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:
d. the patient's injuries occurred only after his discharge.
Explanation:
The burden of proof in a lawsuit alleging professional negligence requires that, the patient's injuries occurred only after his discharge.
This means that, the proffesionals had no wrong doing because the patient sustained injuries after being discharged from the hospital.
Answer: It can cause higher mortality rates, but also reduce stroke.
Explanation:
Studies show that atenolol can reduce stroke risk, but not mortality rates, heart attack rates, and cardiovascular events in the elderly.
Answer:
D) shock
Explanation:
Hypoperfusion is caused by insufficient oxygen and nutrient delivery to body tissues. It is also called as shock because if not treated on time it can lead to failure of organ tissue system. There can be many reasons for hypoperfusion or shock but in the end all of them lead to decreased cardiac output. Sometimes shock can occur even when cardiac output is normal. This happens because the body requirement for oxygen and nutrients is so high that normal cardiac output is not sufficient for delivering them. This situation can occur during fever, infection and extreme pain.
