Physical Characteristics of Blood

 Color selection Oxygen-rich bloodstream is scarlet red Oxygen-poor blood is dull crimson   pH must remain between 7. 35–7. 45  Blood temp is a little bit higher than body's temperature Copyright © 2003 Pearson Education, Inc. publishing while Benjamin Cummings

Blood Plasma

 Composed of approximately 90 percent water  Includes various dissolved chemicals  Nutrients  Debris (metal ions)  Respiratory system gases  Hormones  Proteins  Waste products Copyright © 2003 Pearson Education, Inc. submitting as Dernier-ne Cummings

Plasma Healthy proteins

 ?ggehvidestof – regulates osmotic pressure  Coagulation proteins – help to come blood loss each time a blood boat is hurt  Antibodies – support protect your body from antigens

Erythrocytes (Red Blood vessels Cells)

 The main function is to bring oxygen  Anatomy of circulating erythrocytes  Biconcave disks  Essentially carriers of hemoglobin  Anucleate (no nucleus)  Include very few organelles

 Outnumber white blood vessels cells a thousand: 1

Hemoglobin

 Iron-containing healthy proteins  Binds strongly, nevertheless reversibly, to oxygen  Each hemoglobin molecule provides four fresh air binding sites  Every single erythrocyte offers 250 million hemoglobin substances Slide 12. 11

Leukocytes (White Bloodstream Cells)

 Crucial inside the body's defense against disease  These are complete cells, with a nucleus and organelles  Capable to move into and out of blood vessels (diapedesis)  Can easily move simply by ameboid movement  May respond to chemical compounds released simply by damaged cells Copyright © 2003 Pearson Education, Incorporation. publishing since Benjamin Cummings

Leukocyte Levels in the Blood

 Normal amounts are among 4, 1000 and 14, 000 cellular material per millimeter  Unnatural leukocyte amounts  Leukocytosis  Over 11, 1000 leukocytes/ml  Generally implies an infection  Leukopenia  Abnormally low leukocyte level  Typically caused by selected drugs Copyright © the year 2003 Pearson Education, Inc. creating as Dernier-ne Cummings

Types of Leukocytes

 Granulocytes

 Granules in their cytoplasm could be stained  Include neutrophils, eosinophils, and basophils Determine 10. some

Granulocytes

 Neutrophils

 Multilobed center with fine granules  Act as phagocytes at energetic sites of infection

 Eosinophils

 Large brick-red cytoplasmic granules  Seen in repsonse to allergies and parasitic worms Copyright © 2003 Pearson Education, Inc. publishing since Benjamin Cummings...
