What is a complete blood count? What can it tell you? It?s a test that gives information about the kinds and numbers of cells in the blood, a combination of totals from the red blood cell count, white blood cell count, erythrocyte indices, hematocrit, and differential blood count. A CBC helps the doctor chec
Ratio of the volume of the red blood cells to the blood volume hematocrit

Lymphatic vessels pick up fluid in the ___ and return it to ___ in vessels near the ___ Lymphatic vessels pick up fluid in the tissue and return it to blood in vessels near the heart
Lymphatic capillaries are more or less permeable than blood capillaries? More. They can pick up fluid and protein left in the tissue as blood leaves capillary bed.
Fluid in the tissue spaces that carries protein molecules and other substances back to the blood Lymph
Difference btw afferent and efferent lymphatic vessels Afferent (4 or 5) carry lymph toward the center of a lymph node. Efferent (one) carry lymph from the center of a lymph node to outside.
Different tonsils and location Pharyngeal (Adenoids, Roof ofÿpharynx), tubal (roof of pharynx), 2 Palatines (at each rear of the throat), Lingual (Behindÿthe tongue)
What symptoms would indicate a person has an infection? Fatigue, loss of appetite, weight loss, fevers, night sweats, chills, aches and pains.
What factors put a person at risk for an infection or decrease a person?s immunity? Decreased immune system secondary to disease, compromised circulation secondary to peripheral vascular disease, compromised skin integrity secondary to surgery, or repeated contact with contagious agents
What components of the blood are responsible for fighting infection? WBC-Lymphocytes
What amount of blood is pumped by an adult heart every minute? 5-6 Liters
Functions of the lymphatic system Transport excess fluid from the interstitial spaces to the circulatory system; Protect the body from infections
