Definition
Anatomy and Physiology
Division or components of the circulatory system :1- Cardio-vascular system ( heart , blood and blood
vessels ).
The cardiovascular , or blood circulation , division may
further be divided into cardio ( circulation within the
heart ) and vascular (blood vessels ) components .
The vascular or vessel components is divided into
the pulmonary ( heart to lungs and back ) and
the general , or systemic system ( throughout the
body ).
2- Lymphatic system ( lymph , lymphatic vessels and
lymphatic nodes ) .
Cardio-vascular system
THE HEART :The major organ , functions as a pump to maintain
circulation of blood throughout the body . Anatomically
lies within the mediastinum and rests on the diaphragm ,
it divided into four chambers :1234-
The right atrium
The right ventricle
The left atrium
The left ventricle
Superior and inferior Venae cavae ( veins) carries
deoxygenated blood from all body parts to the right
atrium ,then to the right ventricle through tricuspid
valve ( when right atrium contract ) it pumps it through
pulmonary valve to left pulmonary arteries ( only the
arteries in the body which carries deoxygenated blood ).
Oxygenated blood from the lungs returns to
the left atrium through pulmonary veins
( only the veins in the body which carries
oxygenated blood ) , then through mitral
valve to the left ventricle ( when left atrium
contract )
Vascular components :Network of blood
vessels that carry blood from the heart to the
tissues and back .
Cerebral Arteries :1- Right common carotid artery
2- Right vertebral artery(Anterior).
3- Left common carotid artery
4- Left vertebral artery (Posterior ).
Radiographic examination of the neck vessels
and entire brain circulation is referred to as a
( four- vessels angiogram)
Branches of aortic arch :1- Brachiocephalic artery
2- Left subclavian artery
3- Left common carotid artery
Systemic circulation
Arteries :Transport oxygenated blood from the heart to the
tissues ( large when exit heart then becoming
smaller when devised away from it ) and the
smaller arteries is called arterioles the known as
capillaries within the tissues .
Veins :Transporting deoxygenated blood from the tissues to
the heart . ( From venous capillaries to veins and
become larger near the heart ) .
Pulmonary circulation
From the heart to the lungs and then return
back – Pulmonary artery carry deoxygenated blood
and Pulmonary veins carry oxygenated blood .
Superior and inferior venae cavae (singular vena
cava ) empty blood in right atrium– right ventricle
pump the blood through Pulmonary artery to the
lung .
The oxygenated blood then returns to the heart
through pulmonary veins to the left atrium .
Function of Cardio-vascular system
1- Transportation of oxygen , nutrients , hormones
and chemicals necessary for normal body activity.
2- Removal of waste products through the kidneys
and lungs .
3- Defense and maintenance of body temperature
and water and electrolyte balance , these functions
are performed by the following blood components :
red blood cells , white blood cells and platelet ,
suspended in plasma .
