The Structures And Types Of The Human Body Skeletal System

There are three main types of blood vessels: arteries, veins, and capillaries. Arteries are vessels that usually carry highly oxygenated blood away from the heart and to the rest of the body. (The pulmonary trunk and related arteries are exceptions, as they actually carry blood from the lungs toward the heart.) Because arteries must transport high volumes of blood being forcefully pumped out by the heart and must therefore withstand greater pressure, most have thick, muscular walls and are more flexible as well. Arterioles, smaller types of arteries with thinner walls, branch off of the arteries to carry blood to another type of vessel, called the capillary. Capillaries are the most abundant blood vessels in the body. Thinner and smaller than the other blood vessels, the role of capillaries is to exchange substances like water, gases, chemicals, nutrients, wastes, etc. with the tissues of the body. The third type of blood vessel is the vein. Although they are generally larger than the other blood vessels, veins tend to have thinner, less flexible walls, as they are not forced to deal with such high blood pressures. Venules (veins’ versions of arteries’ arterioles) connect the capillaries to the veins, which then transport blood back

The heart pumps the blood around the body through the blood vessels which is made of mostly veins and capillaries. The blood carries the dissolved oxygen around the bodily

Blood being carried by the veins is deoxygenated blood, blood that is high in carbon dioxide

Blood has many functions and is a complex structure of cells and fluid. It helps fight bacteria, protect the body from infection, carry valuable sources of minerals and nutrients around the body, dispose of waste materials, keeps the body temperature regulated and helps with glandular distribution of hormones and enzymes.

Blood is a red fluid that contains a complex mixture of cells suspended in a liquid matrix which is transported (circulated) throughout the body by the circulatory system of an organism. It circulates around the body by the heart and delivers oxygen and other important nutrients to cells of organs and tissues, while at the same time, removing waste product from our body. Blood is located in almost every part of our body, which is due to the network of blood vessels called the circulatory system. It is circulated through the body’s heart, arteries, veins and capillaries (tiny vessels that connect arteries and veins). In order for blood to carry out its functions, it needs to circulate all over our body to all living cells and tissues which it does through the support of the heart that pumps blood throughout our entire body). Thus, it is the fluid of life, a vital life force that all humans need in order to live and sustain life.

Blood is made up of straw coloured plasma, the matrix, in which various types of blood are carried. Plasma is mainly water where substances are carried such as oxygen and carbon dioxide, nutrients such as glucose and amino acids, salts, enzymes and hormones. Also there is a combination of important proteins which help with blood clotting, transport,

In this content am going to be talking and explaining the structure and function of the skeletal system. I will be talking about: Axial skeleton, Appendicular. Also highlighting the different types of bone such as long bones, short bones flat bones, irregular bones and sesamoid bones. I am also going to be talking about how your body is

When the bone has reached maturity the marrow is transformed into yellow bone marrow. (Jarmey, 2004).

Veins • Transport the blood to the heart • The lumen passage is large • Have dark red blood and is deoxygenated • The valves in the veins prevents back flow Arteries • The blood is bright red and there is oxygen in the blood • They are thick walled • Delivers nutrients to the cells in the body e.g. iron • The lumen passage is small Capillaries • They are thin walled • They allow a passage of gases and nutrients e.g. sodium and potassium • Brick red in

You could say the cardiovascular system is the most important system in the body. This system continuously delivers nutrients and oxygen to all cells throughout the body. The heart pumps oxygenated blood through approximately 60,000 miles of blood vessels within the human body. With that being said, if this system does not work, you are instantly dead and this is why I say it is the most important structure the body has. Three systems that could not survive without the cardiovascular system include the respiratory, integumentary and renal structures. Each system works with one another and plays a key factor in keeping our bodies alive.

Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues. Blood is pumped from the ventricles into large elastic arteries that branch repeatedly into smaller and smaller arteries until the branching results in microscopic arteries called arterioles. The arterioles play a key role in regulating blood flow into the tissue capillaries. About 10 percent of the total blood volume is in the systemic arterial system at any given time.

The blood delivers essential nutrients and oxygen which travels in the plasma, the liquid part of the blood. Another function is protection as the blood carries white blood cells which fight pathogen that have enter the body. Also the platelets that also travel in the blood help to clot blood from cuts this is so that the body does not bleed to death. The blood also carries antibody’s to fight of infections that it is specific to as it has been vaccinated against or exposed

Most of the time your blood in the arteries is loaded with oxygen and nutrients and the color is very bright red,that’s why when you look at your veins they look purple. There’s one artery that carries deoxygenated blood and there’s veins that carry oxygenated blood. We need to discuss the Heart and Lungs.The circulatory system is centred around the heart, a muscular organ that pumps your blood around a complex network of blood vessels extending to every part of the body. (Blood carries the oxygen and nutrients needed to fuel the activities of the body’s tissues and organs, and it plays a vital role in removing the body’s waste products. An average-sized adult carries about 5 litres (9 pints) of blood.f an adult’s blood vessels were laid end to end, they would stretch out over 100,000 km (62,500 miles).) Johnson, D. (2014, April 7).

The skeletal system is made up of bones and joints. Bones are a dry dense tissue that is composed of calcium phosphorous and organic matter. The bones are protected and covered by a layer of fibrous connective tissue membrane called the periosteum (Brown, et al., 2015, p. 1547). There are two basic types of bone tissue: Compact Bone and Spongy Bone. Compact bones are dense smooth bones, while Spongy bones are composed of small needle-like pieces of bones and open space. Bones are then categorised according to the shape of the bone into four groups: long, short, flat and irregular. Long bones characteristically are typically longer then they are wide and generally have a shaft with heads at either ends e.g. the humerus. They are mainly compact bones. Short bones

Bone serves the organism at multiple levels: As a system, bones permit the organism to locomote effectively and to maintain posture by bearing loads without deformation, by providing rigid attachment sites for muscles and acting as a system of levers to amplify small movements. As an organ, bones protect the viscera and house the hemopoietic tissue (red marrow). As a tissue, bones serve as a reservoir of readily mobilizable calcium, an
