Of course it is! Didn't you get your Ph.D. in Nuclear Physics?

The Parathyroid hormone has a decrease in plasma calcium. It uses a Pentagastrin as stimulation for its release.
Ions: sodium, chlorine, pottasiu, calcium; buffers and osmoregulators; also hormones are transported in the blood plasma.
In endocytosis, transported substances are enclosed in vesicles formed from the plasma membrane, which do physically cross the plasma membrane. These vesicles then transport the substances into the cell.

Parathyroid hormone (PTH) primarily increases plasma calcium levels by promoting calcium release from bones, enhancing intestinal absorption of calcium, and increasing renal tubular reabsorption of calcium. A mechanism that would NOT alter plasma calcium levels would be the direct inhibition of calcium absorption in the intestines, as this would decrease calcium availability rather than increase it. Additionally, any process that solely focuses on decreasing calcium excretion without affecting bone resorption or intestinal absorption would also not effectively raise plasma calcium levels.
Glucose is carried through the circulation in the blood plasma.
In plasma, iron is transported bound to a protein called transferrin. Transferrin helps to deliver iron to cells throughout the body, where it is necessary for various biological functions.
Nutrients are transported in the plasma because they need to be carried throughout the body to reach various tissues and organs where they are needed for energy production, growth, and maintenance. The plasma is the fluid component of blood that allows for the efficient circulation of nutrients to different parts of the body.
