Answers
a)muscular tissue.
The main function of the muscular system is movement. Muscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body & the maintenance of the body posture & body position.
b)connective tissue.
The function of this type oftissue is to provide structural and mechanical support for other tissues, and to mediate the exchange of nutrients and waste between the circulation and other tissues. Thesetissues have two principal components, an extracellular matrix and a variety of support cells.
c)areolar or loose connective tissue.
Areolar connective tissues hold organs in place and attaches epithelial tissueto other underlying tissues. It also serves as a reservoir of water and salts for surrounding tissues. Almost all cells obtain their nutrients from and release their wastes into areolar connective tissue.
d)dense regular connective tissue .
Dense regular connective tissue. Dense regular connective tissue provides connection between differenttissues in the human body. The collagen fibers in dense regular connective tissue are bundled in a parallel fashion.
e)adipose tissue .
Adipose tissue. Its main role is to store energy in the form of fat, although it also cushions and insulates the body. Obesity in animals, including humans, is not dependent on the amount of body weight, but on the amount of body fat - specifically adipose tissue.
f)skeletal tissue .
Through contraction and relaxation, skeletal muscleshelp to support and move our body. Additionally, skeletal muscles help with nutrition and temperature regulation. For the purposes of this study,skeletal muscle functions will be divided into two general categories - that is, support and movement and homeostasis.
g)bone .
Bones have many functions. They support the body structurally, protect our vital organs, and allow us to move. Also, they provide an environment for bone marrow, where the blood cells are created, and they act as a storage area for minerals, particularly calcium
h)cartilage.
Cartilage connective tissue is important because it provides support, but is less rigid than bone. It also allows for some flexibility of movement, but has more stability than muscle. The extracellular matrix of cartilage is produced by cells called chondroblasts.
