Answer: Option B) Antigens
Blood typing is based on the presence of proteins known as antigens on the outer surface of the red blood cell plasma membrane.
Explanation:
Blood groups A, B, AB, and O are determined based on the antigen-antibody reactions between donor and recipient bloods.
For instance,
- Blood type A has antigen A on its plasma membrane
- Blood type B has antigen B on its plasma membrane
- Blood type AB has both antigen A and antigen B on its plasma membrane
- while blood type O has neither antigen A nor B on its plasma membrane
So, antigens is the answer
Answer:
I cant read the questions.
Explanation:
In this case, the full medical history of the patient is not endorsed. A patient undergoing treatment of benign prostatic hyperplasia with tamsulosin, an alpha receptor antagonist, will not usually present with deranged clotting mechanisms. From the choices, only warfarin; which actions to antagonize the action of vitamin K thereby significantly reduce vitamin K dependent clotting factors such as factor II, factor VII, factor IX, and factor X. In reducing the levels of vitamin K dependent clotting factors, clotting time; both intrinsic (prothrombin time) and extrinsic (activated thromboplastin time) pathways will be deranged.
