3) tissue
4) organ structure
5) organ system
6) organism
The necessary life function that protects our internal environment from our external
environment is provided by what system? - ANSWER-The integumentary system
The function of movement is provided by what system? - ANSWER-The muscular
system
The function of responsiveness is provided by what system? - ANSWER-The nervous
system
The function of digestion is provided by what system? - ANSWER-The digestive system
What is anabolism? - ANSWER-When more complex structures are synthesized from
simpler ones.
What is catabolism? - ANSWER-When more complex structures are broken down into
simpler ones.
Excretion involves what systems? - ANSWER-The respiratory system, the digestive
system, and the urinary system.
The reproductive system is controlled by what other system? - ANSWER-The endocrine
system.
These cuts/sections are made diagonally between the horizontal and vertical planes. -
ANSWER-oblique
This body cavity protects the nervous system. - ANSWER-dorsal body cavity
This body cavity encases the brain. - ANSWER-cranial
, This cavity encloses the spinal cord. - ANSWER-spinal
The frontal plane is also known as what plane? - ANSWER-coronal
The ventral body cavity is divided into these two cavities. - ANSWER-thoracic and
abdominopelvic
This cavity encloses the heart. - ANSWER-pericardial
The outer surfaces of the organs and body cavities are covered by this double layered
membrane called what? - ANSWER-serosa
What is pleurisy? - ANSWER-inflammation of the pleurae, which impairs their lubricating
function and causes pain when breathing. It is caused by pneumonia and other
diseases of the chest or abdomen.
The abdominopelvic region is divided into what four quadrants? - ANSWER-right upper,
left upper, right lower, and left lower
This region surrounds the naval. - ANSWER-umbilical region
This region houses the pelvis. - ANSWER-illiac region
This cavity houses the teeth and tongue. - ANSWER-oral cavity
This cavity houses the eyes. - ANSWER-orbital cavity
Joints are lined with what? - ANSWER-synovial fluid
This cavity contains the tiny ear bones, name them. - ANSWER-middle ear: malleus,
incus, and stapes
Why do active metabolizing cells need to be relatively small? - ANSWER-Active
metabolizing cells need to be relatively small so that the metabolic processes can occur
at a faster rate. As a cell gets bigger the ratio of surface area to volume decreases. The
larger the surface area of a cell is relative to its volume, the faster metabolic processes
can occur.
What are three differences between prokaryotic and eukaryotic cells? - ANSWER-1)
Prokaryotic cells do not have a nuclear membrane whereas eukaryotic cells do
2) prokaryotic cells are usually smaller than eukaryotic cells
3) prokaryotic cells lack membrane-bound organelles that are found in eukaryotic cells.
What is the function of the nucleus? - ANSWER-The nucleus stores DNA and is the
control center of the cell.
