Human Body Systems

All living things are made of cells.  Animals, plants, and humans are made up of cells working together at different levels to perform specific functions.

Put the following levels of cellular organization in order from

SMALLEST to LARGEST.

• Cell - Tissue - Organ - Organ System - Organism

• Tissue – Organ – Cell - Organ System - Organism

• Cell – Tissue - Organ System – Organ - Organism

• Organism - Organ System – Organ – Tissue – Cell

Which of the following provides the best example of the PARTS of a SYSTEM working together to achieve a specific function?

• Animals that prey on other animals require the ability to move about their environment.

• Red blood cells are capable of transporting oxygen because of their chemical composition.

• Specialized cells in a plant's leaf open and close in response to changing conditions.

• Glands in the mouth, the stomach, the pancreas, and the small intestine secrete chemicals that break down nutrients.

Which best states how the parts of the digestive and circulatory systems interact to allow this to occur?

• Nutrients from food are broken down inside the blood vessels of the body & then transported to the intestines to be absorbed.

• Nutrients from food are absorbed by blood vessels in the body & then transported to the intestines to be broken down.

• Nutrients from food enter the intestines & are absorbed by blood vessels that transport them to other parts of the body.

• Nutrients from food enter the intestines & are absorbed by blood vessels that then transport them to the pancreas for further digestion.

   

Match the organ system with the function that they perform.

Voluntary and involuntary movements guide the food through the process of digestion.

• nervous system

• muscular system

• circulatory system

• digestive system

Match the organ system with the function that they perform.

Oxygen is brought in to the body in order to pair it with glucose to create ATP.

• respiratory system

• circulatory system

• nervous system

• muscular system

Match the organ system with the function that they perform.

Electric impulses make muscles move in order to eat.

• digestive system

• nervous system

• muscular system

• respiratory system

Match the organ system with the function that they perform.

Nutrients are transported through a network running throughout the body.

• digestive system

• muscular system

• circulatory system

• nervous system

Match the organ system with the function that they perform.

Nutrients are taken from food.

• nervous system

• digestive system

• circulatory system

• muscular system

Which of the following best describes the way all other systems of the body depend on the digestive system?

• The digestive system provides the energy for the operation of all other systems

• The digestive system removes the wastes that would contaminate the other systems.

• The digestive system makes the food the body needs in order to live.

• The digestive system creates the cells that make up the rest of the body.

Which of the following best describes an example of a message received by the nervous system that resulted in an immediate behavior?

• Chris listened to his friend sing his favorite song.

• Danny noticed the smell of his friend's new perfume.

• Tom read a book his father had given him on his birthday.

• James ducked when he saw a baseball flying at him.
