Thoracic duct (drains 3/4 of the body) and opens into the left innominate vein.  ‫كلية طب الفم‬ ‫واألسنان‬ ‫‪General Anatomy GDN131‬‬  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Fluid passes from arterial capillaries To tissues Venous capillaries Excess fluid drained into lymphatic capillaries Lymphatic vessels  ‫كلية طب الفم‬ ‫واألسنان‬ ‫‪General Anatomy GDN131‬‬  ‫كلية طب الفم‬ ‫واألسنان‬ ‫‪General Anatomy GDN131‬‬  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 A- Thoracic duct )of the body 3/4( B- Right lymphatic Duct )of the body 1/4(  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Lymphatic System Lymph capillaries: they are wider and thinner than blood capillaries.  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Lymphatic System  Lymph vessels: they follow the blood vessels and are known by their beaded shape due to the presence of valves along the course of the vessels to direct the lymph fluid into blood.  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Lymphatic System  Lymph nodes: are stations of filtration along the lymphatic vessels, they are present mainly in the axilla, groin and neck.  ‫كلية طب الفم‬ ‫واألسنان‬ ‫‪General Anatomy GDN131‬‬  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Lymphatic System  Lymphoid tissues: collections of lymphoid tissues other than lymph nodes e.g. tonsils, adenoid and nodules of the spleen.  There are no lymphatics in the nervous system (c.s.f), bone marrow and the eye.  ‫الفم‬ ‫طب الفم‬ ‫كليةطب‬ ‫كلية‬ ‫واألسنان‬ ‫واألسنان‬ ‫‪General Anatomy GDN131‬‬ ‫‪Quiz‬‬  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Spleen  It is a lymphatic organ, lies beneath the left dome of the diaphragm, behind the Stomac stomach and h Spleen protected by 9th , 10th , 11th ribs.  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Protected :by 9th , 10th, 11th ribs  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Spleen  It has a surface related to the diaphragm (diaphragmatic surface) and a visceral (medial) surface related Stomac to the Spleen stomach, left h kidney and pancreas.  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 t has 2 surfaces Hilum Visceral surface Diaphragmatic surface  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Spleen  Visceral surface related to:  Stomach  Pancreas  Left kidney Stomach Spleen  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Left e as nc r Kidney Pa  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Spleen  The hilum of the spleen is present on the visceral surface.  ‫الفم‬ ‫طب الفم‬ ‫كليةطب‬ ‫كلية‬ ‫واألسنان‬ ‫واألسنان‬ General Anatomy GDN131 Sum up  Components:  Lymph fluid  Lymph capillaries  Lymph vessels  Lymph nodes  Lymphatic tissues  Spleen  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Formative Assessment  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 - Complete the following statement by suitable words:  The lymph vessels are characterized by their ……………. shape due to the presence of ……………. along their course.  ‫كلية طب الفم‬ ‫واألسنان‬ General Anatomy GDN131 Thank you
