Transcript of Circulatory system -...
1) The left side of the heart contains oxygenated blood whereas the right side
has de-oxygenated blood.
2) One drop of blood has about 5 million red blood cells and 12 thousand
white blood cells.
3) The heartbeats about 30 million times in 365 days.
4) 10 million blood cells die in the human body every second, the same
quantity is produced at the same time.
5) Blood circulates the entire body in 20 seconds.
6) An average heart pumps about 450 gallons of blood everyday.
7) One of the surprising circulatory system facts is that the heartbeat is the
sound of the valves opening and closing.
8) An average adult's body has about 5 liters of blood in it and a baby's body
has about 1 liter of blood in it.
9) A human heart is a muscle which is the size of a clenched fist.
10) Blood cells die in every 4 months.
11) The plasma in the blood is made in the liver.
12) One of the amazing facts of circulatory system is that the heart
continues to beat even when it is taken out of the body!
The main function of the circulatory
system is to provide nutrients and
oxygen to the various parts of the body,
via the blood, which is circulated through
the veins and arteries. Arteries carry the
oxygenated blood from the heart to the
cells and tissues, whereas veins return
the oxygen-depleted blood from the cells
to the heart. The circulatory system can
be classified into the following two
categories:
The circulatory system consists of the heart, blood vessels and blood. Blood vessels encompasses arteries, arterioles, veins and capillaries. All these parts play a major role in the normal functioning of the circulatory or cardiovascular system. The basic structure of the circulatory system can be considered as a closed loop that starts and finishes at the heart. For better understanding of the circulatory system, let's have a discussion about the heart.
HEART HEART RED BLOOD CELLS WHITE BLOOD CELLS
Heart: The human heart is divided into four
chambers - left atrium, left ventricle, right
atrium and right ventricle. The ventricle
walls are thicker and stronger as compared
to the atria walls. The right atrium is the
upper and right chamber that receives
deoxygenated blood via the superior vena
cava (for upper body) and inferior vena
cava (for lower body). The left atrium
collects the oxygenated blood from the
pulmonary veins and is pumped into the
aorta (biggest artery of the heart), to be
distributed to arteries and arterioles.
Chorus Taking blood from the heart to the cells and back Dealing with all things vascular and cardiac Capillaries, arteries, and veins All I‟m saying is circulation is the name of the game Verse I Now let me start from the heart, ‟cause that seems smart It‟s not hard to see that it‟s the most important part The first step is to gather up oxygen Sends blood to the lungs, back to the heart again Next up, we‟ll talk about the arteries They take blood from the heart to where it‟s gotta be The biggest artery, the main transporter Right next to the heart, it‟s called the aorta
Chorus Verse II From the arteries into the capillaries All your organs and muscles become the beneficiaries Of all the oxygen and nutrients they bring through Very tiny vessels inside the body tissue And now the oxygen‟s gone But first we have some carbon dioxide waste to take on Then it‟s into the veins, and back to the heart again And let the whole cycle start again
Chorus: system‟s called circulatory
nourishing cells is the gist of this story
heart pumps blood, takes oxygen we breathe
with nutrients to the cell it feeds
similar cells come together to form tissues
different tissues join so you won‟t have any issues
organs work together to maintain life function
gonna rhyme about a system at this juncture
how do you transport nutrients to the cell
or take away waste, this I‟m gonna tell
fluid transports smooth so that there‟s no flood
it‟s the circulatory system, uses a tissue called blood
blood‟s make of plasma which is mostly water aight
suspends 2 types of cells, red blood cells and white
RBC‟s contain hemoglobin carries O2
to every cell that make up me and you
Chorus
white blood cells defend us, could be a phagocyte
eats them germs attacked by lymphocytes
lymphocytes produce antibodies that surround
bacteria or a virus, phagocyte gulps „em down
3 kinds of blood vessels so flow is maintained
capillaries arteries and veins
veins take blood to the heart, arteries away
if you can‟t remember this think away = “a”
capillaries are microscopic, thickness of one cell
branch from arteries, keeps your tissues well
brings O2 and nutrients, takes away waste
CO2 released once O2 is displaced
process is called blood oxygenation
happens to every human from every nation
reason why we need to breathe all the time cant you see
aerobic organisms use it for energy
Chorus
blood flows through the veins and on to the heart
a 4 chambered pump, it‟s the most important part
blood enters right atrium from the vena cava
flows into right ventricle just like lava
right ventricle pumps to the lungs blood goes gets more O2 then back to the heart it flows
through left atrium to the most muscular part
left ventricle pumps oxygenated blood to all your body parts
through the aorta a blood vessel baller
the largest artery then branches into smaller
down to capillaries drops off O2 you see
cycle then repeats automatically
now you know the function of your blood and your heart
it’s so beautiful, not a science but an art
stay healthy, heart disease is killer #1
eat lots of raw veggies and exercise, son
