Artery

cardiovascular diseases is coronary heart disease. In which, the arteries harden and narrow due to plaque buildup that is known as atherosclerosis. Coronary heart disease usually leads to heart attacks because of high blood pressure, smoking, diabetes, and abnormal cholesterol levels. Furthermore, a study conducted by Hambrecht et al. (2000) was to determine if aerobic exercise training can improve coronary reserve in patients with coronary artery disease and endothelial disfunction. Vascular…

abdomen, or around the brain.A blood clot that forms in the arteries is differed from the blood clots that form in the vein. The reason is that the blood clot in the arteries leads to strokes, transient ischemic attack (TIA or mini-stroke), heart attack, or peripheral arterial clot and gangrene which is the death of body…

heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.” Web. . January 12, 2016 There are contributing factors that can lead to heart failure such as coronary artery disease, diabetes, obesity, and high blood pressure. Management of these diseases such as daily exercise, weight…

3. Explain the heart generates and conducts an electrical current. Page 388 The heart has its own built-in conduction system for generating action potentials spontaneously and coordinating contractions during the cardiac cycle. All the cardiac muscle fibers in each region of the heart are electrically linked together. The intercalated disks are connections that electrically join the muscle fibers of the heart into a single unit that can conduct electrical impulses through the entire wall of…

“long-term force of the blood against your artery walls is high enough that it may eventually cause health problems”, (Mayo clinic, 2015). This disease is found by the amount of blood that the heart is pumping and the flow that the blood has to the arteries. When the heart has to pump more blood to the heart, then the arteries narrow and this can cause…

creates an imbalance of acid. To compensate with this imbalance the body speeds up its breathing taking in more oxygen and it also speed up the heart allowing the oxygen to be transported to the muscle faster. The human body cannot keep up with this for long. Eventually the heart and lungs reach their maximum work efforts and it can only neutralize the lactic acid for a short period of time. This buildup of lactic acid is what causes the muscles to feel fatigued and soar the next day. Once the…

Moyamoya disease is a progressive, occlusive disease affecting the cerebral vasculature and the arteries that feed it. Moyamoya is a Japanese term meaning “puff of smoke.” When you view the appearance of the disease on an angiogram the abnormal vascular collateral networks developing adjacent to the stenotic vessels. This disease causes the carotid artery in the skull becomes blocked or narrowed. This will cause the blood flow to your brain to become greatly reduced. Tiny blood vessels…

temporal lobes are the most prone to suffer from an ischemic stroke due to their shared blood supply. The frontal lobe is located within the anterior cranial fossa, whereas the temporal lobe is situated in the middle cranial fossa. The middle cerebral artery (MCA) is the region of interest as this is the most common site for ischemic strokes. The MCA consists of four sections. The M1 segment consists of lenticulostriate vessels which irrigate the basal ganglia. The M2 segment extends anteriorly…

Arterial system of frog Blood vessels, which carry oxygenated blood away from heart to different part of the body, are called arteries. They constitute a system called arterial system. Truncus arterious gives two branches right aortic trunk and left aortic trunk. Each aortic trunk again divides into three branches- a) Carotid arch: it divides into – Lingual artery – it supplies blood to tongue and hyoid. Common carotid – it supplies blood to buccal cavity and brain. it consists swelling at the…

1. Which do you think are the two, most common places to detect pulse and count the heart rate? The carotid pulse and the brachial pulse because the arteries are the larger ones that are near the surface of our skin so we can feel the pulse more. 2. What are some factors that can increase or decrease the heart rate and the beat you feel at each pulse point? Doing certain exercises can help increase the heart rate and to decrease the heart rate your can do something more relaxing. 3. Athletes…
