Relationship between renal system and cardiovascular system?

[dakims]

What are the structural relationships between these two organ systems and what are three renal processes by which blood homeostasis is maintained.

[titilope]

what are the relationship renal and cardiac system , include renal failure, vascular change,hypertention, and chronic cardiac disease

[DoctorStein]

Clue:
- renal system = excretory functions
- cardiovascular system = transportation functions

The transportation system brings waste products and needs a place to filter and to eliminate them.

The obvious relationship is about "renal portal system"

i wonder if I got th question right

it's known that the kidney secrets (( Renin ))

that converts Angiotensin 1 to Angiotensin 2

and it's known also that the final compound is a strong vasoconstrictor

so it will affect the cardiovascular system >>

goodluck
