Respiratory and circulatory systems work hand in hand to expel wastes. respiratory system removes CO2 and the circulatory uses the blood as a medium to move excess salts and water from source to sink.
Answer:
D. Tricuspid → right ventricle → pulmonary valve → pulmonary circulation
Explanation:
The circulatory system is the system of organs and blood vessels which is associated with the circulation of the blood in the body.
The circulatory system is divided into two portions: the systemic circulatory system (body) and the pulmonary circulatory system (lungs).
The vena cava brings the oxygen-poor blood from the body to the right atrium from where the blood is transferred to the same side of the ventricle controlled by the tricuspid valve (atrioventricular valve).
From the right ventricle, the blood is pumped to the pulmonary artery which transports the blood to the lungs where the oxygen will be exchanged.
Thus, Option-D is correct.
