Which statement about digestion is true?
Digestion is a form of catabolic activity because it involves the breaking down of food into smaller sizes that can be absorbed as nutrients by the body while releasing energy through the process. The statement about digestion which is true is that, gastric juice helps to process food into chyme.
Which statement is true concerning the digestion of carbohydrates?
Which statement is true concerning the digestion of carbohydrates? -Carbohydrates must be digested in the large intestines. -Carbohydrates are broken down into monosaccharides before being absorbed.
Which is true about digestion and absorption of food?
Hence, the correct answer is option D, i.e., Amino acids are absorbed in the intestine with the help of carrier ions of Na+.
Which of the following occurs during digestion?
The digestive system ingests and digests food, absorbs released nutrients, and excretes food components that are indigestible. The six activities involved in this process are ingestion, motility, mechanical digestion, chemical digestion, absorption, and defecation.
What are the 2 types of digestion?
Digestion is a form of catabolism or breaking down of substances that involves two separate processes: mechanical digestion and chemical digestion. Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion.
What are the three phases of gastric activity?
The process of gastric secretion can be divided into three phases ( cephalic, gastric, and intestinal ) that depend upon the primary mechanisms that cause the gastric mucosa to secrete gastric juice.
Where does digestion start?
Digestion begins in the mouth. The food is ground up by the teeth and moistened with saliva to make it easy to swallow. Saliva also has a special chemical, called an enzyme, which starts breaking down carbohydrates into sugars.
Where does fat digestion begin?
Fat digestion begins in the stomach. Some of the byproducts of fat digestion can be directly absorbed in the stomach. When the fat enters the small intestine, the gallbladder and pancreas secrete substances to further break down the fat.
Where is bile stored in the body?
About 50% of the bile produced by the liver is first stored in the gallbladder. This is a pear-shaped organ located directly below the liver. Then, when food is eaten, the gallbladder contracts and releases stored bile into the duodenum to help break down the fats.
Which is correct regarding digestion and absorption of food in a woman?
So, the correct answer is ‘ Fructose and amino acids are absorbed through intestinal mucosa with the help of carrier ions like Na+’.
Which of the following is an accessory organ of digestion?
The salivary glands, liver, gallbladder, and pancreas are not part of the digestive tract, but they have a role in digestive activities and are considered accessory organs.
How is digestion regulated?
The brain and the endocrine system control digestive processes. The brain controls the responses of hunger and satiety. The endocrine system controls the release of hormones and enzymes required for digestion of food in the digestive tract.
What are the 7 steps of digestion?
The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation. Some chemical digestion occurs in the mouth.
What are the six processes of digestion?
The six major activities of the digestive system are ingestion, propulsion, mechanical breakdown, chemical digestion, absorption, and elimination. First, food is ingested, chewed, and swallowed. Next, muscular contractions propel it through the alimentary canal and physically break it down into tiny particles.
What are the 4 stages of digestion?
There are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food.
