What is the function of the blood?
transport, protect and regulate
What is the components of blood?
rbcs, wbcs, and plasma
What is plasma?
proteins, water and solutes
what percentage of our blood is plasma?
the blood cells include:
erythrocytes, leukocytes and platelets
Where does blood come from?
Hematopoiesis-is the production of blood cells (bone marrow (red) produces cells
Stem cell- is a non-differentiate immature blood cell (can make rbcs, wbcs and platelets)
what is erythrocytes?
red blood cells
what is the function of rbcs?
carry and exchange oxygen and carbon dioxide between the lungs and the body tissues
what carries the oxygen in the blood?
hemoglobin-red protein pigment
what is thrombocytes?
what are platelets?
they aid in blood clotting, maintain capillary integrity by working as plugs to close opening in capillary wall
immediate local vasoconstriction occures in response to injury
collagen from the inner lining of a blood vessel comes in contact with platelets and causes them to get sticky and clumpy
inactive plasma proteins circulate then become activated by either the intrinsic or extrinsic pathway of coagulation
What is the function and loacation of the spleen?
store wbcs and platlets, very vascular, located next to stomach under rib cage
during fetal development
removers old, defective rbcs using phagocytes, recycles iron for re-use by the bone marrow
contains large supply of lymphocytes and monocytes
30% of platelet mass is stored in the spleen
what are the nursing implications for a patient with a spleen laceration?
what are the nursing implications for a patient following a splenectomy?
weaken immune system
what is the function of the lymph system?
*carries fluid from the interstitial spaces to the blood
*produces antibodies-specialized proteins produced in response to invasion by a foreign substance
*returns excess interstital fluid to the blood, preventing lymphedema
developmental defect, AV malformations
results from outside factor compromising the functioning of lymp system.
infection of the lymph system (not a chonic problem just infection)
what nursing measures will required for a patient experiencing lymphedeman ot lymphangitis?
water, walking, low salt intake
*a filter for the blood- rids the body of many end products in the circulation
*very vascular, store the extra iron
what are the nursing implications for the patient with cirrhosis or liver failure?
patient have higher risk for anmeia, eat diets high in iron ex green leafy veggies
containing products- inhibits platelets aggregation, increases bleeding time, can cause petechiae
inhibits platelet aggregation (clotting)
anemia, leukpenia, thrombocytopenia
anemia, leukopenia, neutropenia, thrombocytopenia
blood doesn't clot!
Complete blood count, laboratory blood test
CBC test detect?
consists of several test in one
will detect problems such as anemia, infection, leukemia, platelet abnormalities
