Illustration of follicles in the thyroid gland

Thyroid gland. Illustration of the microscopic cell structure of the human thyroid gland, with an outline of the whole gland superimposed. The white outline (at centre) represents the shape of the thyroid gland, located in the neck. Its cellular structure (background) consists of round follicles which produce thyroid hormone. Cut through, the follicles are composed of cuboidal epithelial cells (purple) which secrete hormones (light blue) into a central storage chamber. Each follicle is surrounded by a network of blood capillaries (red) which transport secreted thyroid hormone in the blood to the rest of the body. Nerves are yellow. Thyroid hormones control metabolism and growth

Artwork of enlarged bladder in urinary retention

Urine retention. Illustration of an enlarged male bladder caused by acute retention of urine. At upper centre is the enlarged bladder (red). Two ureter tubes (white, upper left and right) pass urine from the kidneys to the bladder. At lower centre is the prostate gland (pink); a pair of seminal vesicles (white) are above the prostate; tubes of the vas deferens are seen above the seminal vesicles. Urine retention is the inability to empty the bladder or difficulty in doing so. It may be due to bladder stones, phimosis (tight foreskin), or prostate tumour. It may also occur in pregnancy. A catheter may be used to drain the bladder, before treating the underlying condition
