The correct answer is C. pancreas.
Here's an explanation of why the pancreas does not release hormones into the bloodstream during a stress response:
1. The pituitary gland, adrenal gland, and hypothalamus are all involved in the body's stress response by releasing hormones such as cortisol and adrenaline into the bloodstream.
2. The pancreas, although an important gland in the body, is not primarily involved in releasing stress hormones during a stress response. Instead, the pancreas plays a key role in regulating blood sugar levels by producing insulin and glucagon.
3. During a stress response, the focus is on activating the body's fight-or-flight response through the release of hormones that prepare the body to respond to a perceived threat. This response is primarily orchestrated by glands such as the pituitary, adrenal, and hypothalamus, rather than the pancreas.
In summary, the pancreas does not release hormones into the bloodstream during a stress response, making it the correct answer in this case.
