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
It is much thicker than the epidermis and contains collagen, reticular and elastic fibers, and is vascular. The area where the dermis meets the epidermis is unique in that the epidermis contains ridges at the stratum basale layer which interlocks with the dermal papillae, which are upward projections, like waves, on the uppermost surface of the dermis. The dermis had two sublayers. The papillary layer is in the dermal papillae and near it and is made up of areolar tissue. The reticular layer is dense irregular connective tissue that is found at the basal end of the dermis and contains collagen and adipose
The heart is an extraordinary structure that is the base of all human life. However, it similar to the uncomplicated functions of water pumps. As the heart beats, blood is distributed throughout the body using a network of blood vessels. The functions of the heart can be kept in regular and healthy conditions through exercise. Exercise has an effect on the blood that is circulating through the body. That circulating blood makes the heart desire more oxygen, causing the heart rate to increase rapidly to keep up with activity demand.
The heart is two sided and has four chambers and is mostly made up of muscle. The heart’s muscles are different from other muscles in the body because the heart’s muscles cannot become tired, so the muscle is always expanding and contacting. The heart usually beats between 60 and 100 beats per minute. In the right side of the heart, there is low pressure and its job is to send red blood cells. Blood enters the right heart through a chamber which is called right atrium. The right atrium is another word for entry room. Since the atrium is located above the right ventricle, a mixture of gravity and a squeeze pushes tricuspid valve into the right ventricle. The tricuspid is made up of three things that allow blood to travel from top to bottom in the heart but closes to prevent the blood from backing up in the right atrium.
Human skin is a multi-layered structure. It is generally divided into two layers, the epidermis and the dermis. Below the dermis a subcutaneous fat layer is found. The epidermis can be further divided into several sub-layers. These are the stratum corneum, the stratum lucidum, the stratum granulosum, the stratum spinosum, and the stratum germinativum. The stratum germinativum is usually referred to as the basal layer.
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 mucosa in the colon is composed of simple columnar epithelium and unlike the mucosa of the small intestine it contains no villi or plicae circularis . Although, it does contain crypts.
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...
Everyone knows that the heart is a vital organ and we cannot live without it. It is complex and important; therefore it is critical to know how it works. With knowledge about the heart and what is good and bad for it, one can significantly decrease the risk for diseases. Now, the heart has three layers. Endocardium is the smooth inside lining, myocardium id is the middle layer of heart muscle, and it is surrounded by a fluid filled sac called the pericardium. The heart is split into four parts; some may call it chamber or rooms. These parts are the: right atrium, the left atrium, the right ventricle, and the left ventricle. The chambers are separated by partition walls known as the septum and each has a one-way valve that prevents blood from flowing backwards.
The heart is situated in the thoracic cavity protected by a sac called the pericardium. The inner heart wall is made up of three layers the outside of the heart wall is called the epicardium this lubricates the heart and prevents friction. The middle and thickest layer of the heart, called the myocardium, is a thick muscular layer built up of cardiac muscle which is responsible for pumping blood. The thickness of the myocardium varies throughout the heart, the atria does not need as much myocardium as the ventricles as the atria only need enough pressure to pimp the blood to the ventricles whereas the ventricles need enough pressure to pump blood to the lungs and the body. The left ventricle has a thicker myocardium layer than the right as the le...
The heart is a pump with four chambers made of their own special muscle called cardiac muscle. Its interwoven muscle fibers enable the heart to contract or squeeze together automatically (Colombo 7). It’s about the same size of a fist and weighs some where around two hundred fifty to three hundred fifty grams (Marieb 432). The size of the heart depends on a person’s height and size. The heart wall is enclosed in three layers: superficial epicardium, middle epicardium, and deep epicardium. It is then enclosed in a double-walled sac called the Pericardium. The terms Systole and Diastole refer respectively and literally to the contraction and relaxation periods of heart activity (Marieb 432). While the doctor is taking a patient’s blood pressure, he listens for the contractions and relaxations of the heart. He also listens for them to make sure that they are going in a single rhythm, to make sure that there are no arrhythmias or complications. The heart muscle does not depend on the nervous system. If the nervous s...
The cytoskeleton is a highly dynamic intracellular platform constituted by a three-dimensional network of proteins responsible for key cellular roles as structure and shape, cell growth and development, and offering to the cell with "motility" that being the ability of the entire cell to move and for material to be moved within the cell in a regulated fashion (vesicle trafficking)’, (intechopen 2017). The cytoskeleton is made of microtubules, filaments, and fibres - they give the cytoplasm physical support. Michael Kent, (2000) describes the cytoskeleton as the ‘internal framework’, this is because it shapes the cell and provides support to cellular extensions – such as microvilli. In some cells it is used in intracellular transport. Since the shape of the cell is constantly changing, the microtubules will also change, they will readjust and reassemble to fit the needs of the cell.
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.
Muscles are very vital to the human body and as seen above mankind could not survive without this system. It helps for energy, movement, temperature stabilization, pumps blood, and keeps everything working properly as well as many more things. Muscles don’t just do it all by themselves though, muscles work with every other system in the body especially the nervous system because that is were in gets all of its impulse signals from the brain so that the muscle are able to do the things they are capable of.
Simple cuboidal epithelia can be from many glands but since the tissue in the slide is ciliated it is likely to be a gland or organ that would absorb molecules such as kidney tubules, lining of ducts in the liver. (Mitchell, B.S. & Peel, S 2009) (Urry, L.A. et al.,
There are three simple tissues namely, parenchyma, collenchyma, and sclerenchyma. Parenchyma is thought of as the ground tissue of an axis since it occurs in greatest abundance and is the tissue in which the vascular tissues are embedded. Parenchyma cells may be isodiametric in both the pith and the cortex, but are more mostly longitudinally elongated in the cortex. They have comparatively thin walls. Wall layers are continuously shaped regions. These simple pits usually occur opposite each other, forming pit-pairs in the walls of contiguous cells. Plasmodesmata (specialized strands of endoplasmic reticulum) form interconnections with the protoplasts of adjacent living cells through simple
