Right ventricle
Explanation
Systemic circulation is the flow of blood from the left ventricle of heart to all parts of body and return of blood to the right atrium of heart. The oxygenated blood leaves the left ventricle through aorta and deoxygenated blood returns to the right atrium through superior and inferior vena cava. The purpose of systemic circulation is to transport oxygen and nutrients to body tissues and remove carbon dioxide and other wastes. Hence, systemic circulation of oxygenated blood starts from left ventricle.
So, the correct answer is 'Left ventricle'.

Leukaemia
Explanation
Leucopenia is the decrease in WBCs (white blood cells) in the blood.
This increases the chances of infection in body. WBCs are involved in the immunity of body and destroy foreign pathogens and particles.
However, the number of WBCs may also decrease due to acute infection and this leads to weak immunity.
Leucopenia have further subtypes depending upon which type of leucocytes are decreasing.
There are five types of leucocytes in our body, basophils, eosinophils, neutrophils, lymphocytes and monocytes.
If there is decrease in count of neutrophils, the condition is known as neutropenia. Most often, leucopenia occurs due to fall in neutrophils cells.
So, the correct answer is 'Leucopenia'.

Single circulatory system.
Explanation
The correct answer is option A.
The cardiovascular system is composed of two circulatory paths: pulmonary circulation, the circuit through the lungs where blood is oxygenated; and systemic circulation, the circuit through the rest of the body to provide oxygenated blood. The two circuits are linked to each other through the heart, creating a continuous cycle of blood through the body.
Pulmonary circulation: The part of blood circulation which carries oxygen-depleted blood away from the heart, to the lungs, and returns oxygenated blood back to the heart.
Systemic circulation: The part of blood circulation that carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.

What is correct regarding blood pressure?
Report Question
0%
105/50 mm Hg makes one very active
0%
100/55 mm Hg is considered at ideal blood pressure
0%
190/110 mm Hg may harm vital organs like brain and kidneys
0%
130/90 mm Hg is considered as high and requires treatment
Explanation
Blood pressure 190/110 mm Hg indicates high blood pressure or hypertension. Normal systolic and diastolic blood pressure in body is 140 mm Hg and 90 mm Hg respectively. Pressure above 140 mm Hg and 90 mm Hg is high blood pressure which can cause damage to vital organs like brain and kidney. High blood pressure can cause damage to blood vessels in brain and kidney. This can lead to rupture of blood vessels and cause brain haemorrhage. In kidneys, high blood pressure can lead to inadequate supply of blood to kidney and thus, resulting in decreased filtration.
So, the correct answer is '
190/110 mm Hg may harm vital organs like brain and kidneys'.

Neutrophil
Explanation
White blood cells or leukocytes can be granular or agranular depending upon the presence or absence of granules in their cytoplasm.
Granulocytes are granular leukocytes and are of three types:
Eosinophils: These cells play important role in immunity and allergic reactions.
Basophils: These cells secrete histamine, serotonin and heparin.
Neutrophils: These cells perform phagocytosis.
Agranulocytes are non-granular leukocytes and are of two types:
Lymphocytes: These cells produce antibodies.
Monocytes: These cells are phagocytic.
So, the correct answer is 'Lymphocyte'.
