Answer 6

Richard Lower

Question 7

Performed the first human-to-human transfusion in 1795 but this was not documented.

Answer 7

Philip Syng Physick

Question 8

Subsequently performed and published a set of animal experiments which proved that the donor and the recipient must be of the same species.

Answer 8

John Henry Leacock

Question 9

In 1825, He successfully transfused a woman dying from postpartum hemorrhage with by transfusing blood from the woman’s husband.

Answer 9

James Blundell

Question 10

Observed red cell lysis in the blood of a woman who died after receiving a transfusion of sheep blood. He also observed that incompatible transfusion reactions were associated with hemorrhage and congestion of the kidneys, lungs, and liver.

Answer 10

Emil Ponflick

Question 11

Observed that human red cells would lyse when mixed with the sera of other animals. He set the stage for the study of the immunologic basis of blood incompatibility.

Answer 11

Leonard Landois

Question 12

Recommended the use of an anticoagulant.

Answer 12

Braxton Hicks

Question 13

Discovered the ABO blood group and explained the serious reactions that occur in humans as a result of incompatible transfusions in 1901.

Answer 13

Karl Landsteiner

Question 14

The clumping of cells.

Answer 14

Agglutination

Question 15

Discovered the fourth less frequent blood group “AB”.

Answer 15

Alfred von Descatello and Adriano Sturli

Question 16

Discovered the Rh blood group.

Answer 16

Karl Landsteiner and Alex Weiner

Question 17

The units of heredity; Often defined at the molecular level as a DNA sequence and are responsible for expression of a trait.

Answer 17

Genes

Question 18

One of two or more alternate forms of a gene.

Answer 18

Allele

Question 19

The set of genes possessed by an individual organism.

Answer 19

Genotype

Question 20

A physical trait whose expression depends on the inherited genes along with environmental factors.

Answer 20

Phenotype

Question 21

The phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.

Answer 21

Dominant

Question 22

A trait resulting from an allele that is independently and equally expressed along with the other.

Answer 22

Codominant

Question 23

A trait that is expressed only when genotype is homozygous; a trait that tends to be masked by other inherited traits, yet persists in a population among heterozygous genotypes.

Answer 23

Recessive

Question 24

Testing the compatibility of the donor blood and the recipient blood.

Answer 24

Crossmatching

Question 25

This detects if the recipient has antibodies which can destroy the transfused red blood cells from the donor.

Answer 25

Major Crossmatch: RSDC (Recipient Serum + Donor Cells)

Question 26

This detects if there are antibodies in the donor’s serum that can destroy the patient’s red blood cells.

Answer 26

Minor Crossmatch: DSRC (Donor Serum + Recipient Cell)

Answer 27

KAYANG KAYA!
