Chapter twenty is the last one of the circulatory system and it discussed about the blood vessels and circulation. Blood vessels is the distribution network or the network of tubes. There are three main blood vessels in the heart there are artery, veins and lymphatic. The arteries are all the blood vessels that take blood out from the heart. It tends to be thick, strong and tough because all the blood is rushing through the arteries. The arterioles are like the mini arteries that branch off of the arteries. Capillaries are the smallest blood vessels that comes off from the arteries and physically takes blood, oxygen and nutrients inside the blood to the cells that need it. It connects the arteries and vein and the it main function is to exchange

This report will focus on the endocrine system and how it is supporting the body to function well. The link between the effects of the endocrine system and type 2 diabetes will be highlighted. A clear distinction of normal endocrine functions will be explained and in addition the effects due to the condition of type 2 diabetes. The normal human body consists of two main systems which work together to sustain homeostasis. The two systems involved are the nervous system and the endocrine system. (1)

Unit D: Human Systems in Biology 20 is one of the main sections that becomes relatable to the Program of Studies (POS) for the Heart Rate and Exercise LabQuest activity. General Outcome #2 focuses on how students will explain the role of the circulatory systems and defense systems in maintaining an internal equilibrium. This further goes into measuring the students level of understanding the concepts of heart rate and the factors that affect it (Alberta Education, p. 41). Heart rate can then branch out into concepts of maximum heart rate, resting heart rate and recovery time. Through the LabQuest experiment, the main affecting factor was exercise and how that relates back to the fitness level of an individual [20-D2.3s]. Other key concepts found in the lab’s analysis questions then dealt with disorders of the heart [20–D2. 2sts]. Students are additionally "conducting investigations into relationships between and among observable variables" through the use of tools to gather information in regards to their heart rates [20–D2.2s]. Through group work activities, they are achieving collaborative work in measuring heart rate and other factors relating to the circulatory system [20-D2.4s]. To analyze and interpret, the POS explicitly states that students have the option in determining, from available data, the relationship between blood pressure and exercise [20–D2.3s a]. For the simulation, predominantly at the high school level, the

What is diabetes mellitus, and what action can I take to manage my Diabetes? Diabetes is a disease that affects the body systems that include; nervous system, integumentary system, genitourinary system, cardiovascular system, circulatory system, and endocrine system. In the Chinese traditions they see diabetes as having a yin deficiency or having an excessive amount of yang that is causing disharmony between the elements that provide nourishment to you spleen and pancreas. The medical and nutritional approach interconnects when investigating the individual cause of the increase susceptibility to diabetes mellitus.

The tilt study demonstrated the baroreflex response of the human cardiovascular system to changes in posture. Expected decreases in BP, MAP, CO at 30 seconds post-tilt and immediate decreases in SV and TPR as seen in Figures 2, 4, 6 and Table 1 were observed. These decreases were due to increased pooling of blood in the lower limbs leading to lower venous return and subsequently decreasing flow out of the heart. Furthermore, there was a reflexive response by the autonomic nervous system in order to regain normal cardiovascular parameters mediated by the baroreceptors.

Diabetes (Diabetes Mellitus) is an unremitting disease where in the glucose in the blood is too high. Blood glucose level, or commonly known as the ‘blood sugar level’, are normally regulated by the hormone insulin that is made by the pancreas. Diabetes takes place when a problem in the hormone happens and how the body works. There are different types of diabetes – Type 1, Type 2, Impaired Glucose Metabolism, Gestational Diabetes and the Secondary Diabetes, but the two main

Diabetes Mellitus is a group of diseases accumulating together, which will then affect how the body uses blood sugar (glucose). Glucose is the body’s energy mechanism to feed the cells and give strength to muscles and tissues. Glucose comes from the things you eat, mostly from the foods or drinks that include large amounts of sugar. “Diabetes is one of the most common diseases in the US. It is estimated that 16.7 million US adults (about 7% of the total adult US population) have diagnosed diabetes. About 1 million new cases of diabetes are diagnosed annually.” (Pittas, 2008) The main organ that is affected is the pancreas. With this disease, the levels of glucose are too low or too high, then insulin can be produced in the body. Insulin regulates

The integumentary system is one of the largest and most integral organs in the human body, encompassing many structures and playing key roles in the protection and general function of the body (Zimmermann, 2014). As with everything however; things can go wrong, failures can occur causing the system to function at a level below what is required of it. It is at this point where we must be active in our response to these faults and subsequently utilise knowledge and techniques in order to contain these failures and sustain human life.

Diabetes refers to a set of several different diseases. It is a serious health problem throughout the world and fourth leading cause of death by disease in the country. All types of diabetes result in too much sugar, or glucos in the blood. To understand why this happens it would helpful if we understand how the body usually works. When we eat, our body breaks down the food into simpler forms such as glucose. The glucose goes into the bloodstream, where it then travels to all the cells in your body. The cells use the glucose for energy. Insulin, a hormone made by the pancreas, helps move the glucose from bloodstream to the cells. The pathophysiology of diabetes mellitus further explains the concept on how this disease works. Pancreas

Hypovolemic shock is a decreased volume of blood in the circulatory system, which caused by fluid and/or blood loss (Garretson & Malberti, 2007, p. 47-48). This volume depletion in Mr Jensen’s case could have occurred as a result of his traumatic injury and surgery. As a result of the fluid and/or blood loss the body can enter into different phases of the hypovolemic shock, including initial, compensatory, progressive and refractory (Garretson & Malberti, 2007, p. 47-48). Once the loss of fluid/blood volume exceeds 750ml, a decrease in cardiac output and blood pressure occur. For this reason, the parasympathetic nervous system is mediated to shunt the blood towards the vital organs. This also explains the impaired blood circulation in Mr Jensen’s right leg that is cool to touch (Garretson & Malberti, 2007, p. 47-48). Mr Jensen’s post-operative assessment data such as blood glucose level of 17mmol/L, heart rate 107, respiratory rate 24 BPM and decreased urinary output reflect his body psychological response to stress, induced by the surgical procedure (Gordon & Craft, 2011, pp. 1047-1051). This resulted in a major trauma, which activated the metabolic stress response at the hypothalamus and sympathetic nervous system (SNS). For this reason, the adrenal gland was mediated by the SNS to release adrenaline and noradrenaline. Furthermore, the hypothalamus activated the hypothalamic-pituitary-adrenal axis to release hormones, which resulted in an increased level of cortisol,

Composed of various systems, the human body exists as a complex and sophisticated machine that carries out intricate tasks, crucial for life. The most vital of these is the circulatory system. The combination of the heart, lungs, arteries, and veins make up this highly important system. Transporting nutrients and oxygen to tissues and organs, while also discarding waste products remain the main purpose. Three separate systems, the cardiovascular, pulmonary, and systemic all work together with the sole intention of circulating blood and nutrients through the body. Through the beating of the heart, circulation to the lungs, and transportation of oxygen rich blood throughout the body, each human being has the ability to inhale and exhale effortlessly, while our body works efficiently to complete the essential task of the circulatory system. The circulatory system works in a cycle that repeats itself sixty to one hundred times a minute. A single complete heartbeat makes up one cardiac cycle (Toro).
