17-Graveyard in RBCs is Spleen
18-During diastole Blood enters the heart.
19-Globulins contained in human blood plasma are primarily involved in defense mechanisms of the body.
20-The most popularly known blood grouping is the ABO grouping. It is named ABO and not ABC because ‘O’ in it refers to having no antigens A and B on RBCs.
