Inferior vena cava

The cardiac cycle begins when the deoxygenated blood from the upper part of the body 7 and the lower body 8 enters into the hearts through the superior vena cava 9 and the inferior vena cava 10, this blood enters the right atrium 11. Now the right atrium contracts pushing the blood into the right ventricle 1 through the tricuspid valve. As the ventricle is filled the tricuspid valve closes to prevent any back flow of the…

contrast, pericarditis is when pathogens infect the pericardium and causes inflammation. 40. The right atrium receives blood from the systemic circuit from two great veins, the superior vena cava and the inferior vena cava. The coronary sinus opens into the right atrium inferior to the connection with the superior vena cava. 41. ADH is released at the posterior lobe of the pituitary glands. It causes a peripheral vasoconstriction that elevates blood. This hormone stimulates water conservation…

IVC Filters May Have Deadly Complications Inferior vena cava filters, or IVC filters, are implanted in individuals who cannot safely take blood thinners in order to prevent clots from traveling to the lungs. These filters are designed to catch any clots and allow them time to safely dissipate. The FDA has received many reports of complications from retrievable IVC filters. The filters have punctured organs, migrated to other parts of the body, and fractured. As a result, the FDA has issued…

Fetal circulation differs greatly from that of a newborn heart. Although, outwardly appearances may seem similar. By taking an internal look we may be able to distinguish four adaptations that fetal hearts undergo while in utero. First, we must understand that the fetus receives all blood and nutrients from the parental placenta. The fetus receives this blood from the placenta through the umbilical vein. This is the first adaptation that we see in the fetal cardiovascular circulatory system.…

Q-1. Describe the function of hemoglobin in blood and describe how pH can affect the function of hemoglobin and the amount of oxygen in blood. Be sure to relate the lab results you obtained to this discussion. Hemoglobin’s main function is to carry oxygen throughout the human body. As the oxygen molecule is dissolved in the blood it combines with hemoglobin forming oxyhemoglobin. Oxygen released from oxyhemoglobin increases as the blood pH levels decreases. Deoxyhemoglobin can also bind to the…

the left and right atrium are the one receiving the blood meanwhile the lower chambers, the left and right ventricle, are the one that pumps the blood our of our heart as the heart contracted. On the right atrium, there is a part called superior vena cava that helps to bring the poor oxygenated blood form the upper part of our body as it travels to the right atrium. Then, from the lungs there are pulmonary veins that brings poor oxygenated blood to left atrium. Also our heart composed of valve…

Introduction of Patient My patient is Freda Wilson, a 64-year-old Caucasian female who resides in Shawnee, Kansas with her husband. Mrs. Wilson is 5’5” tall and weighs 148 pounds, has two adult children, and is a relatively healthy individual. Mrs. Wilson and her husband spent five days in Oklahoma babysitting their grandchildren, two boys – one and three years old. Within 24 hours of returning home, Mrs. Wilson had a headache, felt fatigue, and later in the afternoon spiked a fever in excess…

The insertion site of the needle is 1 cm inferior and 1 cm lateral to the junction of the middle and medial thirds of the clavicle. The needle is advanced toward the tip of the contralateral index finger, which is placed in the suprasternal notch. The direction of the needle is now aligned with the central axis of the SCV, minimizing the risk of puncturing the subclavian artery, pleura, or apex of the lung [46]. By keeping the needle in a horizontal plane, the risk of arterial or pleural injury…

explained in greater detail. The venous system takes blood back to the heart. It flows from the capillaries to the veins. The biggest vein in the body is the inferior vena cava. The superior cava carries blood from the upper part of the body to the heart, however the inferior cava carries blood from the lower part. Venous blood is very dark and both cavas ends in the right atrium. The main job of this system is to transport materials within…

sections inside: left and right atria and left and right ventricle. The right atrium receives blood that is low on oxygen molecules from the superior and inferior vena cavae. The superior vena cava is one of the largest veins in the body that brings de-oxygenated blood from the lower part of the body to the right atrium. The inferior vena cava is the other largest vein in the body that brings blood into the right atrium from the top of the upper parts of your body. The right atrium pumps blood…
