A tissue that has a fluid matrix is
Extracellular matrix and interstitial fluid – what is the
The most common form of connective tissue in vertebrates is loose connective tissue. It binds epithelial tissue to other underlying tissues and keeps organs in place. It forms telae that attach mucous and serous membranes to the muscular layer, such as the tela submucosa and tela subserosa. The blood vessels and nerves are still surrounded by it. Fibroblasts, which are irregular branching cells that secrete strong fibrous proteins and proteoglycans as an extracellular matrix, are widely distributed in this tissue. A gelatinous material predominantly made up of collagenous and elastic fibers separates the cells of this type of tissue by a significant distance.
The mucous connective tissue of the fetus, areolar connective tissue, reticular connective tissue, and adipose tissue are all considered “loose connective tissue” in most cases.
It’s present in almost every part of the body’s tissue parts. It encircles blood vessels and nerves, penetrating into the narrow spaces between muscles, tendons, and other tissues with them. It’s even possible that it’s present in the mediastinal extremities. Almost every epithelium is supported by a layer of areolar tissue, which contains blood vessels that provide nutrients, waste removal, and a ready supply of infection-fighting leukocytes when required. Since there is so much open, fluid-filled space in areolar tissue, leukocytes can travel around freely and quickly locate and kill pathogens.

For structural and metabolic purposes, connective tissue integrates, protects, binds, and separates organs and tissues, forming a structure to sustain body tissues and organs. Cells in connective tissue are few and dispersed, as opposed to epithelial tissue, where they are close together. The majority of connective tissues have blood vessels (except cartilage). The extracellular matrix refers to the extracellular spaces (space outside of cells) in connective tissue.
As a result, connective tissue is made up of cells and extracellular matrix. Glycosaminoglycans and proteoglycans make up the extracellular matrix. The properties of connective tissue are determined by differences in the extracellular matrix composition.
Bone, blood, cartilage + other connective tissues!
This is a dense irregular connective tissue example. The dermis is the layer of skin that lies under the epidermis. Collagen fibers and fibroblasts are present. A tiny capillary can also be seen at the top of the image (not labeled) – can you spot it?
A thick woven network of collagenous (and some elastic) fibres in a viscous matrix makes up this type of tissue. It can be present in joint capsules, the connective tissue that covers muscles (muscle fascia), and the skin’s dermis. It has a high impact resistance.
Collagen fibers are closely packed and arranged in parallel in this type of tissue. Ligaments (which bind bone to bone at joints) and tendons contain this form of tissue (connections between bones or cartilage and muscle). These are highly resistant to axially loaded tension forces while still allowing for some stretch.

Q) What Is the Role of the Fluid Matrix in Blood Tissues?
Fluid tissue – tissues (cbse grade 09 biology)
Answer: Blood is a connective tissue with no fibers and a fluid matrix called plasma. The predominant cell group, erythrocytes (red blood cells or RBCs), are involved in the transport of oxygen and carbon dioxide. Various leukocytes (white blood cells or WBCs) involved in the immune response are also present. Plasma is the fluid component of entire blood, also known as the matrix. Blood is known as a fluid connective tissue because of the living cells floating in the plasma (not a fluid). It is the body’s only fluid tissue.
