Question

What is the bundle of His?

A. a collection of heart muscle components that specialize in preventing the backward flow of blood

B. a collection of valves used for electrical conduction that allow the blood vessels to contract

C. a collection of heart muscle components specializing in electrical conduction that allow the ventricles to contract

D. a collection of chambers specialized for electrical conduction that allow the ventricles to expand


Answer: C

Answer 1

Option C is the right answer

Step-by-step explanation:

A group of heart muscles that specialize in conducting electric to transfer this impulses to the apex point of fascicular branches from the AV node, is known as HIS bundles. It is located in the "right and left branches" in the interventricular septum.

The filament fibres produced by the branches transports the impulse to the muscles of ventricular to make it contract. It takes a time period of 0.03-0.04 seconds for the impulses to flow to the ventricular.

Answer 2

C

Step-by-step explanation:

The blunde of His is an agruppation of neurons that are localized on the ventrical walls of the heart. It's mision is to transmit the nervous signals that come from the sinoatrial node that is located on the left atria of the heart, to the muscles that form the vertix of this organ, making them contract.

The answer is C: a collection of heart muscle component specializing in electrical conduction that allow the ventricles to contract.
