Answer: To increase arterial pressure you need to increase the cardiac output
Explanation:
Cardiac output is the volume of blood being pumped by the heart in one minute. It is equal to heart rate multiplied by stroke volume.
Two factors affect the strength of the blood: cardiac output and peripheral resistance. Cardiac output is the volume of blood circulated by the heart. Increasing heart rate also results in increased cardiac output, which increases blood pressure.
Cardiovascular system is often compared to a city.
A phrase to describe a negative feedback loop could be: self-regulating (though I'm not sure the exact word you're looking for).
Answer:
The antibiotic used to fight the body's bacteria and classified as a quinolone is Floxin.
Explanation:
Floxin is the commercial name of Ofloxacin, a 2nd generation quinolone used in the treatment of infections by gram positive and gram negative germs. Its mechanism of action is to inhibit enzymes important for bacterial development, such as DNA gyrase and Topoisomerase IV.
Ofloxacin can be used for infections of the eyes, ears, skin and genitourinary system, including some sexually transmitted infections. Other 2nd generation quinolones are ciprofloxacin and norfloxacin.
Ofloxacin comes in tablets form, so it is only administered orally.
