How does resp differ from breath

Resp is in the mitochondria in cells/ O2 + glucose= ATP & gives off co2 and h2o

Breath is in lungs/ air flowing in and out of lungs

1

List da structures air passes through to get to lungs

Nose -> nostrils -> nasal cavity -> pharynx -> larynx ->trachea -> bronchus -> secondary bronchi -> bronchioles -> alveoli

2

Three ways resp system changes sir before it gets to lungs

1. Cleaned
2. Warmed
3. Moistened

3

Gases exchanged in resp system

O2 and CO2

4

How yo inhale and exhale

Inhale - ri= up&out/ di= down/contract air pressure comes in/decreases

Exhale- ri= inward/relax di= up / relax air pressure leaves/increases

5

Voice is made in ______ when air goes over _____ ______

1. Larynx
2. Vocal chords

6

Air goes in

Ri- up & out

Di- down/contracts

7

Air goes out

Ri- inward & downward

Di- up/contracts

8

2 purposes of left over air

1. Help warm other air
2. Prevents lungs from collapsing

9

Gas that enters alveoli from rbc

Co2

10

Gas exits alveoli to rbc

O2

11

Higher to lower

Diffusion

12

Rbc delivers O2 to

Body cells

13

Gas removed from bc by rbc

Co2

14

Too much mucus is made in bronchial, restricting air flow

Chronic bronchitis

15

Mostly allergic reaction, causing bronchial tubes to constrict

Asthma

16

Smoking is main cause

Lung cancer

17

The alveoli lose elasticity and surface area

Emphysema

18

Fluid fills the lungs due to harmful bacteria or a virus

Pneumonia

19

Three things excretory systems removes

Anything else
H2O
Urea

20

Path of urine through body

Kidney
Ureter
Bladder
Urethra

21

Main organ

Kidneys

22

3 other organs

1. Lungs
2. Skin
3. Large intestines

23

Where are nephrons

Kidneys

24

Excretion?

The getting rid of waste

25

Compare and contrast ureters and urethra

Ureters- puts waste in urinary bladder
Urethra- releases water out of body

26

Urea?

Nitrogen waste

27

Urine?

Urea+ H2O+anything else excess in blood
