Question

Connective tissue with a fluid matrix is
(a) Ligament
(b) Tendons
(c) Blood
(d) Cartilage

Answer 1

Hint: Connective tissue is a tissue that connects and supports the other types of tissues in the body. This connective tissue consists of a red-colored pigment called hemoglobin and transport nutrients to the body. Connective tissue proper is divided into loose and dense connective tissues.

Complete answer:
Blood is a type of loose connective tissue. The main constituent of blood is its matrix as plasma, which provides blood the fluid nature and is a complex of a solution containing more than 90 percent water along with other proteins and blood cells. The major plasma protein is serum albumin. The following are the major types of blood cells:
 - Red blood cells (erythrocytes)
 - Platelets (thrombocytes)
 - White blood cells (Leucocytes)
So, the correct answer is, ‘Blood’.

Additional Information:
- Red Blood Cells: These are anucleate, biconcave cells consisting of hemoglobin, that transports oxygen and carbon dioxide in the body via the circulatory system.
- Platelets: These are fragments derived from the megakaryocytes produced in the bone marrow, which help the formation of clots during tissue injury and prevent blood loss.
- White Blood Cells: These are our immune cells that fight against the infections and pathogens trying to make us sick.
- White blood cells are of the following types:
- Monocytes help to engulf and kill the bacteria.

- Lymphocytes produce antibodies to fight against bacteria, viruses, and other potential pathogenic invaders.
- Neutrophils kill and digest bacteria and are the first line of defense during the onset of an infection.
- Basophils secrete chemicals such as histamine, a marker of allergic disease, that help to control the body's immune response.
- Eosinophils attack and kill invading parasites and cancer cells.

Note:
- Lymph contains plasma, carbon dioxide, proteins, glucose, and white blood cells. Red blood cells major nutrients present in the blood are absent in lymph.
- Ligaments are the connective tissues that attach bone to bone. Tendons are the connective tissue that links between a muscle and a bone. These two are dense regular connective tissues. Cartilage is the elastic connective tissue present between the joints to provide support and movement.
