Ventricle

the inferior vena cava! We are now in the right side of the heart, literally, the right atrium. The SA node’s action potential fires again and through the tricuspid valve we go. We’re now in the right ventricle. This one is roomy like the left so we have to wait with the AV node until the ventricle fills up some more. Finally! The AV bundle fires and we pump through the pulmonary semilunar valve into the pulmonary trunk and out the pulmonary arteries. We are on our way back to the lungs now. It…

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…

Congestive heart failure (CHF) is the condition in which the heart cannot pump blood the nutrients effectively to the body’s organs. Excessive fluid buildup is common in the lungs and/or other such organs and body parts. In many cases of congestive heart failure, the fluid builds up in the lowest part of the body such as the feet referred as pedal edema or the lower back known as sacral edema if the patient is bedridden. This swelling is caused when the heart slows and the blood begins to back…

The parts of the circulatory system include the heart which is made up of the left and right atria, the left and right ventricle, veins, arteries, capillaries, and blood. The atria take blood in and are small and non-muscular. When the valves open, blood flows into the ventricle. The ventricle pump blood and are thick and muscular. The right side of the heart collects deoxygenated blood from the body and pumps it to the lungs where the blood is oxygenated…

Report Summary: Gas Exchange Methods of analysis: Andrea used a heart rate monitor to record and compare the impact the spin class has – before, during and after- on her heart. The heart rate monitor consist of two parts they work together. The transmitter which looks like a belt and needs to be fixed around the chest and the receiver will be worn as a watch on the wrist. They have different functions, the monitor will measure and record your average heart rate from the moment the monitor is…

previous beat, causing the heart to contract earlier than expected. This arrhythmia is a very common occurrence in all ages and usually is not serious. Supraventricular tachycardia, or paroxysmal SVT or PSVT: SVToccurs when any structure above the ventricle (usually the atria or the AV node) produces a regular, rapid electrical impulse resulting in a rapid heartbeat. Sick sinus syndrome: Irregular electrical impulses generated by the SA node cause a slower-than-normal heart rate (sometimes…

upside down pear with arteries and veins branching from its upper and lower regions. On the inside, the heart is separated into four chambers. The upper two chambers are the right and left atria and the lower two chambers are the right and left ventricles.…

closer to the apex, it will converge into the anterior interventricular arteries, which are a part of the left coronary arteries. These arteries mostly run across the underside of the heart, also supplying blood to the bottom portion of the left ventricle and the posterior portion of the septum. The coronary arteries anastomose many times which allows for many routes for blood delivery. Once the blood passes through the capillary beds of the myocardium, cardiac veins then collect the venous…

Acute Kidney Injury (AKI) occurs when there is a sudden loss of renal function resulting in the bodies inability to maintain homeostasis. AKI is common in clients who are in the hospital, in intensive care units, and especially in older adults (“Acute Kidney Injury” (AKI), 2017). The following is an evolving case study regarding a client who presented to the emergency department after experiencing nausea, vomiting and diarrhea for the past week. This evolving case study will evaluate the…

ineligible for a donor heart, can have an improved quality of life with a destination therapy LVAD (Trivedi et al., 2014). . A ventricular assist device cannot be placed if there is aortic insufficiency, mitral stenosis, impaired filling of the left ventricle, or intra-cardiac shunting (Wilson, Mudge, Stewart, & Givertz 2010). However, it is possible to correct these conditions during implantation surgery. A patient may be too small to accommodate the devices if he or she has a body surface…
