What organ is responsible for compensation when there is a metabolic problem and what chemical is it ultimately changing?

Lungs, it will speed up or slow down respiration in order to change the concentration of H2CO3.

What organ is responsible for compensation when there is a respiratory problem and what chemical's concentration is ultimately changed?

The kidney will either secrete or reabsorb HCO3- in order to compensate.

What is the normal response for an agonist that binds a cardiac RM2 receptor?

Inhibitory, slow down the heart rate.

What is the normal response for an agonist that binds a respiratory smooth muscle cell RM3 receptor?

constriction which leads to a smaller diameter conducting airway.

What is the normal response for an agonist that binds a respiratory mucous cell's RM3 receptor?

Increases the amount of mucous secretion and production.

Give an example of an organophosphate poison? How does this poison enter the body? What is the effect that these poisons have on the body?

Nerve gas/DFP/Sarin. Can either be inhaled or skin contact. They destroy achase.

If a person inhales or comes into contact with nerve gas, describe what would happen to them, physiologically.

Increased ACH. At the RM2 cardiac receptor, it would slow down the heart rate. At the RM3 SMC receptor, it would cause it to constrict. At the Rn receptors of skeletal muscle, it would cause continuous contraction.

Which receptor response would occur the fastest as a result of being exposed to nerve gas?

Rm, because it is a receptor of the autonomic nervous system.

How could atropine help a person who has been exposed to nerve gas?

Atropine is a Rm receptor antagonist, and might bind to the receptors before the increased levels of Ach do.

What is the function of Surfactant?

It decreases the surface tension of the alveoli, allowing them to have compliance and fill up with air and also allowing for them to recoil.

What is RDS? What is another name?

Respiratory Distress Syndrome. Hyaline Membrane Disease (HMD)

Describe why diabetic mothers are more likely to have babies to develop RDS?

Because they are diabetic, there is an overload of glucose in the mother's blood. This blood is used to give nutrients to the baby and as a result the baby grows larger, faster. Large baby has to be induced before respiratory system is fully developed.

What is responsible for more neonatal deaths than any other condition? What is the chief predisposing face?	RDS. Premature birth.
Describe why diabetic mothers are more likely to have babies to develop RDS?	Because they are diabetic, there is an overload of glucose in the mother's blood. This blood is used to give nutrients to the baby and as a result the baby grows larger, faster. Large baby has to be induced before respiratory system is fully developed.
