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.
