Vedclass · Answer

(B) Blood pressure is influenced by various physiological factors. $1$. Length of blood vessel: Increased length increases resistance,which increases blood pressure. $2$. Vasoconstriction: Narrowing of blood vessels increases resistance and thus increases blood pressure. $3$. Venous return: Increased venous return increases stroke volume and cardiac output,leading to higher blood pressure. $4$. Atrial Natriuretic Factor $(ANF)$: $ANF$ is released by the atrial wall in response to increased blood pressure. It causes vasodilation and promotes sodium excretion by the kidneys,which reduces blood volume and consequently lowers blood pressure. Therefore,blood pressure is inversely related to the level of $ANF$.

Blood pressure is directly proportional to the following $EXCEPT$ . . . . . . .
