A person with blood group ${B^ + }$ met with an accident and losses a lot of blood.Which pair of individuals can denote blood to him?

  1. $A{B^ + },{B^ + }$
  2. $A{B^ - },{B^ - }$
  3. ${A^ + },{B^ - }$
  4. ${O^ + },{B^ - }$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

B$^{+}$ blood group contain antibody-A and type B antigen. A person with blood group B$^{+}$ can receive blood from B$^{-}$ as due to the presence of same type of antigen in them, there won't be any transfusion reactions. While O$^{+}$ blood group does not contain any type of antibody. 

So, the correct option is 'O$^{+}$, B$^{-}$'.

Which one of the following statements is correct with regard to the principle of safe blood transfusion?

  1. The recipient's serum should not contain antigens against the donor's antibodies.

  2. The donor's red blood corpuscles should not contain antibodies against the recipient's serum.

  3. The recipient's red blood corpuscles should not contain antibodies against the donor's antigen.

  4. The recipient's serum should not contain the antibodies against the red blood corpuscles of the donor.

D Correct answer
Explanation

Blood transfusion is generally the process of receiving blood into one's circulation intravenously. Antigens are present on the surface of red blood corpuscles, while antibodies are present in the plasma of the blood, for e.g., people with blood group A have surface antigen A on their RBC's and antibodies to antigen B in their plasma. So, when RBC's are donated, transfer of antibodies doesn't take place. But as the RBC's of the donor have a surface antigen, it should be ensured that recipient's serum should not contain antibodies against the antigen on red blood corpuscles of the donor. Otherwise, if transfusion is made between incompatible donor and recipient, the reaction between antigens on the RBC (from the donor) and antibodies in the plasma (of the recipient) will produce clots and clog capillaries. Thus, the correct answer is option D.

RH factor is a term that you will hear in connection with

  1. Blood transfusion

  2. Air pressure

  3. Space travel

  4. Star war
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Rhesus (Rh) factor is a protein found on the surface of red blood cells. If blood lacks the protein called as Rh negative and if present, called as Rh positive . Rh positive is the most common blood type. Having a Rh negative blood type is not an illness and usually, does not affect health. It should be tested before blood transfusion because it can harm the blood cell and other organs due incompatibility of blood. Thus, option A is correct.

Xenograft is a graft

  1. Between genetically identical individuals.

  2. Between individuals of different species.

  3. From one individual to another of same species.

  4. From one area to another of same individual.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • In Xenotransplantation, Xenos means foreign or strange.
  •  It is also called a Heterologous transplant.
  •  In xenotransplantation, the transplantation of living cells, tissues or organs from one species to another.
  •  Such cells, tissues or organs are called xenografts or xenotransplants. Hence, Xenograft is a graft Between individuals of different species. 
So, the correct answer is 'Between individuals of different species'.

There are minimum chances of a body rejecting a transplanted organ if the donor is a

  1. Sibling

  2. Spouse

  3. Offspring

  4. Twin
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The maximum similarity in physiology is between twins as they arose from the same conditions and cell arrangement within the womb of the mother.

Hence, there is a minimum chance for rejecting transplanted organs due to similar immune development.
So, the correct option is 'twin'.

Tissue grafting or organ transplant in between the genetically dissimilar individuals of the same species is called

  1. Allogarft

  2. Xenograft

  3. Isograft

  4. Autograft
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • Transplantation of cells, tissue grafting or organ transplant in between the genetically nonidentical individuals of the same species is called as allotransplant or Allograft.  
  • A graft is the transplantation of an organ or tissue to a different location, with the goal of replacing a missing or damaged organ or tissue. 
  • Grafts are typically moved without their attachments to the circulatory system and must reestablish these, in addition to the other connections and interactions with their new surrounding tissues. 

So, the correct answer is "Allograft".

During injury mast cells secrete 

  1. Histamine

  2. Heparin

  3. Prothrombin

  4. Antibodies
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

the mast cells of injured tissue secrete histamine, which causes the surrounding blood vessels to dilate and increase the permeability. It gives local immune response and act as neurotransmitter.
Thus, the correct answer is option A.

Allogeneic transplants require immunosuppressant drugs because these are transplants between

  1. Genetically different members of the same species.

  2. Genetically different members of different species.

  3. Genetically similar members of the same species.

  4. Genetically similar members of the different species.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A- Allogenic transplant takes place between genetically different members of same species. Immunosuppressant drugs are used to suppress graft-versus-host disease (GVHD) which is the result of an intricate immune response following allogeneic stimuli due to allogenic transplant.
