Answer:
Arteries carry blood away from the heart; veins carry blood back to the heart.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole: in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The best description for arteries and veins is that arteries carry oxygenated blood away from the heart to other parts of the body such as brain, lungs, tissues, etc; veins carry blood that is low in oxygen content back to the heart.
In the third picture : I would not play with any kind of electrical appliances which could harm me and i would also teach this to my siblings. I would not touch them with wet hands .
I think they are all examples of minerals. They come in vitamin for though.
hope this helps!
Perseverance is a very good habit to cultivate, <em>which</em><em> </em><em>when</em><em> </em><em>developed </em><em>will </em><em>help </em><em>the </em><em>person </em><em>that </em><em>cultivate</em><em> </em><em>to </em><em>be </em><em>able </em><em>to </em><em>try </em><em>again</em><em> </em><em>everytime</em><em> </em><em>something</em><em> </em><em>goes </em><em>against</em><em> </em><em>planned </em><em>strategies</em><em>.</em>
<em>When </em><em>you </em><em>persevere</em><em>, </em><em>you </em><em>will </em><em>keep </em><em>looking </em><em>out </em><em>for </em><em>jobs </em><em>without</em><em> </em><em>relenting</em><em> </em><em>and</em><em> </em><em>giving </em><em>up. </em>
Communicable Diseases are illnesses which are caused by pathogens or microorganisms, e.g virus, and bacteria, that are transmitted from one person or animal to another in different ways. It can spread through contact with body fluids or blood, sexual contact, contaminated food, and water, or through the air.With the advancement of medical science, different ways of controlling communicable diseases have emerged throughout the centuries and have been proven to lessen the mortality rate as time passed.One is the development of Immunization. Immunization; to make one's body immune to a certain disease so it will be easier for the body to combat the pathogens in contact with it. Until now, production of Immunization is still being updated depending upon the diseases that are currently affecting the majority. The development of immunization has given medical science, then and now, a very big impact in controlling diseases. How does it work? Immunization boosts the body's natural immunity whenever microorganisms enter the body. The body identifies these microorganisms as foreign elements, thus releasing certain kinds of cells to help fight off the infection.Hope this helps!!
