• passage that leads to the anus

  Digestive tract
• Hallow muscular tube/passageway for the digestive and respiratory system

  Pharynx
• Digestive tract of the Arthopads And molluses

  digestive glands
• passageway for the digestive and respiratory system

  Esophagus
• Expandable walls

  Stomach
• Coiled organ

  Small intestine
• Initial region

  Mouth or buccal cavity
• Near the stomach

  Duodenum
• • The Last part

  Large intestine
• • Opening to the outside

  Anus
• • yellowish organ

  Pancreas
• • Yellow green substance

  Liver
• • Semi-solid mass called

  Bolus
• • Food moves down the esophagus by waves of muscle contraction called

  Peristalsis
• PMAT

  Prophase -first phase of mitosis

  metaphase -duplicated chromosomes

  anaphase -sister chromatids separate and move to opposite ends of the cell

  telophase -final stage of cell division
• • Final phase of cell division where the cytoplasm and organelles are divided between daughter cells

  Cytokinesis
• Produce two daughter cells with same amount

  Mitosis
• • DNA

  Deoxyribonucleic acid
• • RNA


  
Ribonucleic acid
• prevents the food from entering the respiratory tract / flap of tissue

  epiglottis
• • Process of digestion

  Ingestion

  digestion

  absorption

  egestion
• this phase is sometimes referred to as the RESTING PLACE

  Interphase
• the stage where the duplicated chromosomes align in the middle, ready to be separated

  Metaphase
• Replication is the process of making exact copies of this material.

  Choromosomes
• during this phase, the separated chromosomes reach the opposite ends of the cell

  Telophase II
• the chromosomes align themselves along an imaginary line called equator

  Metaphase II
• • when parent have kids, each child is unique and doesn't look exactly like their parents or siblings due to

  meiosis
• gene of factor that is masked by the dominant gene

  recessive gene
• the genetic makeup of the individuals

  genotype
• FATHER OF GENETICS

  Gregor Mendel
• difference among members of a population

  variations
• is the transmission of genes from one generations to the next

  Heridity
• it is the genes that occupy the same locus in the homologous chromosomes

  Alleles
• the sum total of all genotype of all individuals in a given population

  Genepool
• it is a field of studies that deals with heredity and variations

  Genetics
• this crucial for creating genetic diversity and ensuring each new cell gets the right amount of DNA

  Metaphase I
• is one half of a duplicated chromosome joined to its identical copy by a centromere

  Chromatids
• are small structures in animal cells that duplicated and help in cell division by forming spindle fibers

  Centrioles
• is the process where cells change and acquire specialized functions

  Differentiation
• is the ability of certain animals to grow back lost body parts after they have been cut off.
