Capillaries are tiny thin-walled blood vessels that connect the smallest arteries and veins and allow the exchange of nutrients and waste between the blood and tissues.
However, one must take into account the reality of patient behavior and the price of unsuccessful or incomplete therapy. Three to six days of oral antibiotics for children with streptococcal throat infection is a safe treatment with a comparable effect to the standard duration of 10 days of penicillin.

Penicillin is often the first choice of antibiotic for strep throat unless you are allergic to it. Most antibiotics are taken for 10 days. Or a single shot of penicillin may be given. The shot does not help you get better any faster than other types of penicillin.
