"Heart and Circulatory System ." KidsHealth - the Web's most visited site about children's health. N.p., n.d. Web. 3 Dec. 2012. <http://kidshealth.org/parent/general/body_ The Circulatory System Heart - a muscular organ that pumps the blood through the circulatory system. Level of Organization The circulatory system in the levels of organization is the organ system level which is made up of organs, tissues and cells. Blood vessels -A tubular structure carrying blood through tissues and organs; a vein, artery, or capillary. FUN FACTS - Definition Circulatory System Helps Homeostasis The circulatory system is an organ system also known as the cardiovascular system that circulates blood, supplies cells, and removes waste. It sends oxygen and nutrients to cells so the other organ systems will work properly. The organs in the circulatory system consist the following: the heart, arteries, veins, capillaries, blood vessels. Fun Facts - 2 circulatory systems: pulmonary circulation & systemic circulation -The heart beats around 3 billion times in the averages person's life. -About 8 million blood cells die in the human body every second, and the same number are born each second. - Thin a tiny droplet of blood, there are some 5 million red blood cells. Takes about 20 seconds for a red blood cell to circle the whole body. -Red blood cells make approximately 250,000 round trips of the body before returning to the bone marrow, where they were born, to die. -Blood cells may live for about 4 months circulating throughout the body, feeding the 60 trillion other body cells. - -Blood circulates the entire body in 20 seconds. -The heartbeats about 30 million times in 365 days. - -One drop of blood has about 5 million red blood cells and 12 thousand white blood cells Fun Facts Some Diseases In The Circulatory System cardiovascular disease,arteriosclerosis,high blood pressure,Aortic Aneurysm, Coronary artery,Deep vein thrombosis. Arteries- muscular-walled tubes forming part of the circulation system Veins -tubes forming part of the blood circulation system of the body, carrying mainly oxygen-depleted blood toward the heart. Capillaries- Capillaries have very thin walls, allowing oxygen and nutrients to pass from the blood into the tissues. Main Organs The main organs in the circulatory system is the heart, arteries, veins, capillaries and blood vessels. The circulatory systems transports nutrients, minerals and vitamins and oxygen to the body's cells which maintains homeostasis or internal stability. Muscular system- it provides the muscles with oxygen and nutrients by transporting these materials to it so they can function properly.

Skeletal- the bones produce blood cells.

Lymphatic- Lymph nodes secrete into the circulatory system.

Respiratory- provides the circulatory system with oxygen and in turn takes out waste (CO2)

Endocrine- secretes hormones into the circulatory system.

Digestive- breaks down nutrients and then is absorbed into blood and transported to all the parts of the body. Systems That Work With Circulatory System Bibliography http://www.biologyjunction.com/heart_cross_section.gif Bibliography Circulatory System with Stimulus When our bodies are using a lot of energy, our heart pumps blood faster to get the needed nutrients to the other organ so they can do there job. When we are at rest, the heart pumps just enough for the rest of the body to function properly while we rest. "Heart and Circulatory System ."
