A human body built in with various types of cells. Fundamental unit of life in a human body is cell. A matured human body is made up trillion of cells and depend on body environment to live and function. Cells, tissues and organs perform a different function in the body. To maintain a constant internal environment for well being, individual cells of the body required three important component oxygen, nutrients and removal of waste.
1.5) judge by using some examples; write the importance of maintaining a constant internal environment in different condition at high temperature, low temperature, severe vomiting and too much fluid intake. Homeostasis is the procedure through which a life form keeps up certain interior conditions, for example, a human body 's inward systems keeping up body temperature at a particular level to anticipate over or under warming; this procedure is vital in light of the fact that it makes it workable for cells and organs to work legitimately. For instance, certain parts of the human body stop to work on the off chance that they turn out to be excessively hot or excessively frosty; this is the reason it is feasible for individuals to stop to death
The Cardiovascular System (Known as circulatory system) is an important system within the human body which functions with specific organs such as the heart, blood vessels – including capillaries, veins, and arteries along with small blood vessels, and blood. The cardiovascular system works by your inhaling process. As you inhale, the air goes towards your lungs. Since the air contains oxygen, your blood stream absorbs this through your lungs.
CONCEPT 5: NURSING ASSESSMENT OF RESPIRATORY SYSTEM This concept is taken from Block 4, Module 6 which is entitled as ‘Assessment of respiratory system’. The respiratory system comprises of different organs used in respiration. Respiration involves inhalation and exchange of oxygen and carbondioxide between living organisms and the environment. The organs of respiration include; the nose, pharynx, larynx, trachea, 2 bronchi, bronchioles, 2 lungs and muscles of breathing (the intercostal muscles and the diaphragm).
Metabolism is the chemical process that occurs in every living organism to maintain its life. Without it, an organism would ultimately die because metabolism is the powerhouse of an organisms body, creating energy to make it work and function. There are two different processes that occur in metabolism, these processes are called catabolism and anabolism. In the catabolism process molecules breakdown, these molecules include carbohydrates, proteins, and fats. When they breakdown they go into a simpler form, which is then used to create energy that the body can use.
Anatomy and Physiology Assignment 2 – Essay The Lymphatic System The lymphatic system has three primary functions. It drains excess interstitial fluid from tissue spaces and returns it to the blood, enabling circulatory blood volume to be maintained; transports lipids and lipid-soluble vitamins A, D, E, and K absorbed through the gastrointestinal tract; and is responsible for the body’s adaptive (specific) immunity, ie. defences against microbes that breach its innate (non-specific) immunity (eg. skin, fever, inflammation): it adjusts or adapts to perform specific responses to specific microbes.
CT scans, an external test using a Computed Tomography machine to take multiple x-Rays of the digestive tract to find out what is going on. Both the CT scan and the standard x-ray will likely require you to ingest a substance that helps the digestive tract appear on the x-ray. The doctor may give you a barium enema to highlight the structures in your lower GI tract, so the doctor can see exactly what is going on in the digestive tract. The doctor may require you to eat solid food containing a substance called barium, then on the machine this will tract the barium as it passes through your digestive tract. They also may have the patient swallow special markers and have several different x-rays taken to track their passage through the digestive system.
Digestion of materials by endocytosis: Lysosomes may fuse with vesicles or vacuoles formed by endocytosis and release their enzymes into it for digestion. The material for digestion may be food (protozoa) or a foreign body like parasite (defense purpose) .The products of digestion are absorbed and assimilated leaving undigested which are released outside through exocytosis (vacuole migrates and attach with cell membrane and release its contents). 2. Autophagy: process by which unwanted structures within the cell are engulfed and digested within lysosomes .they first enclose by single membrane ,usually derived from smooth ER and structure then fuses with a lysosomes to form an “autophagic vacuole”, In which the unwanted material are digested.
This process is chemically balanced as each site along the digestive tract has a different degree of acidity that allows certain enzymes to function while restraining others. Each specific enzyme can bind to only one specific substrate, or group of allied chemical substances. After leaving the stomach, food pulp enters the upper portion of the small intestine where the pancreas (digestive organ that feeds enzymes into the gut) provides pancreatic enzymes to further break down the
As long as there is blood flowing through the body, the body strives to maintain homeostasis. For example, should one exercise, the body metabolises blood faster due to the need for oxygen around the body meaning the heart pumps faster to meet the demands of the body, in turn maintaining equilibrium and homeostasis. √ Blood is a vital tissue in sustaining life, health and wellbeing. Made up of various components its key task is to transport messages, deliver oxygen and other important minerals and gasses all over the body, whilst also acting as the body’s waste management service. The blood is made up of plasma (55%) and cells (45%) and makes up approximately 7% of one’s body weight Within plasma are both erythrocytes (red blood cells, RBC) and leukocytes (white blood cells, WBC) both of which are
The liver has a portal vein as well as a hepatic vein. It also has unique exchange blood vessels similar to capillaries, called “sinusoids.” How do these unique structures determine the function of the organ? • The livers main function is to filter and process the blood it receives. The portal vein and hepatic vein then deliver the nutrient rich blood to the capillaries (sinusoids).
How the cardiovascular system works? Image result for the cardiovascular system heart without labels The cardiovascular system consists of two circuits that blood travels through; pulmonary and systemic. Exercise has an impact on these systems, causing the heart to pump blood faster around the body, which allows you to exercise for longer.
Unit 5 Anatomy and Physiology for Health and Social Care P4 Explain the physiology of two named body systems in relation to energy metabolism in the body The two body systems selected in relation to energy metabolism in the body are the digestive system and cardiovascular system. The digestive system breaks down foods and the cardiovascular system enables absorption and usage of the food. The term energy metabolism in the body relates to chemical reactions that that maintain cells and organisms. It is divided into two categories: catabolism is the breakdown of molecules to obtain energy and anabolism the synthesis of all compounds needed by the cells.
