*** WHAT'S COVERED ***

1. The two main roles of the digestive system:

“

The goats of YouTube science

— @fizzylit6637

* Digestion: The breakdown of large food molecules (carbohydrates, proteins, lipids) into smaller, soluble molecules.

* Absorption: The movement of these small molecules from the digestive tract into the bloodstream.

whose here for year 10 mocks

— @bhhgrfjb33btf4hf

2. The journey of food through the digestive organs and their functions:

* Mouth: Role of teeth and salivary glands (producing amylase).

— @Baharm.8

* Oesophagus (Gullet).

* Stomach: Role of muscular walls, pepsin (protease enzyme), and hydrochloric acid.

“

Actually I took a 3 month medical course but tell me why this free 8minute video was way more helpful?) Thank you for your hard work

— @enfp9812

* Small Intestine: Where most digestion and absorption occurs, involving enzymes like carbohydrase, protease, and lipase.

* Pancreas: Production of pancreatic juices containing digestive enzymes.

— @muhammadibrahim-m9d2b

* Liver and Gallbladder: Production of bile by the liver and its storage/release by the gallbladder to neutralise stomach acid and emulsify lipids.

* Large Intestine: Absorption of excess water.

Monotonous

— @MuhammadibraheemhayatBosan

* Rectum and Anus: Storage and egestion of faeces.

3. Adaptations of the small intestine for efficient absorption:

not the liver being neglected in this video

— @TheQweenBacon
