The obturator artery is a branch of the internal iliac artery that passes antero-inferiorly (forwards and downwards) on the lateral wall of the pelvis, to the upper part of the obturator foramen, and, escaping from the pelvic cavity through the obturator canal, it divides into an anterior branch and a posterior branch.
Oxygen (bound to hemoglobin in red blood cells) is the most critical nutrient carried by the blood. In all arteries apart from the pulmonary artery, hemoglobin is highly saturated (95–100%) with oxygen. In all veins, apart from the pulmonary vein, the saturation of hemoglobin is about 75%.
The obturator vein begins in the upper portion of the adductor region of the thigh and enters the pelvis through the upper part of the obturator foramen, in the obturator canal. It runs backward and upward on the lateral wall of the pelvis below the obturator artery , and then passes between the ureter and the internal iliac artery , to end in ...
This change occurs in order to match up the tissue's oxygen demand with the actual oxygen supply available in the blood as closely as possible. [1] For example, if a muscle is being utilized actively, it will require more oxygen than it was at rest, so the blood vessels supplying that muscle will vasodilate, or widen in size, to increase the ...
The obturator membrane is a thin fibrous sheet, which almost completely closes the obturator foramen.. Its fibers are arranged in interlacing bundles mainly transverse in direction; the uppermost bundle is attached to the obturator tubercles and completes the obturator canal for the passage of the obturator vessels and nerve.
The energy derived from the pumping of protons across a cell membrane is frequently used as the energy source in secondary active transport. In humans, sodium (Na + ) is a commonly cotransported ion across the plasma membrane, whose electrochemical gradient is then used to power the active transport of a second ion or molecule against its ...
Foam cells are very small in size and can only be truly detected by examining a fatty plaque under a microscope after it is removed from the body, or more specifically from the heart. Detection usually involves the staining of sections of aortic sinus or artery with Oil Red O (ORO) followed by computer imaging and analysis; or from Nile Red ...
