Parts and function of the respiratory system How the respiratory system works

Short and long term effects of exercise on the respiratory system

TARGET GRADE: CURRENT GRADE:

2

BOOKLET OBJECTIVES

Develop knowledge and understanding of the structure of the respiratory system.

Understand how the lungs inhale and exhale. Understand where and how gaseous exchange occurs. Develop knowledge and understanding of how exercise

effects our respiratory system, both in the short and long term.

Learn in detail about the two types of respiration that create energy within the human body, AEROBIC and ANAEROBIC.

The Path of Oxygen entering the Body

Complete the sentences below using the words from the box above:

1) Oxygen enters the body through the ___________ and

__________.

2) When oxygen goes in through the nose, it passes through the

nasal cavity where __________ and small __________ help

stop dirt and pollen in the air from entering the body.

3) Oxygen then passes through the ___________ and then down

the ____________ in the lungs.

4) Oxygen then enters both the left and right lungs through two

_____________.

5) These Bronchi then splint into much smaller _______________

which transports the oxygen to the ______________. This is

where oxygen is passed into the blood stream and carbon

dioxide is taken out.

Mouth Trachea Alveoli Nose

Mucus Hairs Larynx

Bronchi Bronchioles
