5. Small intestine

6. Large intestine

Explanation:

1. Liver is a large, infact the largest, organ found in the digestive system. It has variety of functions ranging from detoxification to digestion. The liver functions in digestion by secreting a substance called BILE which helps in the breakdown of fat in the small intestine.

2. Pancreas is another accessory digestive organ which serves as a endocrine organ which secretes enzymes that aid in the digestion of protein and carbohydrate molecules.

3. Lungs are respiratory organs whose function is key to the respiratory system. They are the organs that serve as a medium of the entry of oxygen and removal of carbon dioxide, a process called GAS EXCHANGE.

4. Saliva is a liquid substance secreted by the salivary gland in the mouth. Saliva contains certain enzymes; most notably is the AMYLASE that breaks down starch into sugar.

5. Small intestine is another organ in the digestive system composed of the ileum, jejenum and duodenum. The small intestine is the organ where the absorption of nutrients into the blood from the digested food takes place.

6. Large intestine is the extension of the small intestine whose function is to absorb extra water from undigested food and pass out the remaining as feaces.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
