  • What are the two types of bone marrow, and what are their primary functions?
    The two types of bone marrow are red marrow, which is responsible for hematopoiesis (the production of blood cells), and yellow marrow, which serves as a storage site for fats (triglycerides).
  • How does the distribution of red and yellow bone marrow change from infancy to adulthood?
    Infants have mostly red marrow to support rapid blood cell production, while adults have mostly yellow marrow, with red marrow remaining primarily in the spongy bone.
  • Under what conditions can yellow bone marrow revert to red bone marrow, and why is this important?
    Yellow marrow can convert back to red marrow when there is an increased demand for blood production, such as in cases of severe blood loss or anemia, to help the body produce more blood cells.
  • What are the two types of bone marrow found inside bones?
    The two types are red marrow, which produces blood cells, and yellow marrow, which stores fat (triglycerides).
  • Where is red bone marrow primarily located in adults?
    In adults, red marrow is primarily found in the spongy bone.
  • What is the main function of red bone marrow?
    Red bone marrow is responsible for hematopoiesis, the production of blood cells.
  • How does the amount of red and yellow marrow change from infancy to adulthood?
    Infants have mostly red marrow to support rapid blood cell production, while adults have mostly yellow marrow, with red marrow mainly in spongy bone.
  • What is the primary function of yellow bone marrow?
    Yellow bone marrow serves as a storage site for fats (triglycerides).
  • In which parts of the bone is yellow marrow found?
    Yellow marrow is found in both the spongy bone and the medullary cavity of long bones.
  • Under what conditions can yellow marrow revert to red marrow, and why is this important?
    Yellow marrow can revert to red marrow when there is an increased demand for blood production, such as during severe blood loss or anemia, to help the body produce more blood cells.
