Which structure separates the right and left sides
of the heart?
a. Septum
b. Valve
c. Myocardium
,d. Endocardium
a. Septum
Explanation: The septum divides the heart into two
halves, ensuring oxygenated and deoxygenated blood
remain separate.
Which blood vessels carry blood away from the
heart?
a. Veins
b. Arteries
c. Capillaries
d. Venules
b. Arteries
Explanation: Arteries transport blood away from the
heart under high pressure; veins return blood back to
the heart.
Which of the following correctly pairs circulation
with its function?
a. Pulmonary – carries blood to and from the lungs
,b. Systemic – sends blood to the lungs only
c. Pulmonary – supplies the body’s tissues
d. Systemic – only involves veins
a. Pulmonary – carries blood to and from the lungs
Explanation: Pulmonary circulation exchanges gases in
the lungs, while systemic circulation delivers oxygen to
tissues.
Which of the following is NOT transported to body
tissues by the blood?
a. Nutrients
b. Oxygen
c. Water
d. Carbon dioxide
d. Carbon dioxide
Explanation: Carbon dioxide is transported away from
tissues as waste, not to them.
True or False: Veins always lead to the heart.
a. True
, b. False
a. True
Explanation: Veins carry blood toward the heart
regardless of oxygen content (e.g., pulmonary veins
carry oxygenated blood).
What causes pressure to decrease as blood flows
through vessels?
a. Increased viscosity
b. Frictional resistance
c. Elastic recoil
d. Increased flow rate
b. Frictional resistance
Explanation: Friction between blood and vessel walls
causes energy loss, reducing pressure downstream.
Hydrostatic pressure is best defined as:
a. Pressure due to fluid in motion
b. Pressure exerted by a static fluid in all
directions
