1. Sketch a section of the thyroid gland and detail several thyroid follicles. 2. Draw and label a simple line sketch of the arteries from the heart to the right axilla. 3. Draw and label an example of a normal ECG recording for one cardiac cycle.

2) Insert increase or decrease into each of the sentences below which are concerned with blood pressure regulatory mechanisms that result in a decrease in blood pressure. • A decrease in blood pressure causes a(n) in nerve impulses from the baroreceptors to the Cardiovascular Control Centre ● • This increases the sympathetic nervous system input to the heart resulting in a(n) in heart rate. Sympathetic nervous system input to the blood vessels s causing vasoconstriction of both the arterial and venous side of the circulation. • The blood pressure is therefore normal level. ed to a

45. True or false. The QRS complex correlates with ventricular depolarization. 46. True or false. The T wave correlates with ventricular depolarization. 47. True or false. Blood pressure increases with increased resistance of blood flow. 48. True or false. The main objective of blood flow is to drop off oxygen to the rest of the body and pick up carbon dioxide to throw out.

Predict Three basic ways that cardiac function could be impaired

1. Discuss the major sources of blood supply to the heart and their clinical applications. 2. Describe the tunics of blood vessels. 3. Briefly, describe the fibrous skeleton of the heart. 4. Describe the various cellular elements in the blood and briefly cite their functions. 5. What are the different types of blood groups you know? 6. Describe the developmental anatomy of the human heart and its clinical implications.

7. An 84-year-old man is brought to the emergency department 30 minutes after an episode of syncope. Transthoracic echocardiography shows a 4-cm myxoma occupying the majority of the left atrium. The tumor will be excised using a robotically assisted operation via an oblique right atriotomy and transection of the interatrial septum. When making the incision into the left atrium to remove the myxoma, which of the following regions of the interatrial septum should be avoided in order to prevent injury to the cardiac conduction system? A) Crista terminalis B) Fossa ovalis region C) Posteroinferior region above the opening of the coronary sinus D) Superoanterior region above the limbus of the fossa ovalis E) Superoposterior region posterior to the fossa ovalis

Discuss  in details about the importance  of regulating  blood pressure.

3. Evaluate the following statements as true or false T/F T/F T/F T/F T/F Jet lesions are most common in the left ventricle The tricuspid is situated between the left atrium and left ventricle The endocardial layer is thickest in the atria Systole is when semilunar valves close to prevent blood backflow into the heart The sinoatrial and atrioventricular nodes are similar histologically

A client sustained a crushing injury to his right arm during a car accident. He arrives to the emergency room complaining of numbness in his right hand. He has no other injuries. What should the nurse do first? Assess the right pedal pulse Administer pain medication Call the provider D. Assess the right radial pulse
