The aortic arch then branches into three major branches the brachiocephalic trunk (branches into right common carotid and right subclavian), the left common carotid artery, and the left subclavian artery. These three vessels provide blood to the head, neck, and upper limbs, and also part of the thorax. The descending aorta runs along the anterior spine and is called the thoracic aorta when it reaches the thorax. Later it becomes known as the abdominal aorta as it reaches the abdominal cavity. The abdominal aorta supplies the abdominal walls, viscera, and ends at T4 level where it branches into right and left common iliac arteries to supply the pelvis and lower limbs.
Anatomy and Physiology Task 1 1. Discuss your dissection of the sheep heart and the cardiovascular system of the fetal pig by doing the following: a. Describe the similarities and differences between the fetal pig heart and the sheep heart. Differences: 1. Size 2.
Next, we took the front half of the eye with the cornea and with a pair of scissors we cut off the cornea. This allowed us to locate the iris. We then flipped the front part of the eye to locate the ciliary body. After locating the ciliary body we took out the lens by pulling it out. With this done, we removed the retina, a thin tissue like material, which is located in the posterior part of the eye.
As we continue to make our way to the heart, we merge with the right external iliac vein. This is also another name for the femoral vein, and is also considered a deep vein in the lower leg. Its main responsibility is taking deoxygenated blood from the legs back to the heart. It is located right behind the inguinal ligament in the lower abdomen. The inguinal ligament support the area between the abdomen and the thigh (Inguinal Ligament, n.d.).
I also briefly touch on what an abdominal aortic aneurysm is and how to look at it with ultrasound. Abdominal Vascular Physiology The abdominal aorta is the continuation of the thoracic aorta beginning at the aortic hiatus of the diaphragm. It runs parallel to the IVC slightly to the left of the mid line. It then bifurcates at the level of the umbilicus into the right and left common iliacs. The normal diameter of the aorta is around 2 cm.
Next we made and incision to the abdominal cavity, using a scalpel to expose the internal organs. After identifying all of the organs of the fetus’ body we started to remove the organ that we used for testing. The first we removed was the heart. We removed the heart using a scalpel and weighed the heart. We then compared the weight of our pig’s heart to three other fetal pigs.
Trach in place with 40% humidified oxygen by Venturi mask. VS – AP, BP on left arm, P, SpO2 IV – PICC line (heplocked) right UE Mobility – reposition in bed x1 AOCs: Neuro Assessment Abdominal assessment Skin assessment – sacrum Respiratory management – sterile suctioning
left upper quadrant spleen superior to stomach left hypochondriac region The stomach is medial and slightly inferior to the spleen. 10. Name the structures found within the mediastinum (seen on the x-ray). heart, esophagus, trachea, thymus, and several large blood vessels that enter and exit the heart. The mediastinum (located between the lungs in the thoracic cavity) contains the heart, thymus, esophagus, trachea, and several large blood vessels.
With repeated epidodes: v. Barrel chest vi. Elevated shoulders vii. Use of accessory muscles of respiration viii. Facial appearance: flattened malar bones, circles beneath the eyes, narrow nose, prominent upper teeth 3. Discuss the pathophysiology of asthma.
First bring the horse to the grooming area and put him on the cross ties to keep him from moving. The cross ties are two clips that are connected to the wall by a rope. Once the horse is on the cross ties he is ready to be brushed. First begin with the curry comb. The curry comb is a circular brush that is used to bring up all the dirt from the horses coat.
