OBJECTIVES LAYERS IN VASCULAR WALLS CLASSIFICATION OF VESSELS VARIATION IN MICROVASCULATURE LYMPHATIC SYSTEM Introduction Multicellular Organisms Need 3 Mechanisms . and Exchange of Materials. Learning Outcomes. Capillaries allow exchange of substances with tissues. . Pressure filtration of fluids through capillary walls. Similarity of tissue fluid and blood plasma with the exception of plasma proteins. Tissue fluid supplies cells with glucose, oxygen and other substances. Carbon dioxide and other metabolic wastes diffuse out of the cells and into the tissue fluid to be excreted . The lymphatic system consists of:. lymphatic vessels which drain excess fluid from the tissues and return it to the cardiovascular system. lymphatic organs such as lymph nodes, tonsils, spleen, thymus gland and red bone marrow that assist in immunity .
