Questions
QUESTION 1 OF 36
_______________ is a type of fluid connective tissue that circulates throughout the
body, carrying substances to and away from bodily tissues.
Correct Answer: Blood
Rationale: Blood is classified as a fluid connective tissue within the body's systems. Its primary function involves
circulating throughout the vasculature to transport vital substances like oxygen and nutrients to tissues, and to remove
metabolic wastes. This circulatory role defines blood's place in the cardiovascular system.
QUESTION 2 OF 36
Blood consists of three types of formed elements, an extracellular matrix called
________, _________________, __________________, &
_____________________.
Correct Answer: Blood consists of three types of formed elements, an extracellular matrix called plasma,
molecules, cell fragments, and debris.
Rationale: Plasma is the extracellular matrix of blood, serving as the liquid component in which formed elements are
suspended. This fluid matrix contains dissolved molecules, such as proteins and electrolytes, along with cell fragments
like platelets and cellular debris. These components collectively facilitate blood's transport, regulatory, and protective
functions. This aligns with Blood consists of three types of formed elements, an extracellular matrix called plasma and
and debris..
QUESTION 3 OF 36
Participate in gas exchange, primarily with oxygen and carbon dioxide
Correct Answer: Red Blood Cells
Rationale: Red blood cells, also known as erythrocytes, contain hemoglobin, a protein that binds to oxygen in the
lungs and transports it to tissues. They also facilitate the transport of carbon dioxide from tissues back to the lungs for
exhalation. This primary function directly aligns with participating in gas exchange.

, QUESTION 4 OF 36
Protect the body from foreign substances by eliciting an immune response
Correct Answer: White Blood Cells
Rationale: White blood cells, also known as leukocytes, are the primary components of the immune system
responsible for defending the body against pathogens and foreign invaders. They identify and neutralize threats
through various mechanisms, including phagocytosis and antibody production. Therefore, their role in eliciting an
immune response to protect against foreign substances makes "White Blood Cells" the correct answer.
QUESTION 5 OF 36
Aid in blood clotting and wound healing
Correct Answer: Platelets
Rationale: Platelets, also known as thrombocytes, are small, anucleated cell fragments that circulate in the blood.
Their primary function involves hemostasis, which includes aggregation at sites of vascular injury to form a plug and
aiding in the release of factors that promote blood clotting and wound healing. This role makes platelets critical
components of the cardiovascular system's response to injury.
