    Elements
In summary: So they can easily combine with other elements to form molecules that are essential for life. Na and Ca are in water and this is how they are taken up into plants and animals. K is in soil and this is how it is taken up by plants. In summary, the elements Na, K, and Ca were chosen for their chemical characteristics which make them good at what they do. They are essential for many processes in the body such as bone growth and remodeling, muscle contraction, and Vitamin D absorption.

So why did we end up using the elments that we use for body things? Specifically, Na and K for the channels. Why is it that these two ended up being used? What is it about their chemical characteristics that make them so good at what they do?

Also, with Ca, like you have Ca in your sarcoplasm, and that is what is used in striated muscle contraction (right?), so if you consume a lot of calcium, will it help your muscle strenght? Or I mean, if you don't concume much Ca, will your muscles atrophy? How do you maintain the health of your muscles? How does eating "protein" like in beef make your muscle stronger/better? From what I understand, striated muscle has satelite cells that divide and differentiate into muscle cells to repair injured muscle cells, this is how muscle mass increases with working out. So how does the other stuff (Ca, proteins, etc) fit in? Also, when you flex and unflex, the Ca moves in and out, is it continuously recycled or is sometimes it used up and can't be reused (thus needing more Ca)?

Also, for these ions that the body uses (Na, K, Ca, etc) is this all absorbed in the large intestine? Why is vitamin D neccesary to absorb Ca?

And sharing this love for Ca, what else is it used for in the body? I know its in for bone growth and remodeling, and for muscle contraction, what else?

:) <-- Tons of questions

It is probably that due to our single cell ancestor. These cells evolves in a different environment. The best example and what I known the most about is iron. Iron is one most important thing for virtually all organism (there some few exception in bacteria). The problem is that iron is toxic in the presence of Oxygen. Iron will create free oxygen redicals which cause DNA damage. The iron metabolism was evolved before the atmosphere was 20% oxygen. Iron ion into prevalent oxydated forms (Fe2+ & Fe3+) have great redox potential. Iron is the fourth most abundant element within the Earth's crust. Na, Ca and K are in the top 10 (http://education.jlab.org/glossary/abund_ele.html). The abundance of the ions must have play a role in why these are use so widely in many organisms. Also Na, Ca and K are highly reactive elements.

The reason why Na and K are used for body channels is due to their unique chemical characteristics. These two elements are known as electrolytes, meaning they have the ability to conduct electricity. This is important for the body's channels, as they are responsible for transmitting electrical signals throughout the body. Na and K also have a high affinity for water, which allows them to easily move in and out of cells, regulating their functions.

In terms of calcium, it is essential for muscle contraction as it plays a key role in the release of neurotransmitters that stimulate muscle fibers. Consuming enough calcium can help maintain muscle strength and prevent atrophy, however, it is not the only factor. Adequate protein intake is also important for muscle health as it provides the necessary building blocks for muscle repair and growth. In addition, regular exercise is crucial for maintaining muscle mass and strength.

As for the recycling of calcium, it is continuously used and replenished in the body. However, if there is a deficiency in calcium intake, the body may start to break down bone tissue to maintain calcium levels, leading to weaker bones and potentially affecting muscle health as well.

The absorption of these ions (Na, K, Ca) does not solely occur in the large intestine, but rather throughout the digestive system. Vitamin D is necessary for the absorption of calcium as it helps regulate the levels of calcium and phosphorus in the body, which are essential for bone growth and maintenance.

Aside from bone and muscle health, calcium also plays a role in blood clotting, nerve signaling, and hormone secretion. It is also involved in maintaining proper blood pressure and heart rhythm.

Overall, the body uses these ions for various essential functions and maintaining a balance of them is crucial for overall health and well-being.
 

1. Why are sodium and potassium important for body channels?

Sodium and potassium are important for body channels because they are electrolytes that help regulate the flow of electric signals in and out of cells. These signals are crucial for various bodily functions such as muscle contractions, nerve impulses, and maintaining the body's water balance.

2. What are the main uses of sodium and potassium in the body?

The main uses of sodium and potassium in the body include regulating blood pressure, maintaining nerve and muscle function, and balancing fluid levels. They also play a role in the absorption and transportation of nutrients and waste products in and out of cells.

3. How do sodium and potassium benefit the body?

Sodium and potassium benefit the body by helping to maintain proper hydration and electrolyte balance. They also aid in the transmission of nerve impulses, which is essential for muscle contractions and other bodily functions. Additionally, these minerals play a role in maintaining healthy bones and preventing conditions such as high blood pressure and heart disease.

4. What are some food sources of sodium and potassium?

Sodium can be found in table salt, processed foods, and some natural foods such as celery and beets. Potassium can be found in fruits, vegetables, dairy products, and legumes. Some good sources of potassium include bananas, avocados, potatoes, and spinach.

5. Can a deficiency or excess of sodium and potassium be harmful?

Yes, a deficiency or excess of sodium and potassium can be harmful. Too much sodium can lead to high blood pressure, while too little can cause low blood pressure and other health issues. Similarly, an imbalance of potassium can also have negative effects on the body, such as muscle weakness and irregular heart rhythms. It is important to maintain a balanced intake of these minerals through a healthy diet and to consult a healthcare professional if you have any concerns about your sodium and potassium levels.
