Answer 1

Que-14:- haematopoiesis takes place in bone marrow in faetus and in adult it takes in spleen ,thymus etc. QUE-16:- you can have any type of blood group A,B,AB,O. QUE-17:- when blood clumps in the still liquid plasma it is called agglutination.it is the process when red blood cell collect into a clump and which occurs as response to a specific antibody. QUE-18:- Thrombocytes more commonly known as platelets. QUE-19:- Mother-fetus Rh blood type incompatibility occurs when mother have Rh(-)ve and her fetus have Rh(+)ve blood group. due to this mother blood can cross the placenta and destroy fetal antibody and it fatal condition develops as per successive pregnancies.as mother blood forms antibody against Rh(+)ve blood which is different from mother's blood type. QUE-20:- An increased in WBC count is indicative to Leukemia disease. this disease occurs when the DNA of immature blood cells mainly white cell damaged this causes blood cell to grow and divide continuously and hence cell count increases rapidly. QUE-21:- white blood cells basically defend against infection .when any infection occurs then leukocyte(WBC) comes into action and fight with that particular agent or pathogen which causes that infection. QUE-22:- Red blood cells more commonly called as Erythrocyte. QUE-23:- Erythrocyte lack a nucleus.because as more space are available to carry more haemoglobin therefore carry more oxygen , for transportation in blood. QUE-24:- If haem group were removed from haemoglobin then red blood cell would not be able to bind with oxygen because haem group contains porphyrin ring which helps in binding of 4 oxygen with haemoglobin, so if that ring would loss then oxygen can't bind with haemoglobin. QUE-25:- Venous blood is bluish in colour ,since colour appears in blood because of oxygen ,when oxygen binds with haemoglobin(Hb) then Hb changes their shape and confirmation change gives red colour but since Venous blood do not contain oxygen in their blood since it is deoxygenated hence Hb again changes their shape now this confirmation gives blue colour .there is one more fact also applied that is light has to penetrate the skin to illuminate them blue or red (being different wavelength) penetrate with different degree. QUE-15:- The greatest medical problem with the Rh group is transfusion incompatibility. As we see in case of Mother-fetus if mother have Rh(-)ve group and fetus have (+)ve group then mother's blood forms antibody against that particular blood type by considering them as a foreign (as we see in case of immune system) so it harms the second child it may leads to death of second fetus. and this Rh disease is also called erythroblastosis fetalis.
