Circulatory System

Introduction to Circulatory System

The circulatory system is a network that carries blood throughout the body. All animals except the simplest kinds have some type of circulatory system. The human circulatory system supplies the cells of the body with the food and oxygen need

to survive. At the same time, it carriescarbon dioxide and other wastes away from the cells. The circulatory system also helps regulatebody temperature and carries substances that protect the body from disease. In addition, the system transports chemical substances called hormones, which help regulate the activities of various parts of the body.

Function of the body system, or what circulatory does and is responsible for doing?

The circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, oxygen and other gases, and hormones to and from cells. Without the circulatory system, the body would not be able to fight disease or maintain a stable internal environment — such as proper temperature and pH — known as homeostasis. While many view the circulatory system as simply a highway for blood — it is also known as the cardiovascular system — it is made up of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary) and arteries, veins, coronary and portal vessels (systemic). In the average human, about 2,000 gallons (7,572 liters) of blood travel daily through about 60,000 miles (96,560 kilometers) of blood vessels. An average adult has 5 to 6 quarts (4.7 to 5.6 liters) of blood, which is made up of plasma, red blood cells, white blood cells and platelets. In addition to blood, the circulatory system moves lymph, which is a clear fluid that helps rid the body of unwanted material.

Major organs

The heart is the most essential part of the circulatory system, but other organs take an
important role as well.The lungs, for example, are responsible for moving oxygen and other gases to and from the blood. The liver filters and detoxifies the bloodand other gases to and from the blood.The liver filters and detoxifies the blood sites for the production of red blood cells.The spleen stores red blood cells and white blood cells.The kidneys filter out cellular wastes from the blood and helps regulate the pH int he bloodstream.

Interactions with other systems

The circulatory system touches every organ and system in your body. The system is connected to all of your body's cells so that it can transport oxygen efficiently. When you breathe, the circulatory system carries oxygen to your cells and carries dissolved carbon dioxide back to the lungs. Every cell that needs oxygen needs access to the fluids in your circulatory system. The circulatory system and its fluids are super important to your digestive system that has absorbed nutrients from your food. Guess what? Hormones created by your endocrine system are sent through the body by the circulatory system.

Diseases/Disorders

Incomplete development of the heart or blood vessels before birth may result in defects known as congenital heart disorders. The causes are too much fat, cholesterol and calcium. This can restrict blood flow or in severe cases stop it all together, resulting in a heart attack or stroke. Another circulatory is disease, hypertension commonly called high blood pressure causes the heart to work harder and can lead to such complications as a heart attack, a stroke, or kidney failure. This weakness can be present at birth or the result of atherosclerosis, obesity, high blood pressure or a combination of these conditions. The circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, oxygen and other gases, and hormones to and from cells. In addition to blood, the circulatory system moves lymph, which is a clear fluid that helps rid the body of unwanted material. The heart, blood, and blood vessels make up the cardiovascular component of the circulatory system. The pulmonary vein sends the oxygen-rich blood back to the heart. An aortic aneurysm occurs when the aorta is damaged and starts to bulge or eventually tear, which can cause severe internal bleeding. Other disorders of the circulatory system result from damage or birth defects. Rheumatic fever can attack the valves that control the flow of blood through the heart.
