Using your knowledge of the heart, blood vessels and factors affecting
blood pressure, create a possible reflex control/feedback loop that would
occur if a person's blood pressure suddenly decreases. Include all of the
elements of a feedback loop. Your answer can simply be a list of steps that
would occur, but make sure to indicate all of the elements of a feedback
loop. This does not to be extremely detailed, I am looking for the elements
of the feedback loop and to see that you understand the factors affecting
blood pressure.
I will start the loop:
1. Stimulus: Drop in blood pressure.

- Which statements describe how systems interact to produce the fight-or-flight response?Select the two correct answers. A The digestive system interacts with the excretory system, supplying hormones to slow the production of urine. B The endocrine system floods the circulatory system with hormones that affect several other body systems. C The endocrine system supplies the lungs with insulin, allowing increased absorption of oxygen. D The digestive system creates hormones that are sent to the muscular system, resulting in increased blood flow to muscles. E The muscular system sends receptors to the circulatory system to increase blood pressure and heart rate. F The circulatory system experiences a change in blood flow, which allows the muscular system to obtain additional glucose.arrow_forwardGive an example of a feedback mechanism in the human body.

- How would antibodies against nicotinic acetylcholine receptors (nAChRs) affect the influx of sodium (Na+) into a skeletal muscle cell? Group of answer choices These antibodies would target nAChRs for destruction leading to lower sodium influx in muscle cells. These antibodies would target nAChRs, changing their shape to allow calcium instead of sodium through. These antibodies would target nAChRs, changing their shape to allow only potassium through. These antibodies would target nAChRs aiding acetylcholine in its binding to receptors, leading to increased sodium influx in muscle cells. pick one answerarrow_forwardCompare and contrast the nervous and endocrine system as to their coordination and control of the body systems in animals (use table or venn diagram)arrow_forwardIt is a warm, summer day and you are out for a walk.
