INTRODUCTION
This comprehensive WGU D312 Anatomy and Physiology I with Lab examination is designed to assess the
student's understanding of the structure and function of the human body. It evaluates knowledge of anatomical
terminology, the skeletal, muscular, nervous, endocrine, and cardiovascular systems. The laboratory component
emphasizes practical application of anatomical concepts. Candidates will be challenged to analyze the relationship
between structure and function, understand physiological processes, and apply anatomical knowledge to clinical
,scenarios. This rigorous assessment mirrors the complexity of the laboratory and lecture components of the course
and is structured to reflect the official WGU D312 examination blueprint.
SECTION ONE
Questions 1–100
Question 1
The anatomical position is defined as:
A. Lying face down with arms at the sides.
B. Standing erect, facing forward, with arms at the sides and palms facing forward.
C. Lying face up with arms outstretched.
D. Standing erect, facing forward, with arms crossed over the chest.
🟢 Correct Answer:
B. Standing erect, facing forward, with arms at the sides and palms facing forward.
🔴 RATIONALE:
The anatomical position is a standardized reference position. It is defined as standing erect, facing forward, with
,arms at the sides and the palms facing forward. This position is used to describe directional terms and
relationships.
Question 2
The term "proximal" means:
A. Farther from the point of attachment.
B. Closer to the point of attachment.
C. Toward the midline of the body.
D. Away from the midline of the body.
🟢 Correct Answer:
B. Closer to the point of attachment.
🔴 RATIONALE:
Proximal means closer to the point of attachment to the trunk or the point of origin. Distal means farther from
the point of attachment. Medial is toward the midline; lateral is away from the midline.
Question 3
The body cavity that contains the brain is the:
, A. Thoracic cavity.
B. Cranial cavity.
C. Abdominal cavity.
D. Pelvic cavity.
🟢 Correct Answer:
B. Cranial cavity.
🔴 RATIONALE:
The cranial cavity contains the brain. The spinal cavity contains the spinal cord. The thoracic cavity contains the
heart and lungs. The abdominal cavity contains the digestive organs.
Question 4
The serous membrane that surrounds the heart is the:
A. Pleura.
B. Peritoneum.
C. Pericardium.
D. Meninges.
🟢 Correct Answer:
C. Pericardium.
