Study Notes
Digestive System
- Food cannot be used directly by body cells
- Digestion breaks down complex food into simple, soluble substances
- These simple substances are absorbed by body cells
- Digestive system: many organs working together to digest food
- Organs involved: mouth, esophagus, stomach, small intestine, large intestine, liver, pancreas, and anus
- Mouth: teeth cut and grind food, saliva breaks down starches into sugar, tongue mixes saliva and food
Digestion Process
- Digestion starts in the mouth
- Teeth break food into smaller pieces
- Saliva mixes with food, breaking down starch to sugar
- Food travels down esophagus to stomach
- Stomach: food is churned and mixed with digestive juices
- Small intestine: digestive juices from liver and pancreas complete digestion
- Nutrients absorbed by blood vessels
- Undigested food enters large intestine
- Water is absorbed from undigested food
- Solid waste (feces) is removed through anus
Importance of Chewing
- Chewing breaks down food into smaller pieces
- Enzymes in saliva start breaking down food
- Smaller pieces are easier to digest in the stomach, and nutrients are absorbed more easily
Function of Bile
- Liver produces bile
- Bile helps digest fats in small intestine
Function of Pancreas
- Pancreas secretes digestive juices
- These juices digest carbohydrates, fats, and proteins
Function of Large Intestine
- Holds undigested food
- Absorbs extra water from undigested material
- Forms stool (semi-solid waste)
- Rectum stores stool before elimination
Function of Anus
- Feces are removed from body through anus
Excretory System
- Living organisms produce waste products
- Toxic waste products accumulate in the body
- Excretion is the process of removing waste products
- Organs involved in excretion: kidneys, ureters, urinary bladder, and urethra
- Kidneys: bean-shaped organs that form urine
- Urine is collected and stored in the urinary bladder
- Urine is removed from the body through urethra
Healthy Habits
- Eat meals at regular intervals
- Chew food thoroughly
- Don't overeat
- Eat in a clean and pleasant atmosphere
- Avoid strenuous exercise immediately after eating
- Maintain regular bowel habits
- Drink ample water, especially first thing in the morning
- Limit foods high in fat, sugar, and processed ingredients
