APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The digestive system stores and digests foods, transfers nutrients to the body, eliminates waste and absorbs water. Digestive processes provide the building blocks for some neurotransmitters. The autonomic nervous system controls the tone of the digestive tract. The brain controls drinking and feeding behavior.

Detailed explanation-2: -The large, hollow organs of the digestive tract contain a layer of muscle that enables their walls to move. The movement of organ walls can propel food and liquid through the system and also can mix the contents within each organ. Food moves from one organ to the next through muscle action called peristalsis.

Detailed explanation-3: -The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles.

Detailed explanation-4: -The motor neurons release a chemical, which is picked up by the muscle fibre. This tells the muscle fibre to contract, which makes the muscles move. Neurons carry messages from the brain via the spinal cord. These messages are carried to the muscles which tell the muscle fibre to contract, which makes the muscles move.

Detailed explanation-5: -When we eat, our brain sends signals to our digestive tract so that it can break down what we eat into smaller molecules for absorption into our bloodstream. The nervous system controls the digestive system by sending signals to the brain and organs.
