    Section A – Part II Cardiac cycle or heartbeat Blood enters and fills both atriums at the same time. When full the pressure causes the tricuspid and bicuspid valves to open and flows into the ventricles. Contraction (systole) of each atrium now forces any remaining blood into the ventricles. The ventricles now contract (systole) and atriums relax (diastole). The pressure closes the tricuspid and bicuspid valves (causes the first sound of the heart beat). The contraction of the ventricles opens

    blood flows across one of the heart (valves, cardiac chambers) and or vessels close to the heart Heart murmurs are classified by the intensity of the sound heard: Stage I (murmur is of low intensity and can hardly be heard) to Stage VI (murmur is extremely loud). Cardiac murmurs can be present at birth (congenital; often caused by malformations) or acquired and manifests later in the animals life. (Ex: disease of the cardiac muscles, disease of the cardiac valves, etc.). It is important to note that

    The organs are made up of tissues working together, such as the smooth/cardiac muscle tissues and blood. The tissues are made up of different types of cells working together, such as red and white blood cells, along with smooth/cardiac muscle cells. Therefore it can be concluded that the circulatory system is composed of groups of cells. All of the other organ systems throughout the body are also made

    Muscular dystrophy is a group of muscle diseases that weaken the musculoskeletal system and hamper locomotion. Muscular dystrophies are characterized by progressive skeletal muscle weakness, defects in muscle proteins, and the death of muscle cells and tissue. In the 1860s, descriptions of boys who grew progressively weaker, lost the ability to walk, and died at an early age became more prominent in medical journals. In the following decade, French neurologist Guillaume Duchenne gave a comprehensive

    The Musculoskeletal System The Musculoskeletal system is made up of muscle, bones, tendons, cartilage, ligaments, nerves and other connective tissues. The main purpose is to support and stabilise the body. The bones work together with the muscles to allow controlled movement and to keep the body’s shape. The bones of the body provide five main functions they are to produce blood cells (white and red), protect body organs (brain, lungs), provided leverage and movement (so we can sit up), and store

    Adipose is a loose connective tissue that makes up the spaces in between our organs and tissues which provides structural and metabolic support. The main role of adipose is to store energy in the form of lipids. However it also serves as cushions and insulates the body. Adipose tissue – more particularly, the brown adipose tissue – was first identified by Swiss naturalist Conrad Gessner in 1551. When Conrad Gessner first discovered the tissue he described it as it was “neither fat, nor flesh – but

    Your heart is a pump. It's a solid organ about the measure of your clench hand, arranged marginally left of focus in your trunk. Your heart is partitioned into the privilege and the left side. The division shields oxygen-rich blood from blending with oxygen-poor blood. Oxygen-poor blood comes back to the heart subsequent to coursing through your body. The correct side of the heart, including the correct chamber and ventricle, gathers and pumps blood to the lungs through the pneumonic conduits.

    Weight gain is an increase in body weight. This can be either an increase in muscle mass, fat deposits, or excess fluids such as water. Description Muscle gain or weight gain can occur as a result of exercise or bodybuilding, in which muscle size is increased through strength training. If enough weight is gained by way of increased body fat deposits, one may become overweight, generally defined as having more body fat (adipose tissue) than is optimally healthy. Weight gainer have a latency period

    bones and muscles. According to (Muscolino, 2011) the skeletal system consists of bones and provides a strong framework for the body. The muscle system is made of a group of skeletal muscle tissue that are attached to bone. This essay will discuss how the muscle and skeletal system work together. The aspects that will be explained are movement, protection and the differences. The muscle and skeletal system work together to produce movement. An example of movement is the bones and muscles in the arm

    A human’s body may appear to be a simple form, but nonetheless it is complex with trillions of living organisms working together to keep the individual alive and moving. Many of the composites that keep the individual movements are the cartilages, bones, and joints. Cartilage is divided into three classifications with the same function, but with their own specific functions as well. Bones, which protect the internal organs, are in many different categories based on the appearance of the bones.

    quantities of myelinated axons. Myelin is a fatty substance that envelops axons constructing a sheath that acts as an insulator for the electrical impulses that travel through the axon and appears as a white colour. Grey matter is associated with muscle control, some senses such as sight, and other abilities for instance restraint (Kolb and Whishaw, 1990). The other type of nervous tissue found in the CNS is white matter that is differentiated from gray matter by the relatively fewer cell bodies

    Fibroblast The fibroblast is the large cell type of the dermis. These cells are responcible for the formation of procollagen and elastic fibers. Procollagen is terminally cleaved by proteolytic enzymes into collagen which aggregates and turned into cross-linked. These tightly cross-linked collagen fibers allow tensile strength and resistance to shear and other mechanical forces.(9,10) Collagen makes up 70% of the weight of the dermis, primarily Type I (85% of the total collagen) and Type III (15%

    more they rely on their trunk and upper body for compulsion and also for stability and balance. The lower limbs still do most of the work, since the muscles of the lower limb give greater response and joints giving a greater range of motion. Three major joints of the lower extremity as well as the pelvis work hand in hand as the propulsion and muscles move the body forward. How much the body’s center of gravity moves while propelling forward defines efficiency. The gait cycle is pattern that is repeated

    Introduction Physical activity, specifically aerobic exercise, increases hippocampal and medial temporal lobe volumes, so these parts of the brain in higher-fit adults are significantly larger. This could imply that exercise is a stimulus to hippocampal plasticity.3,4 Plasticity refers to modification of neural tissue of the living brain and nervous system in response to experience and injury. These changes in the brains of aerobically trained subjects are bigger, and they demonstrate considerably

    It is an elongated muscle which allows for slow and regular contractions. The nuclei of the smooth muscle cells are centrally located and elongated, similarly to the shape of the cell. In pulmonary blood vessels and the bronchus, this muscle is used to maintain the shape and rigidity of the structure, which it does so involuntarily. The function of the pulmonary vein is the opposite

    What are tonsils? The tonsils are tissue masses that are found at the point where the mouth and throat meet. There is one tonsil on each side of the throat. The tonsils are part of the human immune system. The immune system is what helps to fight off germs that can cause a variety of illnesses. They are there to process germs and help the body recognize different types of germs so that they can be fought off. Will my child 's immune system be weaker if the tonsils are removed?

    By the time a human reaches adulthood, the skeletal system is made up of 206 bones. It also includes all the tendons, cartilages and the networks of ligaments that help to connect them. This system plays a major role in many body functions like movement, protection, support and stability, blood cell production and calcium storage – that enable us to live. One of the many groups of bones is called phalanges, the bones found in human fingers. It comes from the Latin word “phalanx” meaning “a compact

    Plantar Fasciitis Overview The plantar fascia is a band of much like a tendon tissue that starts at the heel and goes through the entire sole of the foot, clinging to the base of the finger bones. The plantar fascia form a sort of buffer and has the function to support the foot, incurvandolo. If the band is too short, the arc is more pronounced, while, if it is too long, the arc is low, and therefore it has the so-called flat foot. The plantar fascia, in the heel, is covered by a fat pad which helps
