Epithelia tissue : Epithelial tissue, the type of tissue that lines the surfaces and cavities of your body 's organs, epithelia may be composed of several layers of cells called compound epithelia or just a single layer known as simple epithelia.
Types of epithelia tissue include the simple epithelia and the compound epithelia:
Simple epithelia: Epithelia tissue can have cell shapes these are the Columnar, Cuboidal, and Squamous Cell Shapes. All this cells shapes are part of a type of an epithelia tissue which is the simple Epithelia. There are columnar cells, which means column-like cells and squamous cells, which are flattened and scale-like cells, simple squamous epithelia is found in walls of lung alveoli, blood capillaries and bowman’s

There is Keratinized and non keratinized the difference between the two is that keratinized covers the dry areas of the skin where as non keratinized covers moist areas such as the larynx, vagina.
Muscle
Muscles need food and oxygen in order to work properly so if they are working hard but have not got enough food or oxygen then it causes pain and cramps.
The strongest muscle is the ones on the side of your mouth that help you bite and chew food.
Cardiac Muscle the heart is made of a muscle called the cardiac muscle unlike other muscles in the body the cardiac muscle never gets tiered its constantly working and never stops. It squeezes blood out of the heart and then relaxes it to fill it back with blood again in and this process continues and happens everyday until you are dead. The heart beats non stop this is achieved because of the cardiac Muscle.
The cells of a cardiac muscle are shaped and wider and shorted than a skeletal muscle however they are stripped like skeletal
There are two different areas that are important for testing handgrip strength, those are anatomical and physiological. Anatomically, grip strength and muscle mass are related with a correlation factor (r) = 0.60. Handgrip strength develops mainly as a function of the muscles in the forearm, as well as the muscles in the hand. Physiologically, grip strength participants reach peaks of 0.3 s to 2.7 s. These results help to show that the energy pathway involved in maximal muscle strength comes from the phosphagen system, which is the primary biochemical reaction for strength. (Beam & Adams 2014).
The second layer of the skin is called the dermis and is also known as the middle layer. The dermis is what holds the body together. The dermis has layers to it as well as the epidermis. There are two layers to the dermis, the papillary layer and the reticular layer. The cells of the dermis are fibroblast, macrophages, mast cells, and scattered white blood cells (wbc’s). the dermis is richly supplied with nerve fibers and BV;s. dermal BV’s is also a part of the integumentary system, dermal BV,s have converging and diverging vessels that ar...
Question 1: Briefly describe, in 500 words or less, the normal structure and function of your chosen cell type. In your answer, discuss specific features in your chosen cell type, including cell organelles.
The walls of the intestine may contain a mucous membrane (epithelia, lamina propria, and muscularis mucosa), submucosa (muscularis externa, inner circular fibers, outer longitudinal fibers), and serosa (mesothelium, connective tissue) ("Epithelial Cells").
There are 4 different types of tissues in the human body, epithelial, connective, muscular and nervous. One of the main ones to look at with the lymphatic system is epithelial tissue. The epithelial tissues have many functions but the ones that affects the lymphatic system are diffusion and cleaning.
The epidermis and dermis are tissue layers that make up the skin (integument) covering the body. The layers (strata) of the epidermis range from four to five, depending on where they are on the body; and are classified into two types of skin: thin skin and thick skin. Most of the body is covered in thin skin, which has four layers. Areas of the body that are heavily exposed to stress and pressure (palm of hand and sole of feet) are covered in five layered thick skin. Thin skin has the following
The endothelium is a cell layer that is lined on the interior surface of lymphatic vessels and blood vessels, which are made up of endothelial cells (Dorland, 2012).
The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...
I knew it was epithelia as the cells on the slide were connected to form sheets that were attached to a basement membrane, two characteristics of epithelia tissue. (Urry, L.A. et al., 2017) Epithelia cells are polar meaning that they always have one side of the cell facing a lumen (cavity) which is another way I identified these cells as epithelial. (Urry, L.A. et al., 2017) I identified it was simple epithelia as there was only one layer of cells and they were all connected to the basement membrane. (Urry, L.A. et al., 2017 ) It was identified as cuboidal as the cells looked like squares. They were also identified as this as they had their nucleus placed centrally in the cells. (Mitchell, B.S. & Peel, S 2009) The tissue is also ciliated and this can be seen in the lumen as there are areas that are blurred in the slide which suggest cilia as the cells are smaller that of epithelia. (Mitchell, B.S. & Peel, S 2009)
One of the main organs of the cardiovascular system is the heart; the heart is made up of four chambers. The blood enters the right atrium of the heart from body through the venae cavae, it then travels though the tricuspid atrioventricular valve into the right ventricle. The blood is then pumped through the pulmonary semilunar valve out of the heart to the lungs using the pulmonary arteries. It is then oxygenated and returns to the left atrium in the pulmonary veins it travels through the mitral atrioventricular valve into the left ventricle and is then pumped out of the heart to the systematic circulatory system passing through the aortic semilunar valve into the aorta. (Widamaier, et al 2011:359)
The connective tissue is the most abundant and widely distributed in complex animals. It is made up of a matrix consisting of living cells and non-living substance called ground substance. The ground substance is made of an organic substance (protein) and an inorganic substance (usually a mineral or water). It separates the cells and varies in consistency from solids to semifluid to fluid. The principal cell of connective tissue is the fibroblast which makes the fibers found in nearly all connective tissues. There are three kinds of fibers; the white collagen fibers contain collagen, a protein that gives them flexibility and strength. Reticular fibers are very thin collagen fibers that are highly branched and form delicate supporting networks. The yellow elastic fibers contain elastin; a protein that is not as strong
Heart is an organ of the cardiovascular system. Heart is responsible for supplying oxygen to all parts of the body. The heart is about the size of a clenched fist. It is located just to the side of the centre of the chest. It is surrounded by a protective membrane called the pericardium. The heart is divided into left and right sides. Heart is made up of muscle and it has walls. It contacts to pump blood into the blood vessels and all over your body. The heart beats to maintain the blood circulating. The heart beating leads the cardiac cycle and which pumps blood to the cells and tissues of the body.
Your heart is a special type of muscle. Previous to each beat, your heart fills with blood. To get the blood circulating, the muscle contracts. The heart is similar to a pump; the right side takes in the blood from the body and pumps it into the respiratory system, the lungs. The left side pumps the blood to the body and receives the blood from the lungs. The left side and right side's functions are opposite from each other.
Epithelial tissue covers the surface of the human body and lines most internal cavities. Epithelial tissue is found in the body’s skin, lining of the stomach and intestines, the kidney, and glands, as well as other locations within the body (Amsel, 2012). The two types of epithelial tissue are (1) covering and lining epithelium and (2) glandular epithelium. The covering and lining epithelium are found lining the integumentary, digestive, cardiovascular, and respiratory systems as well as the ventral body cavity and the organs this cavity houses (Hoehn, et al., 2007, p. 118). The glandular epithelium is found within the glands of the entire human body. Not only are their two types of epithelial tissue found in the human body, there are also multiple classifications and various shapes. These classific...
