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.

pav-90 [236]

Microorganisms such as bacteria, viruses, yeasts and molds can spoil food and may cause a risk to anyone's health. Microbes cause infectious diseases such as flu and measles. But you do have to remember that less than 1% of bacteria can invade our body (the host) and make us ill. So even if it is 1%, that's still 1% that can harm you.

Some examples of how microorganisms affect humans and how they can enter through your body:

Respiratory tract (mouth and nose): Influenza virus which causes the flu.

Gastrointestinal tract (mouth oral cavity): Vibrio cholerae which causes cholera.

Urogenital tract: Escherichia coli which causes cystitis.

Breaks in the skin surface: Clostridium tetani which causes tetanus.
