Respiratory and Circulatory Systems

LT #1: Ribs expand, diaphragm moves down, lungs inflate. What is happening?

• Inhale

• Exhale

LT #1: Ribs move inward, diaphragm moves up, lungs deflate. What is happening?

• Inhale

• Exhale

LT #1: Which organ system SUPPLIES the blood with O2?

• Circulatory

• Respiratory

LT #1: Which organ system REMOVES CO₂ from the blood to be exhaled?

• Respiratory

• Circulatory

LT # 2: What is #3 pointing to?

• Larynx

• Pharynx

• Trachea

• Diaphragm

LT #2: What is #4 pointing to?

• Diaphragm

• Lung

• Trachea

• Alveoli

LT #2: What is #6 pointing to?

• Lung

• Diaphragm

• Larynx

• Pharynx

LT #2: What is this structure?

• Bronchi

• Alveoli

• Larynx

• Trachea

LT #3: Which part of our respiratory system exchanges O₂ for CO₂ and is covered in a tiny blood vessel called capillaries?

• Alveoli

• Larynx

• Trachea

• Nasal Cavity

LT #3: Which respiratory gas flows INTO the nasal cavity past the pharynx then larynx, down the trachea, passed a tube of the bronchi and eventually into the alveoli to be carried on a red blood cell in the capillaries?

• O₂

• CO₂
