Respuesta
-
left
-
right
Pregunta 2
Pregunta
The lungs ahve a large surface area to increase the rate of diffusion. Select anyother properties it has to do so
Respuesta
-
Many alveoli
-
Lots of cappileries suronding the alveoli
-
A large wall to help things diffuse across
-
A small wall to help things diffuse across
-
a low concentration gradient of O2 in the lungs
-
A high concentration gradient of O2 in the lungs
-
A low concentration of CO2 in the blood
-
A high concentration of CO2 in the blood
Pregunta 3
Pregunta
Foetal haemoglobin curves are shifted to the right.
Respuesta
- True
- False
Pregunta 4
Pregunta
The primary structure of Haemoglobin is the [blank_start]sequence of amino acids[blank_end]. The secondary structure is when it folds to [blank_start]form an alpha helix[blank_end]. The tertiary structure is when it folds even more. The quaternary structure is when there is [blank_start]more than one polypeptide chain[blank_end]. The iron is a [blank_start]prosthetic group[blank_end] to the protien.

Pregunta 7
Pregunta
During inspiration the [blank_start]external intercostal[blank_end] muscles, [blank_start]contract[blank_end] bringing the ribcage up and outwards. The diaphragm contracts moving [blank_start]down[blank_end]. This [blank_start]increases[blank_end] the thoraic cavity's volume and the lungs expand. This decreases the presure inside the lungs. The air therefore moves [blank_start]into[blank_end] the lungs.
Respuesta
-
external intercostal
-
internal intercostal
-
contract
-
relax
-
down
-
up
-
increases
-
Decreases
