Anatomy QIII:QI

Ch. 17-Blood

blood is powered by the action of what organ? the heart
4 functions of blood 1) carries respiratory gases, 2) carries nutrients, 3) carries hormones, 4) regulates body temperature
blood volume for males (in liters) 5-6 liters
blood volume for females (in liters) 4-5 liters
pH of blood 7.35-7.45
viscosity of blood 3.3-5.5
temperature of blood 100.4 degrees F
the liquid portion of blood plasma
plasma is about 90% ____ water
a primary plasma protein: controls osmotic pressure of the circulatory system albumin
a primary plasma protein: transport antibodies globulins
a primary plasma protein: blood clotting elements fibrinogen
three formed elements in blood white blood cells, red blood cells, thrombocytes
white blood cells are also known as leukocytes
red blood cells are also known as erythrocytes
thrombocytes are also known as platelets
5 types of white blood cells, in order from most to least prevalent neutrophils, lymphocytes, monocytes, eosinophils, basophils
this formed element is shaped like a biconcave disc RBCs
this formed element doesn't have any mitochondria RBCs
the most numerous of the formed elements RBCs
this formed element has no organelles or nuclei RBCs
RBC protein which carries oxygen hemoglobin
formed element which protects the body from infectious microorganisms WBCs
circulating leukocytes leave the capillaries diapedesis
type of leukocyte which has a granular-appearing cytoplasm granulocytes
type of leukocyte which does not have a granular cytoplasm agranulocytes
three granulocytic WBCs neutrophils, eosinophils, basophils
two agranulocytic WBCs lymphocytes, monocytes
most numerous WBC which functions to destroy bacteria neutrophils
WBC type which ends allergic reactions, attacks parasitic infections eosinophils
WBC type which secretes histamines, and function in inflammation mediation-start the allergic reaction response and mediate the inflammation basophils
most important cells of the immune system, act against a specific antigen (specific resistance) lymphocytes
two main classes of lymphocytes T cells, B cells
type of lymphocyte which attacks foreign cells directly T cells
type of lymphocyte which multiplies to become plasma cells B cells
the largest of the leukocytes (WBCs), transform into phagocytic macrophages monocytes
formed element which function as clotting cells thrombocytes
a clotting substance (associated with thrombocytes) thrombin
an anti-clotting substance (associated with thrombocytes) antiprothrombin
the process by which blood cells are formed hematopoiesis
the site of blood cell formation bone marrow
all blood cells arise from one cell type: the blood stem cell
this stem cell type gives rise to lymphocytes lymphoid stem cells
this stem cell type gives rise to all other blood cell types (excluding lymphocytes): myeloid stem cells
