Question

nose to gather information about the food.

1. the brain sends messages through ______ neurons to control movement.
2. the ______ system provides bones and joints that allow the body to move and stay supported.
3. muscles in the arm and hand belong to the ______ system.
4. the muscles in the ______, tongue, and jaw help break food into smaller pieces.
5. the automatic wave - like squeezing that moves food through the digestive system is called ______.
6. digestion begins in the ______, where teeth and saliva mechanically and chemically break down food.
7. the ______ mixes food with acids and enzymes to continue digestion.
8. the ______ intestine is the main site of nutrient absorption.
9. the ______ system transports nutrients and oxygen throughout the body.

write numbers 1 - 5 to show the order in which the systems play their main roles in seeing, picking up, and eating food.

1. ____ circulatory system

____ muscular system
____ digestive system
____ nervous system
____ skeletal system

1. why does swallowing become automatic after it starts?

____

Explanation:

For question 2: Motor neurons transmit signals from the brain to muscles for movement control.
For question 3: The skeletal system consists of bones and joints, providing support and movement.
For question 4: Muscles (including those in arm/hand) are part of the muscular system.
For question 5: Muscles in the cheeks (along with tongue, jaw) help chew food.
For question 6: Peristalsis is the wave - like muscle contraction moving food in the digestive tract.
For question 7: Digestion starts in the mouth with teeth (mechanical) and saliva (chemical) breakdown.
For question 8: The stomach mixes food with gastric juices (acids, enzymes) for digestion.
For question 9: The small intestine is the main site for nutrient absorption (not large as initially written; large intestine absorbs water etc.).
For question 10: The circulatory system (heart, blood vessels) transports nutrients and oxygen.
For question 11: Order for seeing, picking, eating: 1. Nervous (process vision, initiate actions), 2. Skeletal (support movement), 3. Muscular (movement to pick/eat), 4. Digestive (process food), 5. Circulatory (transport nutrients). So correct order: Circulatory - 5, Muscular - 3, Digestive - 4, Nervous - 1, Skeletal - 2.
For the last question: Swallowing becomes automatic due to peristalsis (involuntary muscle contractions in esophagus) after initiation, moving food to stomach without conscious control.

Answer:

1. motor
2. skeletal
3. muscular
4. cheeks
5. peristalsis
6. mouth
7. stomach
8. small
9. circulatory
10. 5 Circulatory System; 3 Muscular System; 4 Digestive System; 1 Nervous System; 2 Skeletal System

Last question: Swallowing becomes automatic because of peristalsis (involuntary muscle contractions in the esophagus) that moves food to the stomach without the need for conscious control after it starts.
