To rank these items from smallest to largest, we need to consider their size or scale. Let's go through each item and determine their relative sizes:

1. Electron: Electrons are subatomic particles and considered to be one of the smallest constituents of matter. They are tiny, approximately 1/1836th the size of a proton or neutron.

2. Hydrogen atom: A hydrogen atom consists of a single proton and an electron. It is larger than an electron but still quite small compared to macroscopic objects.

3. Sodium atom: Sodium is a larger atom compared to hydrogen as it contains more protons, neutrons, and electrons. However, it is still relatively small in the grand scale of things.

4. Carbon atom: Carbon atoms are slightly larger than sodium atoms as they contain six protons, six neutrons, and six electrons.

5. Nucleotide: Nucleotides are the building blocks of nucleic acids (DNA and RNA). They consist of a sugar molecule, a phosphate group, and a nitrogenous base. The size of a nucleotide is larger than an atom but still microscopic relative to other items.

6. Glucose molecule: A glucose molecule is a simple sugar that is often used as an energy source in living organisms. It consists of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. Glucose molecules are larger than nucleotides.

7. Fungal cell: A fungal cell refers to a single cell that makes up a fungus. Fungal cells are significantly larger than molecules and atoms as they are microscopic organisms.

8. Mitochondria: Mitochondria are membrane-bound organelles found in most eukaryotic cells. Although they are still extremely small at the cellular level, they are larger than individual fungal cells.

9. Heart: The heart is a complex organ found in many animals, including humans. It is considerably larger than cells, organelles, molecules, atoms, and nucleotides.

10. Tundra: The tundra is an ecological biome characterized by low temperatures and short growing seasons. It encompasses vast areas of land, making it much larger than any of the previously mentioned items.

Therefore, the ranking of items from smallest to largest is:

Electron < Hydrogen atom < Sodium atom < Carbon atom < Nucleotide < Glucose molecule < Fungal cell < Mitochondria < Heart < Tundra
