Question

Compare the processes of red blood cell production, white blood cell production, and platelet production. drop the labels into the appropriate boxes. labels may be used more than once.

Answer 1

In hematopoiesis, red blood cells, white blood cells, and platelets are produced in the red bone marrow. Red blood cells transport gases and live about 120 days, white blood cells defend the body, and platelets aid in blood clotting.

Step-by-step explanation:

Comparison of Blood Cell Production Processes

The hematopoiesis process involves the production of red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes) in the red bone marrow. Erythrocytes, the most abundant cells in our blood, are designed for oxygen and carbon dioxide transport due to their hemoglobin content. Their lifespan is about 120 days, necessitating continuous replacement. Hemoglobin molecules breakdown into amino acids, iron, and heme, with iron being reused or stored, and heme converted into bilirubin.

Leukocytes are crucial for the body's defense mechanisms. They can move out of blood vessels to target areas of infection or threat. They originate from both myeloid and lymphoid lineages in the bone marrow, resulting in different types, including neutrophils, eosinophils, basophils (from myeloid), and lymphocytes such as B cells, T cells, and NK cells (from lymphoid).

Platelets are cell fragments from megakaryocytes and play an essential role in blood clotting and wound healing. While many platelets are stored in the spleen, others circulate in the blood to carry out their functions. Hemopoietic growth factors like erythropoietin, thrombopoietin, and colony-stimulating factors facilitate the proliferation and differentiation of these blood components.

Answer 2

Attached is the image containing the correct labels as well as an image concerning the different cell lines involved in hematopoiesis.

Red blood cell production is stimulated by erythropoietin which is produced by the kidneys. Increases in erythropoietin production also increases the production of hemocytoblasts or myeloid cell precursors. Red blood cell maturation occurs in the red bone marrow. Red blood cell production is from the myeloid stem line (along with white blood cells, except lymphocytes, and platelets).

White blood cell production is triggered when there is increases in interleukins and colony stimulating factors (i.e. infection). This will also increase the production of hemocytoblasts and also develop in the red bone marrow. White blood cells are neutrophils, eosinophils, basophils, and monocytes which are all from the myeloid stem cells. Lymphocytes on the other hand come from the lymphoid stem cells.

Platelet production is primarily stimulated by thrombopoietin which is produced by the liver. They also develop from hemocytoblasts which then will differentiate to megakaryocytes (that develop in the bone marrow). Fragmentation of megakaryocytes will produce platelets.
