Answer 1

Question 1

                 The great saphenous vein is a large venous blood vessel running near the inside surface of the leg from the ankle to the groin. It arises from the dorsal venous arch at the top (dorsum) of the foot and drains into the femoral vein, the main deep vein for the leg.

               The greater Saphenous vein is used for an autograft because:

v Graft has been in use for many years

v Vein grafts are placed in a reversed position to allow free blood to flow via the venous valves.

v Saphenous vein graft (SVG) remains patent for more than a ten-year period

Question 2

During closure of a Median Sternotomy ,the surgeon may use sternum wires (Stainless steel wires) to close the sternum.

Question 3

Fusiform Aneurysm is An outpouching or widening of an artery or a vein that is shaped like a spindle.

Question 4

Saccular aneurysm also called “berry” aneurysms because they look like berries, are the most common type of brain aneurysm. Saccular aneurysms have a “neck” that connects the aneurysm to its main (“parent”) artery and a larger, rounded area called the dome. These aneurysms bulge on only one side of the artery wall.

Question 5

The cardiac cycle is the sequence of events that occur when the heart beats. The cycle has two main phases: diastole, when the heart ventricles are relaxed, and systole, when the ventricles contract. One cardiac cycle is defined as the contraction of the two atria followed by contraction of the two ventricles.

Question 6

Ventricular Systole is the contraction, or period of contraction, of the heart, especially of the ventricles, during which blood is forced into the aorta and pulmonary artery. Ventricular systole contraction of the ventricles, forcing blood into the aorta and pulmonary artery.

Question 7

Diastole is the phase of the heartbeat when the heart muscle relaxes and allows the chambers to fill with blood.

Question 8

The heart is enclosed by a double layered membrane called the Pericardium.

Question 9

The Heart muscle is called the Myocardium (Cardiac Muscle).

Question 10

Valve leaflets are attached to the papillary muscles by Chordae tendineae.
