Week 11: Discussion - Group 4

Week 11: Discussion - Group 4

Discussion Instructions

Think about a response to all the questions listed below. Pick one and post an initial thread response. You’re required to also post a minimum of two interactive responses (to peers and/or to a follow-up question that I may present).

Choose one of the following discussion thread topics:

1. What is the primary function of the respiratory system? Difference between pulmonary ventilation, external respiration, and internal respiration?
2. Briefly describe how differences/changes in pressure determine air flow during inspiration and expiration. Primary method of oxygen transport? Primary method of CO2 transport?
3. Juan is anxious and begins to breathe rapidly…He’s hyperventilating. He’s given a brown paper bag to breathe in, which helps him slow down his breathing rate. Does this really work? If so, how mechanistically? Is it just the placebo effect?
4. How do partial pressure (pulmonary) pCO2 levels in the brain affect how we breathe? Understand normal blood pH and negative feedback. Briefly highlight compensatory breathing mechanisms for maintenance of normal blood pH.

Discussion Board GuidelinesDownload Discussion Board Guidelines

The Discussion Board (DB) is an academic discussion. As such, postings (including initial and

response postings) are expected to be substantial, to reflect application of relevant course

content, and to be supported with evidence from credible sources.

The following guidelines should be followed unless the instructions for a particular DB

specifically indicate otherwise:

One initial posting and 2 response postings are required, as a minimum, for each

discussion forum/board. Posts must be completed on at least two separate days.

Original posts should consist of at least 150 words (unless the assignment instructions are

different). Try not to exceed 300 words; however, no points will be deducted for longer

postings.

Response postings should consist of at least 75 words. Try not to exceed 300 words;

however, no points will be deducted for longer postings.

Timeliness is essential in the online discussion environment in terms of encouraging and

facilitating the exchange and development of ideas among members of the discussion

group. Nightingale College’s academic week runs from Monday at 12:00 am Mountain

Time (MT) to Sunday at 11:59 pm MT. All assignments for the week are due within the

academic week in which they are assigned, unless otherwise specified. Accordingly,

o Initial postings should be posted no later than Wednesday at 11:59 PM MT.

o The required response postings must be posted no later than Sunday at 11:59 PM

MT.

o The DB will officially close at 11:59 PM MT on Sunday and response postings

will not earn credit after this time.

▪ References should be included when applicable. References should be

formatted in a manner generally consistent with APA guidelines; however,

no points will be deducted for variations in line spacing and or indentation

(including "hanging" position for the first line of each entry).

▪ To avoid loss of content while your posting is under development, you

may wish to develop your postings in a MS Word document and then cut

and paste them into the DB. Please do not present your discussion

posting in the form of a MS Word document attachment.
