Re: Anatomy and Physiology B/C
Ok, last one (for now )
27. Which of the following INCREASES hemoglobin binding affinity for oxygen?
I. 2, 3-diphosphoglycerate
II. increase in blood pH
III. increase in temperature
a. I only
b. II only
c. I, II
d. II, III
e. None of the above
The answer was b, but doesn't increased blood pH actually cause oxygen detachment.

However, the event anatomy itself is never swapped out for another one.nshezad123 wrote:No, the systems change every year.jlordhe wrote:Is Anatomy a permanent event(one that does not rotate)?

Re: Anatomy and Physiology B/C
Just a quick question, are the three walls of the heart the epicardium, endocardium, and myocardium or pericardium, endocardium, and myocardium? Because I thought the pericardium was the outermost layer of the heart, but the University of Florida invitational (C) said it was epicardium.

Re: Anatomy and Physiology B/C
I think this may be because the pericardium is the sac that surrounds the heart and isn't officially a layer of the heart. Therefore, the epicardium is the outermost layer of the heart, making the three walls the endocardium, myocardium, and epicardium.WangwithaTang wrote:Just a quick question, are the three walls of the heart the epicardium, endocardium, and myocardium or pericardium, endocardium, and myocardium?

Re: Anatomy and Physiology B/C
The pericardium is a sac enclosing the heart or surrounding the heart wall, rather than being an actual layer of the heart wall.WangwithaTang wrote:Just a quick question, are the three walls of the heart the epicardium, endocardium, and myocardium or pericardium, endocardium, and myocardium?

oh, okay. But isn't the epicardium part of the pericardium?Here wrote:The pericardium is a sac enclosing the heart or surrounding the heart wall, rather than being an actual layer of the heart wall.WangwithaTang wrote:Just a quick question, are the three walls of the heart the epicardium, endocardium, and myocardium or pericardium, endocardium, and myocardium?

The layers of the pericardium not including the epicardium include great vessels, while the epicardium layer just encloses the heart, making it considered one of the walls of the heart.
