Nastasia [14]

Answer:

Input is oxygen and output is carbondioxide or the movement.

Explanation:

These two systems i. e. scuba diver and scuba gear interacting with each other by giving oxygen to the individual and remove carbondioxide gas from the diver. The input of this system is oxygen that is required by the diver while the output is the carbondioxide gas produced by the diver or the movement of the diver. This scuba gear is responsible for the removal of carbondioxide gas from the system. This scuba gear enable us to stay in deep water for 60 minutes.

The viral pathogen that causes cold sores can remain inactive in the body for a long time between disease outbreaks. How is this

Serhud [2]

This disease is classified as a latent disease.

<h3>Classification of diseases</h3>

Latent disease is a classification of disease whereby the infectious agent remains inert in the body of its host between episodes of recurrent diseases.

Examples of viral pathogens that causes latent diseases include:

<em>Herpes simplex, </em>

<em>Varicella zoster, </em>

<em>Epstein-Barr</em>,

<em>Human cytomegalovirus, </em>

Adenovirus, and Kaposi's sarcoma.

The infection caused by the listed viral pathogens exhibit a latent disease phase whereby there is no noticeable symptoms of infection.

Failure in a particular structure of the heart tends to cause a backup of blood in the lungs, known as pulmonary congestive hear

xeze [42]

Answer:

Left ventricle.

Explanation:

Human heart is divided into four chambers - two auricles and two ventricles. Heart acts as the pumping organ and carries both oxygenated and deoxygenated blood in the right and left ventricles.

The failure of functioning of any chamber of heart may cause a particular disease in the individuals. The pulmonary congestive heart failure occurs due to the failure of the left ventricles of the heart. The left ventricle carries blood from heart to the body tissues, its failure leads to the backup of blood in the lungs.

Thus, the answer is left ventricle.
