Where on the thoracic surface do you auscultate the tricuspid mitral pulmonary and aortic valves?

∙ 10y ago
The heart sounds are heard at something called the 4 corners of the chest around the sternum.
1) the aortic valve is heard at the 2nd intercostal space at the right sternal margin.
2) the pulmonary valve is heard at the 2nd intercostal space at the left sternal margin.
3) the mitral valve is heard over the heart apex which is in the 5th intercostal space in line with the middle of the clavicle.
4) the tricuspid valve is typically heard in the right external margin of the 5th intercostals space.

Why is the ventral surface of a thoracic cavity firmer that the surface of the abdomen of a rat?
The thoracic cavity is stiffened by the ribcage and the muscles associated with breathing. This forms a flexible but comparatively firm surface.
The double membrane that covers the lungs and lines the thoracic cavity is?
Pleura is the double membrane that cover and line in the thoracic cavity.
What covers the inner surface of the thoracic wall?
ciliated epithelium
What percentage of the alveolar surface is covered with pulmonary capillaries?
99%
How many articular surface are on each vertebrae?
The thoracic vertebrae have 6 and all the others have 4.
What is pleural linkage?
There are 2 types of pleura in the thoracic cavity. Visceral pleura which covers the lungs and parietal pleura which covers the inner surface of the thoracic cage. These 2 pleurae form a sac which encases the lungs, the surface tension of the fluid links the lungs and thoracic cavity together aka pleural linkage, which allows the lungs and thorax to operate together as one unit.
What supply blood to the lungs?
The left and right bronchial arteries supply blood to lung tissue. Don't confuse these with the pulmonary arteries. The pulmonary a.a. carry deoxygenated blood ultimately to the capillary network of the alveoli for gas exchange but these vessels DO NOT supply blood to the lungs themselves. And the key word is "supplies". There are two left bronchial a.a. that arise from the superior surface of the thoracic aorta and a single right bronchial a., which can arise from either a posterior intercostal a. or from the superior left bronchial a. The bronchial a.a. branch off into bronchopulmonary a.a., which are different from the pulmobronchial a.a. that branch off the pulmonary a.a.
What is the process of blood thew the heart?
Deoxygenated blood is returned through the veinous system to the heart. The superior and inferior vena cava terminate in the right atrium, which pumps the blood into the right atrium. From here it goes out the pulmonary trunk to the pulmonary arteries. It enters the lungs and exchanges the CO2 for O2. Oxygenated blood is returned to the left atrium via the pulmonary vein. It moves from left atrium to left ventricle, where it is pumped into the aorta and arterial network. The tricuspid valve operates between right atriuam and right ventricle. The pulmonary valve operated between the right atrium and pulmonary circulation. The mitral valve operates between the left atrium and left ventricle. The aortic valve operates between the left ventricle and systemic circulation. Remember: The systemic circulation is high pressure (~120/80), but the pulmonary system is comparitively low pressure (~20/5), as it has such a wide surface area of flow.
What articular surfaces are unique to the thoracic vertebra?
The surface that articulates with the ribs which is simply called the the "Demi-Facet" for the head of the rib. There is also a part on the transverse process of the thoracic vertebrae which acts as a block to prevent the rib from moving posteriorly.
What surface articulates Inferior process of the superior thoracic vertebrae?
There is no inferior process on any vertebrae, thoracic or not. There is an inferior articular facet. The inferior articular facet would articulate with the superior articular facet of the vertebrae just superior to it.
What is the normal valve area of the pulmonary valve?
2 square cm\meter square of body surface area.
Name of surfactant that breaks surface tension in the lungs?
Am pretty sure its called the pulmonary surfactant that's produced from the lungs
