Digestion: It’s the breakdown of the swallowed food into minuscule and finally molecular fragments. Most ingestion occurs in the stomach, and a small part also appears in the tiny intestines.
Absorption: This is often a critical phase in which the nutrients are taken up from digestive organs and distributed to the body’s tissues. This process is where food swallowed is transformed into actual energy used in human forms.
Excretion: This is the last process where left-over material excretes from our bodies.
