How feedback mechanisms help maintain homeostasis?
They control Events.
What are the compensatory mechanisms that are acting to maintain blood pressure in the face of blood loss?
An increase in cardiac output (heart rate x stroke volume) is the main acute compensatory mechanism. There is also constriction of blood vessels to increase total peripheral resistance and maintain central bp. In the more long term, activation of the renin-angiotensin system helps to maintain fluids by reabsorbing sodium and water, releasing aldosterone and promoting thirst. Organs like the liver and the spleen, which act as blood stores, contract to put more blood into circulation. Blood is also diverted away from all systems not considered vital.
What is an example or definition of a compensatory response?
Let's say your father tells you you can't use your telephone after 10 PM. So you get onto your computer and do text messaging through the computer instead.From, sugarspicecake - The definition for Compensatory Response: If a drug changes bodily functioning in a certain way, say by increasing heart rate, the brain will try to adjust for this imbalance by producing compensatory responses, which are reactions opposite to that drug (for example: reactions that decreases heart rate). In effect, compensatory responses represent the body's way of fighting the invasion of drugs. Therefore, the compensatory responses, try to keep the peace in a person's body, or the compensatory reponses try to maintain a homostatis balance in the body.
Why are kidneys homoeostatic?
they help to maintain fluid balance levels through the use of feedback mechanisms.
How do feedback on mechanisms help maintain homestsasis?
That's negative feedback. Positive feedback ruins homeostasis.
What are the main activities of the KKK?
The main activities of the KKK centered on attempting to maintain white supremacy.
What are mechanisms of homeostasis'?
The processes and activities that help to maintain homeostasis are referred to as homeostatic mechanisms. for example regulation of blood pressure, regulation of pH in the body fluids and regulation of blood glucose levels.
Which type of controls are used to implement and maintain passwords identification authentication and access control mechanisms?
technical controls
Which feedback mechanisms maintain equilibrium of systems like turgor pressure temperature and chemical reactions?
both negative and positive feedback
Who was tension between during the Boston massacre?
The Patriots were attempting to demonstrate against British taxation, and the soldiers were there to maintain order.
What is an overloaded boat?
This is a generalised term commonly used to describe weight, number of persons or both exceeding the maximum limits set by the manufacture or legal governing body/licence. In a broader sense when weight exceeds acceptable buoyancy to maintain appropratie level of vessel operation in the given conditions that could be considered overloaded.
What mechanisms did elaine's body employ to maintain homeostatsis?
Elaine's body likely used various mechanisms to maintain homeostasis, such as temperature regulation through sweating or shivering, hormone regulation through the endocrine system, and fluid balance through the kidneys. Additionally, feedback loops involving the nervous system may have played a role in maintaining equilibrium in her body systems.
