The structure being described is the tricuspid valve.The right atrium is one of the two atria of the heart which function by receiving blood entering the heart, it is located to the right of the left atrium and superior to the much larger and more muscular right ventricle. Between the right atrium and right ventricle is a one way valve known as the tricuspid valve.

This simple concept describes the process by which cells exchange toxic gases for life-sustaining gases. It also describes how nerve cells are able to send electrical signals to each other cells. Diffusion tells embryonic cells where to crawl and when they have arrived. Diffusion also makes it possible to reduce the loss of body heat to the surrounding environment.
An adrenal gland can develop an uncommon, often benign (noncancerous) tumor called a pheochromocytoma.
- A (pseudo)hypoxic signature is seen in many solid tumors, such as paraganglioma (PGL) and pheochromocytoma (PHEO). It has been demonstrated that (pseudo)hypoxia encourages the development of tumors and therapeutic resistance.
- Hypoxia-inducible factors (HIFs) are the main mediators of the transcriptional hypoxic response.
- The transcription of hypoxia-responsive genes, which are involved in cancer, is induced by high levels of HIFs. Catecholamine-producing tumors called PHEOs and PGLs develop from sympathetically or parasympathetically generated chromaffin tissue.
- HIF signaling appears to be crucial for the growth and development of PHEOs and PGLs, which may point to novel therapeutic strategies for the management of these malignancies.
