1). Viceral= lines the organs 2). Parietal= lines the body cavity & secrete water

What is the visceral pleura membrane connected to?
It creates a sealed cavity with the Parietal pleura membrane and it connected tot he diaphragm
4 of 24
What happens to the diaphragm during inhalation?
The diaphragm contracts, this pulls down the lungs and increases the thoracic volume as the visceral pleura membrane is attached to the diaphragm.
5 of 24
What are the stages of inspiration?
1). Diaphragm contracts 2). External Intercostal muscles contract 3).inc in vol of thoracic cavity 4). Inc in volume= dec in pressure 5). Air is inhaled
6 of 24
What are the stages of expiration?
1). Diaphragm relaxes 2).External intercostal muscles relax 3). Decrease in vol of the thoracic cavity 4). Dec in vol= inc in pressure 5). Air is exhaled
7 of 24
What happens during exercise?
1). The diaphragm contracts more forcefully 2). More muscles involved 3). greater increase in lung volume 4). great production of lactic acid due to anaerobic respiration 5). stroke volume increases
8 of 24
Where does gas exchange occur?
In the Alveoli. O2 from alveoli to capillaries and CO2 from capillaries to alveoli
9 of 24
What affects gas exchange?
1). Thickness of the membrane 2). The concentration gradient 3). Surface area of the membrane
10 of 24
What are the two types of respiration?
Anaerobic and aerobic respiration
11 of 24
What is anaerobic respiration?
Does not require Oxygen. Created lactic acid, causing cramp
12 of 24
What is aerobic respiration?
Requires Oxygen to make energy in the form of ATP. Creates CO2 as a waste product
13 of 24
What is Glycolysis?
It is the breaking down of Glucose that occurs in the Cytoplasm and Mitochondria.
Secretes a lubricating fluid- holds pleura membranes together via surface tension

Give 2 characteristics of a birds respiratory system
1). Do not have a diaphragm 2). have 9 large air sacs- continuous flow of O2
19 of 24
Give 2 characteristics of an amphibians respiratory system
1). Do not have a diaphragm 2). semi-permeable skin- diffusion of gases
20 of 24
Give 2 characteristics of a reptiles respiratory system
1). Does not have a diaphragm 2).Exhalation and Inhalation are dependant on the expansion of the rib cage
21 of 24
Give 2 characteristics of a fish' respiratory system
1). Rows of gill filaments inside the gill arches 2). Gill filaments have a large SA, water passes over the gill filaments are gas exchange occurs via diffusion
22 of 24
Give 2 characteristics of a crocodilians respiratory system
1). They have diaphragms 2). They have a trachea
23 of 24
Give characteristics of an invertebrates respiratory system
1). They have spiracles where air enters 2).O2 is delivered directly to the tissue through tubes
