The Respiratory System

Question 1

Which of the following did you include in your response? Check all that apply.

Revolt · Accepted Answer

During inhalation, the diaphragm contracts and moves downward, increasing the space in the chest cavity. Air is sucked in through the nose and mouth and eventually travels to the lungs, which expand.; During exhalation, the diaphragm relaxes and moves upward, reducing the space in the chest cavity. This forces carbon dioxide out of the lungs through the nose and mouth.

Question 2

What happens within the respiratory system when someone has hiccups? What can cause hiccups?

Revolt · Accepted Answer

When the diaphragm becomes irritated, it jerks down, which causes air to rush quickly into the throat. When this air hits the voice box (vocal cords), it causes the sound of a hiccup. Hiccups can be caused by various factors, such as eating too quickly or too much, having an irritated stomach or throat, or experiencing feelings of nervousness or excitement.

Question 3

What is a lung transplant?

Revolt · Accepted Answer

A lung transplant is a surgery in which a diseased or failing lung is removed and replaced with a healthy lung, typically from a deceased donor.

Question 4

Why are people on the donor list given a lung allocation score and which factor has been eliminated as a reason for a transplant?

Revolt · Accepted Answer

The Lung Allocation Score (LAS) is used to determine which patients would benefit most from a transplant based on medical urgency and predicted post-transplant survival. The score is calculated using clinical data like age, oxygen requirement, pulmonary function, and the distance a patient can walk in six minutes. This system was implemented so that the amount of time spent on the donor waiting list is no longer the primary factor used to determine who receives a transplant.
