Anatomy

Front 1

organs forming respiratory pathway

Back 1

nose, pharynx, larynx, trachea, bronchi, lungs, alveoli,

Front 2

how does the respiratory system protect itself

Back 2

cilia (tiny hairs/muscles in nose)
mucous traps unwanted particles,

Front 3

necessity of cilia in trachea

Back 3

traps bacteria and viruses --> mucous

Front 4

structure and function of lungs

Back 4

exchange of oxygen,
necessary for cellular process, carbon dioxide and cellular waste

Front 5

function of pleural coverings

Back 5

provides lubricated surfaces of the chest and lungs to contract with minimal friction during respiration

Front 6

function of respiratory membrane

Back 6

barrier where gases are exchanged between alveolar air and blood
prevents alveolus from collapsing as air moves in n out during respiartion

Front 7

how is a lung organized

Back 7

occupy entire thoracic cavity except mediastinum, divided into lobes by fissures, left 2, right 3

Front 8

mechanics of inspiration and experation
breathing in n out

Back 8

inhale: diaphragm expands chest cavity, muscles move outwards, size decreases air pressure so air rushes in to equalize pressure
exhale: diaphragm relaxes and returns to resting position, reduces size of thoracic cavity increasing pressure and forcing air out of lungs

Front 9

describe alimentary canal

Back 9

gastrointestinal tract digests food and absorbs fragments through its lining in blood
its continuous, coiled, hollow, muscular tube through ventral body

Front 10

digestion

Back 10

movements of food and liquid
lubricates food
breaks down carbohydrates, fats, proteins and reabsorbs nutrients

Front 11

absorption

Back 11

process of absorbing substances into cells or across tissues and organs through diffusion and osmosis

Front 12

ingestion

Back 12

take into body by swallowing or absorption

Front 13

mechanical digestion

Back 13

when food is physically broken down

Front 14

chemical digestion

Back 14

chemical break down of foods
proteins--> amino acids
cards--> simple sugars
fats--> fatty acids

Front 15

propulsion

Back 15

process that moves food through alimentary canal
(swallowing)

Front 16

absorption

Back 16

transport of end products to the blood or lmph

Front 17

defecation

Back 17

elimination of indegestible substances from the body

Front 18

peristalsis

Back 18

waves of contraction and relaxation of muscles in organ walls
(squeezes food along pathway)
