What hormone dilates bronchioles increases heart rate?
There is not an actual hormone which increases blood pressure. However, the hormone adrenaline is secreted by the pituitary gland and has the effect of speeding up the contraction of the heart muscle. In turn this leads to increased blood pressure due to Fick's Law. The stroke volume of the heart has increased so more blood is being forced through the network of blood vessels
What is the difference between inotropic and cronotropic?
Inotropic refers to the force of contraction of the heart muscle, while chronotropic refers to the heart rate. Inotropic agents affect the strength of the heart's contractions, while chronotropic agents affect the heart rate.
A hormone that increases your heart rate in time of danger?

What is the hormone that is released by the heart when the fluid volume increases?

What hormone increases heart rate and force of contraction?
Cardiac output is defined by the equation HR (heart rate) x SV (stroke volume). Anything that increases either of these will increase the cardiac output. Increasing heart rate: exercise, anxiety, caffeine, amphetamines, cocaine, other medications Increasing stroke volume: certain medications (digoxin, etc), lower heart rates
Which hormone when secreted increases heart beats?
Adrenalin also called Epinephrine

What happens to a frogs heart rate when temperature changes?
the rate of contraction increases with a rise in temperature and decreases with a fall in temperature
Why do we have valves in our hearts?
We have valves in our hearts to prevent backflow of blood during contraction. This control of flow increases the efficiency of the heart.
How body reacts when adrenaline hormone is secreted in the blood?
Too much of a certain hormone in the body is not really good for the body as it is very harmful. It gets to your head longterm; nervous one day, aggressive the next and unpredictable overall. You can wreck your circadian rhythm, have a panic attack, a nervous breakdown-everything goes haywire-might snap on your friends if you don't seek medical attn.
Increased return of the blood to the heart stretche's the muscle which does what?
increases the heart rate. ---- Increases the force of contraction, and therefore, the amount of blood pumped out at a time. Think of a rubber band...the more you stretch it, the harder it contracts when you let go.
