What is the endocrine system? What is it for? What is the lymphatic system? What is the main purpose of the urinary system?

7,   Which of the following negative feedback loops contains a proper response to a drop in blood pressure?   Multiple Choice   angiotensin II activation -> rise in aldosterone -> increased in Na+ reabsorption -> increased renin production -> increased water reabsorption -> increase in blood volume   increase in Na+ reabsorption -> rise in aldosterone -> angiotensin II activation -> increased renin production -> increased water reabsorption -> increase in blood volume   angiotensin II activation -> rise in aldosterone -> increased in K+ secretion -> increased renin production -> increased water reabsorption -> increase in blood volume   increased renin production -> angiotensin II activation -> rise in aldosterone -> increased in Na+ reabsorption->increased water reabsorption ->increase in blood volume

What did you learn about the uses of homeostasis?  3 - Three things I learned about how homeostasis is used in the body:2 - Two other things I found interesting about homeostatic processes:1 - One question I still have: Using good Self-Regulation skills, check over your map of the steps in urine formation. Your flowchart should include these concepts and details: location in the nephron where the reactions occur, the types of substances moving into or out of the nephron, vocabulary and terminology that allow you to demonstrate your understanding. Ask yourself these big questions as a way to monitor and improve your work: Is the information I have presented a complete representation of my learning? Is the information I have presented correct? Have I fulfilled the requirements of the task? Are the steps I describe organized in the correct order? you can get the information from these video:   https://youtu.be/vNvZaGcLzEo

Im not sure if I am doing this right and I need some help, thank you.
