Anatomy and Physiology II Practice Test

Which connective tissues are involved in making blood cells?

1. Myeloid and Lymphatic

2. Adipose and Cartilage

3. Fibrous and Epithelial

4. Loose and Dense

The correct answer is: Myeloid and Lymphatic

The correct answer, myeloid and lymphatic, refers to the specific types of connective tissues involved in the hematopoietic process, which is the formation of blood cells. Myeloid tissue is found in the bone marrow and is responsible for producing red blood cells, white blood cells, and platelets. Lymphatic tissue, on the other hand, is involved in the production and maturation of specific types of white blood cells that are crucial for the immune response. Myeloid tissue contains hematopoietic stem cells that differentiate into various blood components, while lymphatic tissue plays a key role in the immune system, contributing to the defense against pathogens. This combination underscores the importance of both tissue types in the overall process of blood cell formation. In contrast, the other options do not directly participate in blood cell formation. Adipose and cartilage tissues serve different functions, primarily related to fat storage and structural support, respectively. Fibrous and epithelial tissues also have distinct roles, focusing on connective strength and lining surfaces or cavities, rather than blood cell production. Lastly, loose and dense connective tissues provide support and attachment, but do not have the specialized functions required for hematopoiesis.
