What body system breaks down food into simple substances?

What body system breaks down food into simple substances?

The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

What is the thing that digests food?

Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices. Pancreas. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins.

What process breaks down foodstuffs to simple components for absorption?

Digestion Process
1: The Digestion Process. Digestion converts the food we eat into smaller particles, which will be processed into energy or used as building blocks. Once you have eaten, your digestive system (Figure 2.3. 1) breaks down the food into smaller components.

What is used to break down digested food substances?

The pancreas makes enzymes that help digest proteins, fats, and carbs. It also makes a substance that neutralizes stomach acid. These enzymes and bile travel through special pathways (called ducts) into the small intestine, where they help to break down food.

Is required to break down food in the body?

Why is digestion important? Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.

What removes waste from the body?

Excretion is the process of removing wastes and excess water from the body. It is one of the major ways the body maintains homeostasis. Organs of excretion make up the excretory system. They include the kidneys, large intestine, liver, skin, and lungs.

What is gut in human body?

The gut (gastrointestinal tract) is the long tube that starts at the mouth and ends at the back passage (anus).

What are the six processes of digestion?

The six major activities of the digestive system are ingestion, propulsion, mechanical breakdown, chemical digestion, absorption, and elimination. First, food is ingested, chewed, and swallowed. Next, muscular contractions propel it through the alimentary canal and physically break it down into tiny particles.

What are the 5 steps of digestion?

Figure 2: The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation. Some chemical digestion occurs in the mouth.

What enzyme digests fat?

Lipase – pronounced “lie-pace” – this enzyme breaks down fats.

Which is the largest gland in the human body?


  • Liver, the largest gland in the body, a spongy mass of wedge-shaped lobes that has many metabolic and secretory functions.
  • Liver tissue consists of a mass of cells tunneled through with bile ducts and blood vessels.
