Human Body Systems Review

The main function of the muscular system is-

• support of the body
• removal of waste
• break down of food
• movement of the body

The cell wall is most like which organ system?

• nervous
• respiratory
• excretory
• integumentary

Which organ system is responsible for transporting oxygen throughout the organism?

• excretory system
• endocrine system
• respiratory system
• circulatory system

When your body needs additional energy, like when you run, things happen in your body systems to give you the additional food and oxygen you need in your cells. Which of the following is happening to send more energy to cells when your running?
I. Your skeletal system gets stronger. 
II. Your digestive system breaks down food faster.
III. Your heart pumps blood with more force.
IV. Your lungs work harder and faster.

• I and III
• I and II
• III and IV
• II and IV

Based on the functions in the table, which system is the skeletal system?

• system w
• system x
• system y
• system z

Describe the function of the body system shown above in the diagram.

• The nervous system senses the environment and controls the body.
• The skeletal system controls nerves.

In addition to other materials, both the respiratory system and the circulatory system move oxygen. Which of the following BEST explains why there are two human body system to move oxygen?

• One moves oxygen into the body, and the other moves oxygen out of the body.
• One moves oxygen while awake, and the other moves oxygen when asleep.
• One moves oxygen into the body, and the other moves oxygen through the body.
• One moves oxygen to the upper body, and the other moves oxygen to the lower body.

Organelle
Nucleus- Contain genetic information and make decisions for cell.
Mitochondria-Energy production.
Lysosome- Break down waste and remove from cell.
Cytoplasm-Substance allowing organelles to move throughout cell.
Cell Membrane-Passage of materials in and out of cell, protection.
Body System
Excretory-Storage and removal of waste.
Digestive-Break down food and absorb nutrients for energy.
Nervous-Sense outside world and send signals throughout body.
Integumentary-Provide protection from outside environment.
Circulatory-Transport materials.

• Endocrine system
• Skeletal system
• Immune system
•  Muscular system

The heart is part of the circulatory system. Which of the following is the correct classification?

• Heart:Circulatory System::Tissue:Organ
• Heart:Circulatory System::Tissue:Organ System
• Heart:Circulatory System::Organ:Organ System
• Heart:Circulatory System::Organ System:Tissue

The heart muscle in a person's chest contracts rhythmically to force blood through the circulatory system. Blood is carried away from the heart, toward the body, and then is returned to the heart.
Describe how gravity can both help and hinder the flow of blood through the body.

• Gravity can help pull blood downward from  the head toward the heart or from the heart toward the legs.
• Gravity cannot help pull blood downward from  the head toward the heart or from the heart toward the legs.
