QUESTION
What is a pneumothorax
Answer:
air in pleural space; collapsed lung
With Boyle’s law, as the pressure falls during ascent, an inversely proportional rise in gas volume
occurs causing expansion of air in gas-filled bodily chambers such as a closed pneumothorax.
QUESTION
be able to label this graph
Answer:
TTIERV
QUESTION
Signs of inflammation
Answer:
Rubor (redness) Dolar (Pain)
Calor (heat) Tumor (swelling)
QUESTION
differences between helper t cells, memory t cells, cytotoxic t cells
Answer:
cytotox- ic T cells destroy virus-infected cells and tumor cells
helper T cells secrete cytokines to activate other cells in the immune system triggering a specific
immune response, stimulates killer t cells, macrophages and b cells
QUESTION
Describe ventilation
Answer:
Ventilation is the movement of air in and out of the lungs. Air moves due to pressure gradients
contracting the thoracic muscles and diaphragm.
QUESTION
Describe internal respiration
Answer:
The exchange of carbon dioxide and oxygen between the cells of the body and blood by fluid
bathing the cells. Oxygen diffuses out from the blood into the tissue.
QUESTION
Describe external respiration
Answer:
Breathing and the exchange of gases between the lungs and external environment as well as
between the alveoli and surface and blood stream.
