Blood flow
horrorfan [7]

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.

guajiro [1.7K]

Answer:

C) It has a long preganglionic fibers

Explanation:

Peripheral nervous system (PNS) is the nervous system that contains nerves and ganglia outside the central nervous system (CNS). PNS is divided into:

  1. somatic (voluntary) nervous system-controls the movements of the skeletal muscles
  2. autonomic (involuntary) nervous system-controls the smooth muscles and glands and thus it is the regulator of the major body functions. It is subdivided into tree groups:
  • sympathetic ("fight and flight") system-responsible for stressful and active situations (but also in normal conditions);contains short preganglionic fibers and long postganglionic fibers.
  • parasympathetic ("rest and digest") system-opposite to sympathetic, responsible for the maintenance of body's activities at rest.
  • enteric nervous system-controls the function of the gastrointestinal tract.
