Answer:
Negative feedback.
Explanation:
Body's homeostasis is maintained by two feedback mechanism known as positive feedback and negative feedback. Most processes in our body is controlled by the negative feedback mechanism.
The negative feedback mechanism in which the final product of the reaction decreases the further secretion of that product. In case of the body temperature rise, brain canter decreases the body temperature is controlled by negative feedback. The high level of the substance decreases its further secretion in case of maintenance of body temperature.
Thus, the correct answer is option (c).
Answer:
The correct option is : a. causing threshold to be reached more quickly
Explanation:
Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.
It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.
Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>
Many of the symptoms that make a person suffer during an infection—fever, malaise, headache, rash—result from the activities of the immune system trying to eliminate the infection from the body. In response to infection, your immune system springs into action.
