  1. Jan 18, 2010 · Once you are familiar with your organ's stop action, it's time to pull out the stop list you compiled in Before We Begin: Acquiring the Essentials. You'll notice that in addition to the names of the stops, two different kinds of numbers are also present.

  2. Since the electrical stimulus begins at the apex, the contraction also begins at the apex and travels toward the base of the heart, similar to squeezing a tube of toothpaste from the bottom. This allows the blood to be pumped out of the ventricles and into the aorta and pulmonary trunk.

    The blood from the heart is carried through the body by a complex network of blood vessels (Figure 1). Arteries take blood away from the heart. The main artery is the aorta that branches into major arteries that take blood to different limbs and organs. These major arteries include the carotid artery that takes blood to the brain, the brachial arte...

    Blood is pushed through the body by the action of the pumping heart. With each rhythmic pump, blood is pushed under high pressure and velocity away from the heart, initially along the main artery, the aorta. In the aorta, the blood travels at 30 cm/sec. As blood moves into the arteries, arterioles, and ultimately to the capillary beds, the rate of ...

    Blood pressure (BP)is the pressure exerted by blood on the walls of a blood vessel that helps to push blood through the body. Systolic blood pressure measures the amount of pressure that blood exerts on vessels while the heart is beating. The optimal systolic blood pressure is 120 mmHg. Diastolic blood pressure measures the pressure in the vessels ...

    Cardiac output is the volume of blood pumped by the heart in one minute. It is calculated by multiplying the number of heart contractions that occur per minute (heart rate) times the stroke volume(the volume of blood pumped into the aorta per contraction of the left ventricle). Therefore, cardiac output can be increased by increasing heart rate, as...

  3. Blood primarily moves in the veins by the rhythmic movement of smooth muscle in the vessel wall and by the action of the skeletal muscle as the body moves. Because most veins must move blood against the pull of gravity, blood is prevented from flowing backward in the veins by one-way valves.

  4. Hemostasis has four key steps in stopping bleeding; Vasoconstriction: Blood vessels constrict to slow blood flow. Primary hemostasis: Platelets clump together, forming a sticky plug to fill the wound. Secondary hemostasis: Fibrin strands weave a mesh, reinforcing the clot. Fibrinolysis: Plasmin enzymes dissolve the clot when healing is complete.

  5. An organ stop is a component of a pipe organ that admits pressurized air (known as wind) to a set of organ pipes. Its name comes from the fact that stops can be used selectively by the organist; each can be "on" (admitting the passage of air to certain pipes), or "off" ( stopping the passage of air to certain pipes).

  7. Sep 4, 2023 · Primary Hemostasis. Primary hemostasis is the formation of a weak platelet plug which is achieved in four phases: vasoconstriction, platelet adhesion, platelet activation, and platelet aggregation. Vasoconstriction is the initial response whenever there is vessel injury.
