who can explain me full human circulatory system in Hindi for 7th
Answers
Answer:
The human body is a complex machine, requiring many processes to function efficiently. To keep these crucial processes running without any hitches, vital elements and components need to be delivered to the various parts of the body.
This role of transportation is undertaken by the human circulatory system, moving essential nutrients and minerals throughout the body and metabolic waste products away from the body. Below is the neat labelled Circulatory system diagram.

Human Circulatory System
The human circulatory system consists of a network of arteries, veins, and capillaries, with the heart pumping blood through it. Its primary role is to provide essential nutrients, minerals, and hormones to various parts of the body. Alternatively, the circulatory system is also responsible for collecting metabolic waste and toxins from the cells and tissues to be purified or expelled from the body.
Features of Circulatory System
The crucial features of human circulatory 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 is 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).
Organs of Circulatory System
The human circulatory system comprises 4 main organs that have specific roles and functions. The vital circulatory system organs include:
Heart
Blood (technically, blood is considered a tissue and not an organ)
Blood Vessels
Lymphatic system
Heart
The heart is a muscular organ located in the chest cavity, right between the lungs. It is positioned slightly towards the left in the thoracic region and is enveloped by the pericardium. The human heart is separated into four chambers; namely, two upper chambers called atria (singular: atrium), and two lower chambers called ventricles.

Though other animals possess a heart, the way their circulatory system functions is quite different from humans. Moreover, in some cases, the human circulatory system is much more evolved when compared to insects or molluscs.
