Verified step by step guidance1
Identify the role of the endocrine system: The endocrine system is responsible for releasing hormones into the bloodstream to regulate various body functions such as metabolism, growth, and mood.
Understand the concept of 'overriding' in physiological terms: Overriding refers to the ability of one system to take control or alter the function of another system.
Consider the systems listed: digestive, nervous, circulatory, and reproductive. Each of these systems has specific functions and interactions with the endocrine system.
Analyze the nervous system's role: The nervous system can directly influence the endocrine system through the hypothalamus, which controls the pituitary gland, often referred to as the 'master gland' of the endocrine system.
Conclude that the nervous system is capable of directly overriding the endocrine system, as it can rapidly alter hormone release in response to stimuli, unlike the other systems listed.
