Internal carotid artery

blockage in the arteries of the heart. The common signs and symptoms include- Pain and discomfort in the heart and it may radiate to arm, shoulder, neck or throat. Nausea Fatigue or tiredness Shortness of…

Sarah Hill 0583028 BIOL 3830H F03 Simon Tapper Wednesday, October 11th, 2017 The relationship between blood physiology and cardiac ability in Equus caballus compared to Bos taurus and Capra aegagrus hircus compared to Canis lupus familiaris Abstract The purpose of this experiment was to study the relationship between blood physiology and the ability to transport oxygen. The red blood cell content, hematocrit percent, and hemoglobin concentrations of Equus caballus (horse) and Bos taurus…

The purpose of this study was to further understand the cardiovascular system under normal conditions, stress and postural changes. To help illustrate the effects of the cardiovascular systems components the dive reflex and venous system were also tested. In the tilt table test, the response of effect of gravity and sympathetic activation of the heart were being examined to determine the response of BP, MAP, PP, HR, SV, CO and TPR during Effects of Posture on Blood Pressure (BP). It was…

Marilyn Monroe once sang, “Diamonds are a girl’s best friend.” This lyric about girls and their diamonds makes sense for obvious reasons. Diamonds are shiny, make women feel like princesses, and are a symbol of “love”. However, diamonds have an intimidating competitor, chocolate. No matter how big the “rock” is, some women would prefer delicious, melt in your mouth, chocolate. Their wise decision could potentially have some great upsides to it. For instance, dark chocolate has numerous health…

The narrowing of the artery walls is going to make moving oxygen through them much harder than it would be in healthy arteries. So if a patient with atherosclerotic arteries performed the same test, they would show a higher double product. The patient 's resting double product is going to start higher and, with exercise, the patient will most likely…

Diagnosis History and clinical examination in NTG is similar to PAOG with special attention to some differences. 1) History Special attention should be made to systemic associations and predisposing factors, including migraine, Raynaud’s phenomenon, episodes of shock, systemic hypotension and obstructive sleep apnea. All these factors may contribute to compromised ocular blood flow. (Kanski & Bowling, 2011). 2) Clinical examination There is evidence that the left eye is 2.5 times more likely…

elevated troponins and elevated ST segments on EKG. A 2D echocardiogram showed left ventricular apical akinesis with basal hyperkinesia. He had a coronary angiogram completed, and it showed no stenotic arteries, however they also injected ergonovine which appeared to cause a right coronary artery spasm. The patient was treated with calcium channel blockers and nitrates. A follow up two weeks later showed normal wall motion as well as a sigmoid septum, and normal systolic function. He was…

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…

Goy, David The Functions of Blood Blood plays a very important role in maintaining the normal functions of the different, tissues, organs and organ systems in the body. It serves as the primary medium for carrying and transporting important gases, minerals and nutrients needed to maintain homeostasis. Blood is composed of several components: plasma, red blood cells, white blood cells and platelets. Plasma is the fluid compartment of the blood; it carries ions, minerals, nutrients, gases,…

Drowning is known dying due to submersion and inhaling water. Most drownings occur within males and children. Most people drown due to not knowing how to swim, Alcohol use while swimming , and/or no supervision while swimming. One thing most people do not pay attention to is how drowning in fresh water can be different from drowning in salt water. More drownings occur in fresh water then they do in salt water and in some case the victims can die hours after the incident. Water goes into the…
