Wandering cells are
-
Histiocytes
-
Mast cells
-
Leukocytes
-
All of the above
The term wandering cell (or ameboid cell)[1] is used to describe cells that are found in connective tissue, but are not fixed in place. This term is used occasionally and usually refers to blood leukocytes (which are not fixed and organized in solid tissue) in particular mononuclear phagocytes.
Number of WBCs per $mm^3$ of human blood is ideally.
-
$8000$
-
$7000$
-
$6500$
-
$6000$
Number of leucocytes in decreasing order in human blood is?
-
Eosinophils $>$ basophils $>$ neutrophils
-
Neutrophils $>$ eosinophils $>$ basophils
-
Basophils $>$ eosinophils $>$ neutrophils
-
Eosinophils $>$ neutrophils $>$ basophils
Basophils: 0.5–1.0 percent. Eosinophils: 1–4 percent. Lymphocytes: 20–40 percent. Monocytes: 2–8 percent, Neutrophils: 40% to 60% Lymphocytes: 20% to 40%.
Find the correct descending order of percentage proportion of leucocytes in human blood.
-
Neutrophils --> Basophils --> Lymphocytes Acidophils (Eosinophils) -->Monocytes
-
Monocytes --> Neutrophils --> Lymphocytes --> Acidophils-->Basophils
-
Neutrophils --> Lymphocytes Monocytes --> Acidophils -->Basophils
-
Lymphocytes Acidophils --> Basophils --> Neutrophils-->Monocytes
The relative proportions of the different types of white blood cells are: Neutrophils (roughly 60 – 70%), Lymphocytes (roughly 20 – 30%), Monocytes (approximately 1 – 6%), Eosinophils (approximately 1 – 3%), Basophils (less than 1%).
Thus, the correct answer is 'Neutrophils --> Lymphocytes Monocytes --> Acidophils -->Basophils.'
Compounds released by WBCs, which raise the body's temperature, are known as
-
Insulin
-
Catecholamines
-
Pyrogens
-
Prostaglandins
Immunocomplexes are removed by
-
Basophils and monocytes
-
Basophils and eosinophils
-
Eosinophils and monocytes
-
Neutrophils and basophils
Immunocomplexes also called antigen-antibody complexes are harmful and long deposition of then inside the cell can lead to various autoimmune disorders and primarily removed from the cell by phagocytosis in which eosinophils and monocytes (destruction of antibody) have an important role to play.
In a blood sample, a WBC has a nucleus with drum-sticks. This indicates that the blood sample has come from a person who is
-
Heamphilic
-
Diabatic
-
Female
-
Sickle cell-anemic
Neutrophils are sexually dimorphic. Neutrophils from females exhibit a small additional X chromosome structure, known as a "neutrophil drumstick".
Which of the following cells are associated with immune system of body?
-
Platelets
-
WBC
-
Macrophages
-
RBC
Select the incorrect statement out of the following.
-
Neutrophils constitute the majority of leucocytes
-
Eosinophils resist infection.
-
Basophils secrete histamine and serotonin.
-
RBCs in mammals are enucleated and biconvex in shape.
Mark, among the following the a cell which does not exhibit pahgocytotic activity
-
Monocytes
-
Neutrophil
-
Basophil
-
Macrophage
Phagocytotic activity is the process of engulfing or ingestion of food or bacteria.
- Monocytes - They are the largest type of leucocytes present in about 10-20% in blood. They are phagocytotic in nature and engulf bacteria.
- Neutrophils - There are also many in number in leucocytes. They are phagocytotic in nature and thus engulf harmful bacteria and germs.
- Basophils - They are present in the very least amount in the leucocytes. Their main function is the prevention of blood clotting and other allergic reactions.
- Macrophages - They are formed from monocytes in the leucocytes. They are phagocytes that engulf and destroy all the bacteria.
So, the correct option is 'Basophil'.
