Cards

Term
Blood
Definition
Connective tissue containg cells plus liquid matrix; 50:50 ratio
Term

Cells of Blood

(formed elements)

Definition

Red Blod Cell (erythrocyte) 

White Blood Cell (leukocyte) 

Platelet 

Plasma (liquid matrix)

Term
Funtion of Blood
Definition

1. Transport - everything 

2. Maintenance and Regulation - body temperature, osmotic pressure, and pH (bicarbonate buffers) 

3. Protection - against blood loss (hemostasis), against infection (antibodies/phagocytosis)

Term
Blood Volume
Definition

Adult male = 5 - 6 L 

Adult female = 4 - 5 L 

(lose up to 30% and live)

**4L lose about 1L and 6L lose about 2L**

Term
Hematocrit
Definition

The % of RBCs by the volume in whole blood

 Males: 42-52%

Females: 37-47% 

**Testoserone simulates the red blood cell formation**

Term
Hemoglobin Concentration
Definition

Hematocrit(as a decimal) x 34 = Hemoglobin

.43x34=14.6 

Males: 14 - 18g/dL

Females: 12 - 16g/dL

 

Term
Plasma
Definition

90% Water

8% Proteins (most made in the liver)

**No hemoglobin in plasma**

**Plasma=serum**

 Plasma Protiens

1. Albumins "do nothing" = help maintain osmotic pressure & act as buffers

2. Globulins = transport globulins"carry things" & gamma globulins"antibodies"

3. Clotting Proteins

4. Misc Proteins

 

 

Term
Hematopoiesis
Definition

"making blood"

 Formation of blood cell components

Term
Neutrophil
Definition

Normal Range: 40%-70%

"most common WBC"

Function: phagocytosis/upon death they release cytotoxic chem and kill surrounding cells "suicide bombers"

Life Span: few hours to a day

Appearance: [image]

nucleus = segmented "linked sausages"

size = 2x diameter of RBC

cytoplasm = granulated

Term
White Blood Cells
Definition

Leukocytes - protect against infection, clean up damage tissues, and plug leaks

Granulocytes = neutrophils, eosinophils, basophils

Agranulocytes = monocytes, lymphocytes

Term
Basophil
Definition

Normal Range: >0.2%

Function: release histimine and heprin to initiate inflamation

Appearance: [image]

 

 

Term
Eosinophils
Definition

Normal Range: 1% - 4%

Function: attack parasitic worms (secrete cytotoxic chem); decrease allergic response (antihistamine)

Life Span: a few days

Appearance: [image]

nucleus = two lobed shape "telephone reciever"

size = 2x RBC

cytoplasm = granules will stain bright red orange
