I have learned so much this year through anatomy and physiology its not even right...
Our kidneys are what controls the major work for our urinary system. It is major pathways and storage areas as well. Key functions of the kidneys are:
1) Regulation of blood ionic composition. Which means it takes care of the most important electrolytes in our body... like sodium ions, potassium ions, and calcium ions!
2) Regulation of blood pH. If we do not have a pH of 7.35-7.45 we are in a coma if not dead... very important.
3) Regulation of blood volume. Kidneys will control our volume of blood by conserving or elimination water in the urine.
4) Regulation of blood pressure!!! (We learned all about this in lecture last day of class!!! Won't forget it Dana ;) ) Kidneys help regulate blood pressure by secreting the enzyme renin which activates the renin-angiotensin-aldosterone pathway.
5) Production of hormones! We all know we need these bad boys... Kidneys produce Calcitriol which is the active form of vitamin D helping to regulate calcium homeostasis and it produces erythropoietin which stimulates production of red blood cells that we need LOTS OF!
6) Excretion of wastes and foreign substances. Kidneys help excrete wastes that have no value what so ever for our body. We mide as well piss em' out right?
Our Kidneys are so important they only take up 0.5% of our body mass if that... and receive 20-25% of the resting cardiac output!!! In adults renal blood flow is almost 1200 mL per minute. Whoa bettsy...
This information relates to me in my everyday life because... for one I got two kidneys :) and its nice to know why I have them, and what they are capable of doing. I learned also this very day that I can survive with just one, but I think I knew that because I know 2 NBA stars had to have kidney transplants due to a rare kidney disease (Alonzo Mourning & Sean Elliott). Also as a Surgical Technician I thrive to know as much as I can, and kidneys play a big role in peoples lives and answers questions to when people are sick.

I think that I might have found a solution to my problem. For the past few months I have had high blood pressure. I thought that it could be from a number of reasons (b.c., smoking, stress, etc.), until I learned that I just need to go pee more often. I am a germaphobe so I tend to only go pee 2-3 times per day. Morning, noon, and night. I have learned that I need to get over my germaphobia and go pee more often!!! And this will be beneficial to my health :) So I have been making an effort to pee more often than not, and as a result... I have noticed a difference.
ReplyDeleteI too found that the kidneys were fascinating!! I never really thought about how it was that we generate urine or even where it came from until I learned it in class. The kidney's definetly play a huge role in our bodies and carry out numerous functions. Although it is possible to live with just one functioning kidney, it is nice to know that so far both of mine work properly:) I think I would rather not lose one of them at all!! I also had no idea that the kidneys were responsible for the regualtion of our blood pressure either...so that could by why when I was pregnant my blood pressure was slightly higher, and with that in mind it could also be why I had to pee so much haha :)
