Which of the following is not true of the digestive system?
The statement that is NOT true about the digestive system and its contribution to homeostasis is: The digestive system is responsible for monitoring the oxygen and carbon dioxide amounts in the blood and tissues. The correct answer is B.
Which statement is true about digestion?
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 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 4 of the 6 processes of digestion?
2. Digestion Is a 6-Step Process. 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.
What is the main function of the digestive system?
What organs make up the digestive system? Your digestive system is uniquely constructed to do its job of turning your food into the nutrients and energy you need to survive. And when it’s done with that, it handily packages your solid waste, or stool, for disposal when you have a bowel movement.
How does age affect digestion?
Aging puts the body at higher risk for an assortment of health ailments and conditions. With age, many bodily functions slow down, including your digestive tract — it just might not work as efficiently or as quickly as it used to. The muscles in the digestive tract become stiffer, weaker, and less efficient.
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.
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.
How does chemical digestion process happens in the stomach?
They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. As this happens, your pancreas releases enzymes and a bicarbonate buffer that reduces the acidity of digested food.
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 5 steps of digestion?
The five steps which occur in the process of nutrition in animals are Ingestion, digestion, absorption, assimilation, and egestion. Ingestion is the process the food is taken inside through mouth and broken down by teeth and initial digestion takes place in the mouth by saliva.
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.
How do we digest food step by step?
Your digestive system, from beginning … to end
- Step 1: Mouth. To more easily absorb different foods, your saliva helps break down what you’re eating and turn it into chemicals called enzymes.
- Step 2: Esophagus.
- Step 3: Stomach.
- Step 4: Small Intestine.
- Step 5: Large Intestine, Colon, Rectum and Anus.
What is the process of digestion step by step?
Digestive Processes The processes of digestion include six activities: ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation. The first of these processes, ingestion, refers to the entry of food into the alimentary canal through the mouth.
What is the best maintains intestinal health?
5. Which of these best maintains intestinal health? You didn’t answer this question. Based on the age and gender of a person, the Institute of Medicine recommends 21 to 38 grams of fiber daily, with at least 3 servings of whole-grain foods.
