superior view of heart showing opening of aorta, superior vena cava, pulmonary trunk with related valve
Diatoms, algae under microscopic view, phytoplankton, fossils, silica, golden yellow algae
In vitro bacterial culture
Results from a lung/pulmonary function test (PFT). Shows spirometry graphs and measurements. Results are  within normal limits. PFTs are used to diagnose respiratory problems.
Heart Color Ultrasound Medical Examination Image
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.
Fungal Ear Infection, Need to Use Antifungal Ear Drops to Treat Otomycosis.
Solar radiation analysis of a public building. Multipurpose common public space analysis with parametric louvers to control sun exposure and radiation.
plant rape flower cross section under light mircoscope with white background
grey book isolated on white, blue frame for title on the spine
Abstract marble texture background stock photo, suitable for design.
Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.
Freshwater aquatic zooplankton and algae under microscope view
Transmission electron microscope micrographs  showing the aspect of muscle fiber sarcomere components in longitudinal (below) and transverse (above) sections at the Z-line, I and A bands and H zone
Intricate bubble texture macro in bright colors for abstract background. Liquid bubbles lit from below with colors injected into the liquid as a design or art abstract.
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
The plant roots under the microscope
Paps smear analysis: Superficial squamous cell, metaplastic squamous cell, koilocytes cell. HPV related change
plant Zea Stem C.S. under light mircoscope with white background
Photomicrograph of Euglena species. Fresh water, California. Live specimen. Wet mount, 40X objective, transmitted bright field illumination.
Diatoms, algae under microscopic view, phytoplankton, fossils, silica, golden yellow algae
The Microscopic World. Tap water.
Ultrasound image of a breast
Focused enlarge microscopic view of zoo plankton
Rock texture background High resolution or design art work.
Close up Plant epidermis with stomata or Leaf Epidermis (Stomata) under microscope.
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.
Epithelial Cells in urine sediment.
Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.
