There are four classes of connective tissues: BLOOD, BONES, CARTILAGE and CONNECTIVE TISSUE PROPER.
What functions are performed by connective tissue?
The primary functions of connective tissues include:
- Transportation of nutrients and metabolites through direct diffusion between organs and connective tissue proper.
- Immunological defense (fights invading cells via inflammation)
- Structural support.
- Tissue repair (after injury)
Where is the connective tissue found?
Connective tissue is found in between other tissues everywhere in the body, including the nervous system. In the central nervous system, the three outer membranes (the meninges) that envelop the brain and spinal cord are composed of connective tissue.
What is the most common connective tissue disorder?
Rheumatoid Arthritis (RA): Rheumatoid arthritis is one of the most common connective tissue diseases and can be inherited. RA is an autoimmune disease, meaning the immune system attacks its own body. In this systemic disorder, immune cells attack and inflame the membrane around joints.
What are the 7 types of connective tissue?
7 Types of Connective Tissue
- Cartilage. Cartilage is a type of supporting connective tissue. …
- Bone. Bone is another type of supporting connective tissue. …
- Adipose. Adipose is another type of supporting connective tissue that provides cushions and stores excess energy and fat. …
- Blood. …
- Hemapoetic/Lymphatic. …
- Elastic. …
What are the 7 functions of connective tissue?
The major functions of connective tissue include:
- Binding and supporting.
- Storing reserve fuel.
- Transporting substances within the body.
What are the major connective tissue types?
The major types of connective tissue are connective tissue proper, supportive tissue, and fluid tissue. Loose connective tissue proper includes adipose tissue, areolar tissue, and reticular tissue.
Which is not a function of connective tissue?
Absorption of nutrients is not a function of connective tissue.
What are the 10 types of connective tissue?
The following points highlight the ten main varieties of connective tissues of human body. They are: 1. Areolar Tissue 2. Adipose Tissue 3.
- Areolar Tissue: …
- Adipose Tissue (Fig. …
- White Fibrous Tissue (Fig. …
- Yellow Elastic Tissue (Fig. …
- Reticular Tissue (Fig. …
- Blood and Haemopoietic Tissue:
What is the most diverse type of connective tissue?
From fat to tendons, connective tissue proper is the most diverse group in this tissue family.
What is connective tissue example?
Specialized connective tissues include a number of different tissues with specialized cells and unique ground substances. Some of these tissues are solid and strong, while others are fluid and flexible. Examples include adipose, cartilage, bone, blood, and lymph.
What are the functions of connective tissue and give example?
Connective tissues bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage. They occur throughout the body.
What are the six types of connective tissue?
Generally, the types of connective tissues are divided into six main groups:
- Loose ordinary connective tissue.
- Adipose tissue.
- Blood and blood forming tissues.
- Dense ordinary connective tissue.
Is blood An example of connective tissue?
Figure 6. Blood is a connective tissue that has a fluid matrix, called plasma, and no fibers. Erythrocytes (red blood cells), the predominant cell type, are involved in the transport of oxygen and carbon dioxide. Also present are various leukocytes (white blood cells) involved in immune response.
Which one is not connective tissue?
Muscular tissue consists of muscle fibres, it is not a connective tissue.
What are the two main types of fibers in connective tissue?
The three types of connective tissue fibers are:
- Collagen fibers – most are type I collagen (most abundant protein in the body)
- Elastic fibers – contain elastin and fibrillin.
- Reticular fibers – contain type III collagen.
What are the types of connective tissue class 9?
Different types of connective tissues include areolar tissue, adipose tissue (fat), blood, bone, and cartilage.
What organs do connective tissue protect?
Loose Connective Tissue
A large number of capillaries allow rapid storage and mobilization of lipid molecules. Fat contributes mostly to lipid storage, can serve as insulation from cold temperatures and mechanical injuries, and can be found protecting internal organs such as the kidneys and eye.
What is the main function of dense connective tissue?
The main roles of dense CT are to transmit forces over a distance and to connect different organs/muscles. Collagen fibres are disposed along the direction of mechanical loads present in that specific tissue.
How many types of connective tissue are there?
Based on the cells present and the ECM structure, we differ two types of connective tissue: Connective tissue proper; further divided into loose and dense connective tissues. Specialised connective tissue; reticular, blood, bone, cartilage and adipose tissues.
Which connective tissue does not contain collagen?
Loose connective tissue is highly cellular and rich in proteoglycans; it contains fewer collagen fibers.
Why is blood called a connective tissue?
Blood is considered a connective tissue because it has a matrix. The living cell types are red blood cells, also called erythrocytes, and white blood cells, also called leukocytes. … Blood Tissue: Blood is a connective tissue that has a fluid matrix, called plasma, and no fibers.
How long can you live with connective tissue disease?
Since MCTD is comprised of a number of connective tissue disorders, there are many different possible outcomes, depending on the organs affected, the degree of inflammation, and how quickly the disease progresses. With proper treatment, 80% of people survive at least 10 years after diagnosis.
