Vasodilation
Renin Angiotensin Aldosterone System Decrease in blood flow (hypoxia) à decrease in oxygen in the kidney à kidney secretes 1. __________ à reaches the liver to secrete 2. _______________ à goes back to the blood stream. Blood brings it to the lungs which has 3. ________________ . The role of (#3) is to 4. ___________________________ à which is a potent vasoconstrictor if it binds to 5. ___________________ in blood vessels. This results to an increase in 6. ______________________ which will lead to an increase in 7. _____________________. Blood flow increases in the kidney, which will stop producing Renin. There is also an angiotensin 2 receptor in the 8. ____________________, where angiotensin 2 may also bind, leading to the production of 9. ______________________, which retains 10. _____________ and excretes potassium. Since sodium loves 11. _____________________, there is a further increase in 12. ________________ which further increases total peripheral resistance and blood…
