Biology Quiz on Systems and Traits

When you eat food, which two systems work together to break it down and deliver nutrients to cells?

• Respiratory and nervous

• Digestive and circulatory

• Muscular and skeletal

• Immune and excretory

During exercise, your heart rate increases to:

• Remove waste faster

• Cool down the skin

• Deliver more oxygen-rich blood to muscles

• Distract you from feeling tired

The respiratory system provides oxygen that the circulatory system:

• Destroys

• Uses for bone growth

• Transports to body cells

• Stores in the stomach

Which two systems help move your body?

• Circulatory and immune

• Skeletal and muscular

• Nervous and digestive

• Respiratory and excretory

The nervous system works with the muscular system by:

• Sending electrical signals to control muscle movement

• Building muscle mass

• Delivering oxygen to the brain

• Filtering waste from muscles

If your kidneys stop working, what system is affected, and which system suffers next?

• Excretory fails, affecting respiratory

• Immune fails, affecting muscular

• Excretory fails, affecting circulatory

• Nervous fails, affecting digestive

When you are scared, your brain tells your body to prepare for danger by increasing your heart rate. This is an example of:

• Nervous system and endocrine system working separately

• Nervous system affecting the circulatory system

• Muscular system relaxing

• Digestive system speeding up

The digestive system breaks down food, and the excretory system:

• Absorbs vitamins

• Stores extra nutrients

• Removes waste left over from digestion

• Sends signals to eat more

The immune system defends the body, but needs help from the:

• Nervous system for digestion

• Circulatory system to transport white blood cells

• Skeletal system for breathing

• Muscular system for waste removal

A person breathes faster while running because the:

• Respiratory and circulatory systems are supplying more oxygen to muscles

• Nervous system is trying to slow you down

• Digestive system needs more blood

• Immune system is overheated
