Discuss The Anatomical Features Of The Human Body

Complete the table below for the required systems listed. You are required to list four to six of the main organs of each body system, one or two sentences explaining the function of the system itself in your own words, and a short list of five to six major diseases that afflict each system.

The cardiovascular system is the process of the heart pumping the blood around the body through blood vessels, arteries, veins and capillaries. The main functions of the system are to transport materials to and from the cells around the body, to assist in temperature, to keep the levels of fluid in the body at the correct level, to distribute heat around the body and to defend the body. This system is the heart, which is a muscle that pumps blood around the body through arteries, veins and capillaries. Blood transports oxygen to the body cells which helps them to metabolise energy in the body. During this process the blood is also getting rid of any waste products of respiration, carbon dioxide and water. Blood also helps to supply heat, hormones, nutrients, salts and urea around the body. The heart is placed in between the lungs which is protected by the rib cage and is the size of a fist.

The cardiovascular system is part of the larger circulatory system, which circulates fluids throughout the body. The circulatory system includes both the cardiovascular system and the lymphatic system. The cardiovascular system moves blood throughout the body, and the lymphatic system moves lymph, which is a clear fluid that’s similar to the plasma in blood.

Blood is a bodily fluid that transports oxygen and nutrients to the cells within the body. Blood has plasma that lets the different types of blood travel round the body. Plasma contains proteins that have different functions for the blood- clotting, transporting and defence organisms and osmotic organisations. The plasma carries the red blood cell which has a elastic membrane so it can fit through the small capillaries within the body. Red blood cells can be also known as erythrocytes they don’t have a nucleus when they are matured which gives a bigger space for oxygen, although as there is no nuclei the red blood cells can’t divide so they only live for around 120 days. Red blood cells gain their colour from haemoglobin, oxygenated blood which is known as arterial blood which flows through the arteries coming from the heart and

The cardiovascular system consists of the heart, blood and blood vessels. The cardiovascular system is the major transport of materials to and from the cells. Blood is carried from the heart around the body via the arteries and the blood is then carried back to the heart via the veins. The

The main function of the cardiovascular system in relation to energy is to transport the oxygen and glucose to the cells, and to transport the waste products such as carbon dioxide and urea (waste product from protein digestion) away from the cells and to the lungs or kidneys.

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.

The diaphragm contracts when the ribcage moves up. The diaphragm relaxes when the ribcage move downs. Task 3 Describe the role of the following in relation to the respiratory system • Muscles • Blood • Nervous system Muscles Muscles control the process of inhaling and exhaling. The intercostal muscles contract and move the ribcage up and out while the diaphragm contracts, this increases the pressure inside the thoracic cavity which causes oxygen to drawn in. when the intercostal muscles relax and move the ribcage down and in and the diaphragm relaxes, this decreases the pressure inside the thoracic cavity which expels the carbon dioxide.

1. Name and describe the function of each major organ system in the body. a. Integumentary system – The integumentary system consists of the hair, skin, and nails and is the largest organ in the human body. It acts as a protector of the deeper body systems, maintains and regulates body temperature, and helps to eliminate waste and toxins from the body. It also senses touch and pressure as well as temperatures and pain.

The Circulatory system is responsible for the transport of blood throughout the body. The Circulatory system has many organs. The main components are the heart, the blood, and the blood vessels. It also consists of arteries, arterioles,

Exhalation, (breathing out), is the opposite of inhalation and occurs when the inspiratory muscles relax causing the diaphragm to depress which decreases the lung volume. This decrease in volume causes the alveolar pressure to increase therefore the carbon dioxide in the lungs flows from a high pressure to a lower pressure in the atmosphere. (Tortora & Derrickson, 2011)

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.

Composed of the heart, blood vessels, and blood, the cardiovascular system is the body system that carries out the tasks of pumping and transporting blood, oxygen, nutrients, and waste products, and other substances throughout the body.

The main organs of the respiratory system are the lungs – they are the location where the gas exchange between oxygen and carbon dioxide takes place. The lungs therefore expand when you breathe in, and retract when you breathe out. This is done through the diaphragm – a sheet of muscle that is positioned under the lungs. As one inhales, their diaphragm contracts and moves itself downward, increasing the space for your lungs to expand to. The ribs also move to enlarge the possible area the lungs can expand to. This pressure causes air to be sucked through the body to the lungs. When one exhales, the opposite takes place – the diaphragm moves upwards and returns to normal, allowing the process to happen again.
