Target angle submarine observer estimating target angle pictures himself on the target ship looking back at the submarine. Relative bearing of the submarine is the clockwise angle in degrees from the heading of the target ship to a straight line drawn from the target ship to the submarine. When target angle is 0° (or 360° ) the target ship is coming directly toward the submarine. Target angles between 0° and 90° indicate the target ship is moving toward and to the right of the submarine. Target angles between 90° and 180° indicate the target ship is moving to the right and away
Venous angle Venous angle Venous angle (Pirogoff's angle, Latin: "angulus venosus") is the junction of the internal jugular (latin: v. jugularis interna) and subclavian (latin: v. subclavia) veins at both sides of the neck. The external and the anterior jugular and the vertebral veins converge toward it. The left venous angle receives lymph from the thoracic duct (ductus thoracicus). The right venous angle receives lymph from the right lymphatic trunk (truncus lymphaticus). Truncus lymphaticus is only about 1 cm long and conveys lymph from the right side of the thorax (including parts of the liver) as well as the right arm and
