Answer:
Epithelial tissue covers the outside of the body and lines organs, vessels (blood and lymph), and cavities. Epithelial cells form the thin layer of cells known as the endothelium, which is contiguous with the inner tissue lining of organs such as the brain, lungs, skin, and heart.
explain how cell arrangement helps this body part perform its function. :
Its tightly packed cells allow for protection against harmful substances.
Explanation:
Epithelial tissue covers the outside of the body and lines organs, vessels (blood and lymph), and cavities. Epithelial cells form the thin layer of cells known as the endothelium, which is contiguous with the inner tissue lining of organs such as the brain, lungs, skin, and heart. The free surface of epithelial tissue is usually exposed to fluid or the air, while the bottom surface is attached to a basement membrane.
The cells in epithelial tissue are very closely packed together and joined with little space between them. With its tightly packed structure, we would expect epithelial tissue to serve some type of barrier and protective function and that is certainly the case. For example, the skin is composed of a layer of epithelial tissue (epidermis) that is supported by a layer of connective tissue. It protects the internal structures of the body from damage and dehydration.
Epithelial tissue also helps to protect against microorganisms. The skin is the body's first line of defense against bacteria, viruses, and other microbes.
Epithelial tissue functions to absorb, secrete, and excrete substances. In the intestines, this tissue absorbs nutrients during digestion. Epithelial tissue in glands secrete hormones, enzymes, and other substances. Epithelial tissue in the kidneys excrete wastes, and in the sweat glands excrete perspiration.
Epithelial tissue also has a sensory function as it contains sensory nerves in areas such as the skin, tongue, nose, and ears.
Ciliated epithelial tissue can be found in areas such as the female reproductive tract and the respiratory tract. Cilia are hair-like protrusions that help propel substances, such as dust particles or female gametes, in the proper direction.

The day of Josephine and Cora's campout had finally arrived. The two friends had been planning the campout for more than two weeks. They picked out a spot for the tent in Josephine's backyard. They chose the games they wanted to play. Now they were at the store with Josephine's dad buying camping food. "This campout is going to be perfect," Cora said as she dropped a bag of marshmallows into the cart. "We have the perfect tent, the perfect games, and the perfect food!"
Just then a loud clap of thunder sounded outside. The wind whipped as a bright flash filled the dark sky.
"But not the perfect weather," Cora moaned.
"That was thunder and that means rain. Rain means no camping," Josephine groaned.
"I guess we can stop shopping!" Cora snapped. She began taking food out of the cart.
As Josephine's father placed the food back in the cart, he told the girls not to give up on their campout. They paid for the food and went back to Josephine's house to wait out the storm.
At dinnertime the sky remained dark gray as the rain continued to pour down outside. The girls sat in silence while they ate. Cora looked out the window and said sadly, "I can't believe it's still raining. Our campout was supposed to be perfect."
What did Cora mean when she said, "This campout is going to be perfect"?
A) Cora's parents' house was the best place to host a campout.
B) Cora planned the campout to bond with her perfect friend, Josephine.
C) They made a lot of plans and collected a lot of stuff for camping.
D) Josephine and Cora's campout would celebrate their perfect attendance for not being absent from school.
