22
Q

Capillary beds and alveoli

A

Surround to help with gas exchange

23
Q

Visceral pleura

A

Single layer of cells that surrounds alveoli

24
Q

Partital pleura

A

Stuck on surface of diaphram

25
Q

Septal cells

A

Produce serphactin that mixes with water to increase surface area so lungs dont collapse

26
Q

Type I alveloi cells

A

Make up alvoli

27
Q

External resporation

A

Pulmonary ventilation, gas exchange at level of avelou and gas transport with oxy binding to hemoglobin

28
Q

Internal gas exchange

A

At level of capillaries and tissue

29
Q

Inspiration

A

Ribs move up and out, diaphram drops pulling praital membrane and visceral membrane widening alveoli creates vaccum air come in

30
Q

Exhalation

A

Ribs in and down, diaphram goes up pressure rises air flows out

31
Q

Inhalation graph

A

Pressure drops one causing air to flow in intrapleural pressure drops tital volume increases 500

32
Q

Exhalation graph

A

Pressure rises back up pressure goes back up 500ml out

33
Q

Sirus fluid

A

Sticks membranes together

34
Q

Must have negative pressure in pleural space

A

So lung doesnt collapse

35
Q

Resting tital volume

A

500ml

36
Q

Residual volume

A

Air you can never push out

37
Q

Expiratory reserve volume

A

Ab muscles used to push all air out

38
Q

Insipratory reserve volume

A

All air in

39
Q

Vital capacity

A

IRV+ERV+tital volume

40
Q

Gas exchange in pulmonary capillary

A

Gradients to exchange O2 from alveolus to blood and CO2 out of blood

41
Q

Po2 in blood in pulmonary cap

A

40

42
Q

Pco2 in blood in pulmonary cap

A

45

43
Q

Po2 in alveolus

A

100

44
Q

Pco2 in alveolus

A

40

45
Q

Po2 in blood in systemic cap

A

100

46
Q

Pco2 in blood in systemic cap

A

40

47
Q

Pco2 in tissue

A

45

48
Q

Po2 in tissue

A

40

49
Q

Oxygen hemoglobin saturation curve

A

In lungs heme is 100% saturated by oxy and as you move toward tissue it drops because unloading oxy to tissue

50
Q

Coolerativity

A

As o2 bind hem flexes and it makes binding effieity or the rest go up making it easy to bind

51
Q

Things cause right shift

A

Increase CO2, proton, temp, 23 BPG

52
Q

Left shift

A

Stonger binding for O2

53
Q

Tissue cell gas exchange

A

Dissolve CO2 causes HbCO2 and the bhor effect to push bicarbonate buffer to create more proton causes oxy to unload

54
Q

Pulmonary cap gas exchange

A

CO2 goes to alveoli and O2 comes in HbH causes more proton that shifts bicarbonate buffer left to produce CO2 and water
