Multiple choice biology transportation in plants and animals blood transfusion transfusion of blood blood and organ donation

Erythroblastosis foetalis occurs when a factor from mother passes into foetus through placenta _________________.

  1. Rh antigens

  2. Agglutinins

  3. Rh antibodies

  4. ABO antibodies.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Erythroblastosis foetalis occurs when an Rh-negative mother develops Rh antibodies against the blood of an Rh-positive fetus, which then cross the placenta and destroy fetal red blood cells.

Like sickle cell anemia, which is the other generic disorder related to blood pigment?

  1. Phenylketoneunia

  2. Leukemia

  3. Thalassemia

  4. Xeroderma pigmentosis
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Thalassemia is a human anaemia due to an autosomal mutant gene and when this change is present in the homozygous condition, the trait is severe thalassemia major and causes death in childhood.
The heterozygous individuals show a mild disease also known as thalassemia minor.
The person suffering from thalassemia major are unable to produce a beta chain. Their haemoglobin contains delta change like that of the foetus and it is unable to carry oxygen transport.
So, the correct option is 'thalassemia.'

The disease erythroblastosis foetalis of human baby is due to

  1. Incompatibility of blood groups of the couple

  2. Incompatibility of blood groups of embryo and mother

  3. Maladjustment of Rh factor

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The disease erythroblastosis fetalis of human baby occurs due to incompatibility or maladjustment of Rh factor. It occurs when a Rh+ father and Rh-- conceive a baby. During the time of delivery, some of the blood cells from baby enter the mother's blood stream. The immune system of mother will the recognize the cells as foreign particles and produces antibodies against them. In the subsequent pregnancy with Rh+ baby, there are chances of Rh disease. The blood circulation of mother and baby is separated but still the antibodies of mother's body can cross the placenta and enter the blood stream of baby. The antibodies cause breakdown of RBCs of the baby leading to anaemia and ultimately death. So the problem does not arises at the time of birth of first child but in subsequent pregnancy, there is risk of erythroblastosis fetalis. 
So, the correct answer is 'Maladjustment of Rh factor'.

D Correct answer
Explanation

Donors and recipients in a blood transfusion process can be : father and son, brother and sister and maternal uncle and niece. This kind of blood transfusions are maximum compatible.

Donors and recipients of blood transfusion can be

  1. Only father and son

  2. Only brother and sister

  3. Only maternal uncle and niece

  4. All the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In the blood transfusion process, transfer of blood is possible between son and father, brother and sister, maternal uncle and niece.

So, the correct option is ‘All the above’.

Multiple choice biology transportation in plants and animals blood transfusion transfusion of blood blood and organ donation

Which blood group an safely be transfused in emergency when there is no time to analyse the blood group of recipient?

  1. O and $Rh^-$

  2. O and $Rh^+$

  3. B and $Rh^-$

  4. AB and $Rh^+$.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Individuals with type O blood do not produce ABO antigens.  Therefore, their blood normally will not be rejected when it is given to others with different ABO types.  As a result, type O people are universal donors for transfusions, but they can receive only type O blood themselves.

So, the correct option is O and Rh-.'.

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$^{-}$'.

Multiple choice biology transportation in plants and animals blood transfusion transfusion of blood blood and organ donation

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.
Reveal answer Fill a bubble to check yourself
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.
