Document Summary
Chapter 14- lymphatic system: lymphatic system is a vast collection of cells and biochemicals that travel in lymphatic vessels, and organs and glands that produce them. Include a network of vessels that assist in circulating body fluids. Therefore, are closely associated with the cardiovascular system: lymphatic vessels transport excess fluids away from interstial spaces in tissues into bloodstreams. Without these, fluids would accumulate: special lymphatic capillaries called lacteals absorb fats and transport them to the circulatory system, lymphatic system defend against disease. Lymphatic pathways: start as lymphatic capillaries then merge to form larger vessels that empty out into the circulatory system. Lymphatic capillaries: microscopic, close-ended tubes that extend into interstial spaces, found everywhere, where there are blood capillaries, except the cns. Interstial fluid inside the lymphatic capillaries are called lymph. Tissue fluid and lymph: tissue fluid becomes lymph once it enters lymph capillaries. Lymph formation and function: an increase in tissue fluid hydrostatic pressure moves tissue fluid into lymphatic capillaries.
