A collection of tissue that carry out a specialized function of the body.
Our body is made of cells and when the same cells come together, they form a tissue. Different tissues form an organ. Different organs form an organ system and different organs form an organism. This is a simple way to understand an organism by 'pieces' instead of learning it all at one time. You will find that most studies: math, chemistry, physics are done in this way.
In biology, a Biological system (or Organ system) is a group of organs that work together to perform a certain task. Common systems, such as those present in mammals and other animals, seen in human anatomy, are those such as the circulatory system, the respiratory system, the nervous system, etc.
The levels or organization are: cells -->tissues--->organs--->organ systems--->organism. The heart is an organ of the organ system called the cardiovascular system. This includes the heart, veins and arteries and blood.
