respiraton

Question 1

what does the respiration system provide

Answer 1

oxygen

Question 2

why does the body system provide oxygen

Answer 2

to allow the body to carry out the process of respiration. To allow cells to grow
produce
fight infection
carry out active transport

Question 3

adaptions of respiratory surfaces

Answer 3

1. large surface areas
2. Thin
   3.moist
3. permeable
4. rich blood supply
5. diffusion gradient
   7 aveoli?

Question 4

how is large surface area adapted to respiratory surfaces

Answer 4

increases opportunity for gas exchange.

loosely packed spongy mesophyll in a mesophytic leaf creates a large surface area for gas exchange

Question 5

how does thin make it adapted to respiratory surfaces

Answer 5

reduces diffusion distance and speeds up the rate of diffusion
walls of alveoli are one cell thick

Question 6

how is moist adapted

Answer 6

gases must dissolve in liquid before the can diffuse.

inside the alveoli

Question 7

how is permeable adapted

Answer 7

allows gases to pass through respiratory surfaces

Question 8

how is rich blood supply adapted

Answer 8

alveoli surrounding by dense capillary network.

Blood moving ensures that diffusion
