Simple squamous epithelium consists of one layer of thin, flat epithelial cells resting on a basement membrane formed of connective tissue. It is found in such places as the alveoli of the lung and lining blood vessels. Squamous epithelial cells are flat, tightly adherent to each other, thin, and have a smooth surface. Their minute thickness serves them well in the lung alveol. the alveoli are the site of gas exchange between the air in the lungs and the gases in the blood, which occurs by diffusion. The rate of diffusion is inversely dependent on the thickness of the surface through which diffusion occurs; the thicker the layers, the slower the diffusion. Gas exchange requires quick diffusion, therefore thin squamous epithelial cells are excellent for the job.Blood flow in blood vessels requires the lining surface of the vessels to be smooth, to reduce friction and aid blood flow. the smooth surface of squamous epithelial cells serves them well for this job as well.
Epithelial, for it has a glandular subdivisions.Epithelial TissueEpithelial Tissue's main purpose is to cover surfaces, and line the cavities. This means it also works with glands, glands are groups of cells specialized to produce a substance that is sent out to other parts of the body.There are two types of glands that go with Epithelial Tissue:1) Exocrine glands: these are the ducts that carry out the secretion, such as sweat, or oil for your hair follicles.2) Endocrine Glands: This depends on the blood flowing through the duct to carry the secretions to another organ. These secretions are hormones.Thus meaning that since the Endocrine Glands go with the Epithelial tissue it means that Epithelial tissue forms hormones.
3.cells in the nervous system are different in structure from cells in the circulatory system and they carry out different specialized functions
Nerves carry messages to the muscles to react. Nerves help us feel pain, heat, and cold.
no.. its basis as a molecular structure (nucleosides) means it cant carry out the functions of growth, reproduction, etc, hence it cannot be classified as an organism!
the act of breathing helps to drive venous blood out of the abdominal cavity source is linked

tissues form organs because they carry specialised cells which carry out certain functions, so the organs are formed to carry out these functions that's why they are made of tissues
Epithelial TissueConnective tissue is not the answer. The correct answer is epithelial tissue.Epithelial Tissue's main purpose is to cover surfaces, and line the cavities.

Proteins come in many forms and have many functions. Their structure determines their function. They can be enzymes which create reactions (catalysts), they can be antigens, they can be the building blocks of tissues, such as in muscle tissue, they can be hormones, just to name a few. They are what we rely on, and carry out all of the functions on a cellular level, and thus what makes us work.
Amino acids are the building blocks of protein, which plays a key role in essentially all biological processes. Because amino acids make up a huge proportion of our muscles, cells, and tissue, they carry out bodily functions like providing structure to our cells. They are also key for the healing and repair of wounds and damaged tissue.
tissue make up muscle tissue. bone cell grouped together make up nerve bone tissue.
They are organelles;
3.cells in the nervous system are different in structure from cells in the circulatory system and they carry out different specialized functions
Organs are a structure composed of one or more different types of tissues; specialized to carry out specific functions. Some examples of organs are heart, vein's, arteries, and capillaries.novanet...when two or more tissues combone their functions they form a structure called an organ
Nerve tissue, but it does much more than that - there are many nerve circuits that have no connection to the brain, performing their functions locally and unconsciously.
Veins, in most animal circulatory systems, carry deoxygenated blood from the tissues back to the heart.The exception are the pulmonary veins, which carry oxygenated blood to the heart.There is also a lining inside the veins made of epithelial tissue.
The function is it carries blood away from the heart, and the structure of the wall is is usually very thick, there is 3 layers of the wall. The first is Epithelial cells, the second is muscle tissue, and the last is a flexible connective tissue.
