Hello. This question is incomplete. The full question is:
"How does inflammation help the body fight off further infection?
A. Inflammation keeps harmful substances away from healthy cells. B. Inflammation triggers the production of white blood cells. C. Inflammation drops the pH of blood. D. Inflammation raises the pH of blood."
Answer:
A. Inflammation keeps harmful substances away from healthy cells.
Explanation:
Inflammation is a normal reaction of the immune system to an aggression in the body that must be neutralized or eliminated. It can be generated by infections of bacteria, viruses and other parasites, in addition to other factors such as heat, physical trauma and exposure to radiation and irritating chemicals.
Inflammation helps the body fight other infections because it keeps harmful substances away from healthy cells.
The inflammatory process leads the body to produce five classic signs: heat, redness (redness), tumor (swelling, edema), pain and loss of function. Heat and redness are caused by the dilation of the vessels and the increase in local blood flow leads to reddish color. Swelling arises from the release and accumulation of fluids.

Hope this helped its different for everyone what was it for u it was A for me
Answer:
Here are some explanations from 0nline so if you want rewrite in your own words
hope this helps :))
blood glucose-
"The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels."
"If the blood glucose level is too low, the pancreas releases the hormone glucagon. This travels to the liver in the blood and causes the break-down of glycogen into glucose. The glucose enters the blood stream and glucose levels increase back to normal. This is an example of negative feedback."
body temperature-
" Body temperature is regulated by negative feedback. The stimulus is when the body temperature exceeds 37 degrees Celsius, the sensors are the nerve cells with endings in the skin and brain, the control is the temperature regulatory center in the brain, and the effector is the sweat glands throughout the body."
"Body temperature is controlled by the hypothalamus in the brain. If the hypothalamus detects that the body is too hot, the response is that the body begins to sweat to try and reduce the temperature back to the correct level."
"Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances."
"Negative feedback brings a system back to its level of normal functioning. Adjustments of blood pressure, metabolism, and body temperature are all negative feedback"
B. Internal respiration occurs.
C. Ribs and diaphragm muscles contract.
D. Inspiration occurs.
Answer:
The correct answer is option A.
Explanation:
Breathing is the exchange of air through the involved passages in between the atmosphere and the lungs. Inspiration is a process where we take air into the lungs from the atmosphere also known as inhalation.
Expiration is releasing air out of the lungs to the atmosphere. In expiration, the diaphragm relaxation and elastic recoil of tissue decrease the thoracic volume of lungs. That results in an increase the intraalveolar pressure in the lungs.
Thus, the correct answer is option A.
