blood introduction
Blood - Introduction
  • Blood – a type of connective tissue that consists of cells and cell fragments surrounded by a liquid matrix.
  • The liquid portion is the plasma.
  • Total blood volume for avg. adult female = 4 to 5 liters and avg. adult male = 5 to 6 L
  • Blood makes up about 8% of total body weight
functions of blood
Functions of Blood
  • Transports oxygen, nutrients, enzymes, and hormones
  • Transports CO2 and waste products away from tissue
  • Maintains body temperature
  • Maintains body fluids
blood facts
Oxygen enters blood in the lungs and CO2 enters blood from tissues.

95% of the volume of blood consist of RBC or erythrocytes

5% consists of WBC or leukocytes and cell fragments called platelets or thrombocytes

Blood Facts
blood grouping
Blood Grouping
  • Blood groups are determined by antigens on the surface of RBC.
  • Antigens are molecules
  • Antibodies will bind to the antigens resulting in agglutination or hemolysis or RBC.
  • Agglutination – clumping of RBC
  • Hemolysis – rupture of RBC
abo blood group
ABO Blood Group
  • Blood is categorized by the ABO Blood group system
  • ABO antigens appear on the surface of RBC
blood types
Blood Types
  • Type A Blood – A antigen
  • Type B Blood – B antigen
  • Type AB Blood – A and B antigen
  • Type O Blood – does not have A or B
population distribution
Population Distribution
  • Type A – 41%
  • Type B – 10%
  • Type AB – 4%
  • Type O – 45%
  • Rh+ - 85%
  • Rh- - 15%
blood types1
Blood Types
  • Type A Blood – B antibodies
  • Type B Blood – A antibodies
  • Type AB Blood – does not have A or B
  • Type O Blood – has A and B
  • Mismatching Blood groups can result in transfusion reaction.

rh blood group
Rh Blood Group
  • Another blood group that was first studied in the Rhesus monkey.
  • Rh+ - Rh antigens on RBC
  • Rh- - Rh antigens are not present
  • Can cause a problem in pregnancy if mother is Rh- and baby is Rh+
  • Mother will make antibodies against the baby
  • Prevention – mother gets shot of Rho immune globulin
erythrocytes
Erythrocytes
  • Disc shaped
  • Live ~ 120 days in males and 110 days in females
  • Transport oxygen and remove CO2
  • Contain hemoglobin – pigment – red color
erythrocytes1
Erythrocytes
  • Hemoglobin bound to oxygen is bright red in color
  • Hemoglobin that is without oxygen is darker red
  • ~2/3 of body’s iron is found in hemoglobin
  • No nucleus
history of rbc
~2.5 million RBC are destroyed every second

New RBC are produced as quickly as they are destroyed

Hematopoiesis – process of blood cell production

Low blood oxygen level will cause RBC production

Blood cells are formed in red marrow in bones

Jaundice – a build up of bilirubin in circulation causing a yellow skin color

History of RBC
types of bone marrow
Types of Bone Marrow
  • Red Marrow – found in spongy bone and forms WBC, RBC, and platelets
  • Yellow Marrow – composed of fat and is not capable of blood cell formation
  • After age 20, blood formation occurs in humerus, femur, cranium, ribs, sternum, clavicles, vertebrae
leukocytes
Leukocytes
  • White blood cells
  • Spherical shape
  • Whitish color because they lack hemoglobin
  • Large than RBC
  • Have a nucleus
  • Protects against microorganisms
  • If person’s WBC count is high - infection
3 kinds of granulocytes
Neutrophils – most common type

Remains is blood ~

10 – 12 hours

Dead cell debris forms pus at site of infection

Eosinophils – release chemicals that reduce inflammation

Basophils – help regulate inflammatory response

Release histamine = promotes inflammation

Release heparin – prevents clots

3 Kinds of Granulocytes
2 types of agranulocytes
Lymphocytes – smallest

Plays important role in body’s immune system

Produces antibodies

Monocytes – largest

After they leave the blood and into the tissue – they become macrophages

Macrophages – destroy bacteria, dead cells, and other debris

2 Types of Agranulocytes
platelets
Platelets
  • Thrombocytes – minute fragments of cells
  • Produced in red marrow
  • Prevent blood loss by causing blood clotting
preventing blood loss
Blood vessels constrict in response to injury, resulting in decreased blood flow.

A platelet plug is produced to seal off the wound

Serotonin is released to cause the blood vessels to constrict.

Blood clot – thrombus

Embolus – detached clot

A heart attack can occur from blockage of blood vessels that supply blood to heart

Streptokinase and aspirin can be given to break down the clot

Preventing Blood Loss
transfusions
Transfusions
  • Transfusion – transfer of blood
  • Donor – person who gives blood
  • Recipient – person who receives blood
  • Universal Donor – Type O Blood
  • Universal Recipient – Type AB Blood
complete blood count
Complete Blood Count
  • CBC – complete blood count
  • Analysis of RBC, hemoglobin, and WBC
  • RBC – male – 4.6 to 6.2 million/mm3
  • Female – 4.2 to 5.4 million/mm3
  • WBC – 5000 – 9000/mm3
hemoglobin measurement
Hemoglobin Measurement
  • Determined amount of hemoglobin in a given volume of blood
  • Male – 14 to 18 grams/100mL
  • Female – 12 to 16 grams/100mL
  • Low hemoglobin – anemia – low RBC
