“The medulla is further divided into numerous sections called the medullary pyramids.”This region is known as the pelvis of the kidney. The medullary pyramids have urine dripping into the pelvis. The branches of the emerging arterioles of the renal artery usually go along the border found between the medulla and cortex. The smaller branches given off at right angles provided million or more of nephrons into the cortex of the kidney. Structure and function of nephrons/kidney tubules “Nephron is the basic structural and functional unit of the kidney.” The nephron consists of a tubule closed at one end, the other and opening into a collecting tubule.
Alcohol and Caffeine vs. Daphnia heart rate Abstract This experiment was performed to observe the effects of alcohol and caffeine on the heart rate of a Daphnia magna. There was a control group used along with the alcohol and caffeine to make sure we got accurate results. It was predicted that the increasing concentrations of alcohol would decrease heart rate and the increasing concentrations of caffeine would increase heart rate, based on pervious experiments. The results of this experiment proved the predictions to be valid and helped to make educated decisions about the effects of alcohol and caffeine in any living organism. Introduction Caffeine is a stimulant and diuretic.
P4: Explain the physiology of two named body systems in relation to energy metabolism in the body. Cardiovascular System This system transports materials to the liver and body cells through the bloodstream that is pumped by the heart. Blood Blood is a liquid tissue made up of; plasma, platelets, white and red blood cells and is necessary for every part of the body. The blood contains many different materials and cells and there is fluid called plasma which contains many substances dissolved in it. Plasma carries food from the stomach to cells but carries waste from the cells to the kidneys and intestine.
Unit 4222-679 Diabetes Awareness Outcome 1 1. Diabetes is a metabolic disorder. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies. 2.
It’s the most common tissue in the body. Areolar connective tissue had no obvious structure, it is made of cells and extra cellular matrix. This binds all of the layers together in the stomach, so it doesn’t fall apart. The Skin- The skin is the largest organ in the body, with a total area of about 20 square feet. The skin protects us from
Organelles include mitochondria, Iysosomes, the Golgi apparatus and the endoplasmic reticulum. Mitochondria: Every cell in the body has at least 1000 of these rod-shaped, spherical bodies and very energetic active cells like muscle and liver cells will have much more. Mitochondria are concerned with energy release. Each mitochondria has a double layered membrane but the inner layer is folded at intervals, which produces a series of ridges known as cristae. The enzymes responsible for the end stages of glucose oxidation are located on the cristae.
| Pancreas is able to produce the right chemicals at the right times in the right quantities in order to properly digest the food we eat. | Kidneys | Paired organs in the abdomen. | They prodouce urine. | Bladder | Near the pelvis | It stores urine | Uterus | In abdomen | They pass urine from the bladder to urethra | Ovaries | In the pelvis | They produced eggs (ovaries and hormones. | Liver | The liver is the second largest organ in the human body (after the skin) and the largest gland | It is located on the right side of the abdomen (to the right of the stomach) behind the lower ribs and below the lungs.
This assignment will evaluate the importance of homeostasis in maintaining a healthy functioning of the body. If homeostasis did not work properly in the body then there are many problems that could arise. Diabetes is one of those problems: Diabetes Diabetes is “a permanent change in your internal chemistry that results having too much glucose in your blood” because the body cannot use it properly. (Rudy, 1999, Page 10) Glucose comes from digesting carbohydrates and is also produced by the liver, carbohydrate comes from many different kinds of foods and drink, such as Wholegrain cereals such as Weetabix and Shredded Wheat, Brown rice, Pasta and Potatoes. “Diabetes can be tackled in different ways- by insulin and diet” (Rudy, 1999, page 19) Diet, when someone had diabetes it is best for their health to cut right down on the unhealthy foods, and stick to the health foods, this is due to the effectiveness of the medication you are on.
Bad enough for Joe, not only does drinking create problems within his home and his work, it effects his body mostly me for that matter. Drinking could cause several different problems being that of a little damage to more damage than anyone would want. It could create cell damage, enlargement of kidneys, and harm to the hormones that control the kidney function. The alcohol Joe is enriching his body in is making an ionic imbalance this is really bad for the metabolic process. With Joe being so stressed out all the time it gives him high blood pressure this makes me nervous that I’m going to get chronic kidney disease.
The heart is the pump that pushes the blood around the body. It is about the size of a clenched fist and sits in the centre of your chest behind your rib cage and sternum. The heart is surrounded by a number of vessels that carry blood either towards the heart or away from the heart. The blood carried by the vessel can either
