1.When you have a heart attack that means that there has been a sudden blockage in one of your coronary arteries and the coronary arteries are the blood vessels that supply the heart muscle with oxygen.
We know the heart is full of blood, but it’s actually the coronary arteries that give that to the heart muscle. In a heart attack situation the heart muscle or part of heart muscle is being deprived of oxygen and will ultimately die. The main symptoms would be a pretty sudden onset chest discomfort, often described as a heaviness or tightness which can spread to the arms or even the neck or jaw.
2.A normal resting heart rate is between 60 and 100 beats per minute.
3.hydra live in water and do not have blood or any circulatory system. Water acts a carrier of food and oxygen to their body and it also carries out waste material and carbon dioxide from the body.
In simple multicellular organisms like Hydra, the transportation of material from cell to cell takes place through simple diffusion.
