Components of vascular system
Cardiovascular system includes heart, arteries, arterioles, capillaries, venules and veins.
What are the different types of circulation?
There are three types of circulation
Systemic circulation
It is responsible for transporting oxygenated blood through arteries to the entire body and then returns deoxygenated blood to the heart via veins. The circulation of blood flow is as follows:
Pulmonary circulation
It consist of that part of circulatory system which pumps deoxygenated blood to the lungs and returns oxygenated blood to the heart. The circulation of blood flow is as follows:
Portal circulation
It is part of systemic circulation. The blood passes through two sets of capillaries, the circulation begins with capillaries and ends with capillaries. The vessel between the two sets of capillaries is known as portal vein. Portal circulation is found at the following sites:
a. Hepatic portal system – between small intestine and liver.
b. Renal portal system – in the kidney.
c. Hypothalamo-hypophyseal system – between hypothalamus and hypophysis cerebri.
d. Suprarenal portal system – between the cortex and medulla of adrenal gland.
