Research & Methods Concerning Potassium Channels in the Cardiovascular System Response to Diabetes Mellitus and Hypertension ABSTRACT Research concerning the functional role of potassium ions in the cardiovascular system with respect to hypertension and diabetes mellitus has boomed in the past decade. Through a series of experiments‚ data has been gathered which shows the diverse response of K+ channels in the cardiovascular system when exposed to these diseases. In elevated glucose levels

the heart: • blood drains into the right atrium through the superior vena cava‚ inferior vena cava‚ and the coronary sinus (drains the heart muscle itself)→Right Ventricle→pulmonary semilunar valves→lungs→pulmonary veins→left atrium→bicuspid valve→left ventricle→aortic semilunar valve→systemic circuit. What the valves do: • Prevent backflow into the atria and ventricles‚ ensuring that blood only flows one way through the heart. what vessels bring blood to the heart and take blood away‚ etc...

heart’s blood vessels called the aorta‚ vena cava‚ pulmonary trunk‚ and pulmonary veins. There are two different types of circulatory loops in the human body the Pulmonary Circulation and the Systemic Circulation. The Pulmonary arteries brings blood from the right side of the heart to the lungs where then the blood picks up oxygen and returns to the left side of the heart. The pumping chambers that support the pulmonary circulation are the right atrium and left ventricle.

The Cardiovascular System: Intrinsic Conduction System 1. The intrinsic conduction system consists of __autorhythmic cardiac______ cells that initiate and distribute __impulses___ throughout the heart. 2. The intrinsic conduction system coordinates heart activity by determining the direction and speed of _heart depolarization___. This leads to a coordinated heart contraction. 3. List the functions for the following parts of the intrinsic conduction system: a. SA Node __initiates the depolarizing

keep them in physiological limits. To achieve this‚ every organ works together and thus the body works together as a whole. This requires body to communicate with the organs‚ this is established through two very highly specialized systems; nervous system and endocrine system‚ they use electrical impulses and hormones to communicate respectively1. It is vital for our body to maintain homeostasis for our survival‚ this ability of the body allows us to adapt to our environment which is why we can live

Describe the Structure and Function of the Cardiovascular System Changes in Stroke Volume Stroke volume is the amount of blood pumped out the left ventricle‚ every beat your heart makes. It can differ from your resting heart beat and your heart beat when exercising. Normally‚ when exercising‚ your heart rate increases meaning the stroke volume also increases. The blood pumped by the left ventricle is oxygenated‚ and will deliver oxygen to the muscle. The more blood injected in a heartbeat means the athlete
