true or false? to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thor
faltersainse [42]

The thorax is a very vital and important organ in the human body.

  • It is a structure that serves as a<u> </u><u>protective covering</u> for organs in the body such as<u> the lungs, the heart, some vital blood vessels</u> e.t.c

It is<u> false</u> that to <em>make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.</em>

  • When a person breathes in,  <u>the chest cavity expands (the volume increases) and the pressure in the thorax decreases.</u>

  • When a person breathes out, <u>the chest cavity decreases in size, and the pressure in the thorax increases. </u>

  • Therefore, we can see that the <u>process of breathing in humans</u>, follows the <u>principle of Boyle's Law.</u>

  • Boyle's law states that as the<u> volume increases there is a decrease in pressure</u> and <u>as the volume decrease there is an increase in pressure. </u>

Therefore, It is <u>false</u> that to <em>make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.</em>

The different types of the Connective tissue are the Cartilage, Bone Tissue, White Adipose Tissue, Fascia, Fibrocartilage, Hyaline Cartilage, Elastic Cartilage, Costal Cartilage, Brown Adipose Tissue, and Adventitia....


Cartilage- Found in the Joints between bones, the elbow, your knees and ankles, the vertebrae, and on the end of ribs

Bone Tissue- Bone Tissue is found in small blood vessels, epithelium, and the nerves.

White Adipose Tissue- Is located beneath the skin, around internal organs, in bone marrow, and the breast tissue

Fascia-<span>This is the dense fibrous connective tissue that interpenetrates and surrounds the muscles, bones, nerves and blood vessels of the </span>body<span>. This suspends the organs within their cavities and wraps them in layers of connective tissue membranes.

Fibrocartilage- Found in the public </span>symphysis, the anulus fibrosis of intervertebral discs.

Hyaline Cartilage- Found in the Bronchi, bronchial tubes, costal cartilages, larynx, nose, and the trachea.

Elastic Cartilage- Found in the Epiglottis, and the Pinnae.

Costal Cartilage- Found at the anterior ends of the ribs.

Brown Adipose Tissue- Found in Neonates, brown fat<span> makes up about 5% of the body mass and is </span>located<span> on the back, along the upper half of the spine and toward the shoulders.

Adventitia- Is found in the Connective System and in the nerves.....


I hope this helps with this question you asked!!! It states the different types of the connective tissue and where they can be found!!!! Have a great </span>day!!!
