Answer

Yellow marrow in adults primarily stores adipose tissue.

Solution

To solve the problem, we need to identify the primary function of yellow marrow in adults. Let's analyze the options provided: 1. **Store adipose tissue**: Yellow marrow primarily consists of fat cells (adipocytes) and serves as a storage site for adipose tissue. 2. **Form blood cells**: This function is primarily associated with red marrow, not yellow marrow. Yellow marrow does not play a significant role in blood cell formation in adults. 3. **Store calcium and phosphorus**: While bones do store minerals like calcium and phosphorus, this is not a specific function of yellow marrow. 4. **Promote lengthwise growth in long bones**: This function is related to the growth plates (epiphyseal plates) in long bones, not yellow marrow. Based on this analysis, the correct answer is: **Store adipose tissue**. Yellow marrow's main function in adults is to store fat.

Beyond the Answer

The yellow marrow primarily acts as a fat storage reservoir in adults, rich in adipose tissue. This stored fat can serve as an energy source during times when the body requires extra fuel, such as during prolonged periods of fasting or extreme physical exertion. So, in a sense, your body’s own little stash of energy bars just waiting to be used! While the red marrow is primarily tasked with blood cell production, the yellow marrow’s role is generally less about making blood and more about providing energy reserves. However, it can convert back to red marrow and start forming blood cells again if the body is under stress, such as in cases of severe blood loss. Pretty multifunctional for something we often overlook!
