Human bio chapter 6

transportation, defense, and regulation

produced in red bone marrow, red blood cells white blood cells platelets

91% water and 9% salts, solutes help maintain osmotic pressure (salts act as a buffer)

Albumins, Globulins, and Fibrinogen

help from blood leaking from vessel

help fight infections, and transports molecules in blood

its inactive, but when activated it forms blood clots

RBCs are specialized for oxygen transport, they contain protein (hemoglobin) and will bind to oxygen and iron groups

no nucleus, shape allows them to squeeze through small capillaries and maximize surface area

(leukocytes) fight infections

Neutrophil, Esoihophil, Basophil

Lymphocyte, monocyte

leukemia- a group of cancers that affect blood and bone marrow

Comes from Myeloblasts contains granules phagocytizes pathogens

comes from lymphoblasts active in specific immunity

comes from monoblasts becomes a large phagocyte

comes from myeloblasts contains granules active in allergies and worm infections

comes from myeloblasts contains granules releases histamine

leukemia begins in bone marrow, where while blood cells are produced. and impacts body’s immune response and overall health

preventing absurd blood loss, response to injury, systemic regulation,

1) blood vessel is punctured 2) platelets congregate and form plug 3) platelets and damaged tissue cells release prothrombin activator, which initiates a cascade of enzyme reactions 4) Fibrin threads form and trap RBCs

Thrombocytopenia- too few platelets Thromboembolism- when thrombus (stationary clot), forms, travels (embolism) and plugs other vessel Hemophilia A and B- genetic deficiencies of a clotting factor

platelets, clotting factors, Fibrinogen

stages of blood clotting work in concert to prevent excessive bleeding and facilitate healing.
