BN507 - MODULE 13 - BLOOD EXAM QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS VERIFIED
Outline the overall functions of blood
Transportation, Regulation & Prevention
What is blood transporting?
Nutrients, Respiratory gases, waste products, hormones and various proteins
What is blood regulating?
Body temperature, fluid volume, pH Balance
What is blood preventing?
blood loss, infection
Outline constituents of plasma?
Plasma proteins, nutrients, electrolytes, respiratory gases and hormones
What are the formed elements in blood?
RBCs (erythrocytes)
WBCs (leukocytes)
Platelets (thrombocytes)
Outline the process of haematopoiesis?
All body cells form from one stem cell and then are formed into different type of blood
cells. RBC's are formed in red bone marrow continuously
Describe general structure and function of RBC's (erythrocytes)
Biconcave, no nucleus, contains Haemoglobin, lacks organelles, transports 02 and CO2
, Outline the lifecycle of erythrocytes
Live for 120 days when they are worn out, they split into the heme and globin portions.
2. globin is broken down into amino acids, which is reused to synthesise new proteins
3. Iron removed from heme and stored in liver or bound to transferrin
4. The remainder of Heme is degraded into bilirubin which goes through the metabolic
process via the liver /small intestine/kidney for elimination
What are the 6 types of WBC's (Leukocytes)
Neutrophil
Basophil
Eisanophil
Monocyte
B Lymphocyte
T Lymphocyte
What does a Neutrophil do?
Digests and destroys some bacteria, fungi & viruses
What does a Eisonophil do?
Attacks parasitic worms and involved in allergic and asthmatic reactions
What does basophil do?
Stimulates vasodilation and attracts other WBC's to areas of infection and inflammation
What do monocytes do?
Phagocytise infectious microbes, foreign antigens, cellular debris and dead and
disfunction cells
What do B Lymphocytes do?
