contraction. Your answer: 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). The contraction of the atrium send blood only to the lungs and rest of the the heart (pulmonary circulation). 2. Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation. (Hint: relate your response to the refractory period of the cardiac action

Describe patient symptoms and conditions that could cause alterations in: Cardiac Output Volume of blood flowing through systemic or pulmonary circuit expressed in liters per min Normal= 5 L/min (resting adult) HRXSV= CO Factors: preload‚ afterload‚ myocardial contractility‚ heart rate As heart rate increases‚ this allows less time for diastole and the heart often cannot fill adequately. Therefore‚ a very rapid heart will often have

Portfolio Task: Module 1 "Effective study skills are the sole foundation of a sound education". Study skills or study strategies are approaches applied to learning. They are generally critical to success in school‚ considered essential for acquiring good grades‚ and useful for learning throughout one’s life. Study skills are fundamental to academic competence. Effective study skills are associated with positive outcomes across multiple academic content areas and for diverse learners. Study

the right atria and right ventricle receives deoxygenated blood from all parts of the body and pumps this blood to the lungs for oxygenation (pulmonary circulation). The left cavity composed of the left atria and left ventricle receives the oxygenated blood from the lungs and pumps this blood to all body parts through the aorta (systemic circulation). The heart has four valves that regulate the flow of blood through its chambers. Blood flow from the right atrium to the right ventricle is regulated

Anemias commonly result from (1) impaired erythrocyte production‚ (2) blood loss (acute or chronic)‚ (3)increase erythrocyte

salvageable area. 4. Answer c. The hemorrhagic transformation of an ischemic infarct - the so-called reperfusion hemorrhage is a complex phenomenon. The three main factors associated with this include the size of the infarct‚ richness of collateral circulation‚ and the use of anticoagulants and thrombolytic agents. Interestingly hypertension is not considered to a risk factor for reperfusion

Heart: Atria - chambers that receive blood Ventricles - pump blood out Single Circulation Bony fishes‚ rays‚ sharks Heart consists of two chambers: one atrium and one ventricle The blood passes through the heart once in each complete circuit Ventricle contraction pumps blood to the gills Blood that leaves the heart in single circulation passes through two capillary beds before returning Double Circulation Amphibians‚ reptiles‚ mammals One pump from the right side delivers oxygen-poor

consists of two pairs of chambers - the atria and ventricles‚ which act as separate pumps. The right half of the heart "pumps" venous-rich carbon dioxide blood through the lungs‚ it is - a small circulation. The left half throws oxygenated blood that is passed from the lungs into the systemic circulation. Venous blood from the upper and lower hollow vein enters the right atrium which consist of the “superior vena cava” which is a smaller vein that circulates de-oxygenated blood from the upper half

capillaries that arises from a single metarteriole. In most of the body‚ blood can flow through a capillary network from an arteriole into a venule. D. How would David’s blood reservoirs respond to his low systemic blood pressure? * As blood leaves the aorta and flows through the systemic circulation‚ its pressure falls progressively as the distance from the left ventricle increases. E. How would the loss of plasma proteins affect the capillary exchange in David’s tissue? * The loss of plasma
