Respiratory system

Question 1

aerobic cellular respiration

Answer 1

produce energy from food when oxygen is there
produces carbon dioxide

Question 2

Homeostasis

Answer 2

gets rid of CO2
maintains internal balance or stability in the body

Question 3

Inhale

Answer 3

diaphragm moves down
ribs move out (chest bigger)
provides air

Question 4

Exhale

Answer 4

diaphragm moves up
ribs pull in (smaller chest)
releases air

Question 5

Purpose of respiratory system

Answer 5

gets oxygen to our blood for easy transport

Question 6

Nostrils

Answer 6

holes in nose
filter and warm incoming
air

Question 7

Pharynx

Answer 7

open space
connects nose to mouth

Question 8

Larynx

Answer 8

voice box
makes sound

Question 9

Epiglottis

Answer 9

flap in throat
covers trachea when swallowing

Question 10

Trachea

Answer 10

windpipe
carries air to lungs

Question 11

Bronchi

Answer 11

mucus & cilia which filter air
carry air to each lung

Question 12

Bronchioles

Answer 12

carry air deep into the lungs

Question 13

Alveoli

Answer 13

thin-walled sacs
exchange O2 & CO2

Question 14

Diaphragm

Answer 14

muscle under lungs
controls breathing by moving up and down

Question 15

Pleura

Answer 15

creates vacuum seal around lungs

Question 16

Visceral Pleura

Answer 16

surrounds the lungs

Question 17

Parietal Pleura

Answer 17

between the visceral pleura and rib cage

Question 18

Protection

Answer 18

Mucus: sticky layer trapping invaders
Cilia: tiny hair sweeping away trapped invaders
Outcome: invaders are let our by coughing and sneezing

Question 19

Boyle’s Gas Law

Answer 19

pressure and volume are inversely related -when one goes up, the other goes down

Question 20

Internal respiration

Answer 20

gas exchange between blood and tissues
important for cellular respiration
takes place in mitochondria
produces energy (ATP) needed for cellular activities

Question 21

Passive transport

Answer 21

movement of materials without using energy
high to low concentration

Question 22

Diffusion

Answer 22

movement of materials from high to low concentration
important for the distribution of substances

Question 23

Facilitated diffusion

Answer 23

movement of materials from high to low concentration with the help of special proteins

Question 24

Osmosis

Answer 24

movement of water molecules from low to high concentration
important for maintaining hydration and balance in cells
