Final answer:
Connective tissue is made up of cells and fibers, and includes a variety of types such as adipose tissue and blood. These tissues have critical roles in the body, including support, protection, and transport of fluids like blood and lymph. Muscle and nervous tissues also have distinctive functions and characteristics.
Step-by-step explanation:
Two components of connective tissue include cells and fibers. Connective tissue is made up of three essential components: cells, ground substance, and carbohydrate fibers. These tissues serve various functions such as holding tissues and organs in place, providing strength, and facilitating the circulation of bodily fluids. Examples of connective tissue include adipose tissue, which is composed of cells known as adipocytes, and blood, which consists of a fluid matrix called plasma that carries red blood cells (erythrocytes) and white blood cells (leukocytes).
The different types of connective tissues in animals can be classified into connective tissue proper (loose and dense), supportive connective tissue (such as bone and cartilage), and fluid connective tissue (such as blood and lymph). Additionally, there are three types of muscle tissues in animals, which are skeletal, cardiac, and smooth muscle tissues, each with specific functions. Nervous tissue, on the other hand, is responsible for transmitting signals throughout the body, crucial for brain function and response to stimuli.
