Ope The human body is a fascinating object – a miracle of design and engineering! Just like an ecosystem can be subdivided (e.g.., organisms, populations, community), the human body can also be divided into From largest to smallest, the levels of organization in the human body are organism, organ, and cell. It all starts with tiny, units of objects hum along doing their job without you even knowing it! Though all cells perform called cells.

Examples of tissues include: nerves, muscles, which work together to perform the same function in the and connective. Muscle tissues and relax and allow the body to but there are three types of tissues: cardiac (controls skeletal (controls One common example is and provide (controls organs), and ). Epithelial tissues cover the surface of the body and the organs. Connective tissues connect all the parts of the body which conduct more Groups of tissues form tissues. One example of an organ is the nerve tissues, and cardiac muscle tissues. Although the tissues in organs have specific jobs, they all processes than which is made up of connective tissues, work to make the organ work.
