Human Body Systems Review

A single-cell organism can do everything a cell from a multicellular organism can do except

• specialize

• reproduce

• use energy.

• make protein.

Which two human body systems are most responsible for getting oxygen to cells?

• digestive and skeletal

• skeletal and circulatory

• circulatory and respiratory

• respiratory and digestive

• digestive

• circulatory

• respiratory

• nervous

Bone cells need nutrients. Which two systems get nutrients to bone cells?

• the digestive system and the circulatory system

• the circulatory system and the respiratory system

• the respiratory system and the skeletal system

• the skeletal system and the digestive system

There are different kinds of muscles in the human body. Each muscle is formed from a group of cells that works together. The main function of a group of muscle cells is to

• make oxygen.

• release energy.

• digest nutrients.

How are the skeletal and circulatory systems alike?

• They help give the body shape.

• They help the body make oxygen.

• They help the body remove waste.

• They help the body produce new blood.

Which best explains how the muscular system relies on the respiratory system?

• The respiratory system cools the muscular system.

• The respiratory system acts as the support system for the muscular system.

• The respiratory system brings oxygen into the body for the muscular system to use.

Which best describes the function of the skeletal system?

• It transports oxygen to cells and tissues.

• It gives shape and support to the human body.

• It takes in and breaks down all necessary nutrients for the body.
