Respiratory system

Question 1

what is ventilation?

Answer 1

process of moving in and out of the lungs and internal, bringing oxygen in and removing carbon dioxide

Question 2

what is fricks law?

Answer 2

but diffusion is proportional to=
Surface area x concentration gradient/ thickness.

Question 3

what do cells are involved in defence mechanisms of the respiratory system?

Answer 3

• goblet cells: produce
• Ciliated cells: have cilia

Question 4

What is the area inside the ribs called?

Answer 4

thorax

Question 5

What type of cells is alveoli made out of?

Answer 5

squamous cells

Question 6

what are three adaptations of alveoli?

Answer 6

• there, once a fixer, there’s a short diffusion path
• they have a large surface area and there are millions of them
• There is always a constant concentration gradient

Question 7

What is the muscle in between the ribs called?

Answer 7

Intercostal muscles

Question 8

What happens during inspiration?

Answer 8

• The rips move up and out
• external intercostal muscles contract
• diaphragm contracts and flattens
• Thorax increases in volume decrease in pressure
• Air moves into the lungs

Question 9

What happens during expiration?

Answer 9

• The ribs move down and in
• Internal intercostal muscles contract
• The diaphragm, relaxes and arches
• The thorax, volume decreases and the pressure increases
• Air moves out

Question 10

name a few respiratory diseases:

Answer 10

• emphysema (damage to the alveoli)
• Conary heart disease
• Chronic bronchitis (information of the bronchi)
