Homework Answers
The statement is false because during inspiration negative pressure will be created in thoracic cavity.
The negative pressure in thoracic cavity exerts negative pressure on superior vencava and inferior venacava . This makes more blood to return to the heart ( right) during inspiration.
Thus negative pressure makes increased venous return to the heart .
