- There are two types of cells that make up the xylem: tracheids and vessel elements. Both of these cell types are dead when they are used in the xylem. Using dead cells, which don’t have organelles filling them up, allows more capacity for transporting water.Tracheids are long, narrow cells whose ends overlap.ylem and phloem make up the vascular tissue. The vascular tissue is arranged in bundles, and is easy to see in a cross-section of a stem: Another important tissue is the dermal tissue, which is the outer protective layer. Plants don’t have skin exactly, but they do have an epidermis.

What Is the Function of Vascular Tissue? Tracheids and vessel members are referred to as tracheary elements. Phloem vascular tissue contains parenchyma and has two types of cells that assist in the transport of food: sieve-tube members and sieve cells. Sieve-tube members are more specialized and are present in advanced flowering seed plants. Learn more about Human Anatomy

Nose, Pharynx, Larynx, Trachea, Bronchi, Bronchioles (Conduction Zone) The larynx also has the vocal cords that make sound for speech. After air passes through the larynx, they enter the trachea. The trachea (windpipe) is about 4 inches long (12 cm) and is kept open by tiny rings of stiff cartilage. The last ring of cartilage is called the carina and is covered by sensitive tissue.

HISTOLOGICAL FEATURES OF TONSIL Waldeyer's Ring of Lymphoid Tissue. The lymphoid tissue that surrounds the opening into the respiratory and digestive systems forms a ring. The lateral part of the ring is formed by the palatine tonsils and tubal tonsils (lymphoid tissue around the opening of the auditory tube in the lateral wall of the nasopharynx).he tonsils constitute a lymphoid tissue that lies beneath, and in contact with, the epithelium of the initial portion of the digestive tract. Depending on their location, tonsils in the mouth and pharynx are called palatine, pharyngeal, or lingual.

Respiratory | Trachea, bronchioles and bronchi The supporting lamina propria underneath the epithelium contains elastin, that plays a role in the elastic recoil of the trachea during inspiration and expiration, together with blood vessels that warm the air. The sub-mucosa contains glands which are mixed sero-mucous glands.he epithelium is either columnar or cuboidal. The final branches of the bronchioles are called terminal bronchioles. These have a layer smooth muscle surrounding their lumens. Stimulation of the vagus nerve (parasympathetic) causes the smooth muscle to contract, and reduce the diameter of the terminal bronchioles.

Overview of the Respiratory System The airways resemble an upside-down tree, which is why this part of the respiratory system is often called the bronchial tree. Large airways are held open by semiflexible, fibrous connective tissue called cartilage. Smaller airways are supported by the lung tissue that surrounds and is attached to them.The walls of the smaller airways have a thin, circular layer of smooth muscle. The airway muscle can dilate or constrict, thus changing airway size.At the end of each bronchiole are thousands of small air sacs (alveoli).he airways resemble an upside-down tree, which is why this part of the respiratory system is often called the bronchial tree. Large airways are held open by semiflexible, fibrous connective tissue called cartilage. Smaller airways are supported by the lung tissue that surrounds and is attached to them.

- The LARYNX is an apparatus made up of cartilage, ligaments, muscles, and mucous membrane, which guards the entrance to the lower respiratory passages (trachea, bronchi, and lungs) and houses the vocal cords.Figure 4 shows the major cartilaginous and ligamentous structures which make up the larynx.he PHARYNX is a fibromuscular tube which extends from the base of the skull to the lower border of the cricoid cartilage (at which point it becomes the esophagus). Portions of the pharynx lie posterior to the nasal cavity (nasal pharynx), oral cavity (oral pharynx) and larynx (laryngeal pharynx).

Trachea (Windpipe) In the thorax, the trachea ends where it splits into the left and right bronchi, which continue onward toward the lungs. Viewed in cross section, the trachea is about one inch (2.6 cm) in diameter. It has a thin, membranous wall with C-shaped rings of cartilage embedded into it.Between sixteen and twenty cartilage rings are stacked along the length of the trachea, with narrow membranous regions spaced between the cartilage rings.he open ends of the cartilage rings face the posterior of the trachea near the esophagus. Four layers of tissues make up the walls of the trachea: 1  The mucosa is the innermost layer and consists of ciliated pseudostratified columnar epithelium with many goblet cells.

Contents: Bone vs Cartilage Types of cartilage include hyaline cartilage, fibrocartilage, and elastic cartilage. Hyaline cartilage is the most abundant of the three types. It is found mainly in the bronchial tubes, larynx, nose, and trachea, in the end of long bones, and in the embryonic skeleton. bone is hard tissue that forms the skeletal structure of the body. Cartilage, by comparison, is not as hard and rigid as bone, and is present in areas of the body like the ear, nose, and joints.

Difference Between Vessel Elements and Tracheids Summary: Vessels have perforations at the end plates while tracheids do not have end plates. Tracheids are derived from single individual cells while vessels are derived from a pile of cells. Tracheids are present in all vascular plants whereas vessels are confined to angiosperms.Tracheids are thin whereas vessel elements are wide. Tracheids have a much higher surface-to-volume ratio as compared to vessel elements.Vessels are broader than tracheids with which they are associated.Morphology of the perforation plate is different from that in tracheids.racheids are thin whereas vessel elements are wide. Tracheids have a much higher surface-to-volume ratio as compared to vessel elements. Vessels are broader than tracheids with which they are associated.

What is Hyaline Cartilage? Hyaline cartilage is a type of body tissue, also called gristle. It is shiny, slippery, firm, translucent, and bluish-gray in color. It is simple in structure, with no nerves or blood vessels.It has high elasticity and helps cushion and protect bones.yaline cartilage appears on the ends of bones where they form joints. Hyaline cartilage connects the ribs to the sternum. Hyaline cartilage can be found in the trachea.

Gross Anatomy The larynx is composed of 3 large, unpaired cartilages (cricoid, thyroid, epiglottis); 3 pairs of smaller cartilages (arytenoids, corniculate, cuneiform); and a number of intrinsic muscles (see the image and video below). The hyoid bone, while technically not part of the larynx, provides muscular attachments from above that aid in laryngeal motion. [1, 2, 3, 4, 5] Larynx anatomy.
