The left semilunar valve, between the left ventricle and aorta, is also called the aortic valve. Muscle tissue known as myocardium or cardiac muscle wraps around a scaffolding of tough connective tissue to form the walls of the heart’s chambers. The atria, the receiving chambers of the heart...
one of the pair of smaller cavities of the heart, with thick muscular walls, from which the blood passes to the ventricles. right atrium - (right side of the heart) receives blood from the superior and inferior vena cava and delivers it to the right ventricle. left atrium receives blood ...
• The left ventricle has even thicker muscular walls than the right ventricle. The left ventricle needs a more powerful contraction to propel blood to the systemic circulation (all of the body apart from the lungs). The right ventricle propels blood to the nearby lungs. The contraction does...
side from the top of the wrapper which consists of four rigidly fixed vertical walls 16 and is open at its upper end and closed at its lower end by a rectangular base plate 18 provided with a bore 20, and units 10 for the position-maintenance of the fuel assemblies 4 in the wrappers ...
Many bacteria and archaea possess a two-dimensional protein array, or S-layer, that covers the cell surface and plays crucial roles in cell physiology. Here, we report the crystal structure of SlpA, the main S-layer protein of the bacterial pathogen Clos

There are two musculofascial abdominal walls; anterolateral and posterior. They attach to the surrounding bony structures; vertebral column, inferior margin of the thoracic cage and superior margins of the bony pelvis. The predominantly soft tissue structure of the abdominal walls gives them the flexib...
Epithelial tissue is found in many locations throughout the body. A few examples include the outside surface of skin, the linings of all digestive organs, the lining of the heart, the inner and outer membranes of the respiratory system, vessel walls, and the internal body cavities. What are...
The top and walls of this chamber are made of wood plates of thickness 6 cm and gravity density γs=5.0×10−4 kg/cm3. The Young’s modulus and Poisson ratio of the wood are assumed as E=1.2×105 kg/cm2 and μ=0.315, respectively. The material properties of the air inside the ...
variations may be seen due to functional differences of arteries and veins. The walls of the arteries are thicker and more muscular and elastic than the veins. This allows it to control the blood flow to different areas of the body and withstand the high pressure of blood leaving the heart....
