Question

h it uses a enrc Ora eta to permit only specific molecules to cross the membrane. Active transport is another form of moving substances across the membrane but it goes against the concentration gradient. Thus it moves chemical substances from an area of le concentration to an area of haa concentration. The other difference in active transport is that ATP a form of energy is required in order for this type of transport to occur. The last type of diffusion is known asand it is part of the immune system. 10. There are four types of tissue in the body , and There characteristics include: Picture of Tissue Type of Tissue Characteristics Four types of tissue Connective tissue Epithelial tissue Muscle tissue Nervous tissue

Explanation / Answer

Thus it moves chemical substances from an area of low concentration to an area of high concentration. The other difference in active transport is that ATP a form of energy is required in order for this type of transport to occur. The last type of diffusion is known as facilitated diffusion. The four types of tissue in the body connective tissue, epithelial tissue, muscle tissue and nervous tissue.

Connective tissue is the most abundant and widely distributed of the primary tissues. It has three main components: cells, fibers, and ground substance. Together the ground substance and fibers make up the extracellular matrix.

In epithelial tissue, cells are closely packed together. Since they form the linings of organs and body cavities, they have at least one side that's not in contact with other cells. They lack blood vessels and obtain nourishment through diffusion.

In muscle tissue, muscle cells share several properties: contractility, excitability, extensibility, and elasticity: Contractility is the ability of muscle cells to forcefully shorten.

Integration and communication are the two major functions of nervous tissue. It contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses.
