Question
Calcium in the diet of a teenager is actively absorbed in the small intestine and transferred into the intestinal capillaries.

1. I'm not too sure how to describe the route this calcium would follow to end up in the upper arm.

2. Having trouble describe the role of calcium at the neuromuscular junction and its role in muscle contraction and relaxation in triceps brachii.

3. I also have trouble with the function of calcium in bone growth and explaining how the humerus would grow in length from this.

Thanks in advance for the help! So confused :/
