Heart Anatomy Quiz – Learn The Anatomy Of The Heart By Number

The anatomy of the heart consists of

Answer: Tricuspid valve


The valve between the L atrium and the L ventricle is the



Answer: Bicuspid valve AKA mitral valve


Valves that divide the atrium from the ventricles on R & L of heart are known as


Answer: Atrioventricular valves


Why are the heart valves one-way


Answer: to keep the blood flowing in one direction


What type of valve is named because they look like half moons. And what are the names of the 2 in your heart


Answer: semilunar valve Semi (half) lunar (moon) pulmonary and aortic semilunar valves


transports blood back to the heart


Answer: Vena cava


returns blood from the head, arms and upper body to heart


Answer: Superior vena cava


returns blood from the lower legs and body to heart


Answer: Inferior vena cava


when the heart contracts the R ventricle pumps deoxygenated blood to the lungs via this artery


Answer: Pulmonary artery


transports oxygenated blood from the lungs back to the heart via L atrium


Answer: Pulmonary veins


The largest artery in the body. It transports oxygenated blood to entire body. T


Answer: Aorta


The first of the arteries to branch off of the aorta is


Answer: coronary arteries


Trace a drop of blood through the heart to the lungs


Answer: Enters via the vena cava to R atrium -Thru the tricuspid valve -Into R ventricle -Thru pulmonary valve -To pulmonary arteries to lungs -There are tiny capillaries and thin walls so O2 and CO2 can pass over through Osmosis


Trace a drop of blood from the lungs through the heart to the body


Answer: Blood now has oxygen -Thru pulmonary veins -Into L atrium -Past Mitral (bicuspid ) valve -Into L ventricle -Out the aorta (largest artery in the body) -The aorta after descending past the diaphragm is known as the abdominal aorta


Three types of circulation


Answer: Pulmonary – between the heart and lungs-Systemic – between the heart and body-Coronary – the hearts blood supply


The portion of the cardiovascular system which carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.


Answer: Systemic circulation



Refers to the movement of blood through the tissues of the heart


Answer: Coronary circulation


Each beat of the heart has two phases that indicate contraction and relaxation periods what are the two phases and what cycle do they make up


Answer: Relaxation phase – Diastole

Conduction Phase – Systole

-These 2 phases together make up the cardiac cycle.


What happens during diastole


Answer: Blood from the body returns to the heart via vena cavas.

R atrium fills with blood and contracts, pushing open the tricuspid valve (this allows blood to flow into the R ventricle).

At the same time, blood returns from the lungs via the pulmonary veins into the L atrium . (blood fills L atrium prior to atrial contraction).

Atrial contraction forces mitral valve to open to allow blood to flow into L ventricle.


What happens during Systole


Answer: Heart muscles contract, creating pressure to open the pulmonary and aortic valves.

Blood from R ventricle is pushed into the lungs to exchange O2 and CO2.

Blood from the L ventricle is pushed thru the aorta to be distributed throughout the body.


In general women have faster heartbeats then men true or false


Answer: True


Children’s rates are faster then adults true or false


Answer: True


On average adults heart beats


Answer: 60-100 bpm


what sound is heard during systolic phase by the contraction of the ventricles and the closing of the AV valves


Answer: Lubb sound


during the diastolic phase. It is a shorter sound and occurs during the beginning of ventricular relaxation. Caused by the closing of the semilunar valves.


Answer: Dubb sound


Each contraction of heart is caused by


Answer: electrical impulses throughout the heart


The pumping cycle of heart is controlled by


Answer: electrical impulses


______ _______are initiated and transmitted through the heart in a specific pathway.


Answer: Electrical impulses


What do Specialized masses of tissues in the heart do


Answer: They produce electrical impulses and form the conduction system


The conduction system is necessary


Answer: for the heart to pump continuously and rhythmically.


ability of the heart to initiate an electrical Impulse without being stimulated by another source


Answer: Automaticity


Ability of the heart muscle cells receive and transmit an electrical impulse


Answer: Conductivity


Ability of the heart muscle cells to shorten in response to an electrical stimulus


Answer: Contractility


Ability of the heart muscle cells to respond to an impulse or stimulus. Without this quality the heart would nor react to the electrical impulses that are initiated within the heart


Answer: Excitability


Where is the SA node located


in upper portion of the R atrium


What is the SA node also known as? /why?


AKA pacemaker of the heart – it initiates the heartbeat


Automatricity of the fibers of SA node produces


the contraction of the R and L atria


SA node fires about


60 – 100 times per minute


Where is the AV node located


Answer: on the floor of the R atrium


Impulses travel from the SA node à


Answer: AV node because of conductivity


The AV node itself causes a delay (slowdown) of the impulse two reasons why


Answer: 1) to allow additional blood to travel from the atrium to the ventricles before they contract (known as atrial kick)

this will increase the cardiac output (the amount of blood pumped out of the heart into the rest of the body)

2) reduces the number of electrical impulses transmitted onto the ventricles,

this is important if the SA node is firing too fast


What is located next to the AV node – Provides transfer of electrical impulses from atria to the ventricles


Answer: Bundle of HIS


What is located on the L and R side of the interventricular septum- Impulses travel R and L bundle branches to the R and L ventricles Electrical impulse split and travel down both sides. This activates the myocardium to contract.


Answer: Bundle branches


What Speeds impulses thru the ventricles provides an electrical pathway for each of the cardiac cells. The electrical impulses accelerate and activate the L and R ventricle at the same time to contract.


Answer: Purkinje fibers
