. The digestion of carbohydrates and fats might not be affected as much.

Task 1

ziptoi8 — 2025-07-21 07:37:32 UTC

Carbohydrates and fats do not get digested in the stomach so the body absorbing sugar and fatty acids and glycerol would not be a problem if the stomach is not present in the digestive system. However, the body absorbing amino acids would be a problem. The stomach digests proteins using proteases made by the stomach to digest small enough so that the small intestine can futher digest the protein into amino acids that are able to be absorbed into the body. Without the stomach, this wouldn't be possible and the body would not receive amino acids from the protein.

Task 1

Hana, Zi Le

Without a stomach, protein digestion would slow down a lot since it needs stomach acid and enzymes. Carbs would mostly be fine, and fats would be harder to digest but still broken down in the intestines. Overall, digestion of proteins and fats would be less efficient.

task 1

linuxontop2011 — 2025-07-21 07:38:18 UTC

if the stomach is not there there will be no digestive juices to digest food. and the stomand primarily digest protein hence our bodies will be very small and we wil die

task 2

zhihann — 2025-07-21 07:38:41 UTC

the food is churned and broken down into smaller pieces in the mouth. food is transported from the mouth to the stomach in the gullet. food is churned and mixed with gastric juices, breaking it down into smaller pieces in the stomach. small intestine receives partially digested food from the stomach and, with the help of digestive juices from the liver, pancreas, and its own walls, breaks down food into its basic components. large intestine absorbs water and electrolytes from undigested material, forming feces. stool is stored until it's ready to be expelled from the body in the rectum. anus is where solid waste (feces) exits the body. Amylase breaks down starch and other carbohydrates into simpler substances. Protease breaks down proteins into amino acids. Lipase breaks down fats into fatty acids and glycerol

Task 1 (Eik Kiat)

tan_eik_kiat — 2025-07-21 07:39:47 UTC

The digestion of proteins will be affected due to the stomach being the main organ that breaks down proteins. If the stomach is removed, the person will have a deficiency of protein.

2025-07-21 07:41:41 UTC

the mouth first digests the rice a little and chews up everything into smaller pieces to aid with digestion, the food is then swallowed into the gullet to be transported to the stomach while still getting digested by the swallowed saliva, in the stomach protein, the chicken and soya beans is mainly digested by the enzyme in the hydrochloric acid, proteases. The other food is also digested a little bit here,after about 2 to 3 hours, the food will be transported into the small intestine where fat is mainly digested by the lipases and also broken down by bile, all the other types of food are also digested further here,they are then transported into the large intestines which absorb excess water and waste,the remaining that remains undigested becomes waste that is stored in the rectum and eventually comes out through the anus

task 1

zhihann — 2025-07-21 07:42:08 UTC

protein digestion would not be as good, as there’d be no acid or pepsin to start the process. Fats would also be harder to break down without the stomach’s mixing, making overall digestion slower and less efficient.

Task 2

jaydon_kwang — 2025-07-21 07:42:18 UTC

When he eats the chicken rice the carbohydrates in the rice gets digested by the mouth and the chicken gets digested in the stomach soya beans have protein which is digested in the stomach as well the vegetables fibre don't get digested and becomes waste

Task 2

anggun_nabilah_yusri — 2025-07-21 07:43:15 UTC

When the boy eats chicken rice and drinks soyabean milk, digestion starts in the mouth , where chewing breaks the food into smaller pieces and salivary amylase begins breaking down starch into maltose. The food then moves through the esophagus to the stomach , where it is mixed with acid and pepsin to digest proteins from the chicken and soy.

Next, in the small intestine , enzymes from the pancreas and bile from the liver help break down starch, protein, and fats into glucose , amino acids , fatty acids. These nutrients are then absorbed into the bloodstream. The undigested food goes into the large intestine where water is absorbed. Finally, waste is removed through the rectum and anus. There is carbohydrate, protein, fats, vitamin and minerals from the chicken rice and the soyabean drink.

Task 2

ang_yu_qi_xyra — 2025-07-21 07:45:49 UTC

The rice and chicken contain carbohydrates, proteins, and fats. The soy milk provides additional protein and carbohydrates. The mouth starts breaking down carbohydrates and the stomach focuses on digesting protein. The small intestine absorbs the majority of the nutrients for all types of foods. Protease breaks down proteins into amino acids and lipase breaks down into fatty acids and glycerol.

Task 2

teo_sze_rui — 2025-07-21 07:49:38 UTC

Strong teeth and jaw muscles in the mouth cut and crush the food into smaller pieces. The starch from the rice gets partially digested by the carbohydrases in the mouth into partially digested carbohydrates.
As the food travels town the gullet, the starch continues to get digested by the carbohydrases.
Food in the stomach gets churned into smaller pieces.
Proteins from the chicken and soya bean milk gets partially digested by the proteases in the stomach into partially digested proteins.
The small intestine fully digests carbohydrates from the rice into simple sugars, proteins from the chicken and soya bean milk into amino acids and fats from the food into fatty acids and glycerol.
The fully digested food then gets absorbed into the bloodstream by the small intestine. Digestion ends here.
The large intestine absorbs water and mineral salts from the indigestible fibre collected from the small intestine.

task 2

goh_zi_xuan_janice — 2025-07-21 07:50:14 UTC

First, digestion starts in the mouth with the mouth secreting salivary amylase which helps to digest some starch from the rice into simple sugars. The undigested food then travels down the gullet towards the stomach. The stomach has proteases to help digest proteins from the chicken into amino acids in the undigested food. Then, the undigested food heads towards the small intestine while the gallbladder secretes bile produced by the liver which helps break the lipids from the oil into smaller molecules. Then the undigested food goes down to the small intestine where proteases, lipases and carbohydrase is secreted to digest the undigested proteins into amino acids, the undigested carbohydrates into glucose and the undigested lipids into fatty acids and glycerol. Finally, the rest of the undigested food goes into the large intestine where water and minerals are absorbed and the undigested food like the dietary fibers from the vegetables becomes feces stored in the rectum and out the anus.

task 2

lian_jun_wen_cruz — 2025-07-21 07:55:46 UTC

mouth, gullet, stomach, small intestine, large intestine, rectum and anus
the mouth digests carbohydrates and fats. the gullet transports food from the mouth to the stomach. the stomach digests protein, carbohydrates and fats. the small intestine absorbs protein, carbohydrates and fats. the large intestine absorbs water and electrolytes to form stool. the rectum temporarily stores the stool. the anus expels the stool.
protease breaks protein into amino acids. carbohydrates is broken down into glucose and the fat is broken down into glycerol

task 2

kieora_tok_en_ning — 2025-07-21 07:56:12 UTC

The chicken rice and soya bean milk are chewed and mixed with saliva, which contains enzymes that start breaking down carbohydrates
The food mixture enters the stomach. The stomach muscles churn and mix the food with strong digestive juices to digest the protein.
Nutrients like glucose , amino acids , and other smaller molecules are absorbed into the bloodstream through the intestinal walls.
Undigested food is then eliminated from the body from the large intestine

Task 2

nyan_thu_ta1 — 2025-07-21 07:56:23 UTC

1.Mouth
The boy chews the food. Teeth break it into smaller pieces.
Saliva in the mouth starts to break down the rice (which is a carbohydrate).

2.Esophagus

The food and drink are swallowed.
They move down the esophagus (a long tube) into the stomach. Muscles push the food down in a wave-like motion.
