Respiratory System

Question 1

What is Cellular respiration

Answer 1

Cellular respiration is the release of energy from food. It takes place in the cells of the body

Question 2

What is external respiration

Answer 2

It is the name given to the way organisms take in oxygen for respiration and get rid of carbon dioxide and water vapour, which are the wastes from respiration.

Question 3

What is external respiration also known as

Answer 3

It is also called breathing

Question 4

What if the function of the respiratory system

Answer 4

To breathe

Question 5

What is respiration

Answer 5

It is the release of energy from food

Question 6

What can respiration use or not use

Answer 6

Oxygen can be used in respiration(aerobic respiration) and may occur without the use of oxygen(anaerobic respiration)

Question 7

What organs are involved in the respiratory system

Answer 7

The nose, trachea, bronchi(bronchus), lungs, bronchial(bronchiole), alveoli(alveolus), intercoastal muscles and the diaphragm

Question 8

What is the function of the nose

Answer 8

To take in air and filter the air with its tiny hairs

Question 9

What is the function of the trachea

Answer 9

Takes air down to the lungs

Question 10

What is the function of the bronchus

Answer 10

A tube that Carrie’s air down into the lungs

Question 11

What is the function of the lungs

Answer 11

Gaseous exchange

Question 12

What is the function of the bronchiole

Answer 12

Small tubules from the bronchus to carry air within a lung

Question 13

What is the function of the alveolus

Answer 13

Air sacs for gaseous exchange

Question 14

What is the function of the intercoastal muscles

Answer 14

Cause the chest to expand and contract

Question 15

What is the function of the diaphragm

Answer 15

Cause the volume of the chest to increase and decrease

Question 16

How many alveoli are in each lung approximately

Answer 16

300 million alveoli in each lung

Question 17

What has extremely thin walls

Answer 17

Alveoli have extremely thin walls

Question 18

How does the oxygen get into the blood stream from the alveoli

Answer 18

The oxygen in the alveoli moves through their walls and through the walls of the capillaries into the blood

Question 19

How does the carbon dioxide get to the alveoli to exit the body

Answer 19

The carbon dioxide in the blood of the capillaries moves through their walls and through the walls of the alveoli into the inside of the alveoli

Question 20

How do the nose and lungs interact with the respiratory system

Answer 20

The nose helps filter and moisten the air before it reaches the alveoli in the lungs

Question 21

How do the trachea, bronchi and bronchioles interact with the respiratory system

Answer 21

They are a system of tubes that work together to bring the air down to the lungs and up from the lungs

Question 22

How do the intercoastal muscles and the diaphragm interact with the respiratory system

Answer 22

The intercoastal muscles and the diaphragm contract at the same time to draw air into the lungs
The intercoastal muscles and the diaphragm relax at the same time to push air out of the lungs

Question 23

What does pulmonary mean

Answer 23

Something to do with the lungs

Question 24

What does the heart do

Answer 24

The heart pumps blood through the pulmonary artery to the lungs

Question 25

What is gaseous exchange?

Answer 25

It involves oxygen passing from the alveolus into the capillary and carbon dioxide and water vapor passing from the capillary into the alveolus.

Question 26

What is lime water sued for?

Answer 26

Lime water (calcium hydroxide) is used to prove that there is more carbon dioxide in exhaled air than inhaled air.

Question 27

What does exercise increase?

Answer 27

It increases the breathing rate because more oxygen is required to release energy.

Question 28

This movement of gas in the alveoli is called

Answer 28

The movement of gas is called diffusion
