Seabirds have salt-excreting organs above their eyes which enable them to drink salty water; sea snakes have a similar filter at the base of their tongue.
The albatross drinks sea water. It has a special desalinization apparatus that strains out and excretes all excess salt.
THERE MUST BE A BIO CHEMICAL EXCRETION PROCESS AND NOT A MERE FILTERING STRUCTURE TO EXCRETE SALT . SO WHAT IS THAT /ARE THOSE BIO CHEMICAL/S OR CHEMICAL /S THAT HELP THIS PROCESS PROBABLY THAT CAN HELP HEART PATIENTS?
