Which of the following statements about blood cells are not correct?
1.Neutrophil is the rarest form of leukocyte present in the circulation in humans.
2.Lymphocytes, a larger leukocyte are the most abundant leukocyte type in circulation in humans.
3.Monocytes are a type of macrophages and can be identified by their typical 2 lobe appearance.
4.Platelets are larger fragments formed from the megakaryocytes in the bone marrow.
5.Leukocytes are active only in the circulation. 6.Average lifespan of leukocytes is 120 days.
-Statements 1,2,4,5,6 are incorrect
---None of the mentioned statements are incorrect
---All of the mentioned statements are incorrect
--Only statements 1.2.3.4 are incorrect.
Blood clotting is a homeostatic response. When clotting is poor, even a slight injury to a blood vessel may lead to severe blood loss. When clotting is excessive, small blood vessels in critical places in the body can become clogged leading to clots. Excessive bleeding or excessive clotting both can be dangerous.
– Describe the main stages in the formation of a blood clot and evaluate the importance of specific factors example platelets, vitamin K, air and blood proteins
Injured tissue – exposure of endothelial cells
Narrowing (constriction) of blood vessels
Activity of platelets
Activity of clotting factors
