trace the path of a red blood cell through all anatomical/structural areas of the heart. The path of a RBC consist of it first beginning in the heart as the RBC transports oxygen into the aorta by the aortic valve through contracting of the left ventricle. From the aorta, the RBC then travels through an artery with the help of arterioles to reach the capillaries. When in the capillary, the oxygen molecule that is carried by the RBC then detaches and travels through the capillary into the tissues…

It was hypothesised that the ventricle of the Bufo marinus would have a greater mass (g) in comparison to the atrium. Prediction of results You predicted that: It was predicted that the ventricle has a greater mass than the atrium of the Bufo marinus. Materials and methods 2 The Bufo marinus was firstly double pithed then opened via surgical scissors and tweezers to expose the abdominal cavity. The heart was located and the connective tissue surrounding the heart was removed so the heart…

cardiovascular system. The heart has four main parts: the left ventricle,the right ventricle, the left atrium, and the right atrium. A wall of muscle called the septum separates them. Oxygen-rich blood from the lungs goes to the left atrium by the pulmonary vein. The left atrium then pumps this blood to the left ventricle. The right atrium collects deoxygenated blood from the body and then pumps this deoxygenated blood to the right ventricle. The left vertical…

Once filled, the right atrium contracts and pumps its contents into the right ventricle through the tricuspid valve. Once the right atrium is drained completely, the tricuspid valve will close to prevent blood from flowing back into the right atrium. Next, the right ventricle contracts, causing the pulmonary valve to open and forcing blood into the pulmonary artery. Once the blood is emptied, the pulmonary valve will close to…

rn what happens during the process of the Cardiac Cycle when the heart beats Post Cardiac Cycle poster and vocab on board Lesson (5 minutes) Ask students to place their right hand over their heart and to make a mental note of what they feel 1 minute Ask students have they ever wondered why they heart beats slower or more quickly during certain events? 'Lub-dub,' 'lub-dub' - This is the familiar sound of the heartbeat. You can think about the things that make your heart race, like watching a…

regularly, which then spread throughout the heart allowing it to pump. The wave of excitation is stopped by the non-conducting disc of tissue located at the bottom of the atria. It prevents the wave from causing the ventricles to contract too early. The only path to the ventricles is through another node known as the Atrioventricular Node (AV) At the AV node, the electrical pulse is delayed allowing the atria to fully contract. After this the wave then travels down the inter-ventricular wall,…

Identify or trace the path of a red blood cell through all anatomical/structural areas of the heart. • The red blood cell carrying oxygen is pushed into the aorta through the aortic valve by contraction of the left ventricle (Marieb, Mitchell, Smith, 2013, pg. 446). • From the aorta, the red blood cell travels into one of the arteries from the arterioles then will hit the capillaries (Marieb, Mitchell, Smith, 2013, pg. 446). • Within the capillary, the oxygen molecule that is taken by the red…

atrium and the right ventricle. The valve only permits the blood to flow from the atrium to the ventricle (Healthline). The pulmonary valve is at the opening from the right ventricle in the pulmonary artery trunk. “The pulmonary valve moves the blood towards the lungs and keeps it from going back into the pulmonary artery” (Healthline). The mitral valve is between the left atrium and the left ventricle. This valve consents the blood to drift from the left atrium to the left ventricle. The mitral…

the heart muscle has become too stiff. This process mainly relates to the heart muscles of the ventricle chambers. The ventricles are the main problem within heart failure, they are either too stiff or not contracting properly. The heart ventricles cannot pump hard enough during systole, which is called systolic heart failure. Diastolic heart failure is when not enough blood fills into the ventricles during…

D. PULSE PRESSURE INTRODUCTION The pulse pressure is the difference between the systolic and diastolic pressure. The systolic or top pressure is defined as the amount of pressure exerted on the blood vessels when the ventricle is contract (systole). The pressure is due to the force produced as the blood is ejected contacted with the blood vessel’s wall. On the other hand, the diastolic or bottom pressure is defined as the amount of pressure of the blood vessels when the heart is at rest…
