Hints
1.
Antibodies are immunoglobulins (a type of proteins) which act against germs or their secretion and destroy them. Antibodies are produced by lymphocytes on exposure to antigens.
An antibiotic is a chemical substance produced by living organisms which can stop the growth of some disease-producing bacteria and fungi.
E.g.: (i) Penicillin is used for the treatment of tetanus (ii) Streptomycin is used for the treatment of tuberculosis.
2. The heart supplies oxygenated blood to itself via the coronary arteries.
