Answer:
The most correct answer is: It varies in consistency based on the amount of protein fibers and fluid
Explanation:
The extracellular matrix (ECM) is the environment surrounding cells, which is normally composed by fibers (i. e.: collagen, elastin, etc...), soluble proteins and other macromolecules (such as hyaluronic acid) embedded in fluid. The relative concentration and composition of those components conditions, among other things, the physical consistency of the ECM.
- No blood vessel arises from ECM; they derive from specific precursor cells. Additionally, cartilage is an avascular (has no blood vessel) type of connective tissue.
- ECM does provide oxygen and nutrients to diverse tissue, including bone, however bone tissue <em>does</em> have blood vessels.
- Neuronogenesis (generation of new neurons) takes place within the developing nervous system, with neuronal precursor cells being thoroughly surrounded by other cells such as radial glia. Typically, neighboring ECM has a minor or negligible role in this process.

Answer:
El sistema respiratorio humano es una serie de órganos responsables de tomar oxígeno y expulsar dióxido de carbono. Los órganos primarios del sistema respiratorio son los pulmones, que llevan a cabo este intercambio de gases a medida que respiramos, otro órgano que nuestro sistema respiratorio tiene es el diafragma, el diafragma es un músculo esquelético delgado que se encuentra en la base del cofre y separa el abdomen del pecho, se contrae y se aplana cuando inhalas. Esto crea un efecto de vacío que atrae el aire hacia los pulmones cuando exhalas, el diafragma se relaja y el aire sale de los pulmones.
In radiology and nuclear medicine, single - photon emission therapy (PET)/computed tomography (CT) scanning is now a standard practice.
<h3>What distinguishes a CT scan from a PET scan?</h3>
The internal organs and tissues of your body are depicted in great detail by a CT scan. A Pet / ct can be more accurate than some other imaging procedures and can detect aberrant activity. Additionally, it can cause your body to alter sooner. PET-CT scans are used by doctors to reveal more details about the cancer.
<h3>What distinguishes an MRI from a PET scan?</h3>
Radio waves and magnets are both used in magnetic resonance imaging (MRI) studies. Both generate static photos of the body's organs and skeletal system. Using a radioactive tracer, PET scans can demonstrate how an organ is working in real time. CT and MRI scans cannot identify cellular responses in tissues and organs as early as PET scan images can.

Seven out of ten deaths occur as a result of one or more chronic diseases, which are present in 133 million Americans.
What is chronic disease?
- A general definition of a chronic disease is a condition that lasts for a year or longer, necessitates continuous medical care, restricts daily activities, or both.
- The Klickitat County Health Department (KCHD) was one of 33 local health departments in Washington State that received funding and technical support from NACCHO to implement the Action Communities for Health, Innovation, and Environmental Change (ACHIEVE) model in an effort to prevent and lower the prevalence of chronic diseases.
- Together with HPA, KCHD established the Little Klickitat River Trail, three community gardens, and a worksite wellness toolkit in addition to completing all five phases of the ACHIEVE program.
