EXAM SCIENCE💞

• 3 PARTS OF THE SMALL INTESTINE

  DUODENUM

  JEJUNUM

  ILEUM
• 4 ACCESSORY ORGANS

  -SALIVARY GLANDS

  -PANCREAS

  -LIVER

  -GALL BLADDER
• 3 ENZYMES SECRETED BY THE SMALL INTESTINE

  -AMYLASE

  -MALTASE

  -LACTASE
• 2 KINDS OF DIGESTION

  -MECHANICAL DIGESTION

  -CHEMICAL DIGESTION
• INGESTION -FIRST PROCESS THAT HAPPENS IN THE DIGESTIVE SYSTEM
• Chemical Digestion -uses certain enzymes to break down nutrients, such as carbohydrates, proteins, and fats, into smaller molecules
• Bile -A green fluid that turns large fat droplets into smaller ones
• Small intestine- final digestion, breaks down food food furthering substances
• teeth -cut, crush, and break it apart into tiny pieces
• Liver -the largest internal organ
• Gall bladder - small, pear-shaped organ on the right side of your abdomen, just beneath your liver.
• Saliva - extracellular fluid produced and secreted by salivary glands in the mouth
• Assimilation- the process in which digested foods are distributed into different parts of the body
• Ingestion - the intake of food that provides energy and nutrients
• Small intestine - final digestion
• Amylase - enzymes present in saliva that breakdown starch
• Lage intestine - reabsorbs water from chyme
• Intestinal villi - increas surface area for nutrients absorption
• Pepsin - enzyme that digest protein in the stomach
• G1 - stage up cell cycle that the cell increas in size
• S phase - Dna is synthesized and chromosomes are replicated
• Interphase - where DNA replication occour
• Metaphase - chromosomes are lined up at the equatorial plane
• Telophase - last phase of nuclear division
• Anaphase - chromatids separate at the centrome
• Prophase - condensed chromosomes become visible
• Xy chromosomes - indicates a normal human male
• 46 - number of chromosomes produced during mitosis
• Gametogenis - Sex xell
• Digestion - the process in the alimentary canal by which food is broken up
• George Mendel - father of genetics
• Chromosomes - an organized structure of DNA
• Mitosis - process by which a single parent cell divides to make two new daughter cell
• Meiosis - a process where single cell divides twice to produce four more cells containing half the originl amount of the genetics information
• Genetics - the study of heredity and variation of inherited characteristics
• Genes - the basic unit of heredity passed from parent to child
• Mitochondria - power house òf the cell
• Cell - basic unit of life
• Allele - is one or two more version of DNA sequence
• Recessive Traits - refers to the trait that is expressed only when genotype is homozygous
