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. Within a tiny droplet of blood, there are some 5 million red blood cells. It 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. Red blood cells may live for about 4 months circulating throughout the body, feeding the 60 trillion other body cells.
The circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, hormones, oxygen and other gases 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.
Cardiac catheterization is a common medical procedure used today and involves inserting a catheter (a long, thin tube) into a patient's blood vessel and threading it to the heart. Doctors can use the technique to perform a number of diagnostic tests on the heart, including measuring oxygen levels in different parts of the organ and checking the blood flow in the coronary arteries.
Unlike most other cells in the body, red blood cells have no nuclei. Lacking this large internal structure, each red blood cell has more room to carry the oxygen the body needs. But without a nucleus, the cells cannot divide or synthesize new cellular components.
The circulatory system includes the heart, blood vessels and blood, and is vital for fighting diseases and maintaining homeostasis (proper temperature and pH balance).

The pulmonary circulatory system sends oxygen-depleted blood away from the heart through the pulmonary artery to the lungs and returns oxygenated blood to the heart through the pulmonary veins, according to the Mayo Clinic.
The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients
If you were to lay out all of the arteries, capillaries and veins in one adult, end-to-end, they would stretch about 60,000 miles (100,000 kilometers). What's more, the capillaries, which are the smallest of the blood vessels, would make up about 80 percent of this length.
A condition called stress cardiomyopathy entails a sudden, temporary weakening of the muscle of the heart (the myocardium). This results in symptoms akin to those of a heart attack, including chest pain, shortness of breath and arm aches.

Across the animal kingdom, heart rate is inversely related to body size: In general, the bigger the animal, the slower its resting heart rate. An adult human has an average resting heart rate of about 75 beats per minute, the same rate as an adult sheep. But a blue whale's heart is about the size of a compact car, and only beats five times per minute. A shrew, on the other hand, has a heart rate of about 1,000 beats per minute. http://www.livescience.com/39925-circulatory-system-facts-surprising.html
