What happens when cooked meat passes through gastric juice?
The gastric juice dissolves the fatty part of the meat, therefore starting the fat's chemical digestion into fatty acids in the stomach.
Is gastric acid the secretions in the gastric juice produced by the stomach?
Gastric acid is part of the "juices" produced by the stomach.
What is the main component of gastric juice?
Parietal cells in the stomach secrete hydrochloric acid (HCl) which break bonds between compounds.Other cells produce intrinsic factor, a glycoprotein whose presence in the digestive tract is required for the absorption of vitamin B12in the small intestine.Chief cells in the stomach secrete pepsinogen which is converted by the acid in the gastric lumen to pepsin, an enzyme that breaks down proteins.The pylorus is a part of the stomach that produces gastrin. The pyloric glands also contain D cells, which release somatostatin, a hormone that inhibits the release of gastrin.
What breaks down food into molecules that the cell can use?
It is broken down into small molecules by a complicated process called digestion. Digestive enzymes like saliva, gastric juice, intestinal juice, bile, pancreatic juice all play a part in digesting and breaking down the food to small molecules so that it can get absorbed by the small intestine
Secretions from the stomach promote the digestion of what?
If you mean what is stomach acid in chemical terms? HCL.
Is saliva a gastric fluid?
No, saliva is not a gastric fluid. Saliva is produced by the salivary glands in the mouth and helps with the initial stages of digestion by breaking down food particles. Gastric fluid, on the other hand, is produced in the stomach and consists of hydrochloric acid and digestive enzymes.
Does the small intestine have mechanical or chemical digestion?
Yes, in part. Chemical digestion occurs in the mouth (saliva), stomach (gastric acid) and small intestine. The nutrients are mostly absorbed in the walls (lining) of the small intestine.
Name the first of THREE parts of your body that have glands that aid in digestion?
One part of the body that has glands aiding in digestion is the stomach, which contains gastric glands that secrete digestive juices including hydrochloric acid and enzymes.
What roll does the gastric mill play in digestion in a crayfish?
In crustaceans, specifically decapods such as the crayfish, the stomach is divided into two parts: the first, or anterior part is called the "gastric mill". The gastric mill is lined with chitinous teeth which grind up coarse food particles. The posterior part of the stomach acts as a filter to keep coarse particles from entering the digestive glands, where absorption takes place.
What is the description of the inner wall of the stomach of the fetal pig?
The inner wall of the stomach of the fetal pig is lined with gastric mucosa, which contains gastric pits leading to gastric glands. These gastric glands secrete enzymes and mucus that aid in digestion. The lining also has rugae, which are folds that allow for expansion of the stomach.
What important roles stomach perform during digestion?
The stomach secretes these fluids:•Gastric juice: acidic liquid secreted from the stomach; it contains hydrochloric acid, pepsin, water, and other compounds•Hydrochloric acid: very acidic, starts to denature proteins, converts pepsinogen into active enzyme pepsin (assist in protein digestion), kills many bacteria and germs that may have entered the body•Pepsin: proteins and fats enter the stomach largely unchanged, begins digestion of protein and activates other GI enzymes needed to digest your meal•Gastric lipase: one enzyme responsible for fat digestion, not very much produced so little digestion occurs•Mucus: thick whit fluid that protects the stomach lining from being digested by HCl and pepsin•the stomach also mixes and churns (more mechanical digestion) food until it becomes liquid chyme•Stomach has three bands of muscles; longitudinal, circular and diagonal•Pyloric sphincter regulates the release of chyme from the stomach into the first part of the small intestine, the duodenum
Which part of the alimentary canal is the most acidic?
The stomach is the most acidic part of the alimentary canal. It has a low pH due to the presence of gastric acid, predominantly hydrochloric acid, which helps with digestion and kills bacteria in the food.
