Involuntary activities throughout the body are primarily controlled by the autonomic nervous system. This system regulates functions like heart rate, digestion, and respiratory rate without conscious effort.
The primary organs associated with digestion are the mouth, stomach, small intestine, and large intestine. These organs work together to break down food, absorb nutrients, and eliminate waste from the body.
Actions controlled by the autonomic nervous system, such as heartbeat and digestion, are not under conscious control by the brain. Reflex actions, like pulling your hand away from a hot surface, are also not controlled by the brain but instead by the spinal cord.
The pyloric valve, also known as the pyloric sphincter, is located at the junction between the stomach and the small intestine. Its primary function is to regulate the passage of partially digested food (chyme) from the stomach into the duodenum, the first part of the small intestine. The valve opens to allow small amounts of chyme to enter the small intestine for further digestion and nutrient absorption, while preventing backflow into the stomach. This process ensures that food is released in a controlled manner for optimal digestion.
Fats do not undergo any significant chemical digestion in the stomach. While enzymes like gastric lipase are present, the primary digestion of fats occurs in the small intestine with the help of bile and pancreatic enzymes. The stomach mainly serves to mechanically break down food and mix it with gastric juices, while chemical digestion of carbohydrates and proteins begins there.
The primary site of intracellular digestion are the lysosomes.
Digestion is controlled by the parasympathetic division of the autonomic nervous system.

The primary function of the pancreas is to produce chemicals that are crucial to proper digestion and blood sugar regulation.
Chemical digestion occurs through out the digestive tract with the possible exception of the esophagus. It is regulated by enzymes that help speed it up.
