question 38

Multiple Choice

• A) 8.0 V - I₁R₁ + I₃R₃ = 0
• B) 8.0 V - I₁R₁ - I₃R₃ = 0
• C) 8.0 V + I₁R₁ + I₃R₃ = 0
• D) -8.0 V - I₁R₁ + I₃R₃ = 0

Definitions:

Murmur

A sound, typically an abnormal one, heard in the heartbeat due to turbulent blood flow within the heart.

Capillaries

The smallest blood vessels in the body, connecting arterioles and venules, and facilitating the exchange of water, oxygen, carbon dioxide, and many other nutrients and waste substances between blood and surrounding tissues.

Arterioles

Small branches of arteries that lead into capillaries, controlling blood flow through the regulation of resistance.

Venules

Small vessels that collect blood from the capillaries and join to form veins, playing a role in returning deoxygenated blood back to the heart.
