SOPHIA HUMAN BIOLOGY [Document title]
1 — Cardiovascular System
Understand the system of blood vessels.
What vessels carry blood away from the heart?
a.) Veins
b.) Atria
c.) Arteries
d.) Venules
2 — Heart and Blood Flow
Identify the major structures of the heart and the specific role in the overall functioning of the
heart.
Which of the following describes the atrium?
a.) The thick wall that divides the heart in half
b.) The upper chamber of each half of the heart
c.) The lower chamber of each half of the heart
d.) The valve that separates the upper and lower chambers of the right half of the heart
3 — Cardiac Cycle and Cardiac Conduction System
Determine the components of the cardiac cycle.
What is the role of the SA node in the heart?
a.) It causes the chambers of the heart to relax after a contraction.
b.) It produces two electric signals: First for the atria to contract and second for the ventricles
to contract.
c.) It slows down the electric signal to the ventricles so they beat after the atria.
d.) It originates the electric signal that causes the heart to beat.
4 — Blood Pressure
Understand how blood pressure is measured and regulated, as well as common disorders.
What kind of blood pressure exists during a contraction of the ventricle?
a.) Hypertension
b.) Systolic
c.) Diastolic
d.) Hypotension
