CAK enig?

22
Q

Altitude of a person smoking 20 cigarettes a day?

A

4000-5000. and have a raised carboxyheamoglobin level by about 7%

23
Q

What is hypertension?

A

High bloodpressure.

Reducerer hjerte frakvensen og udvider blodårerne(vasodilation)

24
Q

What is hypotension?

A

Low bloodpressure.

Hjerte frekvensen skal sættes op og blodårerne trækker sig sammen (Vasoconstriction)

25
Q

What is the normal range of blood pressure? xxx/xx?

A

120/80.
120 = Systolic pressure
80 = Diastolic pressure

26
Q

Donating blood. Minimum time you must regrain from flying duties?

A

24 hours.

27
Q

What is meant by “Con” and “delation”

A

Con trækker sig sammen.

Delation udvider sig

28
Q

The function of Atria?

A

Acts principally as entryways to the ventricles ebut they also pump weakly to help move the blood on through the atria into the ventricles. Thereby increase the effectiveness of the ventricles as pumps.

29
Q

The functions of the right and left ventricle?

A

Right ventricle pump deoxygnated blood to the lungs and the left ventricle pumps the oxygenated blood around the boyd

30
Q

Pulmonary omhandler altid?

A

Lungerne

31
Q

What is stroke volume?

A

is the volume of blood pumped from the left ventricle per beat.

32
Q

Minute volume?

A

is the volume of gas inhaled or exhaled from a person’s lungs per minute.

33
Q

What makes up the circulatory system?

A

The heart

Blood vessels:
The arteries
The Veins
The capillaries

34
Q

What blood vessels do when experiencing cold conditions and warm conditions

A

Vasoconstriction - The vessels constrict and move inwards towards the warmth

Vasodilation - Move outwards towards the skin and dilate to lose heat

35
Q

Arteries do?

A

Carry o2
Red in diagrams (usually)
Move blood away from the heart
Work under much higher pressure than the veins

36
Q

Veins do?

A

Transport de-o2 blood
Usually blue in diagrams
Carries de-o2 blood to the heart
Have valves in them to prevent back flow

37
Q

Vital capacity

A

5L . max ex breathing
