Liver Immune Function & Cardiovascular System Explained | Kupffer Cells, Antigens & Heart Structure.

How does the liver protect the body from pathogens — and how does the heart circulate blood through the entire body?
In this lesson from the Access to HE Diploma (Medicine), we explore the liver’s immune role, antigen presentation, autoimmune disease mechanisms, and the structure and function of the cardiovascular system.

This lesson is ideal for Access to HE Medicine students, nursing/healthcare learners, and anyone revising human biology.

What You’ll Learn in This Lesson:
This session covers core physiology and immunology topics essential for progression into healthcare and medical studies:
-How Kupffer cells filter pathogens from blood entering the liver
-What antigen presentation is and how MHC Class I & II molecules activate T cells
-Why immune responses sometimes don’t occur even when antigens are present
-How autoimmune diseases like colitis develop
-The structure and function of the heart, including the epicardium, myocardium & endocardium
-How the cardiovascular system transports oxygen, nutrients, and waste.

Key Topics Covered:
-Kupffer cells & hepatic immune surveillance
-Cytokines and immune activation
-Immune tolerance and pathogen evasion
-Autoimmune disease mechanisms (incl. ulcerative colitis, Crohn’s)
-Heart chambers, valves, and tissue layers
-Why the left ventricle is thicker than the right
-The systemic & pulmonary circulation pathways

Who This Lesson Is For:
-Access to HE Diploma (Medicine) students
-Pre-nursing and biomedical science learners
-A-Level Biology students
-Anyone revising immunology or cardiovascular physiology.
