The main components of the transport system in human beings are the heart, blood, and blood vessels.
Given below article gives a detailed description of the components of the heart.
Heart
The heart is located at the centre of the chest and points slightly towards the left. The heart acts as a pump in the circulatory system to push out blood. There are three types of blood vessels in the human body namely, arteries, veins and capillaries. The heart needs valves to regulate the flow of blood. It helps in the movement of blood in a single direction.
Description of Heart
The heart looks simple from the exterior but internally it is the most complex organ in our human body. The various parts of the heart are mentioned below:
The upper parts of the heart called Atria.
The lower parts of the heart called Ventricles.
Capillary tubes are the blood vessels that connect arteries to veins
The right side part of the heart pumps blood into the lungs
The left side part of the heart pumps blood to the entire body, except the lungs
Heartbeat
Heartbeat is the sound produced when there is contraction and relaxation of the heart. At rest, the human heart usually beats 70 to 72 times per minute.
A person’s heart tends to beat faster after running for a while or when a person is strained physically. After, the physical strain the person needs more oxygen. Hence the heart pumps faster.
Transport system
Human circulatory system is responsible for the transport of materials inside the human body. The organs of the circulatory system are heart, arteries, veins and capillaries.
The table given below shows the functions and difference between arteries, veins and capillaries
Arteries
Veins Capillaries
These are tough, thick and comprises of elastic tubes. Veins are thin-walled and comprise of non-elastic tubes. Capillaries are very thin-walled tubes.
They contain a narrow lumen. They contain a wide lumen. Only RBC can pass through lumen.
Blood is carried away from the heart to various organs at high pressure. Blood id transported to the heart from various organs at low pressure. Blood is carried from arteries to veins.
Valves are absent. Valves are present to prevent the backward flow of the blood. Valves are absent.
Transport only oxygenated blood (except for the pulmonary artery). Transport only deoxygenated blood (except for the pulmonary vein). Helps in exchange of oxygen, carbon dioxide, water and salts between the blood and the surrounding tissues.
Circulation of Blood
The human blood circulatory system is composed of the heart, the blood and the blood vessels. The human heart is divided into four chambers. The upper two chambers are called right and left atrium and the lower two chambers are called the right and the left ventricles.
Types of Circulation
Single circulation: A circulatory system in which the blood passes through the heart only once in one complete cycle is known as single circulation. It is commonly seen in fishes.
Double circulation: A circulatory system in which the blood travels twice through the heart in one complete cycle is known as double circulation. It is commonly seen in amphibians, reptiles, birds and mammals.
Circulation of blood throughout the body is an important process. The blood carries oxygen, nutrients and vital ingredients need by our body to the respective tissues and cells. The diagram given below depicts the complete circulation of blood in our body.
