How does human circulatory system work​

Answer 1

Answer:

Human Circulatory System

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 diagrams.

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).

Answer 2

Step-by-step explanation:

The circulatory system, also known as the cardiovascular system, is a vast network of organs and blood vessels that acts both as a delivery and waste removal system for the body. Nutrients, oxygen and hormones are delivered to every cell and as these necessities are provided, waste products such as carbon dioxide are removed, according to the nonprofit Nemours Children's Health System. Not only does the circulatory system keep our cells healthy, but it also keeps us alive. The heart constantly receives signals from the rest of the body that direct how hard it needs to pump to properly supply the body with what it needs, according to Nemours. For example, when asleep, the body sends electrical signals to the heart that tell it to slow down. When participating in heavy exercise, the heart receives the message to pump harder to deliver extra oxygen to the muscles
