Answer
In adults, the yellow marrow stores fat.
Solution
1. The red bone marrow is responsible for forming blood cells (a process called hematopoiesis).
2. The yellow bone marrow, however, is primarily composed of adipocytes (fat cells) and serves as a storage site for fat.
3. Lengthwise growth of long bones occurs at the epiphyseal plates (growth plates), not in the yellow marrow.
Thus, in adults the function of yellow marrow is to store fat, not to form blood cells, store calcium and phosphorus, nor promote lengthwise growth in long bones.

Yellow marrow primarily serves as a storage site for fats, but it also plays a role in providing energy. It is found in the hollow interior of long bones and can convert to red marrow if there's an increased demand for blood cell production, such as during an illness or recovery from blood loss. So, it’s like having a reserve team ready to jump into action! Interestingly, when we think of bones, we often picture them as solid structures, but they’re dynamic and alive! Aside from storing fats, yellow marrow helps maintain bone health by releasing energy, and it’s even linked to the regulation of certain hormones. This means your bones are multitasking!
