Verified step by step guidance
1
Step 1: Understand the question by identifying the key focus, which is determining the system responsible for the creation of blood cells in the human body.
Step 2: Recall that blood cell production is a process called hematopoiesis, which primarily occurs in the bone marrow.
Step 3: Recognize that the bone marrow is part of the skeletal system, which houses the hematopoietic tissue responsible for producing red blood cells, white blood cells, and platelets.
Step 4: Eliminate the other options by understanding their primary functions: the respiratory system is responsible for gas exchange, the digestive system processes food and absorbs nutrients, and the hematopoietic system is not a distinct system but rather a process within the skeletal system.
Step 5: Conclude that the skeletal system is the correct answer because it contains the bone marrow where blood cell production occurs.
