Answer:

4

Explanation:

A-Right atrium

B-Left atrium

C-Left ventricle

D-Right ventricle

Answer 2

The boxes above are representing chambers of  : Human heart please note that mitral valve is located between chamber 'B' and 'C' :

• The valve between the right ventricle and right atrium is the tricuspid valve, and the one which is found between the left ventricle and left atrium is known as the mitral valve.
• Semilunar valves are located between the left ventricle and aorta.
• It is also found between the pulmonary artery and right ventricle.
• Also Read: Blood and its Composition.
• Chamber 'D' contains deoxygenated blood.
• The four chambers are right atrium, right ventricle, left atrium and left ventricle.
• The working of the heart includes:
• Right auricle receives deoxygenated blood and pumps it to the right ventricle.
• Later, it is pumped to the heart for purification.

Valve located at outlet of chamber 'B' is semilunar valve :

• Semilunar valves : The semilunar valves are flaps of endocardium and connective tissue reinforced by fibers which prevent the valves from turning inside out.
• They are shaped like a half moon, hence the name semilunar (semi-, -lunar).
• The semilunar valves are located between the aorta and the left ventricle, and between the pulmonary artery and the right ventricle.

Semilunar Valves 1 Pulmonary Valve :

• This heart valve is located between the right ventricle and pulmonary artery.
• When closed, it prevents... 2 Aortic Valve: This heart valve is located between the left ventricle and aorta.

Lungs are located between chamber 'C' and 'D' :

• The lungs are situated in the thoracic chamber which is anatomically an air-tight chamber.
• The anatomical setup of lungs in thorax is such that any change in the volume of the thoracic cavity will be reflected in the lung (pulmonary) cavity.
• Such an arrangement is essential for breathing, as we cannot directly alter the pulmonary volume.

Coronary sinus opens in chamber 'D' Call :

• The coronary sinus empties directly into the right atrium near the conjunction of the posterior interventricular sulcus and the coronary sulcus (crux cordis area), located between the inferior vena cava and tricuspid valve; this atrial ostium can be partially covered by a thebesian valve, although the anatomy of this valve is highly variable.
