Explain how health care professionals treat unregulated (or abnormal) cellular growth in the body

Alexeev081 [22]

New cells are typically produced during cell division. Cell division is a complex process that is regulated and checked at many points. Due to varying factors, the cell regulation mechanism may become non functional and this usually result in abnormal cell growth and division.

An abnormal cell growth may be cancerous or non cancerous. The best thing to do when one notices an abnormal growth in his body is to go and see the doctor. The doctors will administer appropriate test in order to determine the type of tumor that is present. If the tumor is non cancerous it will be removed by minor surgery. In case the tumor is cancerous, appropriate treatments will depending on the part of the body where it is found, the stage of growth and nature of the cancerous cells.

Answer:

<em>1. The characteristic thing about </em><em>adult frog breathing</em><em> is that </em><em>drawing in air by lowering their mouth floor</em><em> (option d).</em>

<em>2. The substance released by the </em><em>lung secretory cells </em><em>is the </em><em>surfactant </em><em>(option c).</em>

<em>3. The main divisions of the </em><em>peripheral nervous system</em><em> are the </em><em>somatic and autonomic systems</em><em>.</em>

Explanation:

<h3>1. Breathing of the adult frog</h3>

The adult frog - while out of the water - uses a nasal breath, propelling air into its throat and oral cavity. The air content in the frog's mouth causes the internal pressure of the cavity to increase, and the floor of the mouth is modified to allow the passage of air to the lungs.

Under water, the frog's breath is cutaneous, that is, through its skin.

Adult frogs do not have gills or respiratory muscles.

<h3 /><h3>2. Pulmonary surfactant </h3>

Pulmonary surfactant is a substance produced and secreted by the pulmonary epithelium, specifically by type II pneumonocytes. The function of the surfactant is to keep the pulmonary alveoli open to allow gas exchange.

The surfactant is a substance of a lipidic and proteic nature that helps reduce the surface tension of the water, which in the socket prevents closure when the air is exhaled.

Another function is to prevent the germs - viruses and bacteria - present in the air from passing from the alveolus to the bloodstream.

<h3 /><h3>3. Divisions of the peripheral nervous system</h3>

The peripheral nervous system is dependent on the central nervous system and is made up of all the nerves that go to each of the tissues and organs of the body. It is divided into somatic and autonomic nervous systems.

<u>Somatic nervous system</u> is composed of nerves that drive nerve impulses to skeletal muscles, being predominantly voluntary. The involuntary response in this system is due to the existence of reflex arcs, whose center of integration is the spinal cord.
<u>Autonomic nervous system</u> is responsible for the innervation of coughs the internal organs, allowing their function under the coordination of the central nervous system. It is an involuntary system and is subdivided into sympathetic and parasympathetic systems.

The integration of both systems, somatic and autonomic, allows a body to perform all its functions, including the function of relationship, alertness and maintenance of organic homeostasis.

________ is a relatively indigestible strengthening polymer that accounts for more than a quarter of the dry mass of wood.

xxMikexx [17]

Lignin

It is a complex organic polymer that form an important structural materials in the support system of vascular plants and can also be found in some algae. This is an important molecule in the structural composition of cell wall, such as in wood and bark. This also allow woods and barks to have strong, rigid which allows them to no break easily. Lignin can also be found inserted in the cell wall of this plants.
