The next level is
the organ system level
. Many organs working together to accomplish a common purpose create an organ system. For example, the heart and the blood vessels of the cardiovascular system circulate blood and transport oxygen and nutrients to all the body cells.
What level of organization does the heart muscle fall under?
At the
tissue level
, cardiac muscle is striated (or striped) since, like skeletal muscle, it has organized sarcomeres.
Which level of organization is a heart at?
An
organ system
is a higher level of organization that consists of functionally related organs. Mammals have many organ systems. For instance, the circulatory system transports blood through the body and to and from the lungs; it includes organs such as the heart and blood vessels.
What is the organ level of organization?
The organ level of organization is
when two or more tissues work together for a specific function
. For example, the bladder consists of an inner lining of epithelial tissue, bound by various connective tissues to (smooth) muscle.
What are the levels of human organization?
It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity:
subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms and biosphere
(Figure).
What are the six levels of organization?
independent individual. Summarizing: The major levels of organization in the body, from the simplest to the most complex are:
atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism
.
What are the 10 levels of biological organization?
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
.
Which is cardiac muscle?
Cardiac muscle is an
involuntary striated muscle tissue found only in the heart
and is responsible for the ability of the heart to pump blood.
Is the heart a strong muscle?
The hardest working muscle is the heart
. It pumps out 2 ounces (71 grams) of blood at every heartbeat. Daily the heart pumps at least 2,500 gallons (9,450 liters) of blood. The heart has the ability to beat over 3 billion times in a person’s life.
What are the levels of organization from smallest to largest?
The levels, from smallest to largest, are:
molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere
.
What are 4 levels of organization?
An organism is made up of four levels of organization:
cells, tissues, organs, and organ systems
.
What are the levels of organization in an ecosystem?
Ecosystems are organized to better understand the frame of reference in which they are being studied. They are organized from
smallest to largest; organism, population, community, ecosystem
.
What are the 12 organs of the body?

- The lungs. …
- The liver. …
- The bladder. …
- The kidneys. …
- The heart. …
- The stomach. …

What are 6 characteristics of life?
All living organisms share several key characteristics or functions:
order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing
. When viewed together, these characteristics serve to define life.
What is the smallest level of structural organization in the human body?
The
cellular level
is considered when a variety of molecules combine to form the fluid and organelles of a body cell. A cell is the smallest independently functioning unit of a living organism. Even bacteria, which are extremely small, independently-living organisms, have a cellular structure.
What is the smallest unit of life?
The cell
is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.
