Blood and Bone marrow

Fibrinogen is converted to fibrin only in response to ______

Fibrin is latent in normal blood and occurs in the form of ______

Only the mature forms (erythrocytes, leukocytes) and platelets (cell fragments in mammals) or thrombocytes (cell in birds) are present in ______

Immature forms are located in blood-forming (hematopoietic) site that in adult are concentrated in the red bone ______

The most numerous cells in the circulating blood are ______

Erythrocytes have no organelles; merely bags of hemoglobin that imparts a red color to ______

Specific cytoplasmic granules are bright orange to dark pink or red. Granules are exceptionally large in ______.

Granules lysosomes (containing enzymes). Granules obscure ______.

Eosinophils increase in number during allergic reactions and helminthic infections. Basophils are believed to be absent in cats, rats, and ______.

Basophils are as large as ______.

Lymphocytes represent 20-25% of total blood cells. Three morphological types: small, medium, and ______.

Small lymphocytes are the most numerous and most important of the agranulocytes. They are quiescent in blood circulation. Structure in blood smear: round cells with a thin rim of bluish ______.

Erythrocytes are oval cells with oval nuclei ___ microns long and ___ microns wide

Heterophils are the counterpart of ___

Heterophils have a multilobed nucleus with ___ lobes

Eosinophils have a multilobed nucleus with coarsely clumped ___

Basophils are more numerous in avian ___

Thrombocytes are a distinct ___ and not a cell fragment

Erythrocytes have a biconcave shape and are non-nucleated. In a stained blood smear, they are pink staining with central pallor. These cells are also known as Red Blood Cells (RBC's) because of their ______ shape.

In a hypertonic solution, water moves from inside the cell into the solution. As a result, the cell ______.

In a hypotonic solution, water moves from the solution to inside the cell. This leads to the cell swelling and eventually ______.

In an isotonic solution, the concentration of solutes in the solution is equal to the concentration of solutes inside the cell. This results in water moving equally in both directions, maintaining a ______ size of the cell.

Howell-Jolly bodies are non-refractile nuclear remnants that can be seen in equine and feline red blood cells. They are a characteristic feature observed in these types of ______.

Leukocytes, or White Blood Cells (WBC), are true cells with nuclei and organelles, unlike erythrocytes which are non-nucleated. WBCs play a crucial role in the body's ______ system.

Cytoplasm of young cell is basophilic due to abundant ______ and become acidophilic with maturation due to increase in hemoglobin content.

Mitotic activity is high in very young cells but not common in ______ cells.

Erythropoiesis is the development and maturation of ______.

Myelopoiesis or granulopoiesis is the development and maturation of ______ (neutrophils, eosinophils, and basophils).

Thrombopoiesis is the development of platelets in mammals and ______ in birds.
