The lungs supplies the bloodstream with oxygen. When we breathe in, out lungs fill with oxygen and that oxygen is taken to the heart to keep our body going.

After being absorbed in the small intestine, glucose enters the bloodstream and is transported to the liver. The liver releases glucose into the bloodstream as needed, and it travels to the leg muscle cells through the circulatory system. Once in the muscle cell, glucose is used as an energy source through cellular respiration.
The path followed by the blood when it supplies and drains the heart muscle
The musculocutaneous nerve pierces the coracobrachialis muscle and supplies it with innervation.
Muscle, and gravity
glucose
Yes, animals can build muscle through exercise and physical activity. Just like humans, animals can increase muscle mass and strength by engaging in regular physical activity and exercise.
During respiration, glucose is delivered to muscle cells primarily through the bloodstream. After carbohydrates are digested, glucose is absorbed into the bloodstream from the intestines and transported to various tissues, including muscles. Insulin, a hormone produced by the pancreas, facilitates the uptake of glucose into muscle cells by promoting the translocation of glucose transporters to the cell membrane. Once inside, glucose is metabolized to produce ATP, the energy currency needed for muscle contraction.
