    The Digestion Process (Organs and Functions)

  • Digestion definition.
  • What is digestion?
  • The mouth.
  • The pharynx and esophagus.
  • The stomach and small intestine.
  • The colon, rectum, and anus.
  • Three accessory digestive organs (pancreas, liver, gallbladder)
  • What major organs make up the digestive system?

    The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.

    What is the function of the organs of the digestive system?

    These enzymes break down protein, fats, and carbohydrates. The liver has multiple functions, but two of its main functions within the digestive system are to make and secrete an important substance called bile and to process the blood coming from the small intestine containing the nutrients just absorbed.

    What are the major organs of the digestive system and their functions?

    Continued From Above but do not have food pass through them. Accessory organs of the digestive system include the teeth, tongue, salivary glands, liver, gallbladder, and pancreas. To achieve the goal of providing energy and nutrients to the body, six major functions take place in the digestive system: Ingestion.

    What are the parts of the digestive system and their functions?

    Digestive System Parts and Functions

  • Mouth. This is where the process of digestion begins.
  • Pharynx (Throat) The throat or pharynx is a funnel shaped tube that is connected to the mouth.
  • Esophagus.
  • Stomach.
  • Small Intestine.
  • Accessory Organs.
  • Large Intestine (Colon)
  • Rectum and Anus.
  • What are the steps of the digestive system in order?

    Food passes through the digestive system in the following order:

  • Mouth.
  • Esophagus.
  • Stomach.
  • The small intestine.
  • Colon (large intestine)
  • Rectum.
  • What are the two types of digestion?

    There are two kinds of digestion: mechanical and chemical. Mechanical digestion involves physically breaking the food into smaller pieces. Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells.

    What are accessory organs of the digestive system?

    Accessory digestive organ: An organ that helps with digestion but is not part of the digestive tract. The accessory digestive organs are the tongue, salivary glands, pancreas, liver, and gallbladder.

    What are the main organs of the excretory system?

    Organs of excretion make up the excretory system. They include the kidneys, large intestine, liver, skin, and lungs. The kidneys filter blood and form urine. They are part of the urinary system, which also includes the ureters, bladder, and urethra.

    How long does it take for your body to digest food?

    Digestion time varies between individuals and between men and women. After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food.

    What is the definition of digestive tract?

    digestive tract. The series of organs in the digestive system through which food passes, nutrients are absorbed, and waste is eliminated. In higher vertebrates, it consists of the esophagus, stomach, small and large intestines, rectum, and anus.

    What are the three main organs of the circulatory system?

    The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.

    What is the meaning of the digestive system?

    the system by which ingested food is acted upon by physical and chemical means to provide the body with absorbable nutrients and to excrete waste products; in mammals the system includes the alimentary canal extending from the mouth to the anus, and the hormones and enzymes assisting in digestion.

    Is the spleen a part of the digestive system?

    Its other major task is removing or storing certain blood cells. The spleen is not part of the digestive system however is connected to the blood vessels of both the stomach and the pancreas. The spleen is situated on the left side of our body; under the ribs and above the stomach.

    Is a mouth an organ?

    Digestive System. The purpose of the digestive system is to turn the food you eat into something useful for the body. When you eat, your body uses this system to digest food so your cells can use it to make energy. The organs involved in this system include the mouth, stomach, and intestines.

    What is the function of the pancreas in the digestive system?

    Enzymes, or digestive juices, are secreted by the pancreas into the small intestine. There, it continues breaking down food that has left the stomach. The pancreas also produces the hormone insulin and secretes it into the bloodstream, where it regulates the body’s glucose or sugar level.

    What is the function of the large intestine in the digestive system?

    The major function of the large intestine is to absorb water from the remaining indigestible food matter and transmit the useless waste material from the body.

    What cells and tissues are in the digestive system?

    The digestive system contains all four major tissue types, Epithelial, Connective, Muscle and Nervous. Epithelial tissue lines the entire length the digestive tract. It is made up of many different types of cells, including goblet cells that secrete mucus.

    What is the job of the digestive system?

    The job of the digestive system is to break down the food we eat into smaller units called nutrients. The nutrients are then absorbed into the bloodstream and fuel the body’s activities. The MOUTH takes in food and begins the digestive process, which continues in the STOMACH.

    What is the function of the digestive system?

    The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The digestive system is divided into two major parts: The digestive tract (alimentary canal) is a continuous tube with two openings: the mouth and the anus.

    What are the three parts of the small intestine?

    The small intestine has three parts:

  • +Duodenum. The duodenum is the first part of the small intestine. The main role of the duodenum is to complete the first phase of digestion.
  • +Jejunum. The jejunum is the second part of the small intestine.
  • +Ileum. The ileum is the third part of the small intestine.
  • What are the main organs of the digestive system?

    The major parts of the digestive system:

  • Salivary glands.
  • Pharynx.
  • Esophagus.
  • Stomach.
  • Small Intestine.
  • Large Intestine.
  • Rectum.
  • Accessory digestive organs: liver, gallbladder, pancreas.
  • What does the digestive system work with?

    Interacting with Other Systems. The digestive system works very closely with the circulatory system to get the absorbed nutrients distributed through your body. The circulatory system also carries chemical signals from your endocrine system that control the speed of digestion.
