External carotid artery

Contrary to systolic dysfunction, diastolic malfunction is characterized by normal contractility and a typical ejection fraction. The relaxation of ventricles in this disorder is impaired, resulting in an increase in ventricular pressure into the left atrium and pulmonary venous system leading to signs of pulmonary and systemic venous congestion. This decrease in preload results in a decrease in blood volume, especially during periods of increased activity or exercise, when blood is unable to…

sends a message to the respiratory control center in order for it to adjust the concentrations. At rest, the receptors that maintain ventilation are the central and peripheral chemoreceptors. The peripheral chemoreceptors are located in the brain, carotid bodies, lungs, and muscles. They can…

There are a 11 body systems there is the INTEGUMENTARY SYSTEM which The integumentary system is the organ system that protects the body from various kinds of damage There is also the MUSCULAR SYSTEM The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body. There is also the SKELETAL SYSTEM The skeletal system includes all of the bones and joints in the body. Each bone is…

The three basic types of blood vessels, including capillaries, arteries and veins. • Arteries take oxygen-rich blood away from heart. • Veins take blood back toward heart. • Capillaries are very tiny blood vessels that form a connection between arteries and veins. Transfer of nutrients, oxygen and wastes in and out of body facilitated by the capillary. 3. The Blood The heart pumps blood throughout body. The…

happens when a part of the brain dies because of either clotting or rupture of blood vessels. Stroke is one of the leading causes of death and disability in the world. Strokes can happen when: An artery is blocked due to blood clotting where a part of brain goes without blood for few minutes. An artery ruptures and starts bleeding into the brain How do strokes affect people? — The effects of a stroke depend on ●Which part and how much of the brain is affected ●How quickly the stroke is…

On this day I saw my life flash before me because as I was driving to class my car brakes locked up and then I hit a patch of black ice right before turning next to the St. Cloud Prison on highway 10. My car slid about 50 feet and all I could do was just hold my steering wheel and pray for the car to stop. During this moment my sympathetic nervous system (SNS) was reacting to this tragic…

Venous Disorders Definition Venous disorders are the group of pathologies that refers to abnormal functioning of the venous system. Venous disorders fall into two general classifications: 1. Blockage as a result of a blood clot called thrombosis 2. Insufficient venous drainage known as insufficiency Thrombosis includes:  Superficial Thrombophlebitis  Deep Vein Thrombosis (DVT) Insufficiency comprises of:  Varicose Veins  Spider veins  Chronic Venous Insufficiency Pathophysiology…
