⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. Formation of tissue fluid * How hydrostatic pressure forces plasma out of capillaries at the arterial end * The role of oncotic pressure and osmosis in reabsorbing water at the venous end * The exchange of nutrients and waste products between blood and body cells 2. Formation and function of lymph * How excess tissue fluid drains into the lymphatic system * The structure of lymph vessels including valves and reliance on muscle contraction * The role of lymph nodes in the immune response and filtering pathogens 3. Comparison of body fluids * A side-by-side comparison of blood, tissue fluid, and lymph * Differences in composition regarding red blood cells, proteins, solutes, white blood cells, and fatty acids *** CHAPTERS *** 0:00 Introduction to body fluids 0:24 Formation of tissue fluid via hydrostatic pressure 3:26 Formation and function of lymph 5:02 Comparison of blood, tissue fluid and lymph *** PLAYLISTS *** https://youtube.com/playlist?list=PLidqqIGKox7VzYfPIVt8T09xOLNcolCe4&si=8JmDajxjtba6rdc3 https://youtube.com/playlist?list=PLidqqIGKox7UZ3mWhbHv2aA_1vnbsfRPq&si=q3hEKdA4v7kbfwMe https://youtube.com/playlist?list=PLidqqIGKox7UTimdJ3eFcnt6xL9GUt2a6 https://youtube.com/playlist?list=PLidqqIGKox7XPh1QacLRiKto_UlnRIEVh&si=orIUwL3o2jOoiYjT https://youtube.com/playlist?list=PLidqqIGKox7X5UFT-expKIuR-i-BN3Q1g&si=DcihOwUkd9oWbbdp https://youtube.com/playlist?list=PLidqqIGKox7WeOKVGHxcd69kKqtwrKl8W&si=Y8MsO-FK948jnxpS https://youtube.com/playlist?list=PLidqqIGKox7UVC-8WC9djoeBzwxPeXph7&si=-7i5Iq7yOeJrhtu6 https://youtube.com/playlist?list=PLidqqIGKox7VKJD2WxRhoKaI6JGLVean8&si=NH_Q1ujhVgACM2FU #Alevel #Biology #study #revision #school #exam #AQA #OCR #Edexcel
