Photosynthesis does not represent diffusion in the human body. Photosynthesis is the process by means of which plants capture sunlight energy and store it as sugar.
Blood cells
Usually a sphere or a group of few spheres.
When the temperature of the human body falls to a level that is potentially fatal, the body's natural reaction is to keep the heart pumping. This means that circulation to other organs besides the heart is stopped. This is why limbs get frostbite in extreme cold.
An item that can represent a vacuole would be a ballon or a plastic bag or even a water bottle because they hold water like a vacuole.
If you're talking about transporting materials into and out of the cells, they would be diffusion, osmosis, neither of which requires the use of energy; and active transport, which does require energy.
There are quite a few examples of diffusion in the human body. They are breathing, sneezing, evaporation, blood diffusion, and homeostasis.
Diffusion occurs in the human body in a variety of ways. Examples of diffusion are through respiration, ion movement and the diffusion of nutrients in the kidney and small intestine.
Simple diffusion occurs in many parts of the human body. Some of these include in the lungs, the skin and in the kidneys.

Diffusion is an important mechanism in the human body. It facilitates the uptake of water and nutrients into the cell, controls metabolic waste excretion and regulates the exchange of oxygen and carbon dioxide in the lungs.
The brain
Diffusion is a body process that does not require energy from respiration.
Blood cells
One example of diffusion in the human body is the movement of oxygen from the lungs into the bloodstream. Oxygen molecules move from an area of high concentration (lungs) to an area of low concentration (bloodstream) through the respiratory membrane. This benefits the body by replenishing oxygen levels in the blood, which is essential for cellular respiration. Another example is the diffusion of glucose from the bloodstream into the cells. Glucose molecules move from an area of high concentration (bloodstream) to an area of low concentration (cells) through the cell membrane. This benefits the body by providing energy for cellular functions and metabolism.

In a cell in the human body diffusion takes place in the cell membrane. The cell membrane allows smaller sized molecules to pass through.
