Which statement best describes how the structure of the alveoli allows the lungs to function properly

zlopas [31]

Out of the following given choices;

a. they increase the amount of energy transferred from the lungs to the blood

b. they increase the flexibility of the lungs as they expand during inhalation

c. they increase the volume of the lungs, allowing more oxygen to be inhaled

d. they increase the surface area of the lungs, allowing the efficient gas exchange

The answer is D. Due to their microscopic nature, they are numerous in the lungs and are also circular-shaped so as to increase the surface area for gaseous exchange. Other characteristics of alveoli that increase gas exchange are that they thinned-walled (with only a layer of cells) and moist.

The prefix endo- is Greek for “within.” If the word part plasm refers to the “body” of the cell, what does the prefix endo- tell

allsm [11]

If the prefix endo- is Greek for within, and the "plasm" refers to the body of the cell, you can conclude that: The ER actually helps the attached robosomes make proteins. When these new proteins leave the ER (and they do) they move to another/different organelle.

A hypothetical organ has the following functional requirements: (1) the ability to resist surface abrasion and mechanical stress

alukav5142 [94]

Answer:

The <u>five</u> tissues needed that could make up this hypothetical organ are stratified squamous epithelial tissue, smooth muscle tissue, dense irregular connective tissue, loose connective tissue, and nervous tissue.

Explanation:

<h3 /><h3>Ability to resist surface abrasion and mechanical stresses</h3>

Stratified squamous epithelial tissue

This consists of <em>scale-like cells</em> stacked together in layers that provide a <u>barrier that is resistant to abrasions and wear-and-tear</u>. This is also the most common type of stratified epithelium in the body. The top layer of this tissue has two types: <u>keratinized</u>, lined with dead cells with keratin, and <u>non-keratinized</u>, also with dead cells but without the keratin. In the human body, the skin is composed of stratified squamous epithelium.

<h3>Ability to contract involuntarily when stimulated by cells of the nervous system</h3>

Smooth muscle tissue

Smooth muscle, known for its <em>non-striated appearance,</em> is a kind of <u>involuntary</u> muscle cells that are <u>stimulated by neural signals by the autonomic nervous system, hormones, and local factors</u> such as a wall stretch of a certain organ, inflammation of visceral/parietal organs, etc. In the human body, this is mostly found in the <u>walls of blood vessels and organ systems.</u>

<u />

<h3>Ability to resist tension in many different planes of force</h3>

Dense irregular connective tissue

This is a kind of connective tissue made up of <u>collagen fibers arranged randomly.</u> This creates <u>greater strength and support in all directions</u>. It can also <u>return to its original shape</u> even after stretching.

<h3>One tissue to "glue" all other tissues together</h3>

Loose connective tissue

Also known as areolar tissue, it is loosely made up of collagen, elastin, and reticular fibers, and lots of ground substance. It is arranged in a web-like fashion and serves as the "cement" which fills in spaces between tissues.

<h3>One tissue to stimulate the contracting cells</h3>

Nerve tissue

It is a specialized kind of tissue responsible for communication within the body. It transmits and receives signal impulses throughout the body. The 2 types of nervous tissues are neurons and neuroglia.
