**Transcription:**5. Trace the route of a red blood cell **one full cycle** through the circulatory system. This cell is destined to enter the coronary circulation from the aorta, so that it can release its oxygen to the myocardium at the apex. Answer by drawing a linear diagram below. Use boxes and arrows of your own, starting and ending in the right atrium.---**Instruction for Diagram Creation:**To complete the diagram, consider the following steps for tracing a red blood cell as it travels through the circulatory system:1. **Right Atrium**: Start here, where deoxygenated blood enters the heart.2. **Right Ventricle**: Blood moves to the right ventricle.3. **Pulmonary Arteries**: Blood is pumped to the lungs via the pulmonary arteries.4. **Lungs**: Gas exchange occurs; blood releases CO2 and receives oxygen.5. **Pulmonary Veins**: Oxygenated blood returns to the heart through the pulmonary veins.6. **Left Atrium**: Blood enters the left atrium.7. **Left Ventricle**: Blood moves to the left ventricle.8. **Aorta**: Oxygenated blood is pumped into the aorta.9. **Coronary Circulation**: Blood enters coronary circulation to supply the heart itself.10. **Body**: The blood delivers oxygen to various tissues.11. **Veins**: Deoxygenated blood returns through veins.12. **Right Atrium**: Cycle completes as blood re-enters the right atrium.Use boxes to represent each step and arrows to indicate the flow direction. Ensure the diagram is clear and labels are concise to facilitate understanding. **3. Label these structures on the anterior view of the heart.**This section requires labeling the key structures visible on the anterior view of the heart. The diagram shows a detailed anterior view with several structures indicated by lines pointing from the heart to blank labels.Key points include major structures such as:- The aorta- The pulmonary trunk- The superior vena cava- The right atrium- The left atrium- The right ventricle- The left ventricle- Other visible structures like the coronary arteries and veins.---**4. Label the structures of the conduction system of the heart.**This diagram focuses on the heart's conduction system, which is crucial for maintaining the rhythmical beating of the heart. The image highlights the internal components of the conduction system numbered from 1 to 5.Key components of the conduction system likely include:1. The sinoatrial (SA) node2. The atrioventricular (AV) node3. The bundle of His4. The bundle branches5. The Purkinje fibersEach of these numbers corresponds to lines pointing to specific parts of the heart, which help regulate the heartbeat by conducting electrical impulses. This diagram illustrates their positions inside the heart, giving insight into how the heart's electrical system controls its pumping action.

Circulatory system is one of 12 body system that comprises of :- A ) Heart B ) Blood C ) Blood vessels Out of which , Heart is chiefly pumping organ thta is meant for sending pure blood to all body parts .( 5) Mammalian heart comprises of 4 chambers :- Right atrium , right ventricle , left atrium and left ventricle. Right side is basically concerned with taking and distribution of impure blood while left side is concerned with taking and distribution of pure blood. Linear diagram will be as :- ( 3) Heart basically consists of four chambers :- Left atrium , right atrium , left ventricle, right ventricle. a) Blood initially enter in the right atrium which is impure blood . b) From the Right atrium , blood reaches to right ventricle. c) Impure blood from right ventricle reaches lungs via pulmonary artery. d) From lungs , pure blood reaches left atrium via Pulmonary vein. Blood then enters left ventricle . e) From left ventricle , oxygen rich blood moves to all parts via Aorta. Labelling of Anterior structure of heart is as :- ( 4) Electrical impulse / signals in the heart aids in maintaining heart beat . Conducting system of heart comprises of :- I ) SA node. II ) AV node III) Bundle of His. IV) Left and right bundle branches V ) Purkinje fibres Labelling of conducting system of heart is as:-

Early defibrillation is critical for individuals with sudden cardiac arrest for the following reasons EXCEPT: O A common initial rhythm in out-of-hospital witnessed sudden cardiac arrest is ventricular fibrillation (VF).
