There are three different types of circulation that occur regularly in the body:
- Pulmonary circulation. This part of the cycle carries oxygen-depleted blood away from the heart, to the lungs, and back to the heart.
- Systemic circulation. This is the part that carries oxygenated blood away from the heart and to other parts of the body.
- Coronary circulation. ...
- Heart, a muscular organ that pumps blood throughout your body.
- Blood vessels, which include your arteries, veins and capillaries.
- Blood, made up of red and white blood cells, plasma and platelets.
What are the five components of the circulatory system?
- Red blood cells: 99% of blood cells are of this type, which are also known as erythrocytes. ...
- Platelets Also known as thrombocytes, they are the smallest blood cells. ...
- White blood cells Also known as leukocytes, white blood cells are the mainstay of the immune system. ...

What are three things make up the circulatory system?
There are three main types of blood vessels:
- Arteries: Arteries are thin, muscular tubes that carry oxygenated blood away from the heart and to every part of your body. The aorta is the body’s largest artery. ...
- Veins: These blood vessels return oxygen-depleted blood to the heart. ...
- Capillaries: These blood vessels connect very small arteries (arterioles) and veins (venules). ...
What are the parts of circulatory system and their function?
Circulatory system diagrams are visual representations of the circulatory system, also referred to as the cardiovascular system. It is comprised of three parts: the pulmonary circulation, coronary circulation, and systemic circulation. The main function of the circulatory system is to circulate blood, which carries oxygen and nutrients ...
What is the most important part in the circulatory system?
- The circulatory system delivers oxygen and nutrients to cells and takes away wastes.
- The heart pumps oxygenated and deoxygenated blood on different sides.
- The types of blood vessels include arteries, capillaries and veins.
What are the main parts of the circulatory system?
Follow Us: The three main parts of the circulatory system are the heart, the blood and the blood vessels. The purpose of the circulatory system is to transport oxygen throughout the body. In humans, the heart is a fist-sized muscle located slightly to the left of center in the chest.
What are the two parts of blood?
Blood is made of two parts: plasma and blood corpuscles (or cells). Plasma is the liquid portion of blood and is made mostly of water. There are three types of corpuscles: red blood cells, white blood cells and platelets.
Why do capillaries have thinner walls than arteries?
Capillaries are tiny vessels that connect arteries to veins. Because their walls are so thin, they allow oxygen and other nutrients to pass from the vessels to the surrounding tissue.
Which artery carries oxygenated blood away from the heart and to the tissues?
Arteries carry oxygenated blood away from the heart and to the tissues. The one exception to this is the pulmonary artery, which carries deoxygenated blood from the heart to the lungs. They are thick-walled, elastic vessels that contain no valves.
How many times does the heart beat?
It acts as an engine for the circulatory system, pumping blood through the blood vessels. It will beat approximately three billion times in an average human lifespan. The blood vessels are hollow tubes that conduct blood from the heart to the body’s tissues and back again. There are three types: arteries, veins and capillaries.

Which part of the circulatory system is responsible for oxygenating blood?
Pulmonary circulation is the portion of your circulatory system responsible for oxygenating your blood via your lungs. Cardiac circulation is responsible for supplying your heart muscle with oxygen rich blood while your systemic circulation supplies the rest to the systems in your body.
What organs do the body pump blood to?
In this process, your body pumps blood to all of your skeletal muscles (from your fingers to your toes), most of the organs in your body (including your brain, stomach, intestines, and), and all of the connective tissues of your body ( like your bone, tendons, ligaments, and even fat). So, as you can see, it's a pretty important job.
What color are pulmonary veins?
Now, just like pulmonary arteries are always color coded blue, pulmonary veins are always red, oxygen rich. It's important to note what the color coding system actually means because all too often people assume that all arteries are color coded red while all veins are color coded blue, and that can lead to a lot of confusion in pulmonary ...
How does oxygen deficient blood return to the heart?
So, blood returns back to the heart via your venous route and enters into the right chambers of your heart.
What is the role of circulation?
The role of your entire circulation system is to oxygenate your blood and make sure that it is sent to all of the cells of your body. But the three different types of circulation are responsible for pumping that blood to different target organs and areas of your body. So with that said, let's jump right in and learn how these types ...
Which arteries pull blood from the heart?
Now, what's interesting to note is that your heart is kind of a selfish organ and so it has two vessels, called the right and left coronary arteries, that pull oxygen rich blood from the systemic circulation system before it even has a chance to enter the aorta, which is the major artery that stems from the heart.
Does the heart need its own system?
It needs its own system of arteries and veins.
Systemic Circulation
Systemic circulation involves the blood flow from the heart to the body tissues and from the body tissues back again into the heart. The blood that goes towards the tissues is oxygenated, while the blood coming back into the heart is deoxygenated. A blood vessel known as the aorta transports the oxygenated blood from the heart to the body tissues.
Pulmonary Circulation
Pulmonary circulation involves blood flow from the heart into the lungs and then back into the heart. The blood that flows from the heart into the lungs is usually deoxygenated, while the blood flowing back from the lungs into the heart is oxygenated.
Cardiac Circulation
Cardiac circulation supplies blood to the heart muscle. It involves both the arterial flow and the venous flow and is responsible for providing the heart muscle cells with oxygenated blood and carrying away unoxygenated blood. Cardiac circulation is associated with two main vessels: the right and the left coronary arteries.
Overview
Your heart and blood vessels make up the circulatory system. The main function of the circulatory system is to provide oxygen, nutrients and hormones to muscles, tissues and organs throughout your body. Another part of the circulatory system is to remove waste from cells and organs so your body can dispose of it.
Function
The circulatory system’s function is to move blood throughout the body. This blood circulation keeps organs, muscles and tissues healthy and working to keep you alive.
Conditions and Disorders
Many conditions can affect the health of your circulatory system, including:
Frequently Asked Questions
Your body has more than 60,000 miles of blood vessels that circulate about 1.5 gallons of blood every day.
What is the function of the circulatory system?
These materials are known as metabolic wastes or waste products of the cell. The transport of needed materials to the cells and waste materials from the cells is the function of the circulatory system.
What are the three types of blood vessels?
1. Vascular System. The system of tubes, or vascular system, through which blood flows consists of three types of blood vessels. Those that bring blood from the heart (arteries), those very fine tubes into which an artery branches (capillaries), and those that bring blood back to the heart (veins).
What happens when the left ventricle contracts?
When the wall of the left ventricle contracts, blood rushes to all parts of the body. The right ventricle pumps blood to the lungs, passing through the pulmonary arteries. As the blood reaches the capillaries of the lungs, oxygen diffuses into the blood, while excess carbon dioxide leaves the bloodstream.
How does blood travel in a vertebrate body?
The diagram shows how blood travels in the body of a vertebrate - it leaves the heart by way of an artery, enters an organ through a network of capillaries, and returns to the heart by way of a vein. Substances dissolved in the blood simply diffuse from thin-walled capillaries to the nearby cells.
What is the name of the chambers of the heart?
Hence, they are referred to as the receiving chambers of the heart. The ventricles pump blood to the different parts of the body. They are referred to as the pumping chambers of the heart.
Where does blood go when it leaves the body?
The blood leaves the left ventricle by way of the largest blood vessels in the body, aorta. As the blood reaches the capillaries of the different organs of the body, oxygen, food, and other substances diffuse out of the blood and into the tissues.
Why does blood flow in one direction?
Blood flows in this direction and not backward because of the presence of the flaps of muscles (valves), which allow blood to flow in one direction only. 2a. Pulmonary and Systemic Circulation of Blood. Blood from all over the body enters the heart by way of blood vessels that open into the right atrium.
