Which of the following is a type of connective tissue?
Squamous epithelium
Blood
Neurons
Smooth muscle
Blood
Blood is classified as a fluid connective tissue because it consists of living blood cells suspended in a non-living fluid matrix called plasma. It connects different organs by transporting oxygen, nutrients, hormones, and waste products throughout the body.

Think of blood as a courier service; just as a courier connects a warehouse to a customer by moving packages, blood connects the lungs and digestive system to every cell in the body by moving oxygen and nutrients.

Blood=Plasma+Formed┬аElements

Connective tissues are characterized by having cells embedded in an extracellular matrix. In blood, the matrix is plasma, and the 'fibers' (typically found in other connective tissues) are represented by soluble proteins like fibrinogen that form fibers only during the clotting process, initiated by the reaction cascade: FibrinogenThrombinтАЛFibrin.
Blood is the only liquid connective tissue in the human body.
The extracellular matrix of blood is the plasma, which is approximately 90%тИТ92% water.
Connective tissues are derived from the embryonic mesoderm.
Unlike other tissues, blood cells do not secrete the matrix fibers under normal physiological conditions.
Provides efficient transport system for nutrients and gases.
Essential for immune response and thermal regulation.
Clinical diagnosis through blood tests.
Systemic delivery of oxygen via hemoglobin.
Average blood volume in an adult is about 5тИТ6 liters.
Squamous epithelium is a type of epithelial tissue that forms thin protective linings.
Neurons are the functional units of nervous tissue.
Smooth muscle is a type of muscle tissue responsible for involuntary movements in organs.
B is correct тАФ Blood is categorized as a specialized fluid connective tissue due to its composition of cellular elements suspended in a liquid matrix.
In competitive exams, remember that connective tissue is defined by the presence of a matrix; always look for the 'matrix' element to identify it, even if the tissue is liquid like blood or solid like bone.
