In the process of deamination, the liver converts amino acids to compounds that can be used in energy metabolism. The liver removes the amino acids to produce urea. Then the urea is removed from the body as urine. During this process, the liver works in conjunction with which body system?

• endocrine

• excretory

• nervous

• respiratory

A student has strep throat. Which body system will respond to this bacterial infection first?

• muscular

• immune

• endocrine

• skeletal

Health-care workers are exposed to many different types of pathogenic and nonpathogenic microorganisms. Which body systems work together to protect the body from pathogens?

• muscular and vascular

• digestive and excretory

• circulatory and immune

• endocrine and reproductive

The human digestive system is approximately 900 cm long. Food is moved through the digestive tract primarily by

• bile produced by the pancreas

• the enzymes amylase and pepsin

• muscular contractions

• hydrochloric acid in the stomach

What two human systems work together to provide body cells with a constant supply of oxygen while removing carbon dioxide waste products?

• nervous and endocrine

• muscular and skeletal

• respiratory and circulatory

• excretory and integumentary

Which body system must directly interact for vertebrate organisms to exchange gases?

• skeletal and muscular

• excretory and reproductive

• circulatory and respiratory

• digestive and immune

The skin is the major organ in which system?

• Integumentary
• Muscular
• Endocrine
• Immune

Which two body systems are primarily responsible for gas exchange between the body and the environment?

• skeletal and muscular

• circulatory and respiratory

• circulatory and digestive

• respiratory and excretory

How do the circulatory and excretory systems work together?

• The circulatory system brings nutrients and oxygen so our cells can produce energy.

• The circulatory system brings blood to the kidneys to filter and remove waste.

• The circulatory system bring white blood cells around the body to fight infection and disease.

• The circulatory system helps the excretory system digest food.

How does the immune system depend on the circulatory system in order to function?

• The circulatory system produces antibodies used by the immune system.

• The circulatory system sends bacteria and viruses to the immune system.

• The circulatory system transports immune system cells throughout the body.

• The circulatory system protects the immune system from diseases.
