Answer 1

ANSWERS:

Question 1.

The Right Atrium receives deoxygeneted blood from :

Option Superior Vena Cava is correct. The Superior Vena Cava is located in the upper chest region. These veins brings deoxygenated blood from the upper body regions including the head, neck, arm and chest regions of the body to the Right Atrium of the heart.

Option Aorta is incorrect, because the aorta is the largest artery in the body which carries oxygenated blood away from the heart to rest of the other organs. Also aorta is originated from the left ventricle of the heart and extending down to abdomen.

Option Right Pulmonary Veins is also incorrect, because they are the blood vessels that carry oxygenated blood from the lungs back to the heart

Option Inferior Vena Cava is Correct. The Inferior Vena Cava is formed by the joining of the common iliac veins located in the posterior abdominal wall. These veins drain deoxygenated blood from the lower body regions including legs, back, abdomen and pelvis into the Right Atrium of the heart.

Question 2.

Anatomical Structure responsible for the Electrical Impulse:

Option Purkinje Fibers is Correct. These are responsible for the electrical impulses, because Purkinje fibers are the part of the conducting system of the heart, which intiates and coordinates the electrical signals of the heart.

Option Bundle of His is Correct. This is also a part of the electrical conduction system of the heart because it transmits impulses from the atrioventricular node to the ventricles of the heart.

Option Sinoatrial Node is also Correct, because this is also a part of the electrical conduction system of the heart. This sinoatrial node controls the heart rate. It is also called as Pacemaker of the heart and also known as (SA node).

Option Atrioventricular Node is also Correct. This is also a part of the electrical conduction system of the heart. This is responsible for the conduction of electrical impulses from the atrium to the ventricles of the heart.

Question 3:

Fluid in the Pericardial Sac :

Option Inflammation of the Pericardium is Correct. The Fluid in the Pericardial sac cause inflammation/infection . This cause Pericarditis of the pericardial sac.

Option Blood in the Pericardial Sac is also Correct, because the fluid in the pericardial sac causes inflammation and injury in the lining of the pericardium. This can cause forming of the blood in the pericardial sac.

Option Elevated Triponin levels is also Correct, because fluid in the pericardial sac cause infection or inflammation of the pericardial sac, known as Pericarditis. This pericarditis can cause injury of the muscle layers of the heart. This condition cause the increase of the Troponin levels in the serum blood.

Question 4:

Secondary Hypertension is :

Option Hypertension from a known cause is Correct, because secondary hypertension is a type which is caused by some other medical conditions such as diseases in the kidneys, liver, arteries, etc.

Option Hypertension from an unknown cause is incorrect, because secondary hypertension has a cause. Only the Primary Hypertension may be affected by unknown cause.

Option Hypertension from hereditary triats is Incorrect in the case of Secondary Hypertension, because secondary hypertension is mainly caused by some medical conditions.

Option Hypertension from an Increased Blood Viscosity is Incorrect in the case of Secondary Hypertension, because this hypertension has an identifiable causing factor. This option is related to Primary Hypertension because it influences the work of heart pumping and also related with the atherosclerosis and atherothrombosis conditions.
