The anatomy of the heart consists of

Chambers, valves, vessels and circulation

The function of the heart is to

circulate blood throughout the lungs and various tissues of the body.

Without the circulation of the heart

nutrients cannot be delivered, waste products cannot be removed, and therefore you would die.

What happens when the heart contracts

blood moves into the lungs to get oxygen, then the oxygen gets into the body’s circulation delivering oxygen to the tissues

Blood supplies the tissues with

nutrients and O2

Blood removes

CO2 and waste products

The heart is what shape organ

triangular shaped

in the center of the chest, under the sternum and in between the lungs. 2/3 rds of the heart lies to the left of the sternum

The size of a fist

The approx weight of the heart is

10.6 oz

Beats average (minutes, Day, lifetime)

72 beats per minute
– 100,000 beats per day
– 22.5 billion in a lifetime

The heart Pumps about ____ ml blood per beat for a total ___L/minute

140 blood per beat for a total 5L/minute

Heart pumps daily about ______ L or ______ gallons of blood (average bathtub filled 36 times)

7250 L or 1800 gallons of blood
average bathtub filled 36 times

The heart is like ____ pumps side by side divided by ________.

2 pumps side by side divided by septum

What are the 4 chambers of the heart

2 upper atria 2 lower ventricles

What keeps blood flowing in one direction

Valves

What prevent the valves from turning inside out

Chodae Tendae

Middle muscular layer

Myocardium

Muscle is thickest in what chamber of the heart

L ventricle

thicker muscle in heart chamber means.

stronger contraction of that chamber giving it the ability to pump blood through body

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

Tricuspid valve

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

Bicuspid valve AKA mitral valve

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

Atrioventricular valves

Why are the heart valves one-way

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

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

transports blood back to the heart

Vena cava

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

Superior vena cava

returns blood from the lower legs and body to heart

Inferior vena cava

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

Pulmonary artery

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

Pulmonary veins

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

Aorta

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

coronary arteries

Trace a drop of blood through the heart to the lungs

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

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

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.

Systemic circulation

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

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

Relaxation phase – Diastole
Conduction Phase – Systole
-These 2 phases together make up the cardiac cycle.

What happens during diastole

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

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

true

Children’s rates are faster then adults true or false

true

On average adults heart beats

60-100 bpm

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

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.

Dubb sound

Each contraction of heart is caused by

electrical impulses throughout the heart

The pumping cycle of heart is controlled by

electrical impulses

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

Electrical impulses

What do Specialized masses of tissues in the heart do

They produce electrical impulses and form the conduction system

The conduction system is necessary

for the heart to pump continuously and rhythmically.

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

Automaticity

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

Conductivity

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

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

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

on the floor of the R atrium

Impulses travel from the SA node à

AV node because of conductivity

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

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

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.

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.

Purkinje fibers
