Almost all spices tend to have volatile aroma compounds and not flavor compounds like sugar, salt, acid, or glutamates. They may occasionally be bitter though. Aromas and taste work by different chemistries. Sugar, salt, citric acid, and MSG all have taste but not smell. Some foods like many fruits, have both fruity esters and essential oils, while also having sugars and acid which gives them both.
The sound of a heartbeat is caused by the heart valves opening and closing as they pump blood. When the heart is working properly, blood can only flow in one direction. The valves make this possible by opening and closing in exact coordination with the heartâs pumping action.
Heart murmurs are heart sounds produced when blood flows across one of the heart valves that is loud enough to be heard with a stethoscope. There are two types of murmurs. A functional murmur or  physiologic murmur is a heart murmur that is primarily due to physiologic conditions outside the heart. Other types of murmurs are due to structural defects in the heart itself. Functional murmurs are benign (an  innocent murmur ). Murmurs may also be the result of various problems, such as narrowing or leaking of valves, or the presence of abnormal passages through which blood flows in or near the heart.
