The term that best describes the process of taking in substances gradually is absorption. Absorption refers to the process by which substances, such as nutrients, are taken in by the body through various means, often occurring at a cellular level. This gradual uptake allows the body to assimilate necessary nutrients and fluids from the digestive system into the bloodstream or tissues.

While ingestion involves the act of taking substances into the body, typically through the mouth, it does not imply the gradual absorption process that occurs afterward. Assimilation refers more to the integration of these substances into the body after they have been absorbed, rather than the act of taking them in. Consumption is a broader term that can refer to using resources, including food or drink, but does not specifically denote the gradual uptake of substances in the way absorption does.
