BIOD 151 MODULE 1 EXAM PREP 2026 TESTED
QUESTIONS WITH RATIONALE
◉ 6 levels of organization. Answer: Chemical, cellular, tissue, organ,
organ system, organism
◉ Physiology. Answer: The study of body function
◉ Epithelial tissue. Answer: Covers the body surface and lines the
cavities. Is used for secretion and absorption; cells are constantly
dividing to replace dead ones
◉ Muscle tissue. Answer: A body tissue that contracts or shortens,
making body parts move. 3 types: cardiac, skeletal and smooth
◉ Cardiac muscle tissue. Answer: Striated and involuntary
◉ Skeletal muscle tissue. Answer: Striated and voluntary
◉ Smooth muscle tissue. Answer: Non-striated and involuntary
,◉ Connective tissue. Answer: Supports and protects body organs
(e.g. bones, tendons, blood, + ligaments). Bind tissues and play
supportive role
◉ Nervous tissue. Answer: Communication between the cells of the
body by forming a system of electrical impulses
◉ Integumentary system. Answer: Layers that make up the skin
(epidermis, dermis, hypodermis). Produces vitamin D and contains
the pain and pressure receptors
◉ Epidermis. Answer: Outer layer of skin
◉ Dermis. Answer: Middle layer of skin
◉ Hypodermis. Answer: Inner layer (aka subcutaneous tissue layer).
Mostly fat and anchors the dermis to the fat cells (aka adipocytes)
which help insulate and regulate body temperature
◉ Skeletal system. Answer: Framework for muscular system and
supports body organs. Protection for internal organs, houses blood
cells, and stores minerals
, ◉ Muscular system. Answer: Allows body to move - muscles attach
to bones to bring movement to the skeletal system
◉ Nervous system. Answer: Provides internal communication. Uses
electrical impulses to communicate within the body and allows body
to respond to internal and external environments
◉ Digestive system. Answer: Breaks down food into small molecules
which then enter the bloodstream through the small intestine and
supply the body with nutrients
◉ Endocrine system. Answer: Made of glands which make hormones
to regulate the reproductive system and metabolism of the body
◉ Metabolism. Answer: All of the chemical reactions that take place
in the body that enable us to function
◉ Catabolism. Answer: Breakdown of substances into their simpler
building blocks
◉ Anabolism. Answer: Synthesizing of more complex structures
from simpler ones
