THE CIRCULATORY SYSTEM
By: Jacob, Clarice , Victor , and Lilia
The Circulatory System’s Job
The Circulatory System job is
transporting nutrients, water and oxygen
throughout the entire body/cells. It carries
away wastes such as carbon dioxide that body
cells produce. It is an amazing network of blood
vessels (capillaries, arteries and veins) that
travels through your entire body connecting all
your body cells.
Red blood cells
Red blood cells, also called erythrocytes, are the most
abundant (existing or available in large quantities) cell
type in the blood . Other major blood components
include plasma, white blood cells, and platelets. The
primary function of red blood cells is to transport oxygen
to body cells and deliver carbon dioxide to the lungs . A
red blood cell has what is known as a biconcave shape.
Both sides of the cell's surface curve inward like the
inside of a sphere. This shape helps a red blood cell
maneuver through blood vessels to deliver oxygen to
organs and tissues.
White Blood Cells
White blood cells is a blood component that
protects the body from infectious agents. Also,
they called leukocytes. White blood cells play an
important role in the immune system by
identifying, destroying, and removing
pathogens(something that can cause disease),
damaged cells, cancerous cells, and foreign
matter from the body. White blood cells come
from bone marrow stem cells and circulate in
blood and lymph fluid. White blood cells are able
to leave blood vessels to migrate to body tissues.
The left side of heart
The left side of the heart gets the oxygen-rich
blood from the lungs and pumps it to the body. The
heart has four chambers (two for each side of heart)
and four valves. The two chambers in the left side of
the heart are the left atrium and the right ventricle.
The heart is connected to various blood vessels.
Arteries
An artery is an elastic blood vessel that transports
blood away from the heart to the capillaries.
Pulmonary arteries carries blood from the heart to the
lungs where the blood picks up oxygen. Systemic
arteries deliver blood to the rest of the body. The aorta
is the main systemic artery. It goes from the heart and
branches out into smaller arteries.
Capillaries
A capillary is a very small blood vessel located
in the tissues of the body that gives blood from
arteries to veins . Most capillaries are in tissues and
organs that are working and active.
Capillaries are so small that red blood cells
can only travel through them in single file.
Capillaries measure in size from about 5-10 microns
in diameter.
Veins
A vein is an other elastic blood vessel that
transports blood from various regions of the
body to the heart. Veins can be categorized into
four main types: pulmonary, systemic,
superficial, and deep veins.
Pulmonary veins carry oxygen-rich blood from
the lungs to the left atrium of the heart.
Systemic veins return deoxygenated blood
from the rest of the body to the right atrium of
the heart.
The right side of the heart
The right side of the heart pumps blood to
the lungs to pick up oxygen and drop off waste
such as carbon dioxide. The two chambers in
the right side of the heart are the right atrium
and the right ventricle.
Interesting Facts
Red blood cells live 100-120 days.
The aorta is the largest artery in the body.
Big bodies have slower heart rates.
Human blood comes in different colors, but
not blue.
With a tiny droplet of blood 5 MILLION red
blood cells are found.
Common Diseases in the
Circulatory System
1. Arteriosclerosis is caused by fat build up that
stiffens vessels and stop blood flow.
2. Hypertension is high blood pressure that
presses against the artery wall.
3. Aortic Aneurysm occurs when a section of the
aorta stretches or swells.
4.Heart disease occurs when the blood vessels
that supplies oxygen narrow and stiffen.
5. Varicose veins occurs when veins twist and
swell.
Systems linked with the
circulatory system…
The respiratory system- The respiratory system collects
oxygen in the lungs so the red blood cells can carry it to the
the cells in the body. Also, blood cells drop off carbon
dioxide to be exhaled. The respiratory system wouldn’t have
any thing to do if the circulatory system didn’t work.
The digestive system- In the small intestines, the nutrients
are absorbed. The nutrients go into the blood stream and is
then, transported around the body. If the circulatory system
didn’t work, the nutrients from food can’t go anywhere.
★Note: if the circulatory system didn’t work, the cells won’t
get nutrients…
