Levels of Organization
Organisms is the scientific word for....
Living Thing(s)
The primary job of this nutrient is to provide quick energy for your brain and muscles.
Carbohydrates
The two types of digestion are mechanical and this.
Chemical digestion
Roots perform two main functions: to support the plant and to do this for water and substances from the soil.
Absorb
This tube, also called the windpipe, carries air from the pharynx down into the chest.
Trachea
These are groups of similar cells that work together to carry out specific tasks.
Tissues
The primary job of this nutrient is to build and repair your body.
Proteins
Digestion begins in this organ, where saliva is produced to begin breaking down carbohydrates.
Mouth
The skeletal system is made up of more than 200 of these, plus ligaments and joints.
Bones
The plant vascular tissue that carries dissolved sugars throughout the plant.
Phloem
The heart and lungs are examples of this level of organization.
Organs
This nutrient's job is to provide structure for things like bones (Calcium) and blood (Iron).
Minerals
This is the process of physically breaking food into smaller pieces, such as by chewing, mashing, or grinding.
Mechanical Digestion
Found in the knees and elbows, this type of joint allows movement back and forth in a single direction.
Hinge Joint
These tiny blood vessels connect arteries and veins and are where oxygen and nutrients are exchanged with body cells.
Capillaries
The digestive system is an example of this most complex level of organization, where different organs work together to complete a series of tasks.
Organ System
This nutrient's primary job is to act as regulators and help boost your immune system.
Vitamins
Food moves through the esophagus by these waves of muscle contractions, similar to squeezing a toothpaste tube.
Peristalsis
This type of involuntary muscle lines blood vessels and many organs, moving material through the body.
Smooth Muscle
This is the term for the system, seen in a bee, that transports blood and other fluids into open spaces that surround organs.
Open Circulatory System
The process by which the first cells made in a multicellular organism can become any type of specialized cell.
Cell Differentiation
Along with providing long-lasting energy, the other key job of this nutrient is to protect your internal organs.
Fats
This large, hollow organ produces the acidic gastric juice, which contains the enzyme pepsin.
Stomach
This term describes the thick, hard outer covering found on animals like crabs and snails that protects and supports their bodies.
Exoskeleton
These tiny air sacs inside the lungs are the location where oxygen enters the blood and carbon dioxide leaves it.
Alveoli
