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

Biology

zlopas [31]3 years ago
8 0

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.

nergy used by the body to perform muscular contractions is called adenosine diphosphate, or ADP.TrueFalse
olga2289 [7]

The answer is false.

Energy used by the body to perform muscular contractions and many other energy-required functions is adenosine triphosphate or ATP.

The most important function of ATP is its ability to store and transport chemical energy within cells. That energy can be used for many chemical processes such as muscle contraction, nerve impulse propagation, chemical synthesis.. When consumed in metabolic processes as an energy source, it becomes converted either to adenosine diphosphate (ADP) or to adenosine monophosphate (AMP) because one or two phosphate groups are released (hydrolysis of high-energy bonds).

Since ATP is a nucleoside triphosphate it can be used for the synthesis of nucleic acids.

Which hip bone forms the superioir part of the pelvic girlde that extends upward from the acetabulum
Mars2501 [29]

The ischium bone forms the superior part of the pelvic girdle.

<h3>What is the structure of the pelvic girdle?</h3>

In the bottom region of the trunk, there is a bony structure known as the pelvic girdle that resembles a ring. It joins the lower limbs to the axial skeleton. There are two types of pelvises: the bigger pelvic and the lesser pelvis.

The pelvis is made up of two paired hipbones that are joined at the pubic symphysis in front and by the sacrum in back. Each hipbone is composed of three bones: the blade-shaped ilium above and to either side, which determines the hips' width; the ischium below, on which the weight is placed when sitting; and the pubis in front. Early in maturity, all three come together at a triangle suture in the acetabulum, the cup-shaped socket that connects to the head of the femur to create the hip joint.
