Lymphatic Filariasis is caused by a

• Parasite Infection

• Bacteria

• Virus

• Physical Injury

Multiple Choice

Through the coordination of which systems do the human muscular tissues obtain nutrients from the external environment?

• Digestive system and respiratory system

• respiratory system and circulatory system

• digestive system and circulatory system

Arterial wall is made of :

• Innermost layer (thin and smooth epithelial tissues)

Multiple Choice

The heart beats by itself (myogenic) because the heart has specialised cardiac muscle fibres which make up the cardiac conductive system. In this system, impulses are transferred in the sequence:

• sinoatrial node, atrioventricular bundle, atrioventricular node, Purkinje fibres

• atrioventricular node, sinoatrial node, atrioventricular bundle, Purkinje fibres

• sinoatrial node, atrioventricular node, atrioventricular bundle, Purkinje fibres

Multiple Choice

The main cause of coronary heart disease is ...

• the lesions on the heart due to viral infection

• emotional stress caused by hectic work and lifestyle

Multiple Choice

The wall of the left ventricle is thicker than that of the right ventricle because

• the left atrium sends out more blood than right atrium

• the lumen of the aorta is smaller than the lumen of the pulmonary artery

• the blood sent out by the left ventricle travels further than the right ventricle

• the right ventricle has a larger lumen than the left ventricle
