What does the body do with Carbon Dioxide and Water waste from respiration?

• nothing

• gets rid of it through lungs, sometimes skin, Ears...

• uses for energy

Why do living things do cellular respiration?

• why not?

• to convert sunlight energy and small molecules to glucose

• to convert glucose (sugar) to ATP so cells can use it.

What are the two reactants (starting compounds) of cellular respiration?

• Carbon Dioxide and Water and ATP

• Oxygen and Glucose

• nitrogen and Phosphorous

What are the products of cellular respiration?

• Carbon Dioxide and Water and ATP

• Oxygen and Glucose

• people and plants

What body systems provide mammals like humans with Oxygen and Glucose?

• Endocrine and reproductive

• Nervous and Muscular

• Respiratory and Circulatory

Describe how Oxygen passes from the air into the blood

• Enter enters through the nose or mouth, trachea,then passes through: bronchi, (in lungs)--> bronchioles, alveoli, capillaries onto red blood cells inside.

• mouth, esophagus, stomach, intestine, rectum, anus

• Bonees, tendons, muscles

Which are major circulatory organs?

• ovaries, testicles, uterus, urethra

• organelles, cells, tissues, organs, organ systems, organisms

• heart, blood vessels, blood

What is the role of the respiratory system?

• To react to stimuli

• to circulate materials around the body

• to tranfer oxygen into the blood and remove Carbon Dioxide

Which of these are passageways that air can flow through in the respiratory system?

• Pharynx

• trachea

• bronchi/ bronchioles

• diaphragm

These sacs expand to fill with and hold air. They also get smaller so that CO2 can me expelled.

• diaphragm

• alveoli

• lungs
