Sinus Node Dysfunction

Sinus Node Dysfunction, Symptoms, Treatment

Sinus node dysfunction primarily affects older patients, especially those with another heart disorder or diabetes. Sinus pause is the temporary cessation of sinus node activity, seen on electrocardiography (ECG) as the disappearance of P waves for seconds to minutes.   The pause often triggers the escape recreation in lower pacemakers, preserving heart rate and function, but […]

Cardiac muscle tissue function

Cardiac Muscle tissue function and Intercalated Discs

Cardiac muscle tissues are one of the three types of muscle groups on your physique. The other two forms are skeletal muscle groups and easy muscle tissues.   Cardiac muscle mass just discovers for your coronary heart, where it performs coordinated contractions that enable your heart to pump blood via your circulatory system.   Cardiac […]

Target heart rate for weight loss

Target heart rate for weight loss during workout and how to measure

Your heart rate can help you measure the intensity of your exercise. For most people, the heartbeats between 60 and 100 times per minute while resting. Heart rate increases during exercise. The stronger the exercise, the more your heart rate will increase.   When you exercise in your heart rate zone to burn fat, your […]

circulatory system facts

Important facts of circulatory system

The circulatory system includes the heart, blood vessels, and blood, is vital to fight diseases and maintain homeostasis (adequate temperature and pH balance). The main function of the system is to transport blood, nutrients, gases, and hormones to and from the cells throughout the body.     Circulatory system facts The circulatory system is extremely […]

Types of capillaries

Types of capillaries and their functions

The walls of the capillaries are so thin that the molecules can diffuse through the walls of the capillaries to the membranes of the cells that surround the capillaries.   The pulmonary capillaries allow oxygen to diffuse into the blood, while carbon dioxide is able to diffuse outward into the lungs. The arteries and veins […]

Capillaries function

Functions of Capillaries and their Structure

Capillary is a blood vessel. It has no muscular/elastic tissue of other blood vessels. It has a single cell wall to help the materials be transported through organisms. Small capillaries are smaller than any other blood vessel.   They are about 5-10 μm large, which connect arterial and vascular and allow the transfer of water, […]

superior vena cava functions

Superior vena cava functions

The better main vein (SVC) is the better of the two cava veins, the great venous trunks that return oxygen-free blood from the systemic circulation to the right atrium of the heart. It is a large diameter (24 mm) vein, but short, which receives a venous return from the upper half of the body, above the […]

SA node function

SA node function & their phase & understanding sinus node

The SA node, also known as the sinus node. It is a group of cells located in the wall of the right atrium of the heart. These cells have the ability to spontaneously produce an electrical impulse (action potential, see below for more details) that travels through the heart via the electrical conduction system, causing […]

Coronary sinus function

Coronary sinus function & structure of coronary sinus

The coronary sinus is a collection of veins, which connect to a large vessel that collects blood from the myocardium. It provides less oxygenated blood to the right atrium, as well as better and weaker veins. It occurs in all mammals, including humans.   The name comes from the Latin crown, which means the crown […]

Aorta function

Aorta function & aorta descending, Aortic arch treatment

The aortic arch is part of the main artery that bends between the ascending and descending aorta. He leaves the heart and rises, then goes down to create a bow. The aorta distributes the blood from the left ventricle to the rest of the body.   Certain aortic complications may ultimately lead to blockage of […]
