Total questions: 15
Worksheet time: 8mins
During (a) respiration, O2 moves from the air in the alveoli to the blood in the capillaries.
During internal respiration, (a) moves from the blood in the capillaries to the surrounding tissue fluid.
Which statement describes the conditions of the arterial side of a tissue capillary?
blood pressure > osmotic pressure
blood pressure < osmotic pressure
Which statement describes the conditions of the venous side of a tissue capillary?
blood pressure > osmotic pressure
blood pressure < osmotic pressure
What movement occurs at the arterial side of a tissue capillary?
O2 moves out of blood
O2 moves into blood
CO2 moves out of blood
CO2 moves into blood
What movement occurs at the venous side of a tissue capillary?
O2 moves out of blood
O2 moves into blood
CO2 moves out of blood
CO2 moves into blood
How is most O2 transported in the blood?
as tiny O2 bubbles
bonded to hemoglobin
as an ion in blood plasma
How is most CO2 transported in the blood?
as tiny CO2 bubbles
bonded to hemoglobin
converted to HCO3- ion
During external respiration, why does O2 move out of the alveoli?
blood pressure
osmotic pressure
diffusion
During external respiration, why does CO2 move out of the blood?
blood pressure
osmotic pressure
diffusion
H+ is created in the tissue capillaries because of the reaction that converts CO2 to HCO3-.
true
false
The pH of venous blood is extremely acidic due to the excess H+ created with HCO3-.
true
false
What happens to the excess H+ created with HCO3-?
stays in blood plasma causing pH to drop drastically
binds to hemoglobin for transport to lungs
Where does internal respiration take place?
alveoli & associated capillaries
body tissues & associated capillaries
in all organs of the respiratory system
which statements are true for cellular respiration?
glucose + O2 --> CO2 + H2O + energy
occurs in alveoli of lungs
occurs in mitochondria of all cells
occurs in tissue fluid
