Lymphatic System

• Lymphatic System - an organ system that consist of large network of lymphatic vessels, lymph nodes, lymphoid organs, lymphatic tissure and lymph
• Lymphatic Vessels - a thin tube that collects lymph from tissues in different parts of the body
• Lymphatic Vessels - circulate lymph throughout the body
• Lymphatic Capillaries - are tiny vessels that collect excess fluid from body tissue
• Right Lymphatic Duct - lymphatic vessels from the right upper limb and the right half of the head, neck and chest, empties into the right subclavian vein
• Thoracic Duct - lymphatic vessels from the rest of the body, empties into the left subclavian vein
• Thymus - site for maturation for lymphocytes, found in the anterior mediastinum overlying the heart
• Bone Marrow -responsible for lymphocyte production
• Spleen - largest lymphoid organ in the body
• Spleen - filters and cleanses blood of bacteria, viruses, and other debris
• Spleen - stores platelets, acts as a blood resrvoir
• Tonsils - small masses of lymphoid tissue deep to the mucosa
• Tonsils - trap and remove bacteria or other foreign pathogens entering throat
• Palatine Tonsils - located on each side of the posterior opening of the oral cavity
• Pharyngeal Tonsils - located near the internal opening of the nasal cavity
• Lingual Tonsil - located on the posterior surface of the tongue
• Peyer's Patch - small round cluster of immune cell
• Appendix - small tube attached to the beginning of the large intestine
• Mucosa-Associated Lymphoid Tissue - protect the upper respiratory and digestive system from constant attacks
• Lymph Nodes - a kidney shaped, buried in the connective tissue that surrounds them
• Lymph Nodes - filter lymph fluid, trapping foreign substance
• Afferent Lymphatic Vessels - vessels that brings lymph fluid into the lymph node
• Capsule - dense CT that surrounds each lymph node
• Subcapsular Sinus - a space just beneath the capsule
• Trabeculae - extensions of the capsule
• Cortex - the outer region of the lymph node
• outer cortex - outermost part of the lymph node
• Lymph - a clear fluid carried by the lymphatic vessels back to the heart for re circulation
