Name the primary organs associated with digestion?

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.


Involuntary activities carried out throughout the body are the primary responsibility of the?

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.


What kinds of actions are not controlled by the brain?

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.


What does the pyloric valve do to let food go from the throat?

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.


Digestion respiration and other involuntary functions are under the control of the?

Digestion, respiration, and other involuntary functions are primarily controlled by the autonomic nervous system. This system regulates processes that occur automatically, such as heart rate, breathing, and digestion, without our conscious effort. The autonomic nervous system consists of two main branches: the sympathetic and parasympathetic nervous systems, which work together to maintain the body's internal balance.
