can you help me with the above questions. please
Answers
Answer:
1) The animal tissues are divided into c, connective, muscular and nervous tissues.
2) There are 8 types of epithelial tissues. Simple squamous, Stratified Squamous, Simple Cuboidal, Stratified Cuboidal, Simple Columnar, Stratified Columnar, Pseudostratified Columnar and Transitional epithelia or urothelium.
3) Epithelial tissue or epithelium forms the outer covering of the skin and also lines the body cavity. It forms the lining of respiratory, digestive, reproductive and excretory tracts. They perform various functions such as absorption, protection, sensation and secretion.
4) The glandular epithelium is made up of cuboidal or columnar cells. They are specialised for secretion. The columnar or cuboidal epithelium may bear cilia and are referred to as ciliated epithelium.
5) Connective tissue with a fluid matrix is (1) Ligament (2) Tendons (3) Blood (4) Cartilage. Connective tissues imply support and connect different tissues and organs of the body. ... Blood is an example of loose connective tissues, they are present all over the body, which provides both support and elasticity.
6) One of the most complex organ system to ever evolve, the human nervous system consists of two parts, namely: Central Nervous System (consists of the brain and spinal cord) Peripheral Nervous System (includes all the nerves of the body).

Answer:
1. There are four types of tissues found in animals: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
2. Simple epithelial tissues are generally classified by the shape of their cells. The four major classes of simple epithelium are: 1) simple squamous; 2) simple cuboidal; 3) simple columnar; and 4) pseudostratified.
3. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.
2. The cells in epithelial tissue are tightly packed together with the very little intercellular matrix.
4. Simple columnar epithelium is a single row of tall, closely packed cells, aligned in a row. These cells are found in areas with high secretory function (such as the wall of the stomach), or absorptive areas (as in the small intestine ).
5. Blood and lymph are fluid connective tissues. Cells circulate in a liquid extracellular matrix. ... Nutrients, salts, and wastes are dissolved in the liquid matrix and transported through the body. Lymph contains a liquid matrix and white blood cells.
6. Nervous tissue is composed of neurons, also called nerve cells, and neuroglial cells. Four types of neuroglia found in the CNS are astrocytes, microglial cells, ependymal cells, and oligodendrocytes. Two types of neuroglia found in the PNS are satellite cells and Schwann cells.
