The hard outer layer of bones is composed of compact bone tissue, so-called due to its minimal gaps and spaces. Organismal level— The organismal level is the highest level of organization. The heart and circulatory system simply facilitate the movement of this travelling tissue. The four basic tissue types in humans include epithelium, connective, muscle and nervous tissue. The nervous tissue is mostly part of the brain and the spinal cord which is controlled by neurons. Therefore it is different from other muscles. Ribosomes — It is a cell structure that makes protein.
May 16, 2013 Levels of Structural Organization in the human body The human body has 6 main levels of structural organization. It allows blood vessels to pass through and nourish the brain. It supplies energy not only to heart muscle for blood circulation and skeletal muscle such as for gross body movement , but also to the chromosomes and flagella to enable them to carry out their many functions. These cells would not be able to function on their own, they are all part of a large organism that is called — you. A culture is a set of norms, values, beliefs and goals shared by members of society. They are found lying on the basement membrane for support. The first type of tissue found in the human body is epithelial tissue.
The passage from the bladder to the exterior is via the urethra. Epithelial tissue which is only one cell thick is known as simple epithelium. Like electrical circuits, the nervous system transmits signals from nerves to the spinal cord and brain. The primary function of this type of epithelium is absorption of nutrients, secretion of digestive juices as well as secretion of mucus by goblet cells. P3- Outline the gross structure of all the main body systems Cardiovascular system Purpose- the purpose of the cardiovascular system is to carry blood throughout the body. Its main role is to store energy in the form of lipids, although it also cushions and insulates the body. They make the energy that cells need to do to work correctly.
The basic function of value consensus is to make social order possible. Hazards are referred to as anything that can cause harm to someone. Cuboidal cells are cube-shaped while columnar cells are elongated and rectangular. Then we will build our way into the frame work. The Male Reproduction System has two testes that hang in a skin sac called the scrotum, just outside the abdomen, and are connected by long tubes each known as vas deferens to the urethra. Serosa is made up of loose connective tissue and coated in mucus to prevent friction damage from the intestine rubbing against other tissue. Structural elements of connective tissue: Connective tissues consist of three parts: cells suspended in a ground substance or matrix; and most have fibers running through it.
Muscle tissue contains the specialized proteins actin and myosin that slide past one another to allow movement. Cartilage is a flexible connective tissue found in many areas in the body including the joints between bones, the rib cage, the ear, the nose, the elbow, the knee, the ankle, the bronchial tubes and the intervertebral discs. Everybody speaks informally different from one and other. Simple Epithelia is one thick layer of tissue made from cells, it can be one of these three different shapes: 1. Chien 2012 Working tissue inside the heart. They are self-contracting, autonomically regulated and continue to contract in rhythmic fashion for the whole life of the organism. Sorry, but copying text is forbidden on this website! They are called pith rays or medullary rays.
Words: 5589 - Pages: 23. Ciliated epithelium cells often contain goblet cells which secrete mucus. The second type of tissue found in the body is connective tissue. The function of the areolar is to hold the organs in place, it attaches the epithelia tissues to other underlying tissues. Cellular level — the cellular level is made up of the smallest unit of living matter, the cell. Organizational chart identifies positions, job title, authority, etc.
Examples of this include the brain, stomach and liver. They were all taking part in the activity and sharing the equipment with each other. Epithelial Tissue It covers the whole surface of the body and it can be identified by one cell attached to another and is one cell thick or it sometimes has multi layers of thickness. Punishment is when something undesirable is received after a certain behaviour in order to make that behaviour stop. Compound Epithelium — this type of epithelial tissue is made to withstand wear and tear. Tissues All cells group together within the body to form tissue, a collection of similar cells group together to perform a specialized function. These cells can be flat, cuboidal, or columnar.
They are arranged in parallel lines and are bundled, making muscle tissue very strong. The lowest layer of cells on the basement membrane keenly divides and pushes the older cells upwards. Skeletal System Skeletal system is made up of your bones, ligaments, and. Simple epithelium is usually found on absorptive or secretory surfaces, where it helps to speed up these processes due to the single layer of cells. This means people may pass poor quality food off as good food to make money. Social order is only possible so long as members of society agree on these norms and values.
The Endocrine System is a collection of ductless glands distributed throughout the body. Cardiac muscle: This type of muscle is found only in the four chambers atria and ventricles of the heart. Outline the structure of the main tissues of the body. Outline the structure of the main tiOutline the structure of the main tissues of the body. Organelles are the various components of a cell with a specific structure and function and are linked to miniature organs. Bone is the mineralization factor. The function of these tissues are to move materials blood , give support areolar and cartilage , and reinforce and defend bones.
