Quiz 4, Card set 4

Question 1

How gases are transported in the blood. Include O2, CO2, and CO

Answer 1

O2:
Dissolved in plasma as O2 molecules.
Bound to hemoglobin: Majority transported bound to hemoglobin, forming oxyhemoglobin.

CO2:

carried as CO2 and bicarbonate ions (HCO3-)

Bound to hemoglobin: Some binds as carbaminohemoglobin.

CO:
Bound to hemoglobin: high affinity, forms carboxyhemoglobin, reducing

Question 2

Dalton’s Law (formula)

Answer 2

Ptotal= P1 +P2 + P3+ …

Temp and vol constant

Question 3

Henry’s Law (formula)

Answer 3

C = k P

C = concentration of a dissolved gas
k = Henry’s Law constant
P = partial pressure of the gas

Question 4

How Dalton’s law to the events of external and internal respiration

Answer 4

Gases move from an area of high pressure to low pressure

Question 5

How Dalton’s and Henry’s law to the events of external and internal respiration

Answer 5

Dalton’s Law: governs respiratory gas exchange.
Henry’s law says: Gases move according to their partial pressures.
External respiration: oxygen to blood, carbon dioxide out of lungs.
Internal respiration: oxygen to tissues, carbon dioxide to blood.
Movement guided by pi differences.
Gases move from an area of High pressure to an area of low pressure
