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.

Right ventricle of heart transport low-oxygen blood from pulmonary artery to lungs and
where the through air sacs diffusion takes place and pulmonary veins carry oxygenated blood
from lungs to left atrium. Left atrium transport blood to left ventricle through the passage of
valve and further distributes to several part of body. The deoxygenated blood is transported ot
lungs and through expiration it is expel out.
Vascular system works as the important vital for all other body system as supply of
oxygen, gases and fluid occur in every part of the body through them. In relation to digestive
system, the blood flows through the intestinal capillaries where the formed nutrients or glucose
co-ordinate with blood and its supply are delivered to other parts of the body. In relation to
kidney, blood bring out the waste material to kidney where the filtration takes place and waste
matter is disposed out through urine by the body. Other than it, capillaries or vessels also
maintain the homeostasis while absorbing the heat through the blood and distributing it to other
part of the body.
Essay 4
Facial artery play the significant role in providing the blood to muscles, gland and tissues
in face and mouth. Main artery present in the neck and face of the body is called as facial artery
which his the part of external carotid artery. Carotid artery is the major blood vessels which are
present in neck which supply the blood from the heart to brain, neck or brain part. Body consist
of two types of carotid artery which symbolise as the internal land external. Internal carotid
artery transport the oxygenated blood from the heart to the brain and external arterioles delivers
the oxygen-rich blood to face and neck part of the body. Similar to other arteries, they are also
formed with they are consist of three layers including adventitia the outer layer, media the
muscular layer present in between and the intima which is the inner most layer of the artery.
Main function of the artery is to transport the oxygen-rich fluid, gasses or nutrients to the face or
neck.
Neck artery division primarily consist of 4 parts which includes acending palatine artery,
tonsillar branch, submental artery and glandular artery. Acending Palatine artery supply oxygen-
rich blood to auditory tube and palatine tonsil through the superior pharyngeal constrictor and
soft palate region. Tonsillar branch supply the blood to palatine tonsil which his present in
between the styloglossus and media pterygoid muscles. Submental artery is present in lower part
of chin which is the largest cervical facial artery . It is transport through the submandibular gland

where the mylohyoid muscle and mandible is present. Additionally, glandular branch supply the
blood to sublingual salivary gland and lymph nodes.
Facial artery main role is transport the oxygen and nutrient to various part of the body.
Further the facial artery is divided into several branches which includes inferior labial artery,
superior labial artery, lateral nasal branch and angular artery. Inferior labial artery is present
close towards corner of the mouth where it supplies the oxygen and nutrients to lower lip or
labial glands present near triangularis and it further connects with mental branch. Superior labial
artery is big than inferior which runs along with the upper lip muscles, wing of nose and the
septum. It is considered as more complex branch of the facial artery. Next is lateral nasal branch
is present in the dorsal part of nose which supply nutritions and oxygen to part of nose and eye.
Sidelong it also consist of the angular artery which his endmost facial artery branch who supply
the nutrients to cheek and ophthalmic part of the eye. It is also present in the media angle of the
orbit.
It is symbolize important in the beauty industry as when the oxygen and nutrients don't
transport effectively to the face or neck there is progression of cells towards the damage. Skin
requires the oxygen to promote the moisture in skin as it helps to repair the tissues and cells
regularly. When the supply of oxygen reduce then there is risk of development of wrinkles or
fine-lines in individuals which is result of weak cells in the facial part. Additionally, the
deficiency of vitamins in part of body also affects health of skin. Poor nutrients supply lead to
progression of omega acid deficiency which triggers the skin and hair problem in individuals.
Low oxygen sup[ply of blood can tend to progression of the bluish colour occurrence in the skin.
Facial artery is damages due to drastic supply of radiation which can be control by usage of
mineral based sunscreen. It is recommended for intake of collagen to health of the skin. It is
recommended to have intake of enough water to influence the oxygen level of the body and to
eat rich iron based foods. Regular exercise accelerates the level of supply of oxygen in the body.
