Beating Heart

The Cardiac Cycle The cardiac cycle is the sequence of events that occur in the heart during one heart beat. It is how the heart operates, and what exactly happens when it contracts and relaxes. The heart is equipped with four chambers and one-way valves that work with precision to pump blood to and from the body. The heart regulates blood volume to support efficient circulation to the cells, tissues, organs, and systems. It provides oxygen and nutrients to the bodies tissue while also…

long-lasting inflammatory disease that strikes when the body’s immune system attacks its own tissues and organs. The inflammation that is caused by this disease affects multiple systems of the body- including your skin, blood cells, kidney, brain, heart and lungs. There are multiple forms and types of lupus, no two cases are the same. Studies show that lupus results from a mixture of your genetics, hormones, and climate. There are certain potential triggers such as sunlight, infections, and…

My heart thumps like a bass drum in my ears as I run. I can barely breathe but I don’t stop. I reach my car, crank the engine and put my foot to the floor. Driving through the streets of Brisbane to the highway, I start to think over Alice’s and my relationship. “You should come over this weekend. We can work on our project.” I messaged her late at night. “Okay, I’ll ask my parents.” Alice answers quickly before confirming she can. On Saturday morning, she arrives at my house. We work on our…

Effects on the Brain and Mental Health When someone is under chronic stress, it begins to negatively affect a person’s physical and mental health. Mental health problems due to stress can cause many different disorders in the body as well as the brain; they can also affect a person’s personality, thought processes as well as social interactions. Mental health disorders can occur in different forms, some symptoms may overlap, making disorders hard to diagnose. A few common disorders that can be…

weakness that begins in the legs and pelvic region in early stages (“Diseases and Conditions”, 2014). Eventually, the disease will spread to upward extremities, such as the arms, head, and chest, which then leads to breathing problems and possible heart failure (“Diseases and Conditions”, 2014). In order to treat these physiological effects, physical therapies are mainly used to help patients remain mobile as long as possible and to reduce any skeletal and joint deformities that form from the…

cardiovascular system is an integral system responsible for maintaining homeostasis in the body. It is composed of the muscular pumping organ, the heart, and a closed system of vessels called arteries, veins, and capillaries. “A baby 's heart begins to develop at conception, but is completely formed by eight weeks into the pregnancy” (Stanford Children’s Health). As the heart reaches structural and functional maturation, it will involuntarily pump blood to the blood vessels to nourish cells with…

one could see internally, the heart is pumping blood rapidly as well. This is known as the Cardiovascular System. It contains not only the heart, but also the blood vessels, blood and much more which will be further 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…

The narrowing keeps the valve from operating properly by not allowing the valve to fully open. With the aortic valve not working correctly, it causes extra stress on the valve. Since the heart has extra stress on it, the blood flow is often reduced. The blood that cannot make it through the aorta causes the heart to work harder in order to supply the body with the correct amount of blood that the…

Pigs and mammals share a number of similarities in external features. Pigs and mammals have -an umbilical cord -ears, eyes, mouth -four limbs -an anus on the exterior - a scrotal sac (male pigs) like most mammal males -hair (fur, whiskers) -teeth, tongue and two nostrils (Nose) The fetal pig does indeed have pelage and tactile. Firstly, the pelage covers most of the body such as the (dorsal, ventral, anterior, posterior etc). The pelage alsos possesses a relatively short length. Moreover,…

cancer, and diabetes. These conditions could, in fact, most likely be prevented through healthy diet and exercise. In 2007, Doctor Guy Berkenboom, professor of cardiology at the Erasme Hospital, Brussel, stated in an article in the Journal of American Heart Association, that a less aggressive approach to treating cardiovascular disease through pharmaceutical treatments and changing the patient’s lifestyle would be more beneficial and less invasive. He feels many Belgium hospitals are sending too…
