Heart attacks happen suddenly when one of the arteries leading to the heart becomes blocked and cuts off the blood flow. Without oxygen, the heart muscles start to die.
Heart failure, on the other hand, usually develops gradually. The heart muscle becomes weaker and has trouble pumping blood to nourish the cells in your body. This is a chronic condition that gradually gets worse. But medications can help you live longer and better with it
Answer:
The first one, the third one, and the last one.
Explanation:
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.
