The stem of the vegetable
Answer:
FALSE
Explanation:
a noncommunicable disease is one that CANNOT be passed to others. <u>The flu is an infectious virus that can be easily spread via germs therefore communicable</u>
True!
Just above the spinal column is the medulla oblongata, and it controls several important automatic tasks. Breathing is one of the most crucial. Rhythmic breathing is regulated, along with variations due to changing body needs, such as running. You do not have to think about breathing faster; the medulla takes care of that for you. Heart rate is another vital function that is centered in this area. The medulla will increase or decrease the beat based on information from other parts of the body. The medulla also determines when blood vessels should constrict to reduce blood flow.
The correct answer is: Baroreceptors in the arteries send a signal to the brain that the blood pressure is low. The brain sends a chemical signal to the heart to increase its rate of pumping. This continues until the baroreceptors sense a normal blood pressure.
A negative feedback loop occurs in the body when something in the body has decreased in function, which could mean high or low, for example blood sugar, body temperature or in this in this case blood pressure. It then creates a feedback loop to tell that part of the body to regulate itself and return the body to a state of homeostasis (which is your optimal internal state). In a negative feedback loop the response of the regulating mechanism is opposite to the output of the event. So if blood pressure is low the negative feedback loop will tell the body to increase the pressure.
A positive feedback will result in more of a product: more prolactin, more contractions, or more clotting platelets.
