k so the adrenal medulla which is a gland located on top of your kidneys release these nonpituitary hormones called epinephrine and norepinephrine which helps dilate blood vessels to allow oxygen and glucose to come in. Then your sympathetic nervous system releases even more norepinephrine (this is an example of positive feedback mechanism). So your digestive lining's vessels constrict and no oxygen is there. That's why when ur in fight or flight situations your body stops metabolizing.

Explain negative feedback and its role?
Negative feedback is a corrective mechanism in biological systems where the response to a stimulus results in the inhibition of that stimulus. It helps to maintain homeostasis by counteracting any deviations from the set point. For example, in the regulation of body temperature, negative feedback helps to prevent overheating or hypothermia by signaling the body to either produce more or less heat.
Feedforward feedback control?
Feedforward is a preparatory control. EX. Smelling food leads to salivation and production of stomach acid in preparation of food. OR Starting to exercise increases heart rate and breathing rate in preparation of running low on oxygen for muscles. Feedback is a control mechanism where the product of the end mechanism either enhances or inhibits the start of the mechanism Positive feedback enhances Negative feedback inhibits
What organs are involved in the feedback mechanism responsible for regulating blood pressure?
The kidneys, heart, blood vessels, and brain are involved in the feedback mechanism that regulates blood pressure. The kidneys help control blood volume and release hormones that affect blood pressure, while the heart adjusts its rate and strength of contraction. Blood vessels can constrict or dilate to regulate blood flow, and the brain receives signals and sends instructions to maintain blood pressure homeostasis.
What mechanisms are involved in homeostatic mechanisms?
homeostatic mechanisms involve: - the regulation of blood glucose - breathing rate - heart rate - oxygen levels - osmoregulation (water levels) - thermoregulation (temperature control)
Can you think of an example other than body heat where a negative feedback loop is utilized with the body?
Increased blood sugar will cause insulin production to rise and the cells will store the excess sugar, increased blood pressure causes a slower heart rate and decrease in oxygen levels will increase red blood cell production.
What is mechanism of CARP?
The mechanism of CARP is the regulation of the blood glucose, breathing rate, and heart.

Does negative feedback regulate heart and breathing rates?
of course silly heads you see, the heart r specific body parts in your ubela, which contains acids that make u retard.
What hormone works as a negative feedback to aldosterone?
Atrial natriuretic peptide (ANP) works as a negative feedback to aldosterone. ANP is released from the atria of the heart in response to high blood volume and works to decrease sodium reabsorption in the kidneys, opposing the actions of aldosterone.
What is the difference between positive feedback control system negative feedback control system?
Positive feedback speeds up reactions and negative feedback slows them down. In electronics and control systems, positive feedback means the feedback gets added to the input and then goes as output. And negative feedback means that the output is input minus feedback (from output). This is the most basic and layman answer I can think of. In social and business terms, a positive feedback means a good response ( a praise for a product, or interest generation among the clients) and a negative feedback means a bad response (unhappy clients, criticism and the like ).

Mechanism for beta antagonist receptors on the heart?
Decrease heart rate & increase cardiac output
Explain the probable homeostatic responses to changes in the internal environment during exercise?
during exercise, your skeletal muscles metabolize faster hence they require more oxygen and nutrients than when they are in the resting phase. as a result of this, the heart pumps blood faster and harder to compensate for this demand. in addition, since the heart works double time to supply blood, the lungs also take in more oxygen and your breathing rate gets high so you tend to hyperventilate also. aside from that, your energy and fluid stores also gets depleted especially during intense workout so you tend to feel hungry and thirsty after.
What law of the heart is mechanism that ensures the volume of blood discharged from the heart is equal to the volume entering its chambers?
stallings
Where does the regulation of autonomic function such as heart rate and blood pressure originate?
Medulla oblongata
What is the proper term for heart attack what is the mechanism?
Proper Term: Cardiac Arrest
