Human Body System Interactions

Why are the lungs, the major organ of the respiratory system, also considered an excretory organ?

• They get rid of carbon dioxide, a cellular waste

• They get rid of oxygen, a cellular waste

• They get rid of urea, a cellular waste

• They get rid of salt, a cellular waste

What is the correct relationship between the digestive system and the muscular system?

• Most organs of the digestive tract are made of skeletal muscle.

• Peristalsis is controlled by smooth muscle tissue.

• The stomach has three layers of cardiac muscle tissue.

What systems do neurons depend on to be able to conduct cellular respiration (a process that has the key ingredients of oxygen and glucose)?

• excretory, digestive, circulatory

• musculoskeletal, nervous, respiratory

• nervous, excretory, digestive

• respiratory, digestive, circulatory

How do the skeletal and circulatory systems relate to each other?

• Bone marrow produces blood.

• The heart is made of cardiac muscle tissue.

• The heart is held in place in the chest by ligaments.

• The blood brings carbon dioxide and glucose to the cells of the bones.

The digestive and respiratory rely on the ___ systems to transport needed materials to the cells.

• circlatory and excretory

• circulatory and muscular

• nervous and digestive

• nervous and skeletal

How do the nervous and endocrine systems interact to regulate body functions?

• The nervous system releases hormones that regulate the endocrine glands.

• The endocrine system sends electrical signals to the nervous system.

• The nervous system uses neurotransmitters to influence hormone release.

• The endocrine system directly controls muscle contractions.

• Circulatory and excretory systems

• Muscular and skeletal systems

• Nervous and endocrine systems

What role does the circulatory system play in the interaction with the immune system?

• It transports immune cells to sites of infection.

• It produces antibodies to fight pathogens.

• It filters pathogens from the blood.

• It digests harmful bacteria.
