What is the hierarchy of the structure of the human body?
Organism, organ systems, organs, tissues, cells, molecules, atoms
This system works as the transportation system for substances such as
oxygen, carbon dioxide, and nutrients in the body.
Circulatory system
This system breaks down food so that the nutrients can be easily passed
into the blood and circulated through the body
Digestive system
This system controls body functions
Endocrine system
This system protects internal tissues from injury, waterproofs the body,
and helps regulate the body temperature. This system also serves as a
barrier to foreign substances
Integumentary system
,This system helps cleanse the blood and houses the white blood cells that
are involved in protecting the body from environmental pathogens
Lymphatic system
This system produces movement through contractions
Muscular system
This system acts as the body's control system and is necessary to protect
the body from changes in the internal and external environment
Nervous system
This system produces offspring
Reproductive system
This system keeps all the cells in the body supplied with oxygen and
removes the carbon dioxide
Respiratory system
This system provides support and protection for the body, supplies a
framework use to create movement, and served as a storage for minerals,
such as calcium
Skeletal system
,This system helps maintain the water and electrolyte balance within the
body, regulates the acid base balance in the blood, and removes all
nitrogen-containing wastes from the body.
Urinary system
True or false: blood that passes through the tricuspid valve enters the left
ventricle
False, blood that passes through the tricuspid valve enters the right
ventricle
True or false: blood that passes through the mitral valve enters the
pulmonary artery
False, blood that passes through the mitrial valve enters the left ventricle
True or false: after contraction of the left ventricle, blood enters the aorta
True
True or false: after contraction of the right ventricle, blood enters the
pulmonary artery
True
True or false: after contraction of the right atrium blood enters the right
ventricle
True
, True or false: the pulmonary valve ensures that blood stays in the aorta
False, the pulmonary valve ensures that blood stays in the pulmonary
artery
The respiratory system supplies the body with ___ and removes ___
Oxygen; carbon dioxide
It is true the walls of the ___ that oxygen and carbon dioxide move in and
out of the capillaries in the lungs
Alveoli
During ___ the diaphragm contracts, the chest cavity enlarges, creating
negative pressure in the chest cavity and pulling air into the lungs.
Inspiration
When the diaphragm relaxes, carbon dioxide is forced out of the body
Expiration
An abdominal muscle that contrakt, pulls air into the lungs during
inspiration
Diaphragm
True or false: the nervous system directs bodily defenses against external
stimuli
True
