6.2 The Blood Flashcards
is composed of liquid, the plasma, and of formed elements, the blood cells
The blood
is the liquid part of the blood, colorless fluid. 90% of it is water
Blood Plasma
o Water
o Inorganic salts
-Sodium, phosphates, potassium, bicarbonates, calcium, iodine, magnesium, iron, chlorides, copper
Blood Plasma
o Albumin
o Fibrinogen
o Globulins – antibodies
Blood proteins
o Amino acids from proteins
o Glucose from carbohydrates
o Sugars and starches
o Fatty acids, glycerine from lipids (fats)
Digested food products
o Pituitary gland o Thyroid gland o Parathyroid gland o Pancreas o Suprarenal glands o Gonads
Hormones from the endocrine glands
White blood cell, leukocytes
- Granulocytes
- Agranulocytes or nongranulocytes
Granulocytes
- Neutrophils (polymorphonuclear)
- Eosinophils
- Basophils
Agranulocytes or nongranulocytes
- Lymphocytes
- Monocytes
Cytos, kytos
a cell
Erythros
red
Leukos, leuco
white
Corpus
body
Corpuscle, corpusculus
little body
Produced by the bone marrow, liver, spleen, lymph nodes, and thymus gland
Blood cells
Red blood cells or corpuscles
erythrocytes
Disc shaped cells, concave on both surfaces when viewed on edge
Red blood cells or corpuscles – erythrocytes
They are formed in the bone marrow
Red blood cells or corpuscles – erythrocytes
Red blood cells or corpuscles – erythrocytes: __ microns in diameter
7
Red blood cells or corpuscles – erythrocytes: _____ rbc per cubic mm of blood
4,500,000 to 6 million
a compound of iron and a protein and forms in red blood cells during their development
Hemoglobin
transports oxygen from the lungs to all body tissues and cells. They also transport some carbon dioxide from body tissues to the lungs for elimination
Red blood cells or corpuscles – erythrocytes
Leukocytes or leucocytes
White blood cells
White blood cells – Leukocytes or leucocytes ____ cells per cubic mm of blood
6,000 to 10,000
have granules in the cytoplasm
Granulocytes
60% to 70% of the leukocytes. Fine granules. Stain lilac, not red or blue. Cell nucleus has from 2 to 5 lobes joined together by narrow strands. Polymorphonuclear
Neutrophils
medium sized granules. Stain red with an acid dye such as eosin. 2% to 3% of all leukocytes
Eosinophils
coarse granules. 1% of the leukocytes. Stain blue with a basic dye such as methylene blue
Basophils
nongranulocytes
Agranulocytes
single large nucleus and stains reddish blue. 25% of all leukocytes
Lymphocyte
Have a single rounded or kidney shaped nucleus that stains reddish purple
Monocytes – (mononuclear)
defend the body from bacterial infections
Leukocytes
help repair damaged tissue by a process of phagocytosis
Leukocytes
They also aid in the clotting of blood
Leukocytes
are increased in number in asthma and some parasitic diseases
Eosinophils
are responsible for the development of immunity, the production of antibodies, gamma globulin, etc.
Lymphocytes
Small irregular fragments of cells that are formed in the bone marrow
Blood platelets or Thrombocytes
Concerned with the blood clotting
Blood platelets or Thrombocytes
200,000 to 400,000 per cubic mm of blood and appear as minute stained particles in blood smears
Blood platelets or Thrombocytes
a blood protein, formed in the liver, circulates in solution in blood plasma
Fibrinogen
is an enzyme formed in the liver, and circulated in solution in the blood plasma
Prothrombin
ingested with food also circulates in the blood plasma in an ionized state
Calcium
does not circulate in the plasma but is present in tissue cells
Thromboplastin or thrombokinase
is present in the liver and some other organs and dissolved in plasma. It acts to prevent blood from clotting within the blood vessels
Heparin or antithrombin
Following an injury, the injured tissue cells liberate thromboplastin at the site of injury. _____ may also give similar substance
Platelets
thus freed comes into contact with the spilled blood and converts the prothrombin dissolved in it to thrombin
Thromboplastin
form fibrin
Thrombin + calcium + fibrinogen
consists of fine threads precipitated from the dissolved fibrinogen
Fibrin
Water for body tissues and cells, to provide a solvent in which digested food products, blood proteins, minerals, gases, vitamins, hormones, and waste products are dissolved, for transportation
Blood plasma
A medium in which blood cells circulate throughout the body
Blood plasma
Contain hemoglobin for transportation of oxygen, and some carbon dioxide
Red blood cells
Is an iron protein compound in RBC that unites readily with oxygen forming oxyhemoglobin for transportation of oxygen to body tissues
Hemoglobin
Circulating in plasma, destroy microorganisms resulting from infection, and help to form blood clots
Leukocytes
function in immunization
Lymphocytes
Function in blood clotting, liberate thromboplastin or similar substances, and clump to plug ruptures
Blood platelets
to arrest hemorrhage by plugging blood vessels
Coagulation of blood
an increase in number of leukocytes in the circulating blood
Leucocytosis or leukocytosis
a decreased in the number of leucocytes in the circulating blood
Leucopenia
an absence or marked decrease in the number of leucocytes in circulating blood
Agranulocytosis
a decrease in the number of red blood cells in circulating blood
Anemia
a decrease in the hemoglobin content of each red blood cell – an iron deficiency
Anemia
an increase in the number of the red blood cells in circulating blood
Polycythemia
the absence of gammaglobulin, containing antibodies
Agammaglobinemia
