Human Circulatory System

Introduction

The human body is a complex machine, which needs many processes in order to function properly. To keep these important processes running smoothly, essential nutrients and nutrients need to be delivered to different parts of the body.

This role of transport is made up of the human circulatory system, delivering essential nutrients and minerals throughout the body and metabolic waste products away from the body.

The human circulatory system includes a network of arteries, arteries, and capillaries, through which the heart pumps blood. Its main role is to supply 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 cells and tissues for cleansing or excretion.

Circulatory System Features

The key elements of a person’s circulatory system are as follows:

• The human circulatory system includes the blood, heart, blood vessels, and lymph.
• The human circulatory system circulates the blood in two loops (double circulation) – one with oxygen-rich blood, the other with oxygen-deprived blood.
• The human heart has four chambers – two ventricles and two auricles.
• The human circulatory system has a broad body network of blood vessels. These include arteries, veins, and capillaries.
• The main function of the blood vessels is to transport oxygen and nutrients to all parts of the body. It also has the function of collecting metabolic waste that will be excreted from the body.
• Many diagrams of the circulatory system do not show its full length. Theoretically, if the veins, arteries, and capillaries of a person were to extend, eventually to the end, it would take a distance of about 1,00,000 kilometres (or about eight times the diameter of the Earth).

Organs of the Circulatory System

The human circulatory system consists of 4 primary organs that play a role. Key components of the circulatory system 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, between the lungs. It is located slightly to the left of the thoracic region and is covered by the pericardium. The human heart is divided into four chambers; that is, the two upper chambers are called the atria (singular: atrium), and the two lower chambers are called the ventricles.

Although some animals have a heart, the way their circulatory system works is very different from that of humans. In addition, in some cases, the human circulatory system is highly variable in comparison with insects or molluscs.

Double Circulation

The way blood flows in the human body is different, and it also works. Blood circulates in the heart twice, which is why it is called double circulation. Some fish-like animals have a single cycle, where the blood finishes circulating to the whole animal only once.

The great advantage of double circulation is that all tissues in the body have oxygen-rich blood, and are not mixed with deoxygenated blood.

Blood

Blood is the body’s fluid that connects fluids, and it forms an important part of the human circulatory system. Its main function is to transport nutrients, hormones, minerals and other essential nutrients to different parts of the body. Blood flows through a specific set of channels called blood vessels. The organ involved in transfusing blood into various parts of the body is the heart. Blood cells, blood plasma, proteins, and other minerals (such as sodium, potassium and calcium) make up human blood.

Blood is made up of:

Plasma – a component of blood fluid and is made up of 90% water.
Red blood cells, white blood cells, and platelets form a solid component of blood.

Types of Blood Cells

The human body is made up of three types of blood cells, namely:

• Red blood cells (RBCs) / Erythrocyte
  Red blood cells are primarily involved in transporting oxygen, nutrients, and other substances to various parts of the body. These blood cells also release waste products from the body.
• White blood cells (WBC) / Leukocyte
  White blood cells are specialized cells, which serve as the body’s immune system. They provide protection by protecting against germs and harmful microorganisms.
• Platelets / Thrombocyte
  Platelet cells help to form clots and stop bleeding. They act in the area of ​​injury or injury.

Blood vessels

Blood vessels are a network of blood vessels throughout the body. Arteries and veins are the two main types of blood vessels in the circulatory system in the body.

Blood vessels carry oxygen from the heart to various parts of the body. They are thick, stretchy and divided into a small network of blood vessels called capillaries. The only exception is the pulmonary arteries, which carry oxygen-deprived blood to the lungs.

Arteries

Arteries are the blood vessels that carry deoxygenated blood to the heart from various parts of the body. They are small, stretchy and located close to the skin surface. However, the lungs and navel are the only arteries that carry oxygen-rich blood throughout the body.

Lymphatic system

The human circulatory system contains another body fluid called lymph. Also known as tissue fluid. It is produced by a lymphatic system that includes a network of connected organs, nodes and ducts.

Lymph is a colourless liquid that combines salt, protein, water, which transports and circulates digested foods and fats in the tissues. Unlike the circulatory system, the lymph is not pumped; instead, it flows slowly over the ship’s ridge.

Circulatory System Functions

The most important function of the circulatory system is to transport oxygen throughout the body. Some important functions of the human circulatory system are as follows:

• It helps to maintain all the organs of the body.
• It carries blood, nutrients, oxygen, carbon dioxide and hormones throughout the body.
• It protects the cells from germs.
• It acts as a visual connector for cell-to-cell interaction.
• The substances in the blood help repair damaged tissue.

 

The human body has several distinct processes that occur simultaneously. These processes are important for our bodies to take place to keep us alive.

The circulation of blood in the human body is essential for proper oxygen supply to the various cells. This oxygen is then used by our cells for other purposes, including breathing. Breathing is an important process in our human body to perform various life functions.

The human circulatory system is a complex network of arteries, capillaries, and arteries. Our heart is a little like a fist found in our ribs, and it tends to turn left. It is an organ that pumps blood to our bodies.

FAQ’s

How does the human circulatory system work?

The human circulatory system is a network of arteries, arteries, capillaries designed to provide essential minerals, nutrients, and other essential nutrients to various parts of the body. It also collects metabolic waste that will be filtered or excreted from the body.

What are the three types of circulation?

Circulation of the lungs ,System Cycle ,Coronary circulation

Is the human circulatory system open or closed?

The human circulatory system is a closed system that pumps blood through a network of arteries and veins. This type of rotation is seen in all vertebrates and invertebrates.
