Definition
  • Age
  • Body type
  • Sex
  • Method of measurement
Term

What are critical components of coagulation?

 

AKA blood clotting

Definition
  • Prothrombin
  • Thrombin
  • Fibrinogen
  • Fibrin
Term

What are the formed elements of the blood?

Definition
  • RBC's
  • WBC's
  • Platelets
Term

What type of drug is heparin?

Definition

Anti-Coagulant: to prevent blood clots

 

(blood thinner)

Term

What are the parts of leukocytes?

Definition
  • Granulocytes (Neutrophils, Eosinophils)

Agranulocytes (Lymphocytes, Monocytes)

Term

What is the largest type of leukocyte?

Definition
Monocytes-mobile and highly phagocytic cell.
Term

Describe red blood cells.

Definition
  • No Nucleus and shaped like tiny biconcave disk
  • Do not contain ribosomes, mitochondria, or other organelles typical of most body cells
  • primary component is hemoglobin
  • most numerous of the formed elements
Term

What are the functions of platelets?

Definition
  • Primary role is Hemostasis and blood coagulation
  • Secondary role in defending against bacterial attacks.
Term

Understand the four blood groups (A, B, AB, and O).

Definition
  • A-antigen A
  • B-antigen B
  • AB-both antigens
  • O-neither antigen
Term

What is the lifespan of a circulating erythrocyte?

Definition
105-120 days
Term

What do globulins do?

Definition
Essential component of the immunity mechanism.
Term

Know what makes up blood plasma.

Definition
90% Water, 10% solutes
Term

What percent of whole blood constitutes what percent of body weight?

Definition
  • 8% of total body weight
  • Of that: plasma-55% and formed elements-45%
Term
Understand the process of clot formation
Definition

3 stages:

  1. Production of thromblastin activator 
  2. Conversion of prothrombin to thrombin
  3. Conversion of fibrinogen to fibrin and production of fibrin clot.
Term

What does heparin do?

Definition
Prevents blood clots-blood thinner.
Term

Definition
A decrease in # of volume of functional RBC's
Term

Embolism

Definition
Condition that results from a moving blood clot circulation in the bloodstream.
Term

Leukemia

Definition
Term used to describe a # of blood cancers affecting WBC's
Term

Neutrophils

Definition
Most circulating of WBC's-65%-highly mobile and active phagocytic cells.
Term

Albumins

Definition
Help maintain osmotic balance of the blood.
Term

Definition
Largest leukocyte, mobile and highly phagocytic cells
Term

Hemostasis

Definition
Stoppage of blood
Term
Thrombocytes 
Definition
Platelets, small pale bodies that appear as irregular spindles or oval disks
