Study Notes
Digestive System
- Comprises organs that aid in food digestion.
- Food travels through the esophagus, stomach, small intestine, and large intestine.
Esophagus
- A long tube extending from the throat to the stomach.
- Responsible for moving food from the mouth to the stomach.
Liver
- Produces bile, an acidic juice that emulsifies fats into small droplets.
- Plays a crucial role in fat digestion but does not store food.
Stomach
- A muscular bag that transforms food into a thick mush called chime.
- Mixes food with digestive juices for effective digestion.
Gallbladder
- Stores bile produced by the liver.
- Releases bile into the small intestine when food is present.
Pancreas
- Creates digestive juices released into the small intestine.
- Facilitates the breakdown of fats and proteins into absorbable forms.
Small Intestine
- A long, coiled tube where digestion occurs and nutrients are absorbed.
- Unabsorbed material is sent to the large intestine.
Large Intestine
- A large tube that absorbs water and minerals from waste.
- Eliminates solid waste from the body.
Excretory System
- Responsible for waste removal and maintaining fluid and electrolyte balance.
- Includes processes such as exhaling carbon dioxide, urine production, and sweating to remove excess salt.
Urinary System
- Component of the excretory system that eliminates toxic waste.
- Urine travels from the kidneys through ureters to the bladder and out through the urethra.
Kidneys
- Organs that filter waste from the blood and produce urine.
- Regulate blood salt levels, ensuring balance.
Bladder
- Stores urine until it is expelled from the body.
- The urethra serves as the passageway from the bladder to the outside.
Reproductive System
- Enables the creation of new organisms.
