Scene 2

The digestive system is a marvel of biological engineering  that serves as the gateway to our body's nourishment and vitality. 
 It consists of organs that function together to break down the foods you eat into molecules your body can use for energy and nutrients.
 The digestive tract includes the mouth, esophagus, stomach, intestines, and anus. Also called "accessory" organs which include the liver, pancreas, and gallbladder; food doesn't move through these organs, but they secrete hormones and chemicals that are essential to digestion.

[Audio] The main functions of the digestive system are Processing and breaking down ingested food and
Transformation of food into essential nutrients for sustenance and growth..

Processing and breaking down ingested food.
 Transformation of food into essential nutrients for sustenance and growth.

Involves both mechanical (chewing) and chemical digestion (enzymes in saliva).
 Journey through specialized organs like the stomach and small intestine.
 Each organ contributes to the breakdown and absorption of nutrients.
 Plays pivotal role in converting various foods into energy and building blocks.
 Is essential for maintaining optimal health

Parts of the Digestive System

 Mouth

 Small Intestine

 Large Intestine

 Rectum or Anus

 Esophagus

 Stomach

[Audio] The functions of each of thoses parts of the digestive system include
The mouth which is the first activity to take in food through the mouth.
The esophagus which is when The food ingested is broken down into smaller particles
The stomach which is when food travels from your mouth into your digestive system, it's broken down by digestive enzymes that your body can easily absorb.
The small intestines which is when Two types of movement (motility) occur in the stomach: Peristalsis or Segmentation. The contractions occur about every 20 seconds and proceed from the body of the stomach toward the pyloric sphincter. The large intestine which is when The simple molecules that result from chemical digestion pass through cell membranes of the lining in the small intestine into the blood or lymph capillaries.
The rectum or anus which is when The removal of indigestible wastes through the anus, in the form of feces, is defecation or elimination. 

Scene 6

The first activity of the digestive system is to take in food through the mouth. Ingestion

As food travels from your mouth into your digestive system, it's broken down by digestive enzymes that turn it into smaller nutrients that your body can easily absorb. Chemical Ingestion

Two types of movement (motility) occur in the stomach: Peristalsis or Segmentation. The contractions occur about every 20 seconds and proceed from the body of the stomach toward the pyloric sphincter. About 20% of the contractions in the stomach are peristaltic waves.   Movements

The food ingested is broken down into smaller particles, mechanical digestion, which begins in the mouth with chewing or mastication and continues with churning and mixing actions in the stomach.
 Mechanical Ingestion

The removal of indigestible wastes through the anus, in the form of feces, is defecation or elimination. Elimination

The simple molecules that result from chemical digestion pass through cell membranes of the lining in the small intestine into the blood or lymph capillaries. This process is called absorption.

 Absorption

[Audio] The effects on other body systems are
The Cardiovascular System which Ensures the transportation of essential elements throughout the body.
The Nervous System which Coordinates digestive processes through intricate signaling.
The Endocrine System which Influences the release of enzymes and other digestive components.
The Muscular System which Engages in smooth muscle contractions.. 

Scene 7

Cardiovascular System:
 Produces nutrient-rich blood vital for nourishment. Ensures the transportation of essential elements throughout the body.

Nervous System:
 Coordinates digestive processes through intricate signaling. Highlights the mind-gut connection and its impact on overall well-being.

Endocrine System:
 Regulates digestive functions through hormonal mechanisms. Influences the release of enzymes and other digestive components.

Muscular System:
 Engages in smooth muscle contractions. Facilitates the movement of food through the digestive tract.

Overall Impact: Demonstrates the integral role of the digestive system in maintaining harmony among diverse bodily functions.
 Showcases its significance in contributing to overall health.

[Audio] Three effects caused by other body systems are 1- stress because it Triggers the body's fight-or-flight response.
2- NERVOUS SYSTEM DISORDERS because it Affects the coordination of digestive functions and 3- medications because While its beneficial for other conditions, it may inadvertently alter digestive enzyme production. 

Scene 8

STRESS
 Triggers the body’s fight-or-flight response. Negatively impacts digestive processes.

NERVOUS SYSTEM DISORDERS:
 Disrupt intricate signaling; crucial for optimal digestion Affects the coordination of digestive functions

MEDICATIONS
 While beneficial for other conditions, may inadvertently alter digestive enzyme production. Highlighting the impact of pharmaceuticals on digestive processes.

Overall Impact: Recognizing external influences is crucial for understanding how stress, neurological issues, and medications directly affect the digestive system.
 Emphasizes the importance of holistic health management for optimal digestion and overall well-being.

[Audio] % diseases of the digestive system include the Pancreatitis which is inflammation of the pancreas, Diverticular Disease which includes two conditions—diverticulosis and diverticulitis that form in weak spots along the wall of the colon, Colitis which is inflammation of the colon. Sometimes the cause is unknown, or it may be caused by viral and bacterial infections, medications, Crohn's disease, UC, lack of blood flow, pseudomembranous colitis, Peptic Ulcers which Open sores on the inner stomach lining, and Irritable Bowel Syndrome (IBS) which is a Chronic gastrointestinal disorder.. 

Scene 9

Pancreatitis - is inflammation of the pancreas. The pancreas secretes digestive enzymes into the small intestine. It also produces the hormones insulin and glucagon that regulate sugar metabolism.​ Common causes of acute pancreatitis include gallstones and chronic alcohol consumption. Other causes include medications, infections, trauma, tumors​ ​ Diverticular Disease - includes two conditions—diverticulosis and diverticulitis. Diverticulosis is when small pouches, called diverticula, form in weak spots along the wall of the colon. Usually, the diverticula do not cause symptoms. Diverticula can bleed in some people and cause hematochezia (bright red blood passing through the rectum). And sometimes, the diverticula can become inflamed/infected (diverticulitis).​ ​ Colitis - is inflammation of the colon. Sometimes the cause is unknown, or it may be caused by viral and bacterial infections, medications, Crohn's disease, UC, lack of blood flow, pseudomembranous colitis (bacteria causing inflammation of the colon), or necrotizing enterocolitis (serious intestinal disease) in newborns.13​ National Library of Medicine. Colitis.​ There are different types of colitis, including Inflammatory (such as in IBD), microscopic (causes chronic watery diarrhea), pseudomembranous (colon inflammation caused by bacterial overgrowth), ischemic (blood flow is restricted or reduced), and allergic colitis (which usually occurs in infants). ​ ​ Peptic Ulcers - Open sores on the inner stomach lining. Symptoms may include pain and bleeding.​ ​ Irritable Bowel Syndrome (IBS) - Chronic gastrointestinal disorder. Symptoms include abdominal pain and altered bowel habits.​ ​

[Audio] Three EFFECTS OF OUTSIDE/ ENVIRONMENTAL FACTORS ON THE DIGESTIVE SYSTEM include
Crohn's and colitis which are caused by the genes a person has inherited, plus an abnormal reaction of the immune system to certain bacteria in the intestines. Diet which Balanced and diverse diets promote digestive health.
And lastly hydration since Proper water consumption aids in digestion and nutrient absorption. 

Scene 10

EFFECTS OF OUTSIDE/ ENVIRONMENTAL FACTORS ON THE DIGESTIVE SYSTEM​

Crohn’s and colitis are caused by the genes a person has inherited, plus an abnormal reaction of the immune system to certain bacteria in the intestines, probably triggered by something in the environment.

DIET
 Balanced and diverse diets promote digestive health. ​ Adequate fiber intake supports regular bowel movements.

HYDRATION
 Proper water consumption aids in digestion and nutrient absorption.​
 Ensures the smooth movement of food through the digestive tract.

Overall Impact: Diet and hydration directly influence digestive system functionality.​
 Highlighting the importance of mindful eating and staying adequately hydrated for optimal digestive health.

[Audio] Some fun facts are Your body can move your food through the digestive system even while you are standing on your head. It is not connected to gravity because it works with muscles.
When you are first born, you don't have any of the healthy bacteria your system needs to digest food.
Hydrochloric acid in stomach is strong enough to digest metal but will never digest plastic.
The average adult will consume 50 tons of food in a lifetime. That's the weight of 50 cars.. 

Scene 11

Your body can move your food through the digestive system even while you are standing on your head. It is not connected to gravity because it works with muscles.
 You know those laundry detergents you hear advertised that have enzymes to remove stains? Some of those enzymes are the same as those found in your digestive system.
  Platypuses do not have stomachs.
 When you are first born, you don’t have any of the healthy bacteria your system needs to digest food.
 The amount of saliva you produce increases when you throw up to protect your teeth from the acid in your stomach that will come up.
 Hydrochloric acid in stomach is strong enough to digest metal but will never digest plastic.
 The Small Intestine is approximately 22 feet long in length. It is a remarkable surface area for nutrient absorption.
 The average adult will consume 50 tons of food in a lifetime. That’s the weight of 50 cars.

[Audio] In summary, Digestive system is a cornerstone of overall health. Understanding functions—from mouth to small intestine—reveals intricate coordination. Holistic approach to health is crucial for supporting a robust digestive system.
Acknowledging the importance of digestive health contributes to overall health and vitality..
