The oxygenated blood comes from placenta to the fetus through umbilical vein to the fetus’s liver. Then it moves through ductus venosus. This allows some of the blood to go to the liver. But most of this highly oxygenated blood flow to the inferior vena cava and then into the right atrium of the heart. Most of the blood flow across to the left atrium through the foramen ovale.
Thoracic kyphosis (20-400), 3. Lumbar lordosis (30-500) and 4. Sacral kyphosis (not more than 400). ANATOMICAL PLANES: Coronal or frontal plane: It is a vertical imaginary line which divides the vertebral bodies into the front and back sections. The coronal plane of the spine delineates the scoliosis of spine.
The pericardium- It has two layers. (i) An outer layer which contains a fibrous covering that wraps around the heart and holds it in place. (ii) An inner layer which has special fluid to lubricate the heart preventing friction from occurring. 2. The myocardium- this contains a strong layer of cardiac muscle
Most cystic lesions of the major salivary gland are cystic neoplasms. Benign cysts are epithelial lined cavities usually containing fluid or semisolid material, incidence is 2-5%. Benign cysts of the salivary gland are classified into three types: a) Lymphoepithelial cysts b) Salivary duct cysts c) Dysgenetic cysts a) Lymphoepithelial cyst Bernier and Bhaskar introduced the term lymphoepithelial cysts to stress that it is not an embryologic remnant. Lymphoepithelial cysts are considered distinct entities from the lymphoepithelial lesions.  Usually there is a well circumscribed, asymptomatic mass in the superficial portion of the gland.
The walls of veins are far thinner and the lumen passage much larger. The walls are not muscular and blood is pushed through the vessels by the action of skeletal muscles. Veins carry deoxygenated blood (dark red) to the heart, except for the pulmonary veins which carry oxygenated blood. Blood pressure is very low in the veins, so there are valves in the endothelial layer which prevent the back flow of blood (Tucker, 2015). The structure of capillaries Capillaries are the smallest blood vessels in the body.
Perfusion : Perfusion is the process of a body delivering blood to a capillary bed in itsbiological tissue. The word is derived from the French verb "perfuser" meaning to "pour over or through". Tests verifying that adequate perfusion exists are a part of a patient's assessment process that are performed by medical or emergency personnel. The most common methods include evaluating a body's skin color, temperature, condition and capillary refill. Perfusionists employ artificial blood pumps to propel open-heart surgery patients' blood through their body tissue, replacing the function of the heart while the cardiac surgeon operates.
The phenomenon of vein pulsation The venous retinal pulsation is occurring due to the blood pressure difference in the central retinal vein. The pressure difference occurs due to the condition of the systole and diastole pressure. The following are experimental studies carried out so far on physician experiment set-ups and existing theoretical models considered, wave surface with the Pulsations phenomena of collapsible vessels in the body deal. Few of these models are based on the anatomical and physiological conditions of the CRV, which is why most only the effect must be interpreted. Theoretical models Model according to DN Levine The theoretical model by Levine relates the phenomenon of pulsating Vein on the observed pulsations of the CRV.
Hind brain (Rhombincephalan) the hind brain contain the brain stem and the medulla oblongata (Myelencephalon) form by the anterior thickening of basal plate and posterior alar plate separated by sulcus in the fourth ventricle. The hind brain continues to form the spinal cord. As like cerebrum, cerebellum has fissured mass in the posterior cranial fossa attached with brain stem by three pairs of peduncles. From the base of the brain stem the 12 pairs of cranial nerves are arising. The motor nuclei of the IX, X, XI and XII cranial nerves line in the fourth ventricle is formed by the basal plate neurons.
shunt for oxygenated placental blood to bypass the liver), ductus arteriosus (i.e. shunt for oxygenated blood to bypass non-functioning amniotic fluid-filled lungs) and foramen ovale (i.e. passage for oxygenated blood to go from right atrium to the left
INTRODUCTION Phonocardiogram is a physiological signal that results from the vibrations created by closure of heart valves and it represents the recording of the heart sound signal. A normal cardiac cycle is comprised of two major sounds- first sound (S1) and the second heart sound (S2). The first heart sound has four components in it, due to the closure of AV and semilunar valves. The second heart sound has two components, one due to closure of aortic valve and another due to closure of pulmonary valve (Rangayyan, R.M and Lehner ,R.J (1988). In some case a third heart sound (S3) may be heard, which is corresponding to sudden termination of the ventricular rapid filling phase.
