Kidney Dissection Lab

Hey there everyone. We are going to cut some more organs. Enjoy!
LAB WORK REPORT
Title: Kidney Dissection Lab.
Introduction: Kidneys are purplish-brown organs and located below the ribs toward the middle of the back. Their function is to remove liquid waste from the blood in the form of urine; keep a stable balance of salts and other substances in the blood; and produce erythropoietin, a hormone that aids the formation of red blood cells. The kidneys remove urea from the blood through tiny filtering units called nephrons. Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule. Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney.
Purpose: to be able to explain excretory system and organs functions, urine formation and related diseases; describe blood flow through kidney structures using sequential transition words (subsequently, previously, eventually, next, before (this), afterwards, after (this), then).
Equipment:
Procedure:
  1. Examine and identify the outside of the kidney. The ureter [yu'ri:te], renal artery, and renal vein all enter the kidney in the same area. If they are present, the ureter can be identified by the larger amount of fat tissue that is usually attached to it.
  2. Letting the kidney lie flat, cut the kidney in half lengthwise from the side. Do not cut until you have checked and are sure of the correct direction of your cut—As a surgeon, you only get one chance to cut, and there is no way to redo this!
  3. Splitting the kidney in half will show its internal structures. Examine the kidney and the diagram to identify these structures. There are several parts to the kidney, as shown on the picture. From the outside to the centre of the kidney, find each of the following in your organ.
  4. Use flagged pins to identify the following parts of the internal kidney. 
  5. After you have identified all the structures in the kidney, work with your group to trace the path taken through your group’s kidney by the blood, and by the filtrate that becomes the urine. As you do this, point out and name all the structures that are involved. When your group is satisfied that you can do this well, your group should use the kidney to explain it to the teacher!
Result:
  1. Draw the picture of the kidney showing all parts that you have identified.
Conclusion (answer these questions):
  1. What is the main function of the kidney? 
  2. Describe the pathway of blood through the kidney. 
  3. How did you distinguish between the renal artery and the renal vein? 
  4. Which area of the kidney contains the glomeruli and Bowman’s capsules? 
  5. In which part of the kidney does the majority of water reabsorption occur? 
  6. What structure carries urine out of the kidney and where does it go?
Vocabulary⬇
Calyx - cup-like division found in the renal medulla; minor calyces (plural) empty into major calyces.
Renal artery - branch from the abdominal aorta that supplies the kidney with oxygenated blood.
Renal capsule - dense, irregular connective tissue layer that protects the kidney and helps maintain its shape.
Renal corpuscle - glomerulus enclosed within a glomerular capsule; site of filtration.
Renal cortex - outer region of the kidney.
Renal medulla - inner portion of the kidney.
Renal pelvis - large cavity that receives urine from major calyces; continuous with ureter.
Renal pyramid - cone-shaped structure found in the medulla with its base facing the cortex and the apex facing the renal artery.
Renal vein - blood vessel exiting the kidney carrying filtered, deoxygenated blood to the inferior vena cava.
Ureter - tube that connects the kidney to the urinary bladder.

Chicken Dissection Lab

LAB WORK REPORT
Title: Chicken Dissection Lab.
Introduction: Bird anatomy shows many unique adaptations, mostly helping flight. Birds have a light skeletal system and light but powerful muscles which, along with circulatory and respiratory systems capable of very high metabolism and oxygen supply, allow the bird to fly. There is a relationship between beak and specially adapted digestive system.
Purpose: to Identify the major internal organs of a bird. To compare and contrast human and bird internal organs, structures, and systems.
Hypothesis: Even though humans and birds do not look the same, we share almost similar organs and body parts. Hmmm.
Equipment:
Procedure:
  1. Identify external anatomical features of a bird.
comb
beak (no salivary glands - no digestion in a mouth)
ear lobe (colour!)
scale on the legs

  1. Identify a few major internal organs of a bird.
esophagus
crop (a pouch in a bird's gullet where food is stored or prepared for digestion)
keel bone
liver
gallbladder
heart
gizzard
intestines
spleen
small intestine
caecum
cloaca
follicle
uterus
lungs
air sacs
  1. Compare and contrast human and bird internal organs, structures, and systems.
Result:
  1. Draw the picture of the bird with internal and external features.
  2. Write usual result like in a Sample Lab Work.
Conclusion:


Write usual Conclusion like in a Sample Lab Work.

Возвращение ПРОЕКТОВ. Ботаник - получи 5!

Доброго времени суток, дорогие друзья. Каждый десятиклассник должен и любой лицеист седьмого или восьмого класса может сделать, оформить, показать и сдать на всеобщее обозрение проект по биологии. Темой проекта может являться заданная тема в разных вариациях в зависимости от понимания учащегося и данной цели учителя. В результате, выполненная работа и права на нее переходят в пользование Biology Department LI7. В одной параллели не более пяти людей могут взять одну тему и работать над ней. Дополнительную и напутственную информацию можно взять у учителя биологии.
Оценки даются соответственно:
Две пятерки - за выполненный проект, выступление перед соратниками и проектный лист.
Три пятерки - за выполненный проект, выступление перед соратниками, проектный лист и электронную презентацию.
Четыре пятерки - за выполненный проект, выступление перед соратниками, проектный лист, презентацию и все это на английском языке.
Пять пятерок - плюс ко всему, если есть классное видео!
Темы проектов:
1. Использование молотого использованного кофе в качестве биоудобрения
2. Адаптационные способности растения ____________ по анализу его фенотипических признаков ___________ на территории ____________
3. ________________  и их роль в биоценозе ...
4. Беспозвоночные – гидробионты как биоиндикаторы
5. Исследование фауны беспозвоночных животных озер и болот г. Казани (что-то определенное в одном месте). Какие факторы влияют на распространение?
6. Использование суперабсорбентов для уменьшения использования воды для полива.
7. Новый дизайн аквариума для черепах.
8. Растения в движении! Эксперименты на фототропизм растений.
9. Адаптационные способности гриба ____________ по анализу его фенотипических (внешних) признаков мицелия (микроскопического строения).

Digestion at classtime

Hey everyone. There is a small video quiz. You have only ten minutes. GO!
LINK
The digestive system includes the organs of the alimentary canal and accessory structures. The alimentary canal forms a continuous tube that is open to the outside environment at both ends. The organs of the alimentary canal are the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The accessory digestive structures include the teeth, tongue, salivary glands, liver, pancreas, and gallbladder.
After you've chewed food, you push food to the back of your mouth with your tongue. That's a conscious act using voluntary muscles. The other processes are automatic. The epiglottis closes off your trachea - the tube to your lungs. This stops food from going down the trachea. Instead, it goes down the esophagus towards the stomach.
Like the esophagus, your stomach is wrapped in layers of muscles. They also contract in a peristaltic rhythm - contract in waves. This mixes the food with liquids that your stomach produces. These are gastric juices secreted by microscopic glands that line the inner wall of your stomach. Stomach glands secrete two digestive substances: enzyme pepsinogen and hydrochloric acid. The acid converts pepsinogen into pepsin, an active enzyme pepsin breaks down complex protein molecules. Break down of sugars and fats happen in your small intestine.
This steady contraction and relaxation is called peristalsis. It occurs throughout your digestive system.
