Describe how lymph nodes and organs help the immune system fight pathogens.
I am Lyosha [343]

The defense system of the human body is made up of entire organs and vessel systems like the lymph vessels, but also of individual cells and proteins. The inner and outer surfaces of the body are the first barriers against pathogens (germs). These surfaces include the skin and all mucous membranes, which form a kind of mechanical protective wall.

Several things support this protective wall:

<span><span>- The body’s own antibacterial substances can disable different pathogens from the environment at an early stage. A certain enzyme found in saliva, the airways and tear fluid destroys the cell walls of bacteria.
</span><span>
- Many pathogens that are breathed in get stuck to mucus in the bronchi and are then moved out of the airways by hair-like structures called cilia.
</span><span>
- Most pathogens that enter the body together with food are usually stopped by stomach acid.
</span><span>
- Normal flora, harmless bacteria that reside on the skin and many mucous membranes in the body, also help to protect the body.</span></span>

The cough and sneeze reflex can also help to remove pathogens.


Hope this helps (:

In complete sentences, explain the path which blood travels in the heart, be sure to include the names of the chambers and major
ehidna [41]

First, deoxygenated blood flows into the right atrium of the heart from the inferior and superior vena cava.

Blood then flows through the bicuspid valve and into the right ventricle.

The blood then flows through the pulmonary valve and into the pulmonary artery. Arteries carry blood away from the heart while veins return blood to the heart. The pulmonary artery is on of the only arteries that carries deoxygenated blood.

Blood will then pass through the lungs and will be oxygenated.

After being oxygenated, the blood enters the pulmonary veins. The pulmonary veins are some of the only veins that carry oxygenated blood.

Blood enters back into the heart through the left atrium.

Then, blood flows into the left ventricle through the mitral valve.

Finally, blood is pumped through the aortic valve, into the aorta, and is distributed throughout the body.

What is the source of carbon for terrestrial plants? terrestrial plants acquire carbon from the .
castortr0y [4]

During this process, plants cleave the carbon from the two oxygen molecules and terminate the oxygen back into the surrounding circumstances.

<h3>What is terrestrial plants?</h3>
  • In terrestrial communities, plants transform atmospheric carbon dioxide into carbon-based combinations through photosynthesis (see above The photosynthetic operation). During this process, plants cleave the carbon from the two oxygen molecules and terminate the oxygen back into the surrounding circumstances.
  • Many terrestrial manufacturers are not even helophytes but rainforest species that tolerate occasional inundation. Examples of these types of plants contain Syngonium, Philodendron, Adiantum, Aglaodorum, Aglaonema, Cordyline, Ophiopogon, and Physostegia.
  • Terrestrial manufacturers are defined as any manufacturer that grows on, in, or from the land. By contrast, aquatic plants are manufacturers that thrive when their roots are submerged in moisture.
