Nothing!
There are two parts to each option: - rate of gas diffusion (increased/decreased) - structures involved (bronchi and blood/alveoli and blood) Let's try to sort out which is right for each part. If you lose part of the lung, would you expect the rate of gas diffusion to increase or decrease?
Right! Less lung means less gas can diffuse at once. This narrows the choices down to B or C. Now for the second part. Which structures are involved in gas diffusion?
Yup - the bronchi are the big tubes that branch off from the trachea and just conduct air to bronchioles, which become smaller and smaller until they eventually terminate at alveoli. The alveoli are the little sacs that are surrounded by capillaries in order to help gases diffuse easily between the lungs and the blood. So if the rate is reduced, and the alveoli are involved, then C is the answer! Make sense?
C is correct. Basically the abdomen expands in an attempt to stretch out the diaphragm and expand the thoracic cavity where the lungs are in order to accomplish the same thing the diaphragm should be doing on its own. The diaphragm is a major inspiratory muscle and so this would occur during inspiration rather than expiration.
The answer is definitely either A or B, because bile wouldn't create a burning feeling no matter where it is. The difference between A and B is the sphincter we're talking about. The cardiac sphincter is the sphincter that separates the esophagus from the stomach, so named because it's near the heart. The pyloric sphincter separates the stomach from the first part of the small intestine (the duodenum), so named because it's nearest to the part of the stomach called the pylorus. Which do you think is right?
Exactly right!
Btw, this is known as heartburn, and is a reason people take antacids (e.g. Alka-Seltzer).
No problem! Again, there are two parts to each option: - What does the absorbing (lacteals/capillaries) - What is absorbed (carbohydrates and proteins/fats and fatty acids) We're talking about bile. Bile is made from what?
Right! So which answer would it be?
That's the one :)
the choice you made is right but bile is not made of fats and fatty acids it has a lot of components but basically bile acts to emulsify/mechanically break down fats for them to be then absorbed
you are right :)
okay question for you where is pancreatic duct? what does it connect to what?
so what do you expect it to transport? digestive enzymes? or hormones?
bingo and what are hormone transported in ?
good job :)
what is latin word for stuff related to liver?
so what does it tell you
what kind of cells would liver have?
type of cells/cell name i mean acinar cells hepatocytes ?
and so what function do u expect them to have?
now here is where its a bit hard to answer because it does deal with carbohydrates BUT it also deals with fats digestion of carbohydrates is mainly in small intestine (saliva and a bit in stomach also) so liver mainly deals with 'storage' system and regulating blood glucose level (ofc not without hormones) but remember what does liver produce? bile what does bile do?
what do you mean by 'cleans the system'?
did you read what i said earlier? if not please go up and find where i talked about bile
:) for more info you can read here http://www.vivo.colostate.edu/hbooks/pathphys/digestion/liver/bile.html
i believe so too lol
yeah better
