Answer the following question given this paragraph: Location of the Heart The human heart is located within the thoracic cavity, medially between the lungs in the space known as the mediastinum. Figure 19.2 shows the position of the heart within the thoracic cavity. Within the mediastinum, the heart is separated from the other mediastinal structures by a tough membrane known as the pericardium, or pericardial sac, and sits in its own space called the pericardial cavity. The dorsal surface of the heart lies near the bodies of the vertebrae, and its anterior surface sits deep to the sternum and costal cartilages. The great veins, the superior and inferior venae cavae, and the great arteries, the aorta and pulmonary trunk, are attached to the superior surface of the heart, called the base. The base of the heart is located at the level of the third costal cartilage, as seen in Figure 19.2. The inferior tip of the heart, the apex, lies just to the left of the sternum between the junction of the fourth and fifth ribs near their articulation with the costal cartilages. The right side of the heart is deflected anteriorly, and the left side is deflected posteriorly. It is important to remember the position and orientation of the heart when placing a stethoscope on the chest of a patient and listening for heart sounds, and also when looking at images taken from a midsagittal perspective. The slight deviation of the apex to the left is reflected in a depression in the medial surface of the inferior lobe of the left lung, called the cardiac notch. Q: The human heart is located within what cavity? Choices: - pelvic - spinal - abdominal - thoracic A:
thoracic

Ques: Answer the following question given this paragraph: Topographic maps that show water depths are called bathymetric maps . An example of one is pictured below ( Figure below ). Bathymetric maps are made of any water body, including lakes and oceans. On these maps, the contour lines represent depth below the surface. Therefore, high numbers are deeper depths and low numbers are shallow depths. Q: What are topographic maps that show water depths called? Choices: - solenoid maps - morainic maps - Water Table maps - bathymetric maps A:
Ans: bathymetric maps

Question: Answer the following question given this paragraph: The image below shows the way in which a blocked coronary artery can cause a heart attack. The loss of oxygen to the heart muscle cause that part of the tissue to die. Maybe one day, stem cell therapy will allow for the replacement of the dead cells with new cardiac muscle cells. Q: The loss of oxygen to the heart muscle causes that part of the tissue to what? Choices: - beat harder - thrive - beat erratically - die A:
Answer:
die
