Question

blood types are compatible with each other, but do you know what happens if the wrong type is, and if donated to blood that contains no antigens or an antigen that is different, the blood will attack and destroy the donating blood.
when it comes to type a, type b, type ab and type o blood, there are 2 major antigens.
remember, the antibodies target whichever antigens it identifies as being foreign. antibodies are found in the plasma of the blood.
type a blood contains the “a” antigen, so it has antibodies to destroy type b blood.
type b blood contains the “b” antigen, so it has the antibodies to destroy type a blood.
type ab blood contains both “a” and “b” antigens, so it will not destroy any other blood type.
type o blood will make antibodies for a, b and ab since all the other blood types would be foreign.
if the circles ● represent antigens and the hexagons ● represent antibodies, determine what blood type is in each test - tube.
research and find the answers to the following:
according to the stanford school of medicine, type o - blood makes up:
a. 1.6% b. 6.6% c. 27.6%
the rarest blood type in the us is:
a. a - b. o+ c. ab - d. b+

Explanation:

Step1: Recall blood - type antigen - antibody rules

Type A blood has A antigens and anti - B antibodies.

Step2: Analyze first test tube

It has A antigens and anti - B antibodies, so it's Type A blood.

Step3: Recall blood - type antigen - antibody rules for Type B

Type B blood has B antigens and anti - A antibodies.

Step4: Analyze second test tube

It has B antigens and anti - A antibodies, so it's Type B blood.

Step5: Recall blood - type antigen - antibody rules for Type AB

Type AB blood has both A and B antigens and no anti - A or anti - B antibodies.

Step6: Analyze third test tube

It has both A and B antigens and no anti - A or anti - B antibodies, so it's Type AB blood.

Step7: Recall blood - type antigen - antibody rules for Type O

Type O blood has no A or B antigens and has both anti - A and anti - B antibodies.

Step8: Analyze fourth test tube

It has no A or B antigens and has both anti - A and anti - B antibodies, so it's Type O blood.

Answer:

The first test tube is Type A, the second test tube is Type B, the third test tube is Type AB, the fourth test tube is Type O.
