Essay 3
Human vascular system is system which is made up of varied vessels which carry out the
bloods and lymphs through out the body. Vascular are the combination of large unit of blood
vessels and lymph vessels which carry through blood and lymph throughout the body. Vascular
system is also known as the circulatory system of the body which pumps out primarily the co2
rich blood from the heart to lungs to revert the oxygenated blood from the lungs. When
oxygenated blood reaches the heart it furthers carry forwards to others tissues or organs through
varied vessels. Primarily the circulatory system carries nutrients, oxygen and hormones with the
blood to various part of bod including every organ, tissue or cell. Additionally, the vessels
contains the blood which carry through the carbon dioxide with blood which is withdraw out
from the body through expiration process. The lymph vessels caries the lymphatic fluid which is
the clear fluid travels through out the lymphatic system whose function is to protect the body
from forthcoming infections or disease. At the end of the nodes, lymph vessels meet to filter the
lymph. They consist of the mini-valve which make interstitial fluid to flow easily but don't make
them flow out.
The vessels of circulatory system consist of arteries, veins and capillaries. Arteries are
accountable to dispense out oxygenated-rich blood from heart to different organs. They are of
two types the pulmonary and systemic arteries. Pulmonary arteries transport degrade oxygenated
blood from right ventricle of heart to the lungs and systemic arteries diffuse out oxygen-rich
blood from left ventricle to body tissues. Capillaries are tiny blood vessels which have thin walls.
In the capillaries the exchange of nutrients or waste occur and simultaneously the oxygen and
carbon dioxide exchange takes place. They are responsible to yield out the waste products from
different tissues of the body. Blood which is transport out of the heart through systemic arteries
which contains the saturated oxygen in the blood. Further arteries are shatter into tiny vessels to
provide oxygen and nutrients to varied tissues and cells of the body. Veins return the oxygen-
depleted blood vessels to the heart. Their is primarily the two central veins which delivers the
blood to your heart which hare superior vena cava and inferior vena cava. Superior vena cava is
present near arms and head which carries blood form upper body part to heart. Inferior vena cava
is present near stomach, pelvis or legs which also consist of the valves that prevent the blood to
be flowing backwards. They carry blood from lower body to the heart.
