Heart sounds are created by the relationship between the valves of the heart and the surface of the thorax.
Heart disease atheroscerosis is narrowing of the arteries.
they both have to do with a heart
The recovery heart rate tells you how fit you are. Thus the relationship between the two is simple. Athletes will have a low recovery rate making them very healthy and fit.
The physiological relationship between heart rate and blood pressure is that they are closely connected. When the heart beats faster, it pumps more blood, which can increase blood pressure. Conversely, when the heart beats slower, blood pressure may decrease. This relationship is important for maintaining proper circulation and overall cardiovascular health.
Arteries carry blood from the heart and veins carry blood to the heart.
It's between the covers, I suggest you start by looking there.
There is no symbiosis between a flea and a dog. The flea is a blood eating parasite on the dog. There is benefit to the flea but not to the dog so there is no symbiosis.
The relationship between heart rate and breathing rate is important for overall cardiovascular health.

Regular exercise can help improve this relationship, leading to better cardiovascular health.
The adrenal medulla is a part of the adrenal gland that releases hormones like adrenaline in response to stress or excitement. These hormones can affect the heart by increasing heart rate and blood pressure. So, the relationship between the heart and the adrenal medulla involves the adrenal medulla influencing the heart's activity through the release of hormones.
