Which among the following is not a connective tissue?

Blood
Bone
Skin
Cartilage

The correct answer is D. Cartilage.

Connective tissue is a type of tissue that supports, connects, or surrounds other tissues and organs of the body. It is made up of cells and fibers that are embedded in a matrix. The matrix is a gel-like substance that provides support and structure to the tissue.

Blood, bone, and skin are all connective tissues. Blood is a fluid connective tissue that carries oxygen and nutrients to the body’s cells. Bone is a solid connective tissue that provides support and structure to the body. Skin is a protective connective tissue that covers the body.

Cartilage is a type of connective tissue that is found in many parts of the body, including the joints, the nose, and the ears. It is a flexible and elastic tissue that helps to cushion and protect the bones.

Here is a brief explanation of each option:

  • Blood is a fluid connective tissue that carries oxygen and nutrients to the body’s cells. It is made up of plasma, red blood cells, white blood cells, and platelets.
  • Bone is a solid connective tissue that provides support and structure to the body. It is made up of cells, minerals, and proteins.
  • Skin is a protective connective tissue that covers the body. It is made up of three layers: the epidermis, the dermis, and the hypodermis.
  • Cartilage is a type of connective tissue that is found in many parts of the body, including the joints, the nose, and the ears. It is a flexible and elastic tissue that helps to cushion and protect the bones.
