1.6 Blood Pressure Blood pressure is the main factor in sustaining blood flow through tissues. The force applied to the arterial walls as the heart pumps blood throughout the circulatory system defines the physiological meaning of blood pressure (Bojanov‚ 2009). Blood pressure is determined by the force‚ heartbeat rate‚ and resistance to blood flow through vessels. Cyclic changes in arterial blood pressure are partially attributed to the rhythmic contractions in the left ventricle (Iaizzo‚ 2009)

(a) Give generalized conclusions (in point form) according to your observation in (a). 1. systolic pressure increases when the degree of exercise increases Systolic pressure increases gradually from 115 mmHg at rest to 150 mmHg during severe exercise. When thr degree of exercise increases‚ the skeleton muscle needs more energy(ATP) for rapid contraction by carrying out aerobic respiration. The skeleton muscle required faster uptake of oxygen and removal of carbon dioxide. At the same time‚ skeleton

Assessing Blood Pressure Anatomy of the Heart The heart is located in the thoracic cavity between the lungs within the mediastinum. It is a hollow‚ cone-shaped‚ muscular organ about the size of a fist. Functions of the Heart keeps O2-poor blood separate from O2-rich blood; keeps the blood flowing in one direction—blood flows away from and then back to the heart in each circuit; creates blood pressure‚ which moves the blood through the circuits; Regulates the blood supply based on

placement‚ I encountered an obese elderly man with type 2 diabetes who was bed bound. His BP was 98/73 so I decided to do a manual blood pressure (BP) to make sure it was not a mechanical error from the automatic machine and recorded 99/75. His other vital signs were in between the flags. I asked my patient how he was feeling‚ he said he felt fine. I told him his blood pressure was a bit low and if this was normal for him. He said it has been low a bit recently. I asked him if he could have a glass of

it pumps blood round the body to give it the energy and oxygen it needs. As the blood moves‚ it pushes against the sides of the blood vessels. The strength of this pushing is your blood pressure. If the blood pressure is too high‚ it puts extra strain on your arteries (and your heart) and this may lead to heart attacks and strokes. Having high blood pressure (hypertension) is not usually something that you feel or notice. It does not tend to produce obvious signs or symptoms. The only way to know

The things that count account for this difference between systolic pressure when the sound began‚ the stethoscope user heard it‚ and the computer operator pressed the event marker keystroke is because how fast sound travels. This comes into play because first the person using the stethoscope uses it‚ and he/she is not going to be able to react immediately to inform the computer user. There is a delay when the stethoscope user hears it from when the first sound begins‚ and then there is a delay when

Hormones can react to increase blood pressure when it becomes low‚ the sympathetic division of the autonomic nervous system uses several ways to temporarily increase blood pressure when it has dropped for example during the fight or flight response. During the response‚ the sympathetic division is needed to stimulate the adrenal glands to release the hormones epinephrine and norepineprine which stimulate the heart to beat faster and for blood to flow more forcefully‚ this effect makes most of the
