Why does heart rate increase when we inhale and decrease when we exhale?
Why does heart beats faster when you breathe in and beats slower when we breathe out? what is its realationship with baroreceptor reflex control?

when you breath in, the lungs expand, reducing space aroudn the heart. the heart can't expand as much, and makes up for it by beating faster. like wise, when we breathe out, the lungs get smaller, the heart can expand more, and to maintain the same amt of metabolism, reduces the rate. the baroreceptors indirectly control heart rate by reacting to the c02 in the blood.

Some books say it is because of pressure changes caused by breathing.

Simply enough, your heart draws oxygen from your lungs into your blood. When you inhale, you give it oxygen to process which forces it to work, therefore speeding it up. When you exhale, CO2 is drawn from your lungs to be replaced with fresh air, While this exchange takes place your heart relaxes because it has no oxygen to process.


Macho-man
When we inhale, air enters our lungs and so more oxygen is available to be pumped through the body by way of the respiratory system, and thus the heart pumps faster to use all the oxygen in our lungs while it's still there. It beats slower when we exhale because there is no more air inside the lungs (or, not as much), so the heart can't deliver more oxygen and it slows down. I don't know what the baroreceptor reflex control is though. Sry.
