Professor Anthony Atala is working to answer an important question: Can we grow new replacement organs rather than transplanting organs from other people? It has many functions, including filtering blood, secreting bile that is needed for digestion, and producing proteins necessary for blood clotting. The small intestine is also the main site of nutrient absorption; molecules like sugars and amino acids are taken up by cells and transported into the bloodstream for use.

It does this using: Lymph vessels Lymph nodes Lymph ducts Various glands The lymphatic vessels move the fluid into collecting ducts, which return the fluid to your bloodstream. Smooth muscle tissue layer allows to change the diameter of the arteries. After studying this unit you should know: 1 The various organs of the body.
