What do we call alterations in body systems during a stress response?

Physiologic changes are the alterations that occur in body systems during a stress response. When an animal experiences stress, the body activates a complex series of hormonal and physiological processes, often referred to as the fight or flight response. This can include increased heart rate, changes in respiratory rate, alterations in immune system functioning, and the release of stress hormones such as cortisol and adrenaline.

These changes are crucial for the animal's ability to cope with perceived threats or challenges in their environment. They prepare the body for quick responses, which can be vital in stressful situations. Understanding these physiologic changes is essential for veterinary professionals to effectively recognize and manage stress in animals, ensuring a better overall welfare and more positive experiences during veterinary visits.

Other options pertain to different aspects of stress and behavior but do not specifically focus on the direct alterations in body systems in response to stress.
