Blood worksheet 2
1.Fill in the blanks
A. The production of RBC is known as Erythropoiesis and is under the control of hormone_erythropoietin _____________________.
B. Write the chain of events which take place during production of RBC based on given diagram:
Letter | Event happening |
A | blood O2 levels decrease |
B | in the kidney |
C | increases the production of erythropoietin |
D | Erythropoietin stimulates red bone marrow to produce more erythrocytes |
E | increased erythrocytes causes an increase in blood O2 levels |
2.During clot formation:
Injury to blood vessel causes, clotting factors get activated.
A.__prothrombinase___acts on prothrombin and it converts prothrombin to thrombin___________.
B. Thrombin acts on fibrinogen_______________to form___fibrin_______________.
Fibrin forms network that traps blood.
3. fill in blanks regarding clot formation control:
A. anticoagulants_________prevent clot formation by two processes.
B. Name the two processes :
heparin and antithrombin
4. Blood grouping:
A. Antigens are molecules present on surface of_erythrocytes__________________.
B. Antibodies are proteins present in__plasma___________________that bind to specific antigens.
C. If antigens on the RBC of blood of donor react with antibodies in the plasma of recipient then the reaction is__hemolytic _________________________.
D. Fill in the table:
Write the type of antigens and antibodies in the blood for each blood group.
one is done for you
Blood group | Antigens on RBCs | Antibodies in plasma |
A | Type A antigen | Anti-B antibodies |
B | type B antigen | anti-A antibodies |
AB | antigens A and B | neither anti-A or anti-B antibodies |
O | neither antigen A nor B | anti-A and anti-B antibodies |
E. O_______________blood group is considered as Universal donors and__AB__________blood group is considered as universal recipients.
F. What happens when person with Type A blood group is given Type B blood?
transfusion reaction
G. What happens when person with Rh–ve blood is given Rh+ve blood?
the first time, your blood produces antibodies against antigens. anytime after that will cause a negative reaction.
H. tell whether the blood from donors is given to recipients in the following conditions:
Donor: person who donates blood
Recipient: person who receives blood
Write whether the donor blood group from the vertical columns can be given to recipients in the horizontal row. Write YES if the blood can be given or NO if blood cannot be given.
One is done for you.
Recipient blood group A | Recipient blood group B | Recipient blood group AB | Recipient blood group O | |
Donor blood group A | Yes | No | Yes | No |
Donor blood group B | no | yes | yes | no |
Donor blood group AB | no | no | yes | no |
Donor blood group O | yes | yes | yes | yes |
