-
Subgroup of circulatory Sys
- Cardiovascular {Heart & Blood Vessels}
- Blood Vessels {Blood, Veins, & Capulary Sys}
-
*3 Functions of the Lymphatic Sys*
- 1. Collects the Interstital Fluid & brings it bk 2 the blood.
- 2. Fights against infections & protects immunity response
- 3. Absorbs fat from the Intestine & transports it 2 the Blood.
-
*The Lymphatic Sys consists of*...
- - Lymph fluid(Clear), No RBC's
- - Lymphatic Vessels- which carries Lymph???
-
*Lymphoid Tiss*
- - Lymph Node
- - Tonsils{3 types: Palatine, Pharyngeal, & Lingual}
- - Thymus Gland
- - Spleen (blood cells become old & die w/in the spleen)
-
*The Lymphatic Sys*
- - empities in/2 the Circulatory sys
- - there r No RBC's
- - there r No Platelets
- -absorbs fat frm the intestine
-
The 3 types of Cells in the blood???
- 1. Erythrocytes (RBC's)
- 2. Platelets (Thrombocytes)
- 3. Leukocytes (WBC's)
-
2 groups of white blood cells {WBC}
- 1. Agranulocytes
- {-Monocyte
- - Lymphocyte]
2. Granulocytes
-
Major sites of Lymph Node concentration
- - Cervical Region
- - Axillary Region (Arm pit)
- - Mediastinum
- - Inguinal Region (Groin)
- - Adenoids
-
*Spleen*
- - Composed of Lynphatic Tiss
- - Location: UL Quad adjacent 2/near the stomach
- - "Produces, Stores & Eliminates blood cells"
- - Largest Organ in the bdy
-
*Spleen*
- - Destruction of R.B.C's by Macrophage
- - Filtration of the blood
- - Activates B Lymphocytes (B Lymphocytes prod antibodies C-Lymphocytes R phagocytes)
- - Stores blood
-
*Thymus Gland* {4 Components}
- 1. Composed of Lymphatic tiss
- 2. Location: Upper Mediastinum in the chest/bet. the lungs
- 3. Large in childhood but its size decreases in age.
- 4. Helps the body develop immunity & fights against infections
