What changes occur in the composition of blood in the capillaries of a large circle of blood circulation in humans? What kind of blood is formed? What process contributes to the slow flow of blood in the capillaries?

1) blood in the capillaries of a large circle of blood circulation gives off oxygen and is saturated with carbon dioxide;
2) in the capillaries of a large circle of blood circulation, nutrients pass from blood to tissue fluid, and metabolic products – from tissue fluid to blood;

4) the slow flow of blood in the capillaries contributes to the complete metabolism between blood and body cells.
