- The pylorus is the bottom part of your stomach.

Vital Organs
- Brain. The human brain serves as the body’s command and control centre, receiving and transmitting signals to other organs via the nervous system and secreted hormones.
- Heart. The human heart is in charge of pumping blood throughout our bodies.
- Kidney. The kidneys’ function is to remove waste and excess fluid from the blood. ...

What organs can affect the digestive system?
We all know the importance of a healthy digestive system in the human body. The system comprises the esophagus, stomach, small intestine, large intestine, rectum, and the anus. These hollow organs are interconnected to form the digestive system, that helps the body in breaking down the food we eat and absorb the nutrients in it.

Food must first be digested and absorbed. Main Organ: Mouth.
What are the 4 main structures of the digestive system?
Regions of the Digestive SystemMouth.Pharynx & Esophagus.Stomach.Small and Large Intestine.
Which of the following is considered the major digestive organ of the body where the majority of absorption occurs and digestion is completed?
The small intestine carries out most of the digestive process, absorbing almost all of the nutrients you get from foods into your bloodstream. The walls of the small intestine make digestive juices, or enzymes, that work together with enzymes from the liver and pancreas to do this.
Where are the major organs of digestion located in the body quizlet?
Right upper quadrant (RUQ) major organs are: Liver, Gallbladder, portion of the colon & small intestine. Left upper quadrants (LUQ) principal organs are: Stomach, Spleen, portion of colon & small intestine.
What are the three main parts of the digestive system quizlet?
They are digestion, absorption, and elimination. The digestive system starts at the mouth when food gets bitten into smaller and smaller pieces and is mixed with saliva.
What are the major functions of the digestive system?
Motility, digestion, absorption and secretion are the four vital functions of the digestive system. The digestive system breaks down the foods we eat into energy our bodies can use.
What are the 3 main functions of the digestive system?
There are three main functions of the gastrointestinal tract, including transportation, digestion, and absorption of food. The mucosal integrity of the gastrointestinal tract and the functioning of its accessory organs are vital in maintaining the health of your patient.
Which of the following is the main function of the digestive system?
The digestive system breaks down food into nutrients such as carbohydrates, fats and proteins. They can then be absorbed into the bloodstream so the body can use them for energy, growth and repair.
Why is small intestine the most important organ of digestive system?
The small intestine is the most important organ of the digestive system because it carries the major digestion and absorption of digestion food. Food is exposed to several digestive enzymes in small intestine only. Ileum of the small intestine has a large surface area that helps in the absorption of digested food.
Which of the following organs receives digested food directly from the small intestine quizlet?
The ileum absorbs nutrients from digested food and empties the waste into the large intestine.
Is the large intestine the colon?
The longest part of the large intestine (a tube-like organ connected to the small intestine at one end and the anus at the other). The colon removes water and some nutrients and electrolytes from partially digested food.
What organs make up the digestive system quizlet?
What are the eight organs that make up the digestive system? The mouth, esophagus, stomach, small intestine, large intestine, gallbladder, liver, and pancreas.
Can you identify the major organs of the digestive system quizlet?
the cecum, colon, and rectum collectively.
How many organs are in the digestive system quizlet?
Seven organs of the digestive system.
What chapter is Digestive System MAP?
Start studying Chapter 23 Digestive System MAP. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
What are the folds of the small intestine?
The circular folds of the small intestine enhance absorption by causing the chyme to spiral, rather than to move in a straight line, as it passes through the small intestine.
What is the function of mucus in the digestive system?
Produces mucus that protects parts of the digestive organs from the effects of powerful enzymes needed for food digestion
What are the accessory organs of the digestive system?
Each accessory digestive organ aids in the breakdown of food ( (Figure) ). Within the mouth, the teeth and tongue begin mechanical digestion, whereas the salivary glands begin chemical digestion. Once food products enter the small intestine, the gallbladder, liver, and pancreas release secretions —such as bile and enzymes—essential for digestion to continue. Together, these are called accessory organs because they sprout from the lining cells of the developing gut (mucosa) and augment its function; indeed, you could not live without their vital contributions, and many significant diseases result from their malfunction. Even after development is complete, they maintain a connection to the gut by way of ducts.
What are the two main groups of the digestive system?
The first group is the organs that make up the alimentary canal. Accessory digestive organs comprise the second group and are critical for orchestrating the breakdown of food and the assimilation of its nutrients into the body. Accessory digestive organs, despite their name, are critical to the function of the digestive system.
What is the function of the peritoneum?
The function of the digestive system is to break down the foods you eat, release their nutrients, and absorb those nutrients into the body. Although the small intestine is the workhorse of ...
How does the digestive system work?
As is the case with all body systems, the digestive system does not work in isolation; it functions cooperatively with the other systems of the body. Consider for example, the interrelationship between the digestive and cardiovascular systems. Arteries supply the digestive organs with oxygen and processed nutrients, and veins drain the digestive tract. These intestinal veins, constituting the hepatic portal system, are unique; they do not return blood directly to the heart. Rather, this blood is diverted to the liver where its nutrients are off-loaded for processing before blood completes its circuit back to the heart. At the same time, the digestive system provides nutrients to the heart muscle and vascular tissue to support their functioning. The interrelationship of the digestive and endocrine systems is also critical. Hormones secreted by several endocrine glands, as well as endocrine cells of the pancreas, the stomach, and the small intestine, contribute to the control of digestion and nutrient metabolism. In turn, the digestive system provides the nutrients to fuel endocrine function. (Figure) gives a quick glimpse at how these other systems contribute to the functioning of the digestive system.
Which part of the alimentary canal is made up of skeletal muscle?
In the most proximal and distal regions of the alimentary canal, including the mouth, pharynx, anterior part of the esophagus, and external anal sphincter, the muscularis is made up of skeletal muscle, which gives you voluntary control over swallowing and defecation.
Which muscle is in a constant state of tension, pulling the mucosa of the stomach and small intestin?
Muscularis mucosa —This thin layer of smooth muscle is in a constant state of tension, pulling the mucosa of the stomach and small intestine into undulating folds. These folds dramatically increase the surface area available for digestion and absorption.
What are the four layers of the alimentary tract?
Starting from the lumen and moving outwards, these layers are the mucosa, submucosa, muscularis, and serosa, which is continuous with the mesentery (see (Figure) ).
Which organ is a favored site of body entery by bacteria?
The mouth is a favored site of body entery by bacteria, and the presence of the tonsils (lymphocyte and macrophage filled organs) is very effective in preventing many pathogensfrom getting further into the digestive tract.
How does mechanical digestion work?
Mechanical digestion breaks food down physically by squeezing and pummeling it. Chemical digestion uses enzymes to break the chemical bonds of the food molecules and release the units.
