Human Anatomy Illustrations

Detailed illustrations of human anatomy, showcasing systems like the blood-brain barrier and reproductive structures, highlighted in vibrant and soft color gradients.

Female reproductive system, illustration.

Representation of the blood-brain barrier between the bloodstream and the central nervous system. It serves to regulate the environment (homeostasis) in the brain, separating it from the blood. Although the endothelial cells that line the capillaries are the essential components of this barrier, the astrocytes surrounding the blood capillaries in the brain (in purple) also constitute the blood-brain barrier.

Composition of blood in a blood capillary. This illustration represents all the elements that make up blood. First of all, the elements of blood are bathed in plasma. The plasma is shown in transparency in yellow. There are erythrocytes, or red blood cells or red blood cells, and platelets, antibodies and white blood cells, actors in the immune reaction. The red blood cells represented in red are the element of the blood in greater number. While the other elements are less numerous. First of all the platelets are the smallest elements (in blue) scattered around the vessel. Antibodies are shown in yellow in the shape of a Y. Then the other elements in purple are white blood cells. A T lymphocyte is located in the center of the vessel in purple and green. While the large purple cell in the foreground, as well as the one that passes through the vessel wall are leukocytes. The first is a monocyte, the second that passes through the wall is a neutrophil. Finally, outside the vessel is a mac

For the following reasons, adult stem cells may eventually prove to be better for cell therapy than embryonic stem cells: their greater availability in adult tissue, the absence of immune-response rejection, their decreased disposition for tumors. Removed from the patient, stem cells can be cultured and multiplied to attain a quantity that is sufficient to treat sickness or injuries. Here, culture of muscle stem cells to be transplanted to the cardiac muscle.

All uses except for pharmaceutical laboratories in Belgium - Invasive bladder cancer, stage II, muscle damage. This illustration shows a woman's bladder with a stage II invasive cancerous tumor at the top right of the bladder wall. From there starts a zoom at the level of the bladder wall with all its structures which shows the appearance of this stage II tumor, represented in white. From bottom to top we have the bladder cavity, the epithelium (bluish gray cells), the connective tissue, the muscle consisting of three layers and finally the tissue that surrounds the bladder, here the parietal peritoneum. At this stage of the cancer, the tumor invades the bladder muscle. This stage II is divided into two stages. In the T2a stage, the tumor reaches the lower half of the bladder muscle. While in the T2b stage, the tumor reaches the outer half of the bladder muscle. So in this drawing, we have a T2b stage tumor. - - Restriction : All uses except for pharmaceutical laboratories in Belgium f

Representation of the transmission of the pain at the level of the spinal cord. The presynaptic neuron releases the neurotransmitters of the pain via synaptic vesicles. These neurotransmitters are released in the synaptic cleft and fixes on the receptors of the synapse of the postsynaptic neuron. The nerve impulse is then created and the information of the pain is transported to the brain. The neuron on the right is the neuron of the inhibition of the pain located at the level of the spinal cord.

Tissue blood capillaries connect the arterioles to the venules. These are the smallest blood vessels in the body. Arterioles are connected to arteries of more average caliber. And they represent the arterial circulation from the heart to the tissues (in red). So they provide the cells of the tissues with the nutrients and oxygen necessary for their functioning. The venules represent the venous circulation, from the tissues to the heart (in blue). And they are connected to medium caliber veins. So they recover the waste and the CO2 for their disposal. Thus, these tissue capillaries are organized in tree networks. They are also called capillary beds. And they come together and intertwine in the tissues and therefore interact closely with them. It is also at their level that blood pressure is lowest.

Heart disease, illustration

Anatomy and physiology of the renal system, kidney, glomerulus and renal physiology. This illustration represents the anatomy of the urinary system and more particularly of the kidney and the glomerulus. From left to right, the urinary system is represented in a woman's silhouette with the kidneys, adrenal glands, ureters, bladder. In addition, we distinguish the vascularization of the kidney with the renal veins and arteries from the inferior vena cava and the abdominal aorta. The physiology of the kidney is illustrated in the center with the organ in section. The kidney regulates the amount of water in the body by injecting water and minerals back into the bloodstream (red arrows). They produce hormones, erythropoietin (pink pastilles) for the production of red blood cells and renin (green pastilles) for the regulation of blood pressure. Finally, it eliminates waste from the body by filtering the blood at the level of the glomerulus (zoom). The organic residues are evacuated in the f
