Final answer:
Blood cells are produced in the red bone marrow through the process of hematopoiesis, where red blood cells, white blood cells (leukocytes), and platelets are synthesized. Granulocytes are a type of white blood cell, and thus, fall under the category of leukocytes.
Step-by-step explanation:
Blood cells are produced in a special tissue known as red bone marrow. This process is referred to as hematopoiesis and occurs within some bones like the pelvis, ribs, and vertebrae. Red marrow is responsible for the synthesis of three main types of cells: red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
To answer the student's question directly:
- Where are blood cells produced? The correct answer is D. bone marrow.
- Hematopoiesis occurs in which of the following? The correct answer is B. bone marrow.
- Granulocytes, which are a type of white blood cell involved in the immune response, are part of which type of cell? The correct answer is D. leukocyte.
Hematopoiesis is an ongoing process that yields billions of blood cells every day, which are essential for carrying out a wide array of functions, such as oxygen transportation, immune response, and clotting.
