What do muscle need to order work?

To perform work, muscles require the following substances:

1. Oxygen: Muscles need oxygen to produce energy through the process of cellular respiration. Oxygen is delivered to the muscles by the bloodstream.

2. Glucose: Glucose is a type of sugar that is broken down by the body to produce energy. Glucose is delivered to the muscles by the bloodstream.

3. Amino Acids: Amino acids are the building blocks of proteins. Proteins are necessary for muscle growth and repair. Amino acids are obtained from the breakdown of dietary protein.

4. Electrolytes: Electrolytes are minerals that help to regulate muscle contractions. Electrolytes are obtained from the diet and are also produced by the body.

5. Water: Water is necessary for many bodily functions, including muscle contraction. Water helps to transport nutrients to the muscles and remove waste products.

In addition to these essential substances, muscles also benefit from a number of other nutrients, including vitamins, minerals, and antioxidants. These nutrients help to protect muscles from damage and keep them functioning properly.
