24
Q

What is tachycardia?

A

Increased heart rate for a variety of reasons

25
Q

What is arrhythmia?

A

Condition where the heartbeat is a regular

26
Q

What does the P-wave represent?

A

Represents the depolarization of both atria 

27
Q

What does the QRS complex represent?

A

Combination showing ventricle depolarization

28
Q

What does the t wave represent?

A

Represents the repolarization of both ventricles

29
Q

Systemic loop

A

Oxygenated blood is pumped from the left ventricle to the aorta and beyond 

30
Q

What is the larynx

A

The Voice box and sits superior to the trachea

31
Q

Alveoli

A

Thin air sack that are wrapped in capillaries or gas exchange occurs 

32
Q

Diaphragm

A

Don’t shave the muscle that moves upward during inspiration and downward during expiration

33
Q

Why do the rings of cartilage cover the front 2/3 of the trachea

A

To allow for the movement of food through the esophagus

34
Q

Where are the lungs housed?

A

Thoracic cavity

35
Q

Where are the lungs housed?

A

Thoracic cavity

36
Q

What is the movement of molecules from an area of high concentration to an area of low concentration?

A

Diffusion 

37
Q

Abnormal self growth can block airways leading to shortness of breath

A

Lung cancer

38
Q

Leads to irritation and buildup of mucus in the lungs

A

Common cold

39
Q

Tissue gets thick and stiff, scarring the lungs, and preventing gas exchange

A

Pulmonary fibrosis

40
Q

Airways become inflamed and narrowed muscles tighten, and wheezing is often observed

A

Asthma

41
Q

Air collects in the spaces between lung tissue layers, pressure built-up prevents lung expansion

A

Punctured lung

42
Q

Step one

A

The intercostals lift the rib cage and the diaphragm lowers decreasing the pressure inside the long

43
Q

Step two 

A

Oxygen enters the upper respiratory tract moves through the bronchi, and then the bronchioles

44
Q

Step three

A

Oxygen enters the alveoli and passes into the bloodstream through capillaries

45
Q

Step four

A

Carbon dioxide moves from the bloodstream into the alveoli through capillaries

46
Q

Step five

A

Carbon dioxide moves from the lower respiratory tract into the upper respiratory tract and then exits the body 

47
Q

Symptoms of asthma

A

Wheezing
Shortness of breath
Chest tightness
Coughing

48
Q

What does a low pulse ox levels mean?

A

Less oxygen is being distributed to tissues

49
Q

What does the FEV rates referred to

A

Forcible inhalation volume of air during a respiration cycle

50
Q

Title volume

A

Volume of air from a maximum inhalation, followed by a maximum exhalation
