When some function xyz() calls function abc(). all the local variables, static links, dynamic links and function return value goes on the top of all elements of function xyz() in the stack. when abc() exit it's return value has been assigned to xyz().

when a function calls another function then first of all the address of the next statement(next to the calling function) is stored in the stack memory using push and then the control of execution goes to the called function.

when the function 'abc()' calls another function 'xyz()' then first of all, current status of execution is stored in the STACK i.e. the address of current statement (Which lies in Code segment), then all the parameters passed during the call of 'xyz()' (If any) are stored in the STACK then only actual function starts executing. When the function execution completes and control comes at return, then all parameters are popped from the stack followed by the address code and control returns to the current statement.

before the control transfered into the called fucntion(ie. xyz()), the values in some of the registers copied into the stack(registers are : BP,SP,CS,IP,falg).also the values of the local variables are stored into stack and then the control is transfered into the called function xyz(); and before returning from the function xyz() all pushed datas are poped into respective registers and variables.Then the control is transfered into the calling function abc();
