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



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
