i think it depends on what type of nutrients it is eg. fat is stored in different places to carbs and proteins, etc.
Nutrients are units of blocks that build the body, in most of the case, they are not stored but assimilated inside the body. The nutrients in the body are carried in the blood and assimilated through out a body. some nutrients like glucose are temporarily stored in the liver.
Any energy-yielding nutrients that are ingested in excess will be stored as body fat.

True
Excess nutrients are stored as fat and glycogen. There is no storage form of a similar nature for protein, but fasting mobilizes amino acids from muscle that would later be replenished or rebuilt over time. Similarly bone will leach calcium and minerals but that deficit creates a 'debt' to those tissues that the body will try to repay when concentrations of precursors rise again.
Excess nutrients are stored in the body as energy reserves in the form of glycogen in muscles and the liver, and as triglycerides in adipose tissue. These reserves can be used by the body when needed for energy production.
Energy-yielding nutrients consumed in excess, particularly carbohydrates and fats, can lead to storage of fat. When these nutrients are not utilized as immediate energy, they are converted and stored as fat in the body for later use.
Nothing is stored in the human bowels unless a person has a problem with his or her digestive system which prevents them from eliminating feces. Nutrients the body absorbs through the bowels are not stored.
Fats
Calorie containing nutrients--fats, carbohydrates, and protein, are stored as fat if not used as energy by the body.
The nutrients stored in body cells and converted into the major fuel source for muscles are primarily carbohydrates, specifically glycogen, and fats. Glycogen is stored in the liver and muscle tissues, while fats are stored in adipose tissue. During physical activity, these nutrients are metabolized to provide energy, with glycogen being the preferred source for high-intensity exercise and fats being used more during prolonged, low-intensity activities.
