• Integumentary 
• Nervous

Multiple Choice

Which of the following body systems work together for support, protection, and movement?

• respiratory and cardiovascular
• skeletal and muscular
• skeletal and integumentary
• digestive and respiratory

Multiple Choice

When your body comes in contact with a sharp object, an impulse sent you your brain triggers a reflex that causes you to move away from the object. What body systems are interacting to cause this response?

• Nervous, Respiratory,

• Nervous, Muscular

• Nervous, Skeletal

• Nervous, Digestive

Multiple Choice

Olympic sprinters undergo increased heart and breathing rates while competing. Which of the following best describes the interactions among systems of a sprinter?

• Respiratory system is working to obtain more oxygen, while the circulatory system works to transport the oxygen to the muscles.

• The digestive system takes in more glucose, while the excretory system removes waste.

• The endocrine system transports ATP to the nervous system

• Excretory system removes waste from the digestive system to reduce weight so the sprinter can run faster

Multiple Choice

Kidneys are part of the excretory system in a human body. They purify the impure blood and send it back to the rest of the body. Which system is mainly responsible for the transport of plasma to the kidneys?

• Respiratory system

• Circulatory system

• Muscular system

• Nervous system

Multiple Choice

Dialysis is a medical treatment used when a person’s kidneys are no longer able to function. During this process, a machine uses an artificial membrane to remove waste products from the blood. Which body system below is not functioning properly in a person who requires dialysis?

• Endocrine system
• Integumentary system
• Excretory system
• Circulatory system

Multiple Choice

What 2 systems: Absorb and deliver the digested nutrients to the cells

• Digestive and muscular

• Muscular and lymphatic

• Digestive and circulatory

• Nervous and skeletal

Multiple Choice

What 2 systems: Transports white blood cells throughout the body to fight disease

• Excretory and nervous

• Circulatory and immune

• Respiratory and nervous

• Digestive and immune

Multiple Choice

What 2 systems: Allow organs to contract and push food through

Multiple Choice

When you get cut, your skin cells release hormones that signal platelets to come and stop the bleeding. Platelets then release more hormones that signal even more platelets to help stop bleeding. The hormone signals continue until the cut is closed.

• Positive Feedback Response

• Negative Feedback Loop 

Multiple Choice

When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels. 

• Positive Feedback Response

• Negative Feedback Loop 

Multiple Choice

If the calcium in your blood decreases below homeostasis levels, a gland in the brain will sense the decrease and send a chemical message to your bones. Your bones will release calcium into the blood, bringing blood calcium levels back up. This is an example of what type of feedback?

• Positive Feedback Response

• Negative Feedback Loop

Multiple Choice

As you get dehydrated, your blood becomes thicker and harder to pump. Your kidneys will respond by stopping urine production, sending the water from urine into your bloodstream to thin your blood back to normal level. This is an example of what type of feedback?

• Positive Feedback Response

• Negative Feedback Loop
