Chapter 6: Blood & The Lymphatic & Immune Systems Flashcards
Platelets
Initiates blood clotting process
What are the formed elements of blood cells?
Erythrocytes
Platelets
Leukocytes
Plasma
The average adults has how much blood?
5 liters
Hematopoiesis
The process in which blood cells are produces in red bone marrow
What are the proteins in plasma?
Albumin
Globulin
Fibrinogen
Albumin
Helps transport fatty substances
Globulin
Gamma globulins are antibodies
Fibrinogen
Blood clotting Protein
What are red blood cells?
Enucleated erythrocytes
What gives red blood cells their color?
Hemoglobin
What is the lifespan of a red blood cell?
120 days
What are White blood cells?
Leukocytes that provide protection against pathogens.
What are the 2 categories for white blood cells?
Granulocytes
Agranulocytes
Granulocytes
Have granules in cytoplasm
Agranulocytes
No granules in cytoplasm
What are the 3 types of granulocytes?
Basophils
Eosinophils
Neutrophils
Basophils
Release histamine & heparin to damaged tissue
Eosinophils
Destroy parasites & increase during allergic reaction
Neutrophils
Important for phagocytosis
What are the 2 types of Agranulocytes?
Monocytes
Lymphocytes
Monocytes
Important for phagocytosis
Lymphocytes
Provide protection through immunity
What are platelets?
Also known as thrombocytes, they are critical in clotting. They lead to the formation of thrombin.
Agglutinate
Clots that form into small clusters when blood vessel is damaged.
Thrombin
Converts fibrinogen to fibrin.
Type A Blood
Produces anti-B antibodies that attack type B & AB blood.
Type B Blood
Produces anti-A antibodies that attacks type A & AB blood.
Type O Blood
Produces anti-A & anti-B antibodies that attacks type A, type B, & type AB blood.
Type AB Blood
Produces no antibodies that does not attack any other type of blood.
Universal Donor
A type O blood that does not have an antibody, so it will not attack any blood type.
Universal Recipient
A type AB blood that has no antibodies against other blood types and therefore, receive any type of blood.
Rh+
Will not make anti-Rh antibodies
Rh-
Will produce anti-Rh antibodies
agranulocyte
white blood cell without granules
sanguinous
pertaining to blood
thrombocytosis
condition of having too many platelets
thronbopenia
condition of having too few platelets
Hemoglobin
Blood protein
What are the 5 organs of the lymphatic System?
Lymph nodes Lymphatic vessels Thymus gland Spleen Tonsils
Lymph
fluid within lymphatic vessels
Lacteals
lymph vessels around the small intestine that assists with fat absorption
Lymphatic Vessels
One-way pipe conducting lymph from tissues toward thoracic activity using valves to prevent backflow
What is the progress of lymphatic vessels?
Lymph capillaries in tissues merge into larger lymph vessels that drain into one of two large lymphatic ducts in thoracic activity
Lymph Nodes
Removes pathogens & cell debris from lymph as it passes through
Traps and destroys cells from cancerous tumors
Tonsils
Collections of lymphatic tissue located on each side of throat
What are the 3 sets of tonsils?
Palatine
Pharyngeal
Lingual
Spleen
Consists of lymphatic tissue that is highly infiltrated with blood vessels
What is the function of a spleen?
Phagocytic macrophages line blood sinuses to remove pathogens
Filters out and destroys old red blood cells, recycling iron
Thymus Gland
Secretes hormone
Changes lymphocytes to T Lymphocytes (T Cells)
Whaat are the 2 forms of immunity?
Natural
Acquired
Natural Immunity
Doesn’t require prior exposure to pathogen
Acquired Immunity
Body’s response to a specific pathogen
May be either Passive or Active
Passive Acquired Immunity
When a person receives protective substances produced by another human or animal
Active Acquired Immunity
Develops following direct exposure to pathogen
Stimulates immune response
Immune Response
Antigens stimulate immune response
What are the 2 different processes of Immune Response
Humoral immunity
Cellular Immunity
Humeral Immunity
Production of B lymphocytes
Cellular Immunity
Produces T Cells and Natural Killer Cells
Nosocomial Infection
Acquired in the hospital
Cross Infection
Pathogen acquired from another person
Reinfection
Becomes infected again with same pathogen
Self-Inoculation
Pathogen from one part of the patient’s body spreads to another part of the body
axillary
pertaining to the underarm region
immunoglobulins
antibodies secreted by B cells; assist in protecting the body
inguinal
pertaining to the groin region
lymphangial
pertaining to the lymph vessels
urticaria
severe itching associated with hives
White Blood Cells
Fight infection & disease
