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 sounds during your heartbeat cycle â such as whooshing or swishing â made by turbulent blood in or near your heart. These sounds can be heard with a stethoscope. A normal heartbeat makes two sounds like lubb-dupp (sometimes described as lub-DUP), which are the sounds of your heart valves closing.
