BIOL252 / BIOL 252 Module & Lab 1 – Human Anatomy & Physiology II with Lab
(Portage Learning) | Study Guide, Questions & Answers 2026
This document is a comprehensive study resource for BIOL252 / BIOL 252: Human Anatomy
& Physiology II with Lab offered through Portage Learning. Module & Lab 1 focuses on the
composition and functions of blood, hemostasis, diagnostic blood testing, and foundational
cardiovascular physiology. The material includes practice questions, answer explanations, key
concepts, terminology reviews, and exam-preparation content designed to reinforce course
objectives and support student success. Human Anatomy & Physiology II covers major body
systems including the circulatory, lymphatic, respiratory, digestive, urinary, and reproductive
systems, with laboratory exercises and case-based applications.
Question 1
Which of the following descriptions accurately defines the standard anatomical position?
A) The body is seated, arms crossed over the chest, with palms facing inward.
B) The body is supine, feet wide apart, with palms flat against the thighs.
C) The body is standing erect, feet flat on the floor, arms at the sides, with palms
facing forward.
D) The body is prone, arms extended above the head, with thumbs pointing inward.
Rationale: Standard anatomical position serves as the universal reference frame for all
directional terms. It requires an erect stance with the upper limbs at the sides and the
palms turned forward so that the radius and ulna are parallel.
Question 2
A blood pressure reading shifts away from the homeostatic set point, triggering
mechanisms that cause blood vessels to dilate and return pressure back to normal. This
sequence is an example of which process?
A) A negative feedback loop
B) A positive feedback loop
C) Chemical cellular mutation
D) An systemic metabolic imbalance
Rationale: Negative feedback mechanisms work to reverse or counter a deviation from
the set point, bringing the internal variable back toward its normal physiological range.
Question 3
What structural level of organization is represented by a group of similar cells working
together to execute a shared, specialized function?
,A) Cellular level
B) Tissue level
C) Organ level
D) Organismal level
Rationale: The biological hierarchy progresses from chemical to cellular, and then to the
tissue level, which is defined as an aggregation of structurally similar cells working
together.
Question 4
The elbow is located __________ relative to the wrist.
A) Proximal
B) Distal
C) Inferior
D) Lateral
Rationale: The directional terms proximal and distal describe positions along limbs
relative to the trunk. Because the elbow sits closer to the point of arm attachment, it is
proximal to the wrist.
Question 5
Which vertical plane passes directly through the midline of the body, dividing it into
exactly equal right and left halves?
A) Frontal plane
B) Transverse plane
C) Midsagittal plane
D) Parasagittal plane
Rationale: A sagittal plane splits the body into right and left portions. If that split runs
directly down the anatomical midline to create equal halves, it is a midsagittal (or
median) plane.
Question 6
The lungs are located within which specific sub-cavity of the ventral body cavity?
A) Cranial cavity
B) Pelvic cavity
C) Pleural cavity
D) Pericardial cavity
Rationale: The ventral body cavity is divided by the diaphragm into thoracic and
abdominopelvic zones. The thoracic cavity contains two lateral pleural cavities, each
housing a lung.
Question 7
,What is the name of the double-layered serous membrane layer that directly wraps and
adheres to the external surface of the heart?
A) Parietal pleura
B) Parietal pericardium
C) Visceral pericardium
D) Visceral peritoneum
Rationale: Serous membranes consist of a parietal layer lining cavity walls and a
visceral layer covering the organs. The heart-specific membrane is the pericardium,
making visceral pericardium the layer that directly coats the cardiac tissue.
Question 8
A clinical checkup reveals a patient has acute inflammation localized in the right lower
quadrant (RLQ) of the abdomen. Which organ is the most likely source of this
discomfort?
A) Appendix
B) Stomach
C) Spleen
D) Gallbladder
Rationale: Knowing organ locations within the four quadrants is a core clinical skill. The
appendix is located in the right lower quadrant (RLQ), while the stomach and spleen sit
in the LUQ, and the gallbladder sits in the RUQ.
Question 9
Which of the following processes operates via a positive feedback loop?
A) Maintenance of core body temperature
B) Regulation of blood glucose concentration
C) Uterine contractions during childbirth
D) Maintenance of blood calcium parameters
Rationale: Positive feedback loops enhance or amplify the initial stimulus, driving a
variable further from its original baseline. This is seen during labor, where oxytocin
increases contractions until delivery is complete.
Question 10
The skin is located __________ relative to the underlying skeletal muscle layer.
A) Deep
B) Superficial
C) Proximal
D) Superior
Rationale: Superficial indicates a position closer to or at the external surface of the
body. The integumentary layer is superficial to the deep musculature.
, Question 11
What are the three core components of any homeostatic control system?
A) Atom, molecule, cell
B) Stimulus, response, threshold
C) Receptor, control centre, effector
D) Hormone, neurotransmitter, target
Rationale: A feedback loop requires a receptor to monitor and detect adjustments, a
control centre to analyze inputs against a set point, and an effector to execute the
physiological response.
Question 12
Which anatomical region corresponds directly to the front of the knee?
A) Popliteal
B) Patellar
C) Crural
D) Femoral
Rationale: Regional terms specify distinct body zones. Patellar refers to the anterior
knee cap area, whereas popliteal refers to the posterior knee crease.
Question 13
Which body plane splits the body horizontally into superior and inferior portions?
A) Sagittal plane
B) Coronal plane
C) Transverse plane
D) Frontal plane
Rationale: A transverse (or horizontal/axial) plane cuts perpendicular to the long axis,
splitting a structure into upper (superior) and lower (inferior) sections.
Question 14
The stomach, liver, and intestines are safely contained inside which major body cavity?
A) Dorsal cavity
B) Vertebral cavity
C) Abdominal cavity
D) Thoracic cavity
Rationale: The ventral cavity houses visceral organs. Its inferior division below the
diaphragm is the abdominopelvic cavity, with the abdominal sub-cavity holding digestive
organs like the stomach and liver.
