what will happen if one of the levels in the biological organization will not perform its function properly?​
Sedaia [141]

Answer:

It would affect the functionality of the other levels including the organism

Explanation:

The level of biological organization is a hierarchical step consisting of how a multicellular organism forms. According to this level of organization, CELLS are the simplest unit of life and the collection of cells with a similar function is termed TISSUE. Tissues form ORGANS, organs form ORGAN SYSTEMS and finally, a collection of all the systems in the body forms the ORGANISM.

Based on this, one would observe that each level is related to the next in such a way that one forms from the other. Hence, if one of the levels in the biological organization will not perform its function properly, the other levels will be affected. For example, if the kidney cells do not perform it's function, it would affect the functionality of the kidney tissues, kidney organ, the excretory system, and the organism at large.

Describe pulmonary circulation pathway using the following terms: deoxygenated blood, left atrium, lungs, oxygenated blood, pulm
ehidna [41]
Definition:
                  "The type of circulation pathway in which venous blood is passed
                   <span>from the right atrium of the heart through the right ventricle  and 
</span>                   pulmonary<span> arteries to the lungs where it is oxygenated and its                             return via the </span>pulmonary<span> veins to enter the left auricle and                                                      participate in the systemic </span>circulation"<span>.

Explanation:
                     There are two circulatory path in cardiovascular system namely pulmonary circulation and systemic circulation. Pulmonary circulation path allows for blood circulation through lungs for oxygenation while systemic circulation allows for transport of oxygenated blood to all parts of the body.

Pulmonary Circulation Pathway:
                                                      Pulmonary circulation pathway consist of:

1. Superior and inferior vena cava:
                                                       De-oxygenated blood from lower parts of the body enter to right atrium through inferior vena cava. Similary, deoxygenated blood from upper parts of the body enter to right atrium through superior vena cava.

2. Right atrium and right ventricle:
                                                          From right atrium the blood passes to right ventricle through tricuspid valve. 

</span><span> 3. Pulmonary artery:
                                Afterwards, the blood enters the pulmonary artery via the pulmonary valve. The pulmonary artery divides into two arteries with one artery entering the right lung and the other artery entering the left lung. When the blood reaches the lungs through the left and right pulmonary arteries, it moves over alveoli via the capillary beds. </span><span>

</span><span>4. Left atrium and left ventricle:
                                                 After the blood gets oxygenated, it moves back to the heart and this time moves into the left atrium, completing the pulmonary circulation path.</span><span>
