Mammalian kidney investigation

Part A Independent VariableThe position in which the kidney is longitudinally cut with the scapel. These structures enable the blood or any other materials to continuously move around each other Mammalian kidney investigation to collect filtrate from the glomerulus, passing it on to the rest of the nephrons.

According to diagram 3, many circular structures that are most likely the glomerulus, which are a tangled cluster of blood capillaries. Dependent Variable The structure that can be observed from the microscope. Note any other structures attached to the kidneys and include these in the diagram.

It was evident that at all layers of the kidney, the colours are different. Need essay sample on Mammalian Kidney Investigation? Part B Independent VariableThe prepared slide and the region of that slide of the kidney used.

The renal cortex forms a shell around the medulla. The bases of the renal pyramids are directed towards the convex surface of the kidney.

Mammalian kidney investigation the dimensions of the kidney with a ruler and add them to the diagram of the shape of the kidney.

Mammalian Kidney Investigation

In a human body, the kidneys process about quarts of blood to sift out about 2 quarts of waste products and extra water everyday. Similar to the limitation mentioned above, in order to improve this, microscopic analysis of the kidney of other mammals should be carried out for example a kidney Mammalian kidney investigation a dog or pig.

The renal cortex of the kidney, which is labeled in diagram 2 the interior of the kidneywas almost a brownish shade of red whereas the next layer closer to the centre of the kidney; the renal medulla was a much deeper shade of red.

The kidney examine in this experiment is a kidney of a sheep. The renal artery carries the blood into the kidney and the renal vein carries the blood away from the kidney.

The granular appearance of the cortex is due to the random arrangement of tiny tubules associated with nephrons, the functional units of the kidney. Only one binocular microscope will be used in this part of the experiment. Set up the binocular microscope.

Put on the apron and disposable gloves. The outside of the kidney was dark red in colour. The tissues dip into the medulla between the adjacent renal pyramids to Mammalian kidney investigation renal columns.

Obtain the prepared slide of the kidney and put it under the microscope. The longitudinal section of the cortex of the kidney, which was microscopically observed, was drawn in diagram 3.

For example, as excretion is the process by which waste products and other non- useful materials are eliminated from an organism; the blood vessels assist with the transport of waste to the kidney to be excreted.

Wrap the dissecting board with the newspaper first then the paper towel on top of the newspaper. The most internal layer of the kidney, the pelvis was connected to the ureter. Starting from the low power, examine the slide of the kidney while trying to identify all structures.

Also, the tubular structures observed under the microscope enables the blood or any other materials to continuously move around each other and to collect filtrate from the glomerulus, passing it on to the rest of the nephrons. The substance of the kidney is divided into two distinct regions: Part B Controlled VariableMethod to control the variable The type of microscope used in this experiment.

To investigate the macroscopic appearance the structure of the mammalian kidney in respect to its function of excretion and osmoregulation. The function as two main functions- excretion and osmoregulation. One kidney is located below the spleen on the left side of the body, whereas the other kidney is located just below the liver.

The kidneys are dark red bean -shaped organs that are a very important pair of organs that perform many functions. The functions of the kidney, excretion and osmoregulation require a sufficient amount of blood vessels.

Kidneys also produce various hormones. Similarly, another limitation in this experiment is that only one type of mammalian kidney slide- a human kidney slide was investigated microscopically in this experiment.Mammalian Kidney Investigation Background Information: The kidneys are dark red bean -shaped organs that are a very important pair of organs that perform many functions.

The kidneys have a convex side and a concave side. Mammalian Kidney Investigation Background Information: The kidneys are dark red bean -shaped organs that are a very important pair of organs that perform many functions.

Perform a first hand investigation of the structure of a mammalian kidney by from BIO at Cabramatta High School. Mammalian Kidney Investigation Background Information: The kidneys are dark red bean -shaped organs that are a very important pair of.

Perform a first-hand investigation of the structure of a mammalian kidney by dissection, use of a model or visual resource and identify the regions involved in the excretion of waste products -Remove fat from Kidney and seperate tubes. Free Essay: Mammalian Kidney Investigation Background Information: The kidneys are dark red bean -shaped organs that are a very important pair of organs that.
