What isDyspnea?

A

difficult or labored breathing

29
Q

What are secondary effects of COPD

A

high blood pressure, heart disease

30
Q

How does smoking impact respiratory effiency?

A

-nicotine vaos-constricts, carbon monoixde binds hemoglon, ………

31
Q

What is the effect of nicotine on the airway?

A

It is a vasoconstrictor

32

Lung cancer ( by smoaking

A

bronchial epithelium into stratified squamous

38
Q

Describes the origin and pathology of small cell (oat cell carcinoma

A

The originate in the primary bronchi

39
Q

What is the conducting division respiratory system?

A

The “pipes” nostrils, pharynx, trachea, bronchi, bronchioles, including terminal bronchioles

40
Q

What are two cartilage areas of the nose?

A

The septal cartilage and the alar cartilage

41
Q

What are the macrophages of the lungs called?

A

Alveloar dust cells

42
Q

What is Dalton’s law?

A

Partial prssures….

43
Q

People (probably all land animals) are _____ pressure breathers. This means that we ____ the volume of our lungs in order to ____ the pressure to draw air in.

A

Negative pressure breathers. Increase the volume, to lower the pressure .

44
Q

What is Charle’s law? How does it relate to breathing?

A

if you heat a gas under constant pressure the volume will expand. Warm the air in the body help the volume expand more

45
Q

Dalton’s Law

A

The partial pressure of each gas equals to total pressures or 1 atm

46
Q

Henri’s law

A

The amount of a gas going into the blood depends on its soluabillity

47
Q

What part of respiration typically does muscular work?

A

Inhalation

48
Q

What cause exhalation to occur without muscular work

A

Surface tension of water colapsing alveoli and pulling thoracic cavity in with the lungs

49
Q

What is a pneumothorax? What is the effect on respiration and by what mechanism?

A

A pneumothorax is additional air in the pleural cavity, often a wound, but they can be spontaneous. The cause lung to collapse because the intrapleural pressure is now equal to or greater than the pressure in the lungs.

50
Q

What is compliance of the lung?

A

The elasticity of the lung

51
Q

What is the valsalva maneuver?

A

Holding air in you lungs to add pressure to help with abdominal work

52
Q

What is the Dorsal respiratory group?

A

Part of the medulla that control baseline respiration. As called the inspiratory area

53
Q

What does the ventral respiratory do?

A

Controls the muscles for forced exhalation. The internal intercostals and the abdominal muscles

54
Q

What do the Pneumotaxic and apneustic areas do?

A

Pneumatic increases respiration. Apneustic is decreased breathing during deep sleep. They are also called the pontine respiratory group

55
Q

Where is pH monitored in the body ? Are the differences at the different locations?

A

In the medulla, caratoid sinuses, and the aortic arch. The medulla measure CSF and primarily measures protons and secondarily CO2. The arteries measure blood, the measure C02 primarily and protons secondarily.

56
Q

What is hypercapnea?

A

too high partial pressure of CO2.
