Question

The study of blood vessels is termed as
(1) Angiology
(2) Cardiology
(3) Haematology
(4) HIstology

Answer 1

Hint: Blood vessel in the human or animal body is a vessel in which blood circulates. The vessels that carry blood away from the heart are called arteries while the vessels, which return the blood to the heart, are called veins.

Complete step by step answer:
Angiology is the study of blood vessels. It is related to the study of the diseases of the circulatory system and the lymphatic system, i.e., arteries, veins and lymphatic vases, and its diseases. In humans, several diseases and conditions such as inflammation, atherosclerosis, etc. can affect the structure and function of blood vessels. It involves the deposition of fat in the arterial endothelium in which narrowing of the arterioles causes an abnormal increase in blood pressure.
- The very small branches of arteries are known as arterioles.
- The small branches called venules collect the blood from various organs and unite to form a vein.
- Vessels that connect the arterioles and venules are minute thin- walled called capillaries. The capillaries act as a medium for the exchange of nutrients and waste between the blood and body tissue.
- In human physiology, the artery, with one exception, carries oxygenated blood and nourishment from the heart to the tissues of the body.
- In human physiology, the vein, with four exceptions, carries oxygen- depleted blood to the right upper chamber (atrium) of the heart.
- A thin layer of cells known as the endothelium, lines the inner surface of every blood vessel. The endothelium performs the function of controlling the passage of substances, including nutrients and waste products, to and from the blood.
So, the correct answer is, ‘(a) Angiology.’

Note:
- Angiogenesis is a process of the regeneration of tissues, which forms blood vessels only under certain circumstances.
- Angiogenesis may play an important role in the replacement of damaged tissue but these are also observed to occur under other abnormal conditions, such as tumor growth and progression.
