1. Auscultation method is more accurate by using the stethoscope to listen for systolic blood pressure compared to palpation of systolic blood pressure at wrist. It is easier to listen for the ‘tap’ during the systolic pressure rather than palpating for it, as the systolic pressure may not be palpated if it is a weak pulse. 2. Systolic pressure: • Pressure in the arteries when the blood is being pumped out of the heart into the arteries • The maximum blood pressure, when the ventricles are in…

Furthermore, the more we exercise changes would occur in our cardiovascular system. When performing exercise, your muscles would need sufficient amount of oxygen and nutrients so that you can perform well. Also, the carbon dioxide produced should be released from the body. It is the main role of the heart to pump harder and faster when exercising so that oxygen is taken in and carbon dioxide is released as a by-product. There are many acute changes that occur in this system before, during and…

The automatic response of the body is to increase cardiovascular output when activity rate increases; in order to raise oxygen levels in the blood for cell respiration. However, this response is varied depending on the type of activity being undertaken by muscles. A higher intensity exercise such as running causes a larger cardiovascular response however in the increase in mean arterial pressure is small. Whereas a lower intensity exercise causes a low cardiovascular response but the increase in…

Body systems and the bond types of Vitamins and Minerals go hand in hand. The Digestive System breaks down food into vitamins and minerals to be transported to other body systems. The Integumentary System is made up of skin, which uses copper to create Melanin to help protect against the sun. The Integumentary System also uses Vitamins A and C, as well as Niacin and Zinc for healthy growth and repair of skin. The Respiratory System consists of mouth, nose and lungs to inhale oxygen and exhale…

Unit 2 The physiology of fitness P1 P2 M1 In this assignment I have been asked to talk about the physiology of fitness, because I am on am football so it is important for me to understand this side of the game. In P1 it is all about how the musculoskeletal and energy system responses to acute exercise. P2 is about the cardiovascular and repertory system and how that responds to acute exercise. M1 wants me to explain the response for the musculoskeletal, cardiovascular and repertory system to…

During exercise or human movement, a person’s heart rate, the number of beats per minute, and also systolic blood pressure increases as the intensity of the exercise increases. While diastolic blood pressure will remain the same with the exception of a 10-mmHg gap change. A typical person’s blood pressure remains around 120/80 millimeters of mercury (mmHg). It may not be the exact numbers but it is very similar to the standard. During a type of exercise a person’s systolic blood pressure, “the…

Worksheet 1: Biological Hierarchy; and Organising the Natural World 1. Define what is meant by the “biological hierarchy”. Biological hierarchy is the structured organisation of all biological entities. It can be shown in pyramid form with the most simple element at the base being atoms and at the pinnacle is the ecosphere, the most complex. 2. What is an “emergent property?” An emergent property is when a new property develops on the next step in the biological hierarchy as the levels…

The human heart contains a specialized conduction system through which it can create and transmit electrical impulses without any external neural input. The main components of the conduction system of the heart include the SA node, AV node, Bundle of His and the Purkinje fibers. The sinoatrial node (also known as SA node) is a natural pacemaker and is responsible for depolarization of the right and left atrium. This produces a P wave on the EKG reading which is normally 0.1 second and its normal…

The scientific term which is used to describe the temperature control in the body is called hypothalamus. Hypothalamus begins in your brain since your brain makes the choices for your body. This is very important because if you're too cold you can start shivering for long periods of time which can lead up to hypothermia. On the other hand, if you are too hot you and start to sweat a lot it can lead up to avoid disease. Here are the 3 different that your body can make in these tough situations.…

Blood pressure is defined as a measurement of the force with which blood presses against the wall of a blood vessel. Blood pressure, as popularly used, is the pressure determined indirectly, existing in the large arteries at the height of the pulse wave. When a blood pressure reading is taken, the systolic over diastolic value is determined. Systolic pressure is defined as an aspect of a blood pressure reading which indicates the maximum arterial pressure occurring during contraction of the left…
