Cardiovascular Continuum


Array

The cardiovascular continuum links various risk factors, like hypertension and high cholesterol levels, with different types of heart disease that become progressively more severe throughout a person's life. By treating risk factors that occur early on in the cardiovascular continuum, like hypertension, it may be possible to prevent or slow the development of heart disease and to prolong life. Read more

Developing Heart

Developing rapidly and early, the heart is the first organ to function in the embryo, and it takes up most of the room in the fetus's midsection in the first few weeks of its life. During its initial stages of development, the fetal heart actually resembles those of other animals. In its tubelike, two-chambered phase, the fetal heart resembles that of a fish. In its three-chambered phase, the heart looks like that of a frog. As the atria and then the ventricles start to separate, the human heart resembles that of a turtle, which has a partial septum in its ventricle. The final, four-chambered design is common to mammals and birds. The four chambers allow low-pressure circulation to the lungs and high pressure circulation to the rest of the body. Read more

Marvel of the Cardiovascular System

The cardiovascular system, which consists primarily of the heart and the blood vessels, is the first organ system to develop in humans. It provides oxygen and nutrients to all the organs and tissues of your body.
Lungs The lungs have a double blood supply: the pulmonary circulation allows for gas exchange with the alveoli (air sacs), and the bronchial circulation supplies blood to the lung tissue. Blood from the bronchial circulation drains into the left side of your heart through the pulmonary arteries. The pulmonary circulation is a low-pressure, low-resistance system, made possible by the four-chambered heart. Read more
