Cryptosporidiosis, a diarrheal disease caused by Cryptosporidium parvum protozoan. 3D illustration showing release of parasite sporozoites from oocyst inside small intestine

Human Large Intestine,Appendix in human body

Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.

Neuroendocrine carcinoma well differentiated (carcinoid) rectum with immunostain synaptophysin

The detrusor muscle remains relaxed to allow the bladder to store urine, and contracts during urination to release urine 3d illustration

Photomicrograph of midge fly, Chironomidae family, eggs hatching. Eggs are encased in a gelatinous material that attracts debris. Live specimen. Larva about 0.5 mm long. Wet mount, 10X objective, transmitted brightfield illumination.

Gastric mucosa stained with the Masson trichrome stain showing: surface epithelium, gastric pits with foveolar cells, fundic glands and muscularis mucosae.

Cardiac amyloidosis is a condition where faulty proteins build up in your heart. You can inherit this condition, or it can develop on its own (usually later in life). As faulty proteins accumulate, your heart struggles to pump, ultimately leading to heart failure and death.

Photomicrograph of the ciliate Blepharisma americanum in various stages of development. Typical faint pink color. Each individual is only one cell. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.

The esophagus is the hollow, muscular tube that passes food and liquid from your throat to your stomach 3d illustration

Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens. Depth of focus is extremely shallow (just a few microns). Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Fatty liver disease (steatosis) is a common condition caused by having too much fat build up in your liver. A healthy liver contains a small amount of fat. It becomes a problem when fat reaches 5% to 10% of your liver's weight.

Frogs are a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura

Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
