Bio II Lab Final
Chapter 11
Abdominal System/Cavity pg 169
(Inside of a Pig)
Contains organs of the digestive system
Stomach – stores food and has numerous gastric glands which secrete gastric juice and causes protein to be digested
Small Intestine – receives secretions from the pancreas and gallbladder
Large Intestine – absorbs water and prepares feces for defecation at the anus
Liver – largest organ in the abdomen, disposes of worn out blood cells, producing bile, stores glycogen, maintains the blood glucose level and produces blood proteins
List all the organs and functions
Urinary System pg 185
kidney (different parts of the kidney)
Renal Cortex – a granular region which contain most regions of the nephrons
Renal Medulla – contains the renal pyramids consisting of the loops of nephrons and collecting ducts
Renal Pelvis – where irons collects from the collecting ducts
Glomerular Capsule – forms cupcake like structure, inner layer pores allow glomerular filtration to occur
Proximal Convoluted Tubule – inner later has many microvilli which allows tubular reabsorption
Loop of the Nephron – forms U shaped position functions in water absorption
Distal convoluted Tubule – second section that lacks microvilli and functions on tubular secretion
Afferent Arteriole – brings arteriolar blood toward glomerular capsule
Glomerulus – Capillary fudge cropped by glomerular capsule
Efferent Arteriole – takes arteriolar blood away from glomerular capsule
Peritubular capillary network – capillary bed that envelops the rest of the nephron
Venule – takes venous blood away from the nephron
Nervous System pg 193
The brain holds parts and centers which receive input from and can command other regions of the nervous system
Sheep Brain pg 211
Ventricles – interconnecting spaces that makes cerebrospinal fluid which cushions the brain
Cerebrum – responsible for higher mental capabilities , divided into left and right cerebral hemispheres, joined by corpus collision
Frontal lobe – controls motor functions and permits voluntary muscle control (problem solve, speak, and smell)
Parietal Lobe – received information from sensory receptors located in the skin and also the taste receptors in the mouth
Occipital Lobe – interprets visual input and combines visual images with other sensory experiences
Temporal Lobe – sensory areas for hearing and smelling
Diencephalon – part of the brain where third ventricle is located
Thalamus – two connected loves located in the roof of third ventricle
Hypothalamus – forms the floor smell of the third
Brain Stem – part of the brain that connects with the spinal cord, its location serves as a relay station for nerve impulses passing from the cord to the brain
Brain
Neuron
pg 213-214, 216
Reproductive System
Testes – males sex organ where sperm and hormones are produced
Epididymis – a tightly coiled tube where sperm is stored until mature
Vas Deferens – muscular tube that conducts sperm to ejaculatory duct
Ejaculatory Duct – where the vas deferens and duct from seminal vesicle meet
Urethra – located in the penis, conducts semen or conducts urine to the exterior and doesn’t pass at he same time
pg 220
Zygote – 2 cell – 4 cell – 8 cell – Morula – Blastula
cleaveage 1 2 4 6
Early Gastrula Stage – when certain cells push or invaginate into blastocoele creating double layer of cells
Late Gastrula Stage – hasty ration isn’t complete until 3 layers of cells form, the 3rd later called mesoderm occurs between other two layers mentioned
