Follow this extremely helpful flow chart:
Cell ⇒ Tissue ⇒ Organ ⇒ Organ System ⇒ Organism
The heart is an organ because it is a collective of tissue functioning together.
-The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
-Organelles are small structures that exist within cells. Examples of these include: mitochondria and chloroplasts, which carry out indispensable functions. All living things are made of cells, and the cell itself is the smallest fundamental unit of structure and function in living organisms. A tissue is a group of related cells working together to perform a similar function .
-After tissues, organs are the next level of organization of the human body. An organ is a structure that consists of two or more types of tissues that work together to do the same job. Examples of human organs include the brain, heart, lungs, skin, and kidneys.
issues are further organized in organs, the third level of organization in living things. Organs are groups of different tissues that work together. Your heart, for example, is an organ made up of muscle tissue, blood tissue, and nerve tissue.
Explanation: A good way to remember is I am an organ donor... you donate organ your heart is an organ and can get donated...
Organ of circulation. Other organs are the blood vessels - arteries, veins and capillaries
The heart is an example of the organ level of organization.
The correct answer is - organ level organization.
The heart is made up of various types of tissues that include muscle tissue, nerve tissue, and blood tissue. All these types of tissues are organized to form the organ level organization which makes the heart is an organ.
Tissues are made up of cells and organs are made up of tissues and various organs combine together to do a specific function, this is an example of an organ system.
Thus, the correct answer is - organ level organization.
