**Labeling Pre-Lab: Valves of the Heart****Image Description:**The image displays an anatomical model of the heart from an anterior view, showcasing its internal structures and major valves.- **Labels and Structures:** - **A**: This label points to the aortic valve, which regulates blood flow from the left ventricle into the aorta. - **B**: This label indicates the pulmonary valve, which controls blood flow from the right ventricle into the pulmonary artery. - **C**: This label identifies the tricuspid valve, situated between the right atrium and right ventricle, ensuring one-way blood flow. - **D**: This label marks the mitral valve, located between the left atrium and left ventricle, facilitating proper blood flow.**Diagrams:**The model demonstrates the heart's internal anatomy with a focus on the valves, illustrating their positions and roles in directing blood flow through the heart chambers and into major arteries. Each labeled part highlights specific valves critical for maintaining circulatory efficiency.

The anterior view can show the four chambers of the heart, some important blood vessels, valves present in the valves, and so on. The septum present between the two atria is overlapped or covered by the aorta and pulmonary trunk. The aorta is the largest artery. A- pulmonary valve: The grey-colored trunk present just above the A is the pulmonary artery. The pulmonary valve is a type of semilunar valve. This is present at the opening of the pulmonary artery. This prevents the blood flow back into the heart. The right ventricle is connected to the pulmonary artery. B- aortic valve As the name suggests this is present at the opening of the aorta. The aorta is the major artery that takes blood from the left ventricle to the different body parts. This prevents the backflow of blood into the left ventricle. C-mitral valve The Mitral valve is present between the left chambers of the heart. The valve is present between the left atrium and the ventricle. This prevents the backflow of blood into the left atrium. D- tricuspid valve This valve is present between the right chambers. This means this prevents the backflow of blood from the right ventricle to the right atrium. Since blood moves from the right atrium to the right ventricle through this valve.

You are reading a surgeon’s operative report. During the course of surgery, she made several incisions. Your job is to read her operative report and determine where the incisions were made. Draw and label the incision on the figure below. The first incision was in the right anterior sternal region, 3 centimeters inferior to the cervical region. The cut extended vertically in an inferior direction, ending 2 centimeters superior to the umbilical region. The second incision began in the left anterior, lateral inguinal region and extended horizontally in a medial direction for 4 centimeters to the pubic region. At the pubic region, the cut turned and extended vertically in a distal direction for 4 centimeters and ended in the femoral region. The third incision was made in the left posterior, lateral femoral region, 2 centimeters proximal to the popliteal region. The cut extended in a distal direction to 2 centimeters proximal to the tarsal region.
