Internal respiration (exchange of oxygen between blood and cells)

Question 2

Basic summary of Respiration

Answer 2

Oxygen taken in via the mouth to get to the lungs and across the walls of the lungs into the blood stream , to get to the rbc so can break down bonds to release energy

Question 3

What does oxygen do

Answer 3

Require for cell bond breakdown

Splitting molecules to release energy (ADP)

Question 4

Why are white blood cells able to attack any pathogen

Answer 4

Via changing their protein key structure which helps them to attach onto any bacteria, germ or pathogen

Question 5

What is phagocytosis

Answer 5

Process by which a cell (a phagocyte or protist) ingests another cell or particles- bacteria

Phagein = devour
Cytos = cell
Osis = process

Question 6

What is cellular respiration

Answer 6

Happens in the cell - Burning of food in O2 to process ATP (energy) and release Carbon dioxide

Question 7

Question 8

What is the lungs attached to

Answer 8

Answer 14

3
Normal - quiet
Shallow - chest breathing
Diaphragmatic- outward movement only of abdomen

Question 15

How does O2 get into cells

Answer 15

O2 dissolved into liquid around cells and passes thru cell wall onto haemoglobin in red blood cells

Question 16

What are tonsils and what are they for

Answer 16

Tonsils - collection of white blood cells first point of defence to stop pathogens entertaining the body

Question 17

What stops food going down the trachea

Answer 17

Question 18

What does the pharynx turn into

Answer 18

Trachea or esophagus

Question 19

What does the trachea split into

Answer 21

Left or right primary bronchi

Question 22

How many lobes does the left and right lungs have

Answer 22
