Which of the following processes is directly affected by the cardiovascular system?

hair growth

muscle strength

healing of cuts

hormone release

Verified Answer :

Although the cardiovascular system affects all of these processes of course, it directly affects the healing of cuts, because it transports red blood cells to the wound site.

The correct answer is option D, hormone release

Reason-

The cardiovascular system (CVS) comprises of three main components – heart, blood and blood vessel. The major functions of CVS are

a) To carry and parcel nutrients, hormones and oxygen to each cell in the entire body.  

b) To regulate fluid balance in the body

c) To protect body from blood loss and infection

As it is clear from the functions of CVS, harmones  are transported and released at different body location. This can be considered as a direct function of blood while in order to prevent blood loss,  blood platelets become functional at injury regions and this becomes a secondary function.
