Amphibians use their skin for gas exchange. Why is it important for their skin to stay moist?

• Amphibians don't always use their skin for respiration. They also have lungs.

• Amphibians use their skin for respiration (gas exchange), and it must remain moist to absorb oxygen efficiently.

• Amphibians use oxygen for their survival. This is why the skin must stay moist.

• Amphibians only utilize water for basic survival.

Which body system is responsible for transporting oxygen and nutrients throughout the body?

• A) Nervous system

• B) Circulatory system

• C) Digestive system

• D) Skeletal system

Which organ(s) is responsible for filtering waste from the blood?

• Liver

• Kidney

• Stomach

• Heart

How do amphibians differ from reptiles? List at least two differences.

What process do amphibians go through as they change from larvae to adults?

• Transformation

• Growth Exponentially

• Metamorphosis

• Evolution

Many amphibian populations are declining worldwide. What are two major threats they face, and what can be done to help protect them?

What is the largest organ in the human body?

• Brain

• Heart

• Liver

• Skin

The muscular system helps the body move by working closely with which other system?

• Digestive System

• Circulatory System

• Respiratory System

• Skeletal System

What is the main function of the respiratory system?

• To digest food.
• To facilitate gas exchange.
• To regulate body temperature.
• To circulate blood.

The Nervous system includes the Brain, Spinal Cord, and Nerves. Our skin is also a major organ involved with the Nervous system because it allows us to feel, touch, and connect with the environment.
