M1. Discuss the role of energy in the body The three systems in our body that work together are cardiovascular‚ respiratory and digestive systems which supply energy to the cells of the body. I will be describing their role of energy in the body system; also I am going to explain the physiology of the three named body systems in relation to energy metabolism. Respiratory System The respiratory system consists of tissues and organs in our body which are formed into groups. The system includes airways

Learning outcomes On completion of this unit a learner should: 1 Know the organisation of the human body 2 Understand the functioning of the body systems associated with energy metabolism 3 Understand how homeostatic mechanisms operate in the maintenance of an internal environment 4 Be able to interpret data obtained from monitoring routine activities with reference to the functioning of healthy body systems.

Anatomy and Physiology P5/M2 - Homeostasis Homeostasis is the need for an organism or a cell to regulate its internal environment (conditions within the fluid surrounding its body cells) by a system of feedback controls to stabilise health and functioning despite the outside changing conditions. This is important as this is what maintains and helps internal conditions (body temperature) to remain stable and constant. In humans homeostasis happens when the body regulates its body temperature in

requires a receptor‚ a control centre‚ and an effector. A receptor is the structure that monitors internal conditions. Receptors sense changes in function and begin the body’s homeostatic response. These receptors are connected to a control centre that studies all the information sent to it by the receptors. In most homeostatic mechanisms‚ the control centre is the brain. When the brain receives information about a change in the body’s internal conditions‚ it sends out signals along nerves. These signals

The cranial nerves that are associated with our taste sense are VII Facial located within the tongue‚ IX Glossopharyngeal located within the tongue‚ and X Vagus located within the pharynx. Taste likes and dislikes have homeostatic value. Taste is affected by many factors‚ and what is commonly referred to as our sense of taste depends on stimulation of our olfactory receptors by aromas. Smell- The nose is the body part that helps us sense smell. The nose contains thousands

Study of Oxygen Consumption to Measure Energy Metabolism in Mammals Brianne Simonsen Lab Section 8 4 Oct. 2005 Abstract In this experiment the oxygen consumption of a mouse in environments of varying temperatures was studied. The hypothesis behind this experiment was that more oxygen would be consumed at a lower temperature to maintain body heat. To measure the rate of oxygen consumption a mouse was given a specific amount of oxygen. The amount consumed in a specific time was measured and

Nancy Yedanapalli physio ex Activity 6 1. Explain why the larger waves seen on the oscilloscope represent ventricular contraction. a. The ventricular contraction is of greater force than the atrial contraction‚ since the ventricular contraction functions to send blood throughout the entire body (systemic circulation)‚ where as the contraction of the atrium send blood only to the lungs and rest of the the heart (pulmonary circulation). 2. Explain why the amplitude

Circulatory System Composition of Blood Red Cells -These are tiny‚ disc-like cells which do not have nuclei. -In their cytoplasm is the haemoglobin‚ a protein combined with iron. Haemoglobin combines with oxygen in places where there is a high concentration of oxygen‚ to form oxyhaemoglobin. -Oxyhagemoglobin is unstable compound. It breaks down and releases its oxygen in places where oxygen contentration is low. White Cells -They undergo a process of matruation and development in the

conditions is achieved by the coordination of all the organs and tissues. In the body positive‚ negative and feed-forward feedback mechanisms occur. Generally to maintain homeostasis the body uses the negative feedback mechanisms.There is a general homeostatic mechanism. It involves disruptors or stimuli‚ detectors or sensors‚ control system‚ efferent pathway and effectors. Certain disruptors produce a change in variable. The sensors sense the change. The information about the change is then sent to the

P4: Explain the role of the kidney in the homeostatic control of water balance P5: Explain dysfunction in relation to water balance and possible treatments M3: Discuss dysfunction in relation to water balance and possible treatments D2: Analyse the impact on the human body of dysfunctions in relation to water balance For P4‚ I’m going to outline the physiological overview of the kidneys and then I am going to explain the renal system. Also I am going to explain the kidneys in more detail.
