- description "Blood and lymph"
- Two of the bodies main fluids are
- Blood and lymph
-
Circulated by the action of the heart
Blood
-
GDoes not circulate but is propelled in one direction to drain into large veins of the circulatory sysem
Lymph
-
Transports oxygen and nutrients to body cells
Blood
-
Removes carbon dioxide and other waste prodocts from body cells
Blood
-
Blood is full of a yellow liquid called
Plasma
-
Scientific study of blood
Hematology
-
Composition of blood
55% plasma, 45% formed elements
-
Formed in bone marrow suspended in plasma
Red blood cells, white blood cells, platelets
-
Red blood cells
Erythrocytes
-
White blood cells
Leukocytes
-
-
Plasma consists of
Water, wastes,dissolved protein, sugar,salt, hormones
-
Plasma proteins
Albumins,globulins, fibrinogen
-
Albumins
60% maintain blood pressure
-
Globulins
36% transport lipids(fats)and fat-soluble vitaminsin blood and function immunity
-
Fibrinogen
4% largest protein and essential in blood clotting
-
-
Erythroblasts
Lose nucleous and turn into mature erythrocyte
-
Complex protein-iron compound that carries oxygen
Hemoglobin
-
-
2 catagories of leukocytes
Granulocytes, agranulocytes
-
Thrombocytes
Platelets clotting the blood
-
Blood types
Due to presence or absence of protein molecules, antigens and antibodies
-
Located on the surface of RBC and generates the formation of antibodies
Antigen, A,B,AB, or o for no antigens
-
Located in the plasma that is "anti" foreign substances
Antibody
-
Why are blood types important
For transplants and transfusions
-
Person who gives blood
Donor
-
If the blood types do not match in the blood transfusion the result is
Agglutination, a clumping of cells
-
Universal donor
O, because it is without antigens
-
Universal blood recipient
Type AB
-
Rh factors
Another antigen like A,B types
-
A mother giving birth to a baby to Rh+ blood has the risk of
Agglutination
-
Mother and baby being+ and - blood types can cause problems for next pregnancy
Rhogam
-
Clotting of blood
Coagulation
-
Several chemicals react and take place forming
Fibrin threads
