Q.1
Largest internal vein from alimentary canal to liver is ... ... [ RPMT 2006 ]
0%
a) Aorta
0%
b) Hepatic artery
0%
c) Hepatic vein
0%
d) Hepatic portal vein
Explanation
The hepatic portal vein: is a vessel that moves blood from the spleen and gastrointestinal tract to the liver. It is approximately three to four inches in length and is usually formed by the merging of the superior mesenteric and splenic veins behind the upper edge of the head of the pancreas. In some individuals, the inferior mesenteric vein may enter this intersection instead. The aorta: is the main artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen. Hepatic artery: is a short blood vessel that supplies oxygenated blood to the liver, pylorus of the stomach, duodenum and pancreas. Hepatic veins: are the veins that drain de-oxygenated blood from the liver into the inferior vena cava. Answer : (d)

0%
d) Pulmonary trunk
Explanation
In order of blood flow, the pulmonary arteries start as the pulmonary trunk or main pulmonary artery. The pulmonary artery carries deoxygenated blood from the heart to the lungs. In the human heart, the pulmonary trunk begins at the base of the right ventricle. It is short and wide—approximately 5 centimetres in length and 3 centimetres in diameter. It then branches into two pulmonary arteries, which deliver deoxygenated blood to the corresponding lung. Answer : (d)

0%
a) Systolic pressure
0%
b) Diastolic pressure
0%
c) Lubb
0%
d) Dup
Explanation
At each heartbeat, blood pressure is raised to the systolic level, and, between beats, it drops to the diastolic level. As the cuff is inflated with air, a stethoscope is placed against the skin at the crook of the arm. As the air is released, the first sound heard marks the systolic pressure; as the release continues, a dribbling noise is heard. This marks the diastolic pressure, which is dependent on the elasticity of the arteries. Answer : (a)

d) High level of HDL
Explanation
Arteriosclerosis is the thickening, hardening and loss of elasticity of the walls of arteries. This process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis. It’s the usual cause of heart attacks, strokes, and peripheral vascular disease. Vasomotion: is the spontaneous oscillation in tone of blood vessels, independent of heart beat, innervation or respiration. HDL: high-density lipoprotein, is associated with levels of cholesterol in the body. HDL levels are important in predicting risk of heart disease. Answer : (c)
