Anything in the external environment that the body responds to

What changes occur to the circulatory system during prolonged exercise?

Increased heart rate and improved blood flow to muscles.

Decreased heart rate and blood pressure.

Reduced oxygen delivery to the brain.

Increased blood flow to the digestive system.

How do muscles protect bones?

Muscles absorb impact and provide stability, protecting bones from stress and injury.

Muscles generate heat and promote blood flow to bones.

Muscles create a barrier that prevents bone growth.

Muscles release hormones that strengthen bones.

Anything in the external environment that the body responds to

A response to a physical change

What is a response in terms of human body systems?

A response is a question or answer.

A response is a form of communication.

A response is a statement of fact.

How does the nervous system respond to temperature changes?

The nervous system sends signals to the brain, and the brain responds to either the muscles, blood vessels, or skin

The nervous system instructs the skin to sweat in order to raise body temperature

How does the nervous system prevent muscle damage?

The nervous system constantly informs the brain of position and pressure in muscles, and the brain instructs for movement or change of posture

The nervous system does not interact with the muscles

The nervous system overrides the muscles and moves them manually

How does the skeleton protect the nervous system?

Our spine protects our spinal cord

Our phalanges protect sensory receptors

What happens to blood flow during stress?

Blood flow increases to muscles and vital organs while decreasing to non-essential areas.

Blood flow remains constant throughout the body during stress.

Blood flow decreases to all areas of the body during stress.

Blood flow is redirected solely to the brain during stress.

What triggers changes in breathing?

Increased carbon dioxide levels and decreased oxygen levels in the blood.

Increased nitrogen levels and stable oxygen levels in the blood.

High blood pressure and low heart rate changes.

Decreased carbon dioxide levels and increased oxygen levels in the lungs.

How does the nervous system control digestion?

Our muscles involuntarily contract to move food

We have increased blood flow during digestion

Our heart rate slows during digestion

What happens if nerve signals in the excretory system are disrupted?

We would have trouble holding our bladder or knowing when our bladder is full

We would not have proper hormone regulation

We would NOT be able to filter out waste products at all

How does the circulatory system respond to stress (fight-or-flight)?

Carries hormones where they need to be for increased reaction time

Sends signals to reduce movement

What could cause coordination (fluid movement) to be impaired?

Neurological disorders, injuries, muscle weakness, balance issues, and medications.

Vision problems, fatigue, dehydration, and stress.

Environmental factors, temperature changes, overexertion, and age.

Poor nutrition, lack of sleep, anxiety, and distractions.

How does the nervous system prioritize body responses?

Prioritizes responses for bodies health

How does the body return to normal after stress?

The body reducing stress hormones and promoting relaxation.

The body increases adrenaline levels to cope with stress.

The body shuts down the immune system during stress recovery.

The body relies on caffeine to regain energy after stress.

Why does your body breathe faster when your heart is beating faster?

Your body is circulating blood faster

Your muscles are using less energy

How does the blood help remove carbon dioxide from your body?

The circulatory brings carbon dioxide back to your respiratory system to be exhaled

You nervous system tells your lungs to get rid of the carbon dioxide

Why does your body send more blood to the stomach after you eat?

To speed up the digestion process

To gather nutrients efficiently

Why do your muscles need more blood when you exercise?

Because your muscles are using more oxygen than normal, therefore they need more blood to supply more oxygen

Because they are always so needy and think their system is the only one that matters

Because you need blood to raise pressure and feel the pump

What could happen if nutrients cannot enter the blood?

You would not be able to get nutrients to all parts of your body that need it

How does blood help remove waste from muscles?

Blood helps remove waste from muscles by transporting metabolic waste products to the lungs and kidneys.

Blood removes waste by absorbing it into muscle fibers.

Blood helps muscles by delivering oxygen and nutrients only.

Blood eliminates waste through direct muscle contact.

How do moving muscles help push blood back to the heart?

Moving muscles help push blood back to the heart by compressing veins and facilitating blood flow through one-way valves.

Muscles push blood by expanding arteries and increasing pressure.

Moving muscles create suction that draws blood into the heart.

Blood is pushed back to the heart through muscle contractions in the lungs.

Why does your heart beat faster when you are scared or excited?

Your heart beats faster due to adrenaline release during fear or excitement.

Your heart beats slower to conserve energy during fear.

Your heart beats faster to cool down your body temperature.

Your heart beats faster to pump more oxygen to your brain.

What is the role of bone marrow in the circulatory system?

Bone marrow produces blood cells for the circulatory system.

Bone marrow stores fat for energy production.

Bone marrow filters toxins from the blood.

Bone marrow regulates blood pressure in the body.

Why are red blood cells important for your body?

Red blood cells are important because they transport oxygen and carbon dioxide in the body.

Red blood cells protect against infections and diseases.

Red blood cells are responsible for hormone production in the body.

Red blood cells help in digestion and nutrient absorption.

What might happen if white blood cells could not move through the blood?

The immune system would fail to respond effectively to infections.

White blood cells would multiply uncontrollably in the bloodstream.

The body would become immune to all diseases instantly.

Infections would be eliminated before they occur.

Why do hormones need the circulatory system to do their job?

Hormones need the circulatory system to travel quickly and efficiently to their target cells or organs.

Hormones rely on nerve signals to reach their target cells effectively.

Hormones are absorbed directly by the tissues without needing circulation.

Hormones are only active in the area where they are produced.

How can a hormone change the activity of the heart or blood vessels?

A hormone such as adrenaline will cause a full body response that includes increase in heart rate.

Hormones can only decrease heart rate and blood flow.

Hormones have no effect on heart or blood vessel activity.

Hormones can only regulate blood sugar levels in the body.
