Q

What are the respiratory epithelium?

A

Ciliated, pseudo-stratified, columnar
Goblet
Basal

17
Q

What is the respiratory membrane?

A

Barrier between alveolar air and blood

18
Q

What is alveolar respiration?

A

Gasses exchange between alveoli and blood

19
Q

How’s does oxygen diffusion in the lungs take place effectively ?

A

Large surface area on the lungs allows large amounts of gases exchange
Thin respiratory membrane allows diffusion to happen fast over a short distance
Extensive blood supply to surrounding alveoli
Different gradients between alveoli and pulmonary venule

20
Q

What is internal respiration?

A

Gases exchange at systemic capillaries

Oxygen is unloaded to the tissues and taken up but cells - reverse for co2

21
Q

What is cell respiration?

A

Usually involve use of oxygen and glucose to produce energy in a process known as aerobic respiration
Glucose + O2 -> CO2 + water + ATP

22
Q

What interactions take place with the respiratory system?

A

Circulatory system-transport of blood gases and gas exchange
Nervous- respiratory centres in the brain
Musculoskeletal- enables inhalation and exhalation

23
Q

What are the three stages involved in respiration?

A

Pulmonary ventilation
External respiration
Internal respiration

24
Q

What is pulmonary ventilation?

A

Breathing via inspiration and expiration

25
Q

What is external respiration?

A

Gases exchange within the lungs

26
Q

What is internal respiration?

A

Gases exchange from capillaries to the tissues

27
Q

What happens at pulmonary ventilation?

A

Air flows because of pressure between the atmosphere and the gases inside the lungs
Volume of thoracic cavity changed by the diaphragm and rib cage

28
Q

What is Boyles law?

A

Describes the relationship between pressure and volume it’s states that as volume increases pressure descreases

29
Q

What happens during inspiration?

A

Air moves from an area of high pressure or an area of low pressure

30
Q

What happens in exhalation?

A

Muscles relax and elastic recoil causes lung volume to decrease and pressure to increase causing air to flow out

31
Q

What muscle are involved in respiration?

A

Inhalation - diaphragm and intercostal

Exhalation - little or none
