Given these pressures, in which direction will blood flow? Right atrium 2mmHg Left atrium 5mmHG Right ventricle 0mmHg Left ventricle 2mmHg A. From the ventricles to the atria B. From the atria to the ventricles C. From the left atrium to the right atrium D. From the left ventricle to the right ventricle 8. Which events occur as a result of ventricular systole?
It starts with oxygen poor blood being pumped from the right ventricle into the pulmonary trunk. The pulmonary trunk divides into right and left pulmonary arteries that subdivide into the lobar arteries in the lungs. The lobar arteries accompany the main bronchi into the lungs and then branches forming arterioles and then pulmonary capillaries that cling to alveoli. Here oxygen moves from the air sacs to the blood, and carbon dioxide from the blood moves to the air sacs. Next, the pulmonary capillary beds drain into venules which join to form two pulmonary veins exiting each lung.

http://www.healthline.com/human-body-maps/tricuspid-valve The Pulmonic Valve: This valve is found between the right ventricle and the lungs. As the deoxygenated blood continues on its journey through the heart from the right ventricle, it makes its exit by way of the pulmonic valve. This structure is a one-way valve with prevents the flow of blood back into the right ventricle once it leaves the heart. http://www.healthline.com/human-body-maps/pulmonary-valve The mitral valve: This valve is located between the left atrium and the left ventricle. As the now oxygenated blood flows back through the left atrium, it does so under increased pressure.
The serous membrane secretes serous fluid into the space between the visceral and parietal layers that allows smooth movement between the layers, when the heart beats. The Myocardium: The myocardium is the middle layer of the heart and is composed of specialised muscle tissue called as the cardiac muscle, on which the circulation of blood depends. It varies in thickness, being thickest in the left ventricle, thinner in the right ventricle and thinnest in the artrium. The Endocardium: The endocardium forms the inner linging of the heart is a thin, smooth, glistening membrane consisting of flattened epithelial cells which is continuous with the valves and with the lining of the blood
Blood from the left side of the body is also making its way to the lower lobe of the lung from this route. The inferior vena cava is the largest vein in the body. This vein will dump us into the right atrium of the heart. Look! I can already see the heart.
An LHD-1 level a phenomenon known as ‘flipped LDH’, Is strongly indicative of a Heart attack. 6. What pathophysiology occurs during a myocardial Infarction? Include all four processes. Most Myocardial Infarctions are caused by a disruption in the vascular endothelium associated with an unstable atherosclerotic
The heart consists of 2 ventricles, and also 2 atria. There is a right atrium and also ventricle, this is where the blood comes from the veins. The deoxygenated blood then goes into the right atrium of the heart. Blood is released from the atrium and goes into the right ventricle, this happens when the heart relaxes, this is where the right ventricle pushes blood in through pulmonary valve and eventually into pulmonary artery, this is the place where the blood its given to the lungs because to get back oxygen. Lastly the blood is then given back to hearts left side.
2. Insert a glass rod into the pulmonary artery and see it come through to the right ventricle. Make an incision down through this artery and look inside it for three small membranous pockets. These form the pulmonary semi-lunar valves which prevent blood from flowing back into the right ventricle. 3.
