Question

Explain the features of Human Circulatory system.

Answer 1

Features of Circulatory System
The crucial features of the human circulatory system are as follows:

• The human circulatory system consists of blood, heart, blood vessels, and lymph.
• The human circulatory system circulates blood through two loops (double circulation) – One for oxygenated blood, another for deoxygenated blood.
• The human heart consists of four chambers – two ventricles and two auricles.
• The human circulatory system possesses a body-wide network of blood vessels. These comprise arteries, veins, and capillaries.
• The primary function of blood vessels is to transport oxygenated blood and nutrients to all parts of the body. It is also tasked with collecting metabolic wastes to be expelled from the body.
• Most circulatory system diagrams do not visually represent its sheer length. Theoretically, if the veins, arteries, and capillaries of a human were laid out, end to end, it would span a total distance of 1,00,000 kilometres (or roughly eight times the diameter of the Earth).
