Internal jugular vein

Superior Vena Cava Syndrome The Superior Vena Cava (SVC) is the main blood vessel that transports de-oxygenated blood from the upper body to the heart. The SVC is a short vein located in the anterior right Superior Mediastinum, which is the area found in the mid-line of the Thorax (Drake et al. 2010). The vein is surrounded by many structures involved in the respiratory and circulatory system including the right Bronchus and the Mediastinal lymph nodes (Martini & Ivonne 2004). Figure 1 is a…

Introduction Mitral valve regurgitation, also called mitral regurgitation, is a condition in which blood leaks from the mitral valve in the heart. The mitral valve is located between the upper left chamber of the heart (left atrium) and the lower left chamber of the heart (left ventricle). Normally, this valve opens when the atrium pumps blood into the ventricle, and it closes when the ventricle pumps blood out to the body. Mitral valve regurgitation happens when the mitral valve does not close…

The force in the arteries when blood pumped by the heart hits the walls of arteries is known as blood pressure . When the heart contracts,the highest pressure in the arteries is known as the systolic pressure . Whereas , the lowest pressure in the arteries in between two heart beats is referred to as diastolic pressure . A normal individual would have a blood pressure of below 120/80 mmHg. High blood pressure or otherwise known as hypertension is a condition when the force in the arteries are…

4. Notice how it feels to fully focus on your inhale. As you inhale, notice any particular feelings of tension or strain, and notice the sensation of your lungs and abdomen filling up as you inhale. 5. Now gently shift your awareness to focus more on your exhale. With each exhale, notice what it’s like to feel your breath passing out through your nostrils. And observe, without judgment, anything that you feel in your body. 6. For the next few minutes, continue to breathe gently and evenly.…

Congenital heart disease (CHD) is a defect related to the cardiovascular system. CHD alters the way blood flows into the heart. The irregularity of the heart in people with CHD is developed from birth though symptoms of the condition may not be present until adulthood. During the time of birth the closure of the ductus arteriosus (DA) should occur about 15 hours after birth though functional closure may be delayed for up to 3 months of life. Thus, an open DA is the functional indicator of…

Emily Howard (Laboratory Section 4019) Jennifer Dierkes (Laboratory Section 4019) Nicole Danh (Laboratory Section 4020) Wesley Ng (Laboratory Section 4020) Kayoti Farinholt (Laboratory Section 4020) Cardiovascular Assignment Work in groups (3-5) on this assignment and hand in one page of answers. I prefer you turn it in using the Canvas groups you have established and using the TurnItIn feature on Canvas. According to the ‘Frank – Starling Law” increasing preload will do what to stroke volume?…

The mitral valve (MV) plays a crucial role in cardiac function, controlling blood flow between the left atrium and left ventricle. The components of the valve include an anterior leaflet, a posterior leaflet, tendinous chords, papillary muscles, and a saddle shaped annulus at the atrioventricular junction.[1] Deviation in the morphology of any of these components of the valve may result in comprised mechanical integrity of the valve and abnormal leaflet closure.[1] With studies suggesting that…

P3 – Describe the structure and contraction of different types of muscle. In regards to muscle, there are three main types. These include voluntary (skeletal) muscle, involuntary (smooth) muscle and cardiac muscle. Each have particular functions within the body. One of the main functions which skeletal muscle is responsible for is allowing movement including both fine and gross motor skills to be carried out. Another function which skeletal muscle is required for is protecting an individual’s…

heart from all over the body. The right side of the heart pumps blood to the lungs, where the blood picks up oxygen. The oxygen-rich blood then flows to the left side of the heart through blood vessels (pulmonary veins) and back out to the body. If your child has TAPVR, the pulmonary veins return all the oxygen-rich blood to the right side of the heart instead. The oxygen-rich blood mixes with the returning oxygen-poor blood and passes through a hole between the right side of the heart and the…
