Respiration: Gas exchange

Respiration: Gas exchange

Cellular Respiration

• Respiration is the release of energy in your cells using Oxygen and Glucose

• Carbon dioxide is a waste product

• Oxygen and Carbon dioxide are exchanged in your Alveoli

• Alveoli are in your lungs - around 300 million

• Alveoli are surrounded by tiny blood vessels called capillaries

Multiple Choice

What is a waste product of respiration?

• Oxygen

• Glucose

• Carbon Dioxide

Multiple Choice

What are the two gases exchanged in cellular respiration?

• 02 & CO2

• O2 & H2

• CO2 & H2

Multiple Choice

What are the tiny air sacs in your lungs called?

• Ravioli

• Balloons

• Alveoli

Multiple Choice

What surrounds the alveoli?

• lungs

• Capillaries

• Blood

Cellular Respiration:

• The movement of gases from one area to another is called diffusion

• Particles move from an area of high concentration to an area of low concentration

• The gases diffuse through the membrane of the alveoli

• Oxygen diffuses into the blood stream and Carbon dioxide diffuses into the alveoli

• The circulatory system carries Oxygen all around your body and delivers Carbon dioxide to your lungs

Multiple Choice

Does Oxygen diffuse...

• Into the lungs

• Into the blood stream

Multiple Choice

Does Carbon dioxide diffuse....

• Into the lungs

• Into the Blood stream

Multiple Choice

Do gas particles move from......

• An area of high concentration to an area of low concentration

• An area of low concentration to an area of high concentration

Multiple Choice

What is the movement of gases called?

• Destruction

• Diffusion

• Distillation

Multiple Choice

Which system carried the gases around your body?

• Circulatory system

• Digestive System

• Skeletal System
