Outline the physical and chemical factors controlling gas exchange between the alveoli and pulmonary capillaries.
Outline the physical and chemical factors controlling
gas exchange between the alveoli and pulmonary capillaries. Diagram
and describe the local signals and responses that help match
ventilation and perfusion.

What is the mechanism of gas exchange between alveoli and
pulmonary capillaries? Compare the gas pressures in the pulmonary
capillaries to the gas pressures in the alveoli, in a normal person
at rest.
(4pts) A young woman is snorkeling and (as an observant
physiology student) you understand that she must increase her tidal
volume and/or her breathing frequency to maintain her alveolar
ventilation rate. Why?
(2pts) Briefly describe how the respiratory membrane works. What
cell types and what forces allow...

pulmonary capillaries? Compare the gas pressures in the pulmonary
capillaries to the gas pressures in the alveoli, in a normal person
at rest.
The volume of inhaled air where there is no exchange of gases
with the pulmonary capillaries is called the:
A. Residual Volume
B. Functional Residual Capacity
C. Inspiratory Volume
D. Dead Space
E. Vital Capacity
1. Describe the capillary exchange of gases, nutrients and waste
in both pulmonary and systemic capillaries.
2. Trace a drop of blood through the cardiovascular system using
the appropriate terms, start and end at the same location.
Internal respiration refers to the exchange of gases between the
blood in ____________ capillaries and the tissue fluid. Internal
respiration services tissue cells, and without internal
respiration, cells could not continue to produce the ____________
that they need as an energy source. Blood in the systemic
capillaries is a ____________ color because of the presence of
oxyhemoglobin. Oxyhemoglobin gives up ____________ , which diffuses
out of the blood into the tissues. Oxygen diffuses out of the blood
into the tissues...
1. Gas Exchange and Transport
(A) Discuss the factors affecting gas exchange in the lungs
(B) Discuss the factor affecting the transport in the blood
C) Discuss the effect of bicarbonate on oxygen transport
(D) Discuss oxygen/carbon dioxide exchange at the tissue
level
Explain in detail the
mechanisms of fluid exchange between capillaries and the
interstitium. Then, define edema, and use cause-and-effect
arguments, explain how each of the following conditions cause
edema. Be sure to explain the underlying mechanism causing the
edema.

• Lymphatic filariasis (elephanaiasis) and parasitic infection
with a type of nematode.
• Surgical removal of lymphatic collecting vessels and lymph
nodes. For example in cancer treatment.
• Pregnancy. Specically: gestational edema due to the pressure
of uterus on the IVC...
