Digestion is the process of breaking down food into smaller components that can be absorbed by the body.

• Ingestion: Food is taken into the mouth.

• Mechanical digestion: Chewing breaks down food into smaller pieces.

• Chemical digestion: Enzymes in saliva start breaking down carbohydrates.

• Peristalsis: Muscles in the esophagus push food to the stomach.

• Stomach: Acids and enzymes further break down food.

• Small intestine: Nutrients are absorbed into the bloodstream.

• Large intestine: Water...read more

Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration through a semi-permeable membrane.

• Osmosis is a type of passive transport in cells.

• It helps maintain the balance of water in living organisms.

• Examples include the movement of water into plant roots from the soil and the movement of water into animal cells.

• Osmosis can cause cells to swell or shrink depending on the concentration of solutes in the surrounding environment...read more

Digestion is the process of breaking down food into smaller components that can be absorbed by the body.

• Digestion starts in the mouth where food is chewed and mixed with saliva.

• Food travels to the stomach where it is further broken down by stomach acids and enzymes.

• Nutrients are absorbed in the small intestine, while waste products move to the large intestine for elimination.

• Examples of digestive enzymes include amylase, protease, and lipase.
