The circulatory system controls the steady circulation of the blood through the body by means of heart and blood vessels. It is intricately designed to get blood, oxygen, and nutrients to each and every cell through the human body. While bringing cells the necessities to replenish themselves and multiply, the circulatory system also aids in the removal of waste and the return of deoxygenated blood back to the heart and lungs. This is done through the heart, lungs, arteries, veins, and capillaries.
The heart is a muscular cone-shaped organ that keeps the blood moving within the circulatory system. Being about the size of a closed fist in a child, and two fists in an adult, it maintains a beat of anywhere from 60-80 beats per minute, but

The vessels main purpose is to transport blood from the heart too the various tissues throughout the body.
The blood is one of the most essential parts of a working circulatory system. The eight too ten pints of blood is the sticky, red liquid that is constantly flowing through our veins, carrying nutrients and oxygen to tissues found throughout the body. The hypothalamus part of the brain is known as the regulating system for the entire body. This is what keeps our blood at a normal temperature of 98.6 degrees Fahrenheit. Although blood is always red, it may appear to be different colors (blue, dark red, possibly even greenish). This is caused by the amount of oxygen found in the blood as it flows through our veins. Less oxygen leads to a darker cooler tone, and even the blue color. The blood is composed of red and white blood cells, platelets, plasma, and hemoglobin. Hemoglobin is a complex protein made of iron that attaches itself to the red blood cells, which are carrying oxygen to the body cells, and carbon dioxide back to the lungs. White blood cells destroy disease-causing toxins and bacteria from the blood. Plasma, is the the clear fluid where the red and white blood cells are found. Plasma carries food and other useful substances to the cells and removes carbon dioxide. Smaller than the blood cells, platelets contribute to the blood clotting process.
Not only does the circulatory system provide the blood throughout the
The cardiovascular system is the process of the heart pumping the blood around the body through blood vessels, arteries, veins and capillaries. The main functions of the system are to transport materials to and from the cells around the body, to assist in temperature, to keep the levels of fluid in the body at the correct level, to distribute heat around the body and to defend the body. This system is the heart, which is a muscle that pumps blood around the body through arteries, veins and capillaries. Blood transports oxygen to the body cells which helps them to metabolise energy in the body. During this process the blood is also getting rid of any waste products of respiration, carbon dioxide and water. Blood also helps to supply heat, hormones, nutrients, salts and urea around the body. The heart is placed in between the lungs which is protected by the rib cage and is the size of a fist.

Our cardiovascular system is composed of the heart and blood vessels. The main purpose of this system is to transport substances throughout the body. Even though transportation is the main function of the cardiovascular system, it is not the only function. Along with transportation we have protection and regulation.
The cardiovascular system, however, would not be able to effectively complete these functions without help from what is sometimes referred to as the body’s hardest-working organ- the heart. Approximately the size of a fist, the heart is contains four chambers (the uppermost are called the atria and the lowermost are called the ventricles) and four valves. Additionally, the heart is surrounded by the pericardium, a structure that serves to protect the heart, keep the heart stabilized in the chest, and
The Circulatory system is responsible for the transport of blood throughout the body. The Circulatory system has many organs. The main components are the heart, the blood, and the blood vessels. It also consists of arteries, arterioles,
Functioning as a rapid delivery system, bringing molecules of nutrients and oxygen to each cell, and enabling the diffusion process are the roles of the circulatory system. Through blood vessels, moved by the internal pump, the heart, blood carries molecules of nutrients and oxygen. In both systemic and pulmonary circuits, veins move blood towards the heart, while arteries transport blood away from the heart. Also entitled the blood circulatory system, the cardiovascular system
The cardiovascular system uses blood to transport oxygen, nutrients, and other materials throughout the body. The heart is made of cardiac muscle and is composed of 4 distinct chambers. The right side of your heart collects blood on its return from the rest of our body. The blood entering the right side of your heart is low in oxygen. Your heart pumps the blood from the right side of your heart to your lungs so it can receive more oxygen. Once it has received oxygen, the blood returns directly to the left side of your heart, which then pumps it out again to all parts of your body through arteries (the aorta).
Did you know the circulatory system comprises the heart, veins, capillaries and arteries? The system moves pure oxygenated blood in a continuous and controlled way from the lungs and heart so that blood can reaches every cell. Blood travels through a type of network of vessels that include capillaries that permeate every tissue of the body. Once it’s depleted of oxygen, the blood returns to the lungs and heart and the cycle continues.
The cardiovascular system is responsible for transporting blood carrying oxygen through the body. Homeostasis is especially important in this system because the blood cells maintain the human body functioning. The water and intracellular fluids are constantly performing osmosis as the cells travel through the body.
The cardiovascular systems function is to pass blood through ones body keeping their muscles oxygenated, to keep nutrients that are needed in the body and to help get rid of metabolic waste. The cardiovascular system is made up of three components, these are; the heart, the blood and the blood vessels.
The gross structure of the cardiovascular system is that it consists of the heart, which is a body pump with its complex tubes (arteries, veins and capillaries) that cross the whole of the human body carrying the blood. The blood contains oxygen, nutrients, wastes and immune and other useful cells that help to provide the homeostasis and basic function of the human cells and organs. The pumping action of the heart usually maintains a balance between cardiac output and venous return. The cardiac output is the amount of blood that is pumped out by each ventricle in one minute.
The cardiovascular system and the circulatory systems work hand in hand. The main functions of the cardiovascular system are to transport nutrients, oxygen, and hormones to cells throughout the body, protect the body by white blood cells against foreign microbes and toxins, and platelets for blood clotting and regulate body temperature, pH fluid, and water content of cells. It’s a closed system, and the main organs associated with the cardiovascular system is the heart and the blood vessels.
The hearts role is to pump oxygenated blood to every cell in the body by having a continuous beat. Throughout time the heart has created mystery, however current technology has solved most of the mystery, there still remains an enchantment and eagerness to learn more.
The function of the cardiovascular system is to circulate blood through a large network of vessels that run throughout the body. This provides each cell with nutrients and oxygen and also helps to dispose of waste products which is a main purpose of the cardiovascular system.
It consists of the heart, a system of arteries, veins, and capillaries (Anand, Mahindra). The heart is a muscular organ that consists of four chambers, 2 atria, and 2 ventricles; all of these used to pump blood into the body in a cycle (Anand, Mahindra). It transports and supplies us with many nutrients. The cardiovascular system is also responsible for the transport of oxygen, hormones, and cellular waste products throughout the whole body. It protects the body through its white blood cells (Anand, Mahindra). Anand Mahindra writes how the white blood cells clean up cellular debris and fight pathogens that have entered the body (Anand, Mahindra). In other words, the white blood cells are responsible for fighting any sort of infected bacteria entering the body. All of this is occurs due to the cycle provided by the cardiovascular system and the works of the heart. Overall, there are multiple risk factors that air pollution can cause to our body affecting the cycle mainly to the heart.
