Aorta

Superior Mesenteric Artery Syndrome is a rare gastrointestinal disorder. This syndrome can also be known as SMA Syndrome. It is a very rare acquired vascular compression disorder. IN this disorder the Aorta and Superior Mesenteric Artery compress on the intestine causing many digestive issues. The compression is caused when the angle between the two arteries is very low usually 6° to 15° or 2 to 8 mm. The normal angle between these two arteries is between 25° to 60° or 10 to 28 mm. The arteries…

wall that bulges from the normal force of blood pumping through the body. An abdominal aortic aneurysm is an aneurysm that occurs in the lower part of the aorta, the main artery of the body. The major concern with an abdominal aortic aneurysm is that it can enlarge and burst (rupture) or blood can flow between the layers of the wall of the aorta through a tear (aortic dissection). Both of these conditions can cause bleeding inside the body and can be life threatening unless diagnosed and…

valve which is made up of two triangular flaps, prevents blood from flowing back into the atrium once it enters the left ventricle atrium and instead continuing its journey through to the aorta. http://www.healthline.com/human-body-maps/mitral-valve The aortic valve: The aortic valve is located between the aorta and the left ventricle. The aortic valve is made up of three flaps. The aortic valve functions to prevent regurgitation of oxygenated blood as it leaves the heart and reenters the…

normal. Diagnosis involves the use of chest cardiograph, which shows a boot-shaped heart due to the enlarged right ventricle, decreased pulmonary markings, and a prominent aorta (Ball & Bindler, 2008). ECG reveals a right ventricular hypertrophy and an echocardiogram shows VSD, obstruction of pulmonary outflow, an overriding aorta, and the size of the pulmonary arteries. Anatomic defects are made visible be cardiac catheterization and blood tests will show high levels of hematocrit and…

1 Hypothalamus – a small region of the brain that is a major link between the nervous and endocrine system. The hypothalamus controls the autonomic nervous system and regulates body temperature, hunger, thirst, fear, rage, and sexual behavior. The hypothalamus control feeling such as pain, stress, and emotional experiences. (1) 2 Pituitary gland – the “master endocrine gland” because it secretes many hormones that control other endocrine glands. It is a “pea-shaped structure that attaches to…

connected to the right atrium – the superior vena cava, the inferior vena cava, and the coronary sinus; the pulmonary trunk stems from the right ventricle; the left atrium has four pulmonary veins the join it; and connected to the left ventricle is the aorta. (Farley, McLafferty, & Hendry,…

Methods of analysis: Andrea is a 35 year old female who regularly takes part in cardiovascular exercise. She has recorded her beats per minute (BPM) and blood pressure before, during and after performing exercise with a heart rate monitor and a sphygmomanometer. She completed this experiment during a spin class within a controlled environment and on a fixed spin bike. Findings: BPM Before exercise 96 Average heart rate during exercise 142 Maximum heart rate during exercise 174 1 minute after…

1.6.3 Hematopoisesis in zebrafish Within the past two decades, the zebrafish (Danio rerio) has become an excellent model to study the development of hematopoietic stem cells (HSCs). The genes and molecular signaling pathways controlling hematopoiesis are highly conserved between fish and mammals. Both share all major blood cell types that are generated from common lineages of hematopoietic stem cells [13]. This is an important advantage over invertebrate models that lack the complex…

be noted when using a stethoscope. Typically, these sounds come from the abnormal motion of blood amid cardiac chambers and across valves. As a result, turbulence occurs, bringing about “vibrations in the chambers of the heart or outflow vessels (aorta or pulmonary artery) that are detected as audible, low-frequency sounds,” (Klabunde, 2016). These sounds are different from the regular heart sounds that symbolize the closing of the atrioventricular and semilunar valves amid the cardiac cycle.…

Coronary CT angiography is also non-invasive. A major advantage of CT is that it is able to view bone, soft tissue and blood vessels all at the same time.4 It is therefore suited to identify other reasons for your discomfort such as an injury to the aorta or a blood clot in the lungs.4 A potential added benefit of CTA in these patients is the detection of non-cardiac findings, which may provide an alternate explanation for their…
