Document Summary

Paths of nutrients in the body: digestion and absorption, transport through body , function and metabolism in the cells and organs , elimination of metabolic wastes. Where we are from last video: nutrients are ready to enter blood stream or lymphatic system. The transport of nutrients depends on the cardiovascular system, a network of vessels through which blood is pumped.

Fat soluble components are packaged into chylomicron particles, enter the lacteal, the lymphatic system, then enter the blood stream, tissues and organs, before reaching the liver. The lymphatic system mainly functions as part of the immune system as lymphocytes or white blood cells circulation through its vessels.
