What is the name of the artery in the neck and wrist? Several arteries in the human body are important for Emergency Responders to know about. The carotid artery on each side of the neck is very close to the skin and typically easy to locate; it is a powerful artery since it is close to the heart, taking oxygen-rich blood to the brain. The radial artery near the wrist may be used to feel for a pulse. However, as you’ll learn, a casualty may not have a detectable carotid or radial artery pulse, but may still have a heartbeat. Feeling for a pulse may not be the best way to determine if a casualty has a heartbeat. During Skills Development you’ll learn the technique of quickly scanning the patient for responsiveness and normal breathing. Where are the artery pressure points on the leg and arm used to control severe bleeding? The two main pressure points can be found in the arms (this is the brachial artery that can be found by placing several fingers under the upper arm, several inches down from the armpit, then pressing inward until you feel a pulse) and the legs (this is the femoral artery that can be found on the inside of the thigh near the area of the groin). What arteries supply blood to the heart muscle? Coronary arteries supply blood directly to the heart. Heart attacks and cardiac arrest are two major problems. The lymphatic system

What are the two primary purposes of the lymphatic system? Like the cardiovascular system, the lymphatic system forms a vast network of vessels and is part of the body’s circulatory system. The two primary purposes of the lymphatic system are to transport returning fluids that have collected in tissues to the bloodstream and to filter out foreign particles, microorganisms and other tissue debris from the body. What are problems related to the lymphatic system? An injury to the abdomen may cause life- threatening internal bleeding from the spleen. Since a person with an infection may have inflamed, swollen and tender lymph nodes, you should be on the lookout for these indications during injury or illness assessment. The lymphatic system also removes injected venoms following a bite or sting from poisonous animals. Slowing the movement of lymph may reduce the spreading of venom from a poisonous bite or sting. As with any serious injury or illness, you provide initial care for the patient by alerting Emergency Medical Services.
