Unfortunately, I cannot draw diagrams directly in this format. However, I can describe the process for drawing the thyroid gland diagram:
Step 1: Drawing the thyroid gland.
Draw a butterfly-shaped structure, which is the thyroid gland. It consists of two lobes connected by a narrow region called the isthmus.
Step 2: Labeling the components.
- Label the outer layer as "Thyroid Follicle."
- The inner region of the follicle is filled with colloid, where thyroid hormones are stored.
- Label the outer cells of the follicle as "Follicular Cells."
- Blood capillaries surround the follicles for hormone transport.
