Human bio chapter 6 Flashcards
three functions of blood in human body
transportation, defense, and regulation
formed elements of the blood
produced in red bone marrow,
red blood cells
white blood cells
platelets
describe composition of plasma
91% water and 9% salts,
solutes help maintain osmotic pressure
(salts act as a buffer)
3 types of plasma proteins
Albumins, Globulins, and Fibrinogen
why is the plasma, albumins important
help from blood leaking from vessel
why is the plasma, globulins important
help fight infections, and transports molecules in blood
why is the plasma, fibrinogen important
its inactive, but when activated it forms blood clots
how do RBCs transport oxygen and carbon dioxide
RBCs are specialized for oxygen transport, they contain protein (hemoglobin) and will bind to oxygen and iron groups
structure of RBC how its well suited for gas transport
no nucleus, shape allows them to squeeze through small capillaries and maximize surface area
function of white blood cells
(leukocytes) fight infections
granular leukocyte
Neutrophil, Esoihophil, Basophil
agranular leukocyte
Lymphocyte, monocyte
disorders with WBS
leukemia- a group of cancers that affect blood and bone marrow
structure and function: Neutrophils
Comes from Myeloblasts
contains granules
phagocytizes pathogens
structure and function: Lymphocytes:
comes from lymphoblasts
active in specific immunity
