Detailed explanation-1: -Pinocytosis (“pino” means “to drink”) is a process by which the cell takes in the fluids along with dissolved small molecules. In this process, the cell membrane folds and creates small pockets and captures the cellular fluid and dissolved substances.

Detailed explanation-2: -Pinocytosis refers to the uptake of extracellular fluids and dissolved solutes, such as fat droplets, vitamins, and antigens. The term pinocytosis is derived from the Greek word “pino, ” meaning “to drink, ” and “cyto, ” meaning “cell.” Therefore, the process of pinocytosis can be thought of as cellular drinking.

Detailed explanation-3: -Examples of Pinocytosis Microvilli in the gut use this process to absorb nutrients from food. Cells in the kidney can use pinocytosis to separate nutrients and fluids from the urine that will be expelled from the body. In addition, human egg cells also use it to absorb nutrients prior to being fertilized.

Detailed explanation-4: -The main function of pinocytosis is to absorb extracellular fluids. It plays an important role in the uptake of nutrients along with the removal of waste products and signal transduction.

Detailed explanation-5: -One specific form of endocytosis is called pinocytosis which is also known as “cell drinking”. This may give you a hint on what type of content is internalised in this process, right? As you may have guessed, during pinocytosis, the cell captures fluids like water and solutes.
