Brachiocephalic artery

Hypovolemic shock is the result of severe blood/fluid loss causing the heart to inadequately circulate oxygen to the rest of the body (Workman, 2013, pp. 812). In this condition, there is sudden decrease in blood volume within the vascular space causing a drop in mean arterial pressure. This decrease in mean arterial pressure causes a sudden loss in the oxygen carrying capacity of the blood related to the sudden decline in available red blood cells. As the heart is unable to properly pump oxygen…

arteriosclerosis or simply from his hypertension. The percentage rate is low when linking epistaxis with hypertension, but in the doctors case he stopped taking his medication. Arteriosclerosis is caused by HBP which can also lead to CAD (Coronary Artery Disease). The blurred vision and dizziness go hand in hand and are also signs of a cardiovascular disease. The auscultation observed rales and crackles. Crackles are caused when small air passages open during inspiration increase during…

Chest pain? Lightheadedness? Heart palpitations? Can’t catch your breath? You may be experiencing paroxysmal atrial fibrillation. Atrial fibrillation (AF or AFib) occurs when the atria (upper chambers of the heart) lose their normal rhythm and beat chaotically. When this happens, blood isn’t flowing through the heart and body efficiently. This inefficient flow can cause blood to pool inside the atria, increasing the risk of blood clots. Atrial fibrillation can be associated with stroke,…

Deca 250 or Deca Durabolin has long been used in the world of athletics and until today, has been the most popular steroids in sports. Its fame is due to its overly high deca-durabolin- webanabolic activity. As a result, as it mass increase, so as its side effects. Also, it yields a lesser water retention, doesn’t have any effect on a person’s blood pressure and most important of all, it isn’t toxic to the liver and kidneys as most body building substances. One more notable thing about Deca…

The respiratory system is responsible for taking in oxygen and releasing carbon dioxide. The lungs are the main organs in the respiratory system. According to the American Lung Association, red blood cells collect the oxygen from the lungs and carry it throughout the body where it is needed. As the red blood cells travel through the body, they collect the carbon dioxide, taking it back to the lungs where it is then exhaled. The human body needs oxygen in order to sustain itself. The average…

They function is to circulate the blood around the body to all the muscles. The red blood cells carry oxygen to all the muscles through the vein (carries blood to the heart). The veins have thin walls and contain blood under the low pressure. The arteries (carries blood away from the heart) have thick muscular walls and small passage ways. They contain blood under high pressure. The last blood vessels is the capillaries (found in the muscles and the lungs). They are one cell thick, and have low…

- Inner Layer; An inner endothelial cell layer called tunica intima lines the arteries and veins. The tunica intima, is a single layer of squamous epithelial cells that lines the inner surface of the entire cardiovascular system. In many veins, the tunica intima is equipped with pockets that act as one-way valves. These valves prevent the back flow of blood and allow the veins to act as supplemental pumps that help to keep the blood following in one direction, back toward the heart. The activity…

My group did our dissections on the Frog, they belong to the Chordate phylum because of its endoskeleton, and their nerve cord that runs along the spinal cord and connects to their brains. This means that they have a central and peripheral nervous system. Back to their brains, they’re divided into three parts, the fore-brain, mid-brain and hind-brain. The fore-brain controls the frogs sense of smell (the Olfactory lobe), along with the cerebral hemispheres, and diencephalon. The mid-brain…

diseases can be obtained from sodium. High Blood Pressure is the first objective we will discuss. High Blood Pressure is an indicator to how much pressure the blood puts on the walls of the arteries. Blood Pressure is determined by blood volume and this tells how much blood is being circulated in the arteries. Anyone who has high blood pressure must watch how much sodium intake they consume. Also, high blood pressure can cause serious health problems. I am also going to talk about the heart…

Cerebrovascular accident (CVA) is also known as stroke for short. A stroke is a disease that does not allow the arteries to carry oxygen to the brain. They are the fifth top causes of casualty in America. Knowing the signs and symptoms of a stroke and seeking medical attention may decrease the risk of death. There are a few diverse types of strokes, Transient ischemic attack, hemorrhagic stroke, and ischemic strokes. The first one is transient ischemic attack also known as TIA; it is a clot…
