What are ligaments?
A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.
Why is blood called 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. The fluid portion of whole blood, its matrix, is commonly called plasma.
Where is connective tissue located?
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.
Is blood 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. The fluid portion of whole blood, its matrix, is commonly called plasma.
How does connective tissue protect organs?
Protection is another major function of connective tissue, in the form of fibrous capsules and bones that protect delicate organs. Specialized cells in connective tissue defend the body from microorganisms that enter the body.
Is bone a tissue?
Tissue that gives strength and structure to bones. Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts.
What is the largest connective tissue of the body?
Collagen filaments bind thread-like cells together to form strands, the longest of which can be up to 30 cm long and 0.15 mm thick.
Is muscle a connective tissue?
An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering. Each muscle is surrounded by a connective tissue sheath called the epimysium.
What type of tissue is skin?
Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
What is specialized connective tissue?
Specialised connective tissue includes tendons and ligaments, Bone and Cartilage, haemopoetic tissue, blood and adipose tissue. Bone contains Osteocytes, and osteoblasts (osteo – bone) which secrete the type of extracellular matrix material (ECM) that makes up bone.
Why is blood called a connective tissue class 9?
Answer: Blood is called a connective tissue because it carries with lots many digestive substances ,Oxygen from lungs ,foods from small intestine, and provide it to other tissues and organs of the body. Since, it connects heart, lungs and small intestine with other tissue of the body and works as a medium between them.
What are the 10 types of connective tissues?

- Adipose Tissue (Fig. …
- White Fibrous Tissue (Fig. …
- Yellow Elastic Tissue (Fig. …
- Reticular Tissue (Fig. …
- Blood and Haemopoietic Tissue:
What is a fat cell called?
Adipose (fat) cells are specialized for the storage of energy in the form of triglycerides, but research in the last few decades has shown that fat cells also play a critical role in sensing and responding to changes in systemic energy balance.
What is epithelium?
The term “epithelium” refers to layers of cells that line hollow organs and glands. It is also those cells that make up the outer surface of the body.
What is the blood tissue?
Blood is actually a tissue. It is thick because it is made up of a variety of cells, each having a different job. In fact, blood is about 80% water and 20% solid. Blood is made mostly of plasma, but 3 main types of blood cells circulate with the plasma: Platelets help the blood to clot.
What type of tissue is the bone?
Cartilage and Bone are specialised forms of connective tissue. They are both made up of cells embedded in an extracellular matrix. It is the nature of the matrix that defines the properties of these connective tissues. Cartilage is thin, avascular, flexible and resistant to compressive forces.
Who is organ?
An organ is a self-contained group of tissues that performs a specific function in the body. The heart, liver, and stomach are examples of organs in humans. The word organ comes from the Latin organum, which means “instrument”. … Organs are found in most animals and plants.
What is the columnar epithelium?
The columnar epithelium is composed of epithelial cells that are column-shaped. The cell comprising the columnar epithelium is taller than it is wide. Its height is approximately four times its width. The nucleus in each cell is elongated and often found near the base.
What are joints?
What Are Joints and What Do They Do? Joints are where two bones meet. They make the skeleton flexible — without them, movement would be impossible. Joints allow our bodies to move in many ways.
What are joint bones?
A joint is the part of the body where two or more bones meet to allow movement. Every bone in the body – except for the hyoid bone in the throat – meets up with at least one other bone at a joint. The shape of a joint depends on its function. A joint is also known as an articulation.
What are synovial joints?
A synovial joint, also known as diarthrosis, joins bones or cartilage with a fibrous joint capsule that is continuous with the periosteum of the joined bones, constitutes the outer boundary of a synovial cavity, and surrounds the bones’ articulating surfaces.
Why is the Colour of the blood red?
Human blood is red because hemoglobin, which is carried in the blood and functions to transport oxygen, is iron-rich and red in color. … It’s bright red when the arteries carry it in its oxygen-rich state throughout the body. And it’s still red, but darker now, when it rushes home to the heart through the veins.
What is the function of WBC?
White blood cells are part of the body’s immune system. They help the body fight infection and other diseases. Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).
