ANATOMY PHYSIOLOGY I | Advanced/Hard/Mixed | 100%
Pass Guaranteed | Graded A+
[1] Which of the following represents the correct order of structural organization from simplest
to most complex in the human body?
A. Tissue, Cellular, Organ, Chemical, Organ System, Organismal
B. Chemical, Cellular, Tissue, Organ, Organ System, Organismal
C. Cellular, Chemical, Organ, Tissue, Organ System, Organismal
D. Chemical, Tissue, Cellular, Organ, Organ System, Organismal
Correct Answer: B
Explanation: The hierarchy begins with the chemical level (atoms/molecules), followed by
the cellular level (cells), tissue level (groups of similar cells), organ level (two or more tissue
types), organ system level (related organs), and finally the organismal level.
[2] The body's ability to maintain a relatively stable internal environment despite external
changes is termed:
A. Metabolism
,2
B. Homeostasis
C. Anabolism
D. Catabolism
Correct Answer: B
Explanation: Homeostasis refers to the dynamic equilibrium maintained within the body's
internal environment. Metabolism encompasses all chemical reactions, while anabolism and
catabolism are specific types of metabolic reactions.
[3] In the standard anatomical position, which of the following is TRUE?
A. The palms of the hands face posteriorly
B. The feet are together and toes point forward
C. The arms are crossed over the chest
D. The body is lying face down
Correct Answer: B
Explanation: In the anatomical position, the body is erect, feet slightly apart and toes
pointing forward, arms at the sides with palms facing anteriorly (forward).
,3
[4] A plane that divides the body into equal right and left halves is called a:
A. Parasagittal plane
B. Frontal plane
C. Midsagittal plane
D. Transverse plane
Correct Answer: C
Explanation: A midsagittal (or median) plane divides the body into equal right and left
halves. A parasagittal plane divides it into unequal right and left portions. Frontal (coronal)
planes divide into anterior/posterior, and transverse (horizontal) planes divide into
superior/inferior.
[5] The heart is located in which body cavity?
A. Cranial cavity
B. Thoracic cavity
C. Abdominal cavity
D. Pelvic cavity
Correct Answer: B
, 4
Explanation: The heart is located in the thoracic cavity, specifically within the mediastinum
between the lungs. The cranial cavity houses the brain, the abdominal cavity contains digestive
organs, and the pelvic cavity contains reproductive and excretory organs.
[6] The pleural cavities contain which of the following organs?
A. The heart
B. The lungs
C. The liver
D. The stomach
Correct Answer: B
Explanation: The pleural cavities are the two lateral compartments of the thoracic cavity,
each surrounding a lung. The heart is in the pericardial cavity (within the mediastinum), while
the liver and stomach are in the abdominopelvic cavity.
[7] A cut through the body that separates the anterior from the posterior portions is made
along which plane?
A. Sagittal plane
