How things flow through the heart: • blood drains into the right atrium through the superior vena cava‚ inferior vena cava‚ and the coronary sinus (drains the heart muscle itself)→Right Ventricle→pulmonary semilunar valves→lungs→pulmonary veins→left atrium→bicuspid valve→left ventricle→aortic semilunar valve→systemic circuit. What the valves do: • Prevent backflow into the atria and ventricles‚ ensuring that blood only flows one way through the heart. what vessels bring blood to the heart and

The Endocrine system helps to maintain homeostasis by secreting hormones into the bloodstream‚ which travels throughout the body. This system regulates activities such as growth and development and influence emotions and behavior. The relationship of this system alongside the other body systems is how the body maintain a stable equilibrium‚ regulating the activity of the organ systems. Nervous - The endocrine system acts as a communication tool within the human body‚ working alongside with the nervous

Pulse rate During the practical while at rest the pulse is at a normal speed as the person is not doing any activity which requires lots of energy. This changes when the person starts to exercise as the line on the graph increases‚ this shows that the pulse rate is increasing because the heart is beating faster to make sure enough oxygen reaches the cells‚ this also causes the breathing to increase as the body has to take in more oxygen to supply the body and remove the carbon dioxide.

Running Head: Sepsis 1 Sepsis: A Clinical Case Study Example Conestoga College Running Head: Sepsis 2 Abstract Sepsis is an inflammatory systemic response to infection. The symptoms are produced by the host’s defense systems rather than by the invading pathogens (Schouten et al.‚ 2008). Sepsis is a frequent cause of admission to intensive care units (ICUs) and it is one of the leading causes of death among hospitalized patients (Alberti et al.‚ 2003). It is a public health
