Respiration/Breathing

Question 1

What is respiration

Answer 1

Respiration is the physical process by which we take in air from the environment and release carbon dioxide with the help of a series of organs

Question 2

What is the respiration system function

Answer 2

It is responsible for breathing and gas exchange. It involves oxygen being transported and absorbed and carbon dioxide being released (waste product)

Question 3

What is aerobic respiration?

Answer 3

Aerobic respiration is a process that occurs in the presence of oxygen. It involves breaking down glucose molecules to produce energy, carbon dioxide, and water.

Question 4

What is anaerobic respiration?

Answer 4

Anaerobic respiration is a process that occurs in the absence of oxygen. It involves breaking down glucose molecules to produce energy and other byproducts such as lactic acid or ethanol

Question 5

What organ do your mouth and nose both connect to

Answer 5

The Trachea

Question 6

What is the function of the rings of cartilage

Answer 6

They keep the trachea from collapsing

Question 7

_________1_________ diffuses into the blood capillary from the alveoli and _________2__________ diffuses out of the capillary into the air sac

Answer 7

1 = Oxygen
2 = Carbon Dioxide

Question 8

Where does diffusion of gases occur?

Answer 8

Air Sacs / Alveoli

Question 9

What is diffusion?

Answer 9

Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration.

Question 10

When you breath in, the intercostal muscles _______________________

Answer 10

contract

Question 11

Desccribe what happens when the muscles contract

Answer 11

The intercostal muscles contract and move the ribs upwards and outwards. This increases the size of the chest and decreases the air pressure inside it which sucks air into the lungs.

Question 12

Where is energy released?

Answer 12

The Mitochondria

Question 13

Word equation for aerobic respiration

Answer 13

glucose + oxygen → carbon dioxide + water

Question 14

What is the function of red blood cells

Answer 14

They transport oxygen to different parts of the body

Question 15

What is the function of white blood cells

Answer 15

To help us fight against diseases

Question 16

What is the function of plasma

Answer 16

transport blood cells , nutrients and carbon dioxide

Question 17

What is the function of the nasal cavity

Answer 17

Warms and humidifies the air

Question 18

Function of the trachea

Answer 18

Connects the windpipe to the bronchioles

Question 19

Where does gas exchange occur

Answer 19

Air Sac/ Alveoli

Question 20

When the diaphragm moves down it causes the expansion of ribcage which also creates the expansion of the lungs. Due to this air enters the lungs

What is the name of this process?

Answer 20

. This whole process is called as inhalation or inspiration.

Question 21

When the diaphragm moves contraction of ribcage takes place which also contracts lungs and air moves out.

What is the name of this process?

Answer 21

This process is called as exhalation or expiration.

Question 22

How do fish breathe?

Answer 22

They use their gills

Question 23

How do amphibians breathe?

Answer 23

Amphibians breathe through their lungs and skin

Question 24

How do plants breathe?

Answer 24

Root hair cells help roots to “breathe”
Epidermis helps stem to breathe
Stomata helps leaves to breathe

Question 25

Where does respiration take place?

Answer 25

Mitochondria

Question 26

Thin walled balloon like structures present in the lungs are known as:

Answer 26

Alveoli / Air sac

Question 27

Word equation for anaerobic respiration

Answer 27

Glucose → Lactic acid (or Ethanol + Carbon dioxide)

Question 28

Glucose can provide instant energy because:

Answer 28

Glucose is a simple sugar that is easily broken down and utilized by cells to release energy.

Question 29

What is pulse rate

Answer 29

Number of heart beats per minute
