It’s Function
The circulatory system functions in the delivery of oxygen, nutrient molecules,
and hormones and the removal of carbon dioxide, ammonia and other
metabolic wastes
The circulatory system works thanks to constant pressure from the heart and
valves throughout the body
The circulatory system is composed of the heart and blood vessels, including
arteries, veins, and capillaries
The Heart
The heart is a muscle located a little bit to the left of your chest
The heart's main function is to pump blood throughout the body
The blood provides the body with oxygen and nutrients that it needs and carries
The right side of your heart receives blood from the
away waste
body and pumps it to your lungs while the left side of
your heart receives blood from the lungs and pumps
it out of the body
The Arteries
Each artery is a muscular tube lined by smooth tissue and has three layers: the
intima, the media, and the adventitia
Arteries carry blood from the your heart to the rest of body
It is conveyed from the heart to all parts of the body
Veins
Veins carry blood back to the heart
They have the same three layers as arteries but are thinner and less flexible
The two main veins are the superior and inferior vein which are located above
and below the heart
Veins contain valves which prevent blood from flowing backwards
Capillaries
Capillaries connect the arteries and veins
They are very important because cells get their nutrients and oxygen from them
They also remove waste products and carbon dioxide
How This Organ System Works With Other Organs
It supplies oxygen and nutrients by working with the respiratory system
The digestive system works very closely with the circulatory system to get the
absorbed nutrients distributed through your body
The circulatory system also carries chemical signals from your endocrine
system that control the speed of digestion
Which Diseases Affect Your Organ System
One of the most common diseases of the system is arteriosclerosis, which
results from the growth of fatty deposits in the arteries
Another disease, hypertension, commonly called high blood pressure, is often
associated with arteriosclerosis
A substance called plaque can build up in the arteries, restricting blood flow
and ultimately stopping or blocking it altogether. This plaque can cause
serious cardiovascular disease that leads to heart attack, stroke, peripheral
artery disease or renal artery disease
