Cardiovascular The cardiovascular system is consists of the heart and network of arteries‚ veins‚ and capillaries that transport blood throughout the body. There are two primary circulatory loops in the human body: the pulmonary circulation loop and the systemic circulation loop.

section of the stomach. The stomach is divided into several regions: the cardiac region‚ body region‚ fundic region‚ and pyloric region. The stomach works to mix and churn the food‚ which aids in further digestion of carbohydrates. At this point‚ the bolus is converted into a semifluid paste of bolus and gastric juices called chyme.

CAD is thought to begin with damage or injury to the intimal layer of coronary artery‚ sometimes as early as childhood. The damage may be caused by various factors‚ including: smoking‚ hypertension‚ hypercholestromia‚ diabetes or insulin resistance‚ radiation therapy to the chest‚ as used for certain types of cancer‚ and sedentary lifestyle.
