Baroreceptors are mechanoreceptors that detect changes in the blood pressure. It helps in maintaining the total peripheral resistance via the autonomic nervous system. The cardiac output is also maintained via the baroreceptors at a normal range. Baroreceptors are of two types - high pressure arterial baroreceptors and the low pressure volume receptors. The stretching of the vessel walls stimulate both the types of baroreceptors. In the carotid sinuses, arterial baroreceptors are present as well as in the aortic arch. The second type of baroreceptors are present in all the chambers of the heart - atria and ventricles and in the pulmonary vasculatures. Therefore, Respond to changes in the EKG - false - it refers to the electrical signals of the heart. Baroreceptors responds to changes in pressure and not electrical signals. Reacts to changes in blood pressure - true - Changes in blood pressure affect the elasticity and stretching of the vessels. Baroreceptors are sensitive to these changes. Are located in the SA node - false - As mentioned in the paragraph above, these mechanoreceptors are only found in the chambers of the heart, carotid sinuses and the aortic arch. Are located in the carotid and aorta - true

You are learning to read electrocardiograms. You know that the patient you are examining has a pathology affecting the depolarization of his ventricles, therefore you're looking for a change in what portion of his EKG? The P wave O The T wave O The QRS complex "The P wave" or "The T wave" but not "The QRS complex". None of these would be altered
What is happening during the phase labeled with the arrow? Atrial depolarization Ventricular depolarization Ventricular repolarization or AV valve closure
Can you help me with questions 21 and 22
Sympathetic stimulation increases the phosphorylation of the Ca2+ATPase in the sarcoplasmic reticulum. What effect does this have on cardiac function? It increases the rate of diastole It decreases the stretch of the ventricles The rate of systole decreases
Choose all the statements that are correct. When the heart beats, first the right side of the heart contracts, and then the left side of the heart contracts. That is one heartbeat. The sympathetic nervous system speeds up the heart rate and the parasympathetic system slows down heart rate. M Bradycardia is when the heart beats faster than normal. The SA node is the pacemaker of the heart. Coronary arteries deliver blood to the muscle of the heart. A heart attack is a myocardial infarction. The ECG (EKG) has a QRS wave that represents ventricular depolarization (the message to tell the ventricle to contract. The heart needs nerve stimulation in order to contract.
A person showing signs and symptoms of a heart attack will often: Panic and faint Deny that they are having a heart attack Take a nap to relieve pain None of the above
