A drop of each of the following, is placed separately on four slides. Which of them will not coagulate?
1 Whole blood from pulmonary vein
2 Blood plasma
3 Blood serum
4 Sample from the thoracic duct of lymphatic system
Explanation:
(c) Blood serum does not coagulate because it does not contain any clotting factors. Blood serum is the component that is neither a blood cell (serum does not contain white or red blood cells) nor a clotting factor. It is the blood plasma that includes all proteins not used in blood clotting (coagulation) and all the electrolytes, antibodies, antigens, hormones, and any exogenous substances (e.g., drugs and microorganisms).

Mother-foetus Rh blood type incompatibility disorder can occur if the mother is___and her foetus is____
1 Rh positive;$\text{Rh}$ positive
2 $\text{Rh}$ positive; $\text{Rh}$ negative
3 Rh negative;$Rh$ positive
4 $\text{Rh}$ negative; $\text{Rh}$ negative
Explanation:
(c) In order for the foetus to be Rh positive, the father must also be Rh positive. As a result, when the mother is $\text{Rh}$ negative and the father is $\text{Rh}$ positive (or his $\text{Rh}$ type is unknown), doctors usually assume that there will be a serious medical problem.
