Questions Related to food through digestive tract
Water from the undigested food is absorbed mainly in the
-
Stomach
-
Food pipe
-
Small intestine
-
Large intestine
- The large intestine, also known as the large bowel, is the last part of the gastrointestinal tract and of the digestive system.Water is absorbed here from the undigested food and the remaining waste material is stored as feces before being removed by defecation.
- Hence water from the undigested food is absorbed mainly in the large intestine.
- So,the correct answer is 'Large intestine'.
Which of the following is not the function of large intestine?
-
Absorption of water
-
Nutrient absorption
-
Secretion of mucus to lubricate faeces
-
Temporary storage faeces in rectum
- Re-absorption of water and mineral ions such as sodium and chloride.
- Formation and temporary storage of faeces.
- Maintaining a resident population of over 500 species of bacteria.
- Bacterial fermentation of indigestible materials.
- So, the correct answer is "Nutrient absorption".
Feces are stored in which of the following part of the body before excretion?
-
Anus
-
Large intestine
-
Small intestine
-
All of the above
The large intestine, also called as the colon or the large bowel, is the last part of the digestive system in vertebrates. Water is absorbed here and the remaining waste material is stored as feces before being removed by defecation.
The colon extracts .......... from solid wastes.
-
Water
-
Salt
-
Both A and B
-
Sodium
The colon is the last part of the digestive system in most vertebrates. It extracts water and salt from solid wastes before they are eliminated from the body and is the site in which large bacterial fermentation of unabsorbed material occurs. Unlike the small intestine, the colon does not play a major role in absorption of foods and nutrients.
The vermiform appendix is situated at the junction of
-
Large intestine and small intestine
-
Small intestine and duodenum
-
Anus and rectum
-
Stomach and duodenum
The vermiform appendix is also referred to as the vermix or the cecal appendix. It is a blind ended tube connected to the cecum, at the junction of large and small intestine. The appendix is usually located in the right lower quadrant of the abdomen, near the right hip bone.
Vermiform appendix is a part of
-
Alimentary canal
-
Nervous system
-
Vascular system
-
Reproductive system
The vermiform appendix is also referred to as the cecal appendix. It is a blind ended tube connected to the cecum. The appendix is usually located in the right lower quadrant of the abdomen, near the right hip bone. Its position within the abdomen corresponds to a point on the surface known as McBurney's point.
Where do certain symbiotic microorganisms normally occur in human body?
-
Caecum
-
Oral lining and tongue surface
-
Vermiform appendix and rectum
-
Duodenum
Large intestine in man mainly carries out
-
Absorption of water
-
Assimilation
-
Digestion of fats
-
Digestion of carbohydrates
The completely digested food in small intestine is liquid in physical state, so that, absorption of nutrients can be easily carried out but the faeces are reduced in volume and a semi-solid coherent mass because most of the water is absorbed in large intestine.
Which is the incorrect sequence of parts in human alimentary canal?
-
Mouth $\rightarrow$ Stomach $\rightarrow$ Small intestine $\rightarrow$ Oesophagus $\rightarrow$ Large intestine
-
Mouth $\rightarrow$ Oesophagus $\rightarrow$ Stomach $\rightarrow$ Large intestine $\rightarrow$ Small intestine
-
Mouth $\rightarrow$ Stomach $\rightarrow$ Oesophagus $\rightarrow$ Small intestine $\rightarrow$ Large intestine
-
Mouth → Oesophagus → Stomach → Small intestine → Large intestine
After the digestion of carbohydrates in the mouth, food is passed on from mouth to stomach through the oesophagus where the digestion of proteins takes place. The food enters the small intestine for the digestion of proteins, carbohydrates and fats. Finally, it moves to the large intestine which is the last part of the alimentary canal where water is absorbed and undigested/ unabsorbed food is converted into a coherent mass of faeces and ejected from the body through a muscular anus.
Find out the correct sequence for the layers in the wall of ileum from inner to outer side.
-
Mucosa, Circular muscles, Oblique muscles, Longitudinal muscles, Serosa
-
Muscularis interna, Muscularis externa, Submucosa, Visceral peritoneum
-
Mucosal epithelium, Oblique muscles, Circular muscles, Longitudinal muscles, Submucosa
-
Mucosa, Submucosa, Muscularis externa, Circular muscles, Longitudinal muscles, Serosa
- The ileum is the final section of the small intestine in which the remaining of the food is absorbed. The ileum is covered with different layers as it’s structure.
