    1 / -0
    Which among the following are the symptoms of diarrhoea?
    Solution
    Frequent and profuse defecation of liquid faeces is called diarrhoea. It is caused by increased motility and decreased absorption by intestines. Frequent diarrhoea can result in dehydration, sunken eyes, dry mouth and lips, abdominal pain, bleeding from rectum etc. Hence option D is the correct answer. 
  • Question 2
    1 / -0
    A condition in which feaces are discharged from the bowel frequently and in liquid form is termed as:
    Solution
    Diarrhoea is the frequent passage of loose, watery, soft stools with or without abdominal bloating, pressure, and cramps. People of all ages can suffer from diarrhoea; it can be caused by viruses or bacteria. Most common symptom is watery, liquid stool. Along with this, there can be abdominal cramps, fever, bloating, dehydration. etc.
    Therefore, the correct answer is option B.
  • Question 3
    1 / -0
    Wharton's duct is the duct of
    Solution
    Wharton's duct is the duct of the submaxillary or submandibular gland that occurs in the mouth on a papilla at the side of the frenulum of the tongue. The purpose of this duct is to drain the saliva.
  • Question 4
    1 / -0
    Diarrhoea is the ______ leading cause of death in children under five years old.
    Solution
    Diarrhoeal disease is the second leading cause of death in children under five years old, and is responsible for killing around 7,60,000 children every year. Diarrhoeal diseases caused by pathogenic bacteria and viruses are transmitted via the faecal-oral route. The pathogens discharged in the faeces of an infected person may enter the body of another susceptible person through the mouth. This may occur among children ingesting food or water contaminated with human excreta. 
    Therefore, the correct answer is option A.
  • Question 5
    1 / -0
    Most common causative agent for acute diarrhoea is
    Solution
    Acute diarrhea starts quickly and lasts a short time, usually 1 to 3 days. It can last up to 2 weeks. Most cases of acute, watery diarrhea are caused by viruses (viral gastroenteritis). The most common ones in children are rotavirus and in adults are norovirus. 
    Therefore, the correct answer is option A.
  • Question 6
    1 / -0
    Fatty acid and glycerol are transported from intestine mainly through
    Solution
    1. Assimilation means the absorption and digestion of food or nutrients by the body or any biological system. 
    2. Assimilation of fats results in the formation of the end products of digestion of fats ie fatty acids and glycerols.
    3. These are absorbed and taken into the lacteal and later the lymphatic system and then they are transferred to the liver. 
    4. Fatty acid and glycerol can be used to form fats which are stored in the body’s fat deposits e.g. under the skin in the adipose tissue. Hence, the fatty acid and glycerol are transported from intestine mainly through the lymphatic system.
    So, the correct answer is the 'lymphatic system'.
  • Question 7
    1 / -0
    Apart from water what is secreted by the large intestine?
    Solution
    The large intestine also secretes K+ and Cl-. Chloride secretion increases in cystic fibrosis. Recycling of various nutrients takes place in colon. Examples include fermentation of carbohydrates, short chain fatty acids and urea cycling. 
  • Question 8
    1 / -0
    Nutrition includes____________.
    Solution
    Nutrition is the science that interprets the interaction of nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism. It includes food intake, absorption, assimilation, biosynthesis, catabolism and excretion. 
  • Question 9
    1 / -0
    The colon extracts .......... from solid wastes.
    Solution
    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. 
  • Question 10
    1 / -0
    Feces are stored in which of the following part of the body before excretion?
    Solution
    The large intestine, also called as the colon or the large bowel, is the last part of the digestive system. Water is absorbed here and the remaining waste material is stored as feces before being removed by defecation. Thus, Option B is correct.
