Potassium is very important in maintain cardiac function. At low potassium levels‚ heart cells become more excitable and result in premature contraction and result in atrial fibrillation. In AF‚ the atrial contractions are impaired which lead to the blood pooling in the atria and increase the risk

Chapter 16 Notes The heart lies in the mediastinum and is surrounded by a doubled layered membrane called the pericardium. The outer most layer of the pericardium is called the fibrous pericardium‚ which anchors the heart to surrounding structures. The inner layer is called the serous pericardium and is composed of two layers. The outer portion is called the parietal pericardium‚ the inner portion is called the visceral pericardium (epicardium). Epicardium- outer most layer of the heart wall

Without the cardiovascular system‚ we would not be alive. The cardiovascular system is essentially a synonym for the circulatory system which is "the system that circulates blood and lymph through the body‚ consisting of the heart‚ blood vessels‚ blood‚ lymph‚ and lymphatic vessels and glands" (Circulatory…). The cardiovascular system is crucial to have‚ as it supplies oxygen and gives nutrients to every part of our body. The cardiovascular system‚ in fact‚ is one of the most important systems consisting

Aquatic Adaptation Aquatic plants - also called hydrophytic plants orhydrophytes - are plants that have adapted to living in aquatic environments. -One of the main problems facing submerged aquatic plants is their inability to obtain oxygen. Unlike terrestrial plants‚ these plants cannot obtain the vital gas through their stomata because they are submerged in water. -Therefore‚ the stems‚ roots‚ and leaves of submerged aquatic plants posses aerenchyma cells‚ which supply oxygen to the rest of

heart rate of the consumer. The heart depends on an internal pacemaker system to keep it pumping consistently and at the right speed. Alcohol disturbs this pacemaker system and causes the heart to beat irregularly. Studies show that caffeine consumption raises blood pressure‚ or stroke volume of the heart by 4 points per minute‚ and heart rate goes up by about 3 beats per minute. Caffeine consumption raises pulse rates by stimulating cardiac
