ANATOMY

Detailed explanation-1: -A nonliving material, called the intercellular matrix, fills the spaces between the cells. This may be abundant in some tissues and minimal in others. The intercellular matrix may contain special substances such as salts and fibers that are unique to a specific tissue and gives that tissue distinctive characteristics.

Detailed explanation-2: -Connective tissues are fibrous tissues made up of cells separated by non-living material, which is called an extracellular matrix. This matrix can be liquid or rigid. For example, blood contains plasma as its matrix and bone’s matrix is rigid.

Detailed explanation-3: -All cells and tissues in the body derive from three germ layers: the ectoderm, mesoderm, and endoderm. Membranes are layers of connective and epithelial tissues that line the external environment and internal body cavities of the body.

Detailed explanation-4: -Organs, such as the heart, the lungs, the stomach, the kidneys, the skin, and the liver, are made up of two or more types of tissue organized to serve a particular function.

Detailed explanation-5: -Organs are structures in the body that are made up of two or more tissue types depending on their function that work in conjunction to perform a specific function for the body. When multiple organs work together to perform a function they are called an organ system.
