I'm Gary Buckholz, Palliative Medicine Fellowship Director at The Institute for Palliative Medicine at San Diego Hospice. One of the most important things I can do is to decrease the symptom burden for patients who are suffering, and one of the most common symptoms I treat is shortness of breath, or dyspnea.
Organelles are specialized membrane-enclosed structures in the cytoplasm of eukaryotic cells. The nucleus, which contains DNA in the form of chromosomes, is the most characteristic eukaryotic organelle.The nuclear envelope is connected to a system of membranes in the; cytoplasm called the endoplasmic reticulum (ER).he nucleus, which contains DNA in the form of chromosomes, is the most characteristic eukaryotic organelle.

The defining membrane-bound structure that differentiates eukaryotic cells from prokaryotic cells is the cell nucleus, within which the genetic material and many other cell bodies are contained. The presence of a nucleus gives eukaryotes their name that derives from the Greek (eu, good) and (karyon, kernel).Most eukaryotic cells also contain other membrane-bound organelles such as mitochondria, chloroplasts and the Golgi apparatus.ukaryota is one of the three domains of life contianing organisms whose cells contain complex structures enclosed within complex membranes call endomembranes. These organisms are called Eukaryotes and are either singular-or multiple-celled.
