Circulatory system of the horse capacity of the muscular system far exceeds the capacity of the cardiovascular system to deliver oxygen. Blood is made up of red blood cells (erythrocytes) and white blood cells (leukocytes), as well as plasma. Produced in bone marrow, red blood cells are responsible for carrying oxygen to tissue and removing carbon dioxide, all via hemoglobin. White blood cells are used for defense against pathogens in the immune system. Plasma suspends the blood cells, contains clotting factors, and contributes to the greatest volume of blood. The heart and blood vessels contain approximately of blood in a horse, which equates to about
Furan fatty acids specifically trap hydroxyl radicals. It is therefore believed that this is in different biological systems their main function. They also inhibit the singlet oxygen-induced hemolysis of red blood cells (red blood cell disintegration). Plants and algae produce furan fatty acids during the biosynthesis from polyunsaturated fatty acids (PUFA). These are seemingly used in these organisms as protection against free radicals generated by sunlight. Occasionally it is speculated that the health-promoting properties originally attributed to omega-3 fatty acids may not be based on themself, but on the furan fatty acids also present in the fish. A clinical trial of isolated omega-3
