Digestion & the Liver Lesson 3 | Active Transport & Liver Function

Описание: Egraduate College | Access to HE Diploma (Medicine) | QAA | Laser Learning Awards | WJH511 Digestion and The Liver Lesson 3.

How does active transport work, and why is the liver one of the most important organs in human metabolism?
In this lesson from the Access to HE Diploma (Medicine), we explore cell transport mechanisms, liver metabolism, and the liver’s crucial role in detoxification and immunity.

This is ideal for Access to HE learners, A-Level Biology students, and anyone studying human physiology.

What You’ll Learn in This Lesson:
-This session introduces essential concepts for understanding digestion and human physiology:
-What active transport is and why it requires ATP
-Primary vs secondary active transport (including sodium–glucose co-transport)
-The liver’s role in carbohydrate, fat, and protein metabolism
-Blood glucose regulation: glycogenesis, glycogenolysis & gluconeogenesis
-How hepatocytes detoxify drugs, alcohol, and metabolic waste
-The immune function of the liver, including Kupffer cells
-The difference between functional and structural gastrointestinal disorders.

Key Topics Covered:
-Active vs passive transport (diffusion, osmosis, active transport)
-Sodium–potassium pump and co-transport mechanisms
-Bile production & fat emulsification
-Cholesterol regulation and lipogenesis
-Deamination of amino acids and urea formation
-The hepatic portal vein and why the liver filters blood first
-Kupffer cells: removal of pathogens and immune regulation.

Who This Lesson Is For:
-Access to HE Diploma (Medicine) students
-Pre-nursing & biomedical science learners
-A-Level & foundation biology students
-Anyone revising liver physiology or cell transport.
