Background —whether diabetes mellitus (dm) adversely affects left ventricular (lv) structure and function independently of increases in body mass index (bmi) and blood pressure is controversial methods and results —echocardiography was used in the strong heart study, a study of cardiovascular disease in american indians, to compare lv measurements between 1810 participants with dm and 944.
The major blood vessels connected to your heart are the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart), and the coronary arteries (which supply blood to the heart muscle.

As we previously learned, the heart is the ultimate workaholic, and it pushes your body's complete supply of blood through your blood vessels over 1,000 times a day in this lesson, we will take a look inside the heart and identify the structures that make up this vital organ.
Structure of heart it is hollow, muscular organ that contracts at regular intervals, forcing blood through the circulatory system it is cone-shaped, about the size of a fist, and is located in the centre of the thorax, between the lungs, directly behind the sternum (breastbone. These are the heart chambers that receive blood returning to the heart because they are primarily receiving chambers, we do not think of the atria as the true pumps of the heart instead, blood flows into the atria under low pressure from the blood vessels and then passively drains through on its way to the lower two chambers, which are called the ventricles. The structure of the heart (together with the functions of the heart) are essential learning for students of courses in human biology, anatomy and physiology, and many holistic therapies this page is part of a series about the vascular system.

Blood from the body returns to the heart via vena cavas r atrium fills with blood and contracts, pushing open the tricuspid valve (this allows blood to flow into the r ventricle) at the same time, blood returns from the lungs via the pulmonary veins into the l atrium.
