-liquid connective tissue
-primary transports medium
- regulatory device: body temp, pH
- defends body against pathogen invasion
a force that prevents excessive loss of plasma from the capillaries into tissues fluid
called alpha, beta, and gamma
-help transport substances in the blood such as hormones, cholesterol, and iron
small, biconcave disks that lack nucleus when mature
occur in great quantity 4-6 million per mm^3
any method if increasing the normal supply of red blood cells for the purpose of delivering oxygen more efficiently, reducing fatigue, and giving athletes a competitive edge.
condition when there is a an insufficient number of red blood cells or the cells do not have enough hemoglobin
-tired, run down feeling
iron deficiency anemia
the most common form
inadequate amount of iron in the blood which causes insufficient hemoglobin synthesis
sickle cell disease
a hereditary condition in which the individual has sickle shaped red blood cells that tend to rupture as they pass through the narrow capillaries.
hemolytic disease of the newborn
Condition in which antibodies in the mother's blood enter the fetus's blood and cause anemia, jaundice, edema, and enlargement of the liver and spleen. Also called erythroblastosis fetalis., --anemia of a newborn that results from the destruction of the infant's RBCs by antibodies produced by the mother; usually due to an Rh blood type incompatibility
colony- stimulating factor
Protein that stimulates the growth and proliferation of white blood cells (granulocytes).
-granules-lyzozyme, myeloperoxidase, and catalase
Attack general invading pathogens.
do not have cytoplasmic granules and have nonlobular nuclei
include the lymphocytes and monocytes
*THE MOST NUMEROUS OF WBCs
*THEY ARE CONSIDERED THE FIRST LINE OF DEFENSE AGAINIST BACTERIA
*THE INCREASE THE NUMBERS ENGULF AND DEVOUR INVADERS AND ASSIST IN REPAIRING DAMAGED TISSUE
*SOMETIMES THEY DIE DURING THIS PROCESS AND COLLECT WITH BACTERIA TO FORM PUS
*FUNCTION IS PHAGOCYTOSIS
*ADULT PERCENTAGE IS 54% TO 62%
-aka polymorphonuclear leukocytes
u shaped or lobed nucleus
-dark blue color
-release a histamine associates with allergic reactions
accounts fro 25-35% of all white blood cells. 2nd most abundant
- responsible for specific immunity to particular pathogens and toxins
T-directly destroy pathogens
the largest of the white blood cells
- active pagocytes, destroying pathogens m old cells and cellular debris
severe combined immunodeficiency disease
when the stem cells of whit blood cells lack and enzyme called adenosine
the result of fragmentation of large cells called megakaryocytes
-200 billion are created a day
-150,000-300,000 per mm3 of blood
a protein formed by clotting factors from damaged tissue cells and platelets; it converts prothrombin into thrombin, a step essential to forming a blood clot
a bleeding disorder characterized by an abnormal decrease in the number of platelets in the blood, which impairs the clotting process
-a disorder in which the number of platelets is too low due to not enough being made in the bone marrow or the increased breakdown outside the marrow
Blockage of a blood vessel due to a piece of a clot breaking off from another location and preventing blood flow.
excessive bleeding caused by hereditary lack of one of the protein substances necessary for blood clotting
the introduction of blood products into the circulation of a recipient whose blood volume is reduced or deficient in some manner
the clumping together of cells as a result of interaction with specific antibodies called agglutinins
a foreign substance, often a polysaccharide or a protein, that stimulates an immune response
-blood type is named base on the antigens
