The digestive system is very important to the body. Without it‚ we would not be able to live. It is a series of hollow organs joined in a long‚ twisting tube from the mouth to the anus. The tubes actually are about 30 feet long if they were stretched out‚ but seem smaller because of the way they are wrapped around. The main parts are the mouth‚ teeth‚ esophagus‚ stomach‚ small intestines‚ large intestines‚ colon‚ rectum‚ and anus. The pancreas‚ gallbladder‚ and liver are also key parts because of

where it is exhaled. (P. 200) The Digestive System Explain the function of the digestive system (everyone) The digestive system is the physical ad chemical breakdown of food. Following ingestion‚ food and fluids are processed by the digestive organs so that nutrients can be absorbed from the intestines and circulated around the body. Any residue of food that is not digested is solidified and eliminated from the body in the form of feces. (P.207) What are digestive enzymes and what do they do? (A-M)

nucleus and acrosome. The nucleus is the control centre of the cell and holds (DNA)‚ this is what makes this cell a eukaryotic cell. The acrosome is an organelle that forms on the outside of the head they derive from the Golgi apparatus and contain digestive enzymes. Acrosomes are needed to break down the outer membrane of the egg‚ so that the two nucleuses’ can fuse together thus producing a zygote (fertilized egg).The mid piece holds the centriole and mitochondrion. The centriole is necessary for the

Biology Digestive Enzyme Experiment “Design an experiment in which you will investigate a digestive enzyme’s effect on digestion” Research Question: To determine the effect of enzyme concentration on the rate of digestion. This will be done by increasing the concentration of the enzyme diastase and investigate its effect on the rate of starch digestion. The rate will be determined by the amount of time it takes to completely digest the powdered starch‚ the complete digestion will be indicated by

Similarly‚ cells within tissues and organs must be anchored to one another and attached to components of the extracellular matrix. Cells have developed several types of junctional complexes to serve these functions‚ and in each case‚ anchoring proteins extend through

Basilica de San Martin de Tours Basilica de San Martin de Tours is considered to be the largest church in the Philippines and in Asia. The construction of the church was spearheaded by Father Diego Espinar in 1575. The town of Taal‚ Batangas is located in the Archdiocese of Lipa‚ Batangas. St. Martin de Tours is the patron saint of the said town‚ whose fiesta or feast day is celebrated every November 11. In 1754‚ the church was destroyed along with its neighbouring town‚ Taal‚ in the largest eruption

essential for the absorption of digested nutrients. The cells of the villi transport food from the digestive tract into the bloodstream where they can be used by the body. The villi aid in absorption by increasing the surface area of the intestine and they contain specialized cells which transport different types of nutrients into the blood.

If the player lands on the beginning of one of the organs‚ you have to draw one of the cards for the respective organs from the pile and answer a question about the functions of it. If you answer the question correctly‚ you can open the pop-up flap to see how far forward you can move. The different amount of squares you can move forward differ according to the organ you land on.

mechanisms associated with the digestive system The gastrointestinal tract is a lymphoid organ‚ and the lymphoid tissue within it is collectively referred to as the gut-associated lymphoid tissue or GALT. The number of lymphocytes in the GALT is roughly equivalent to those in the spleen‚ and‚ based on location‚ these cells are distributed in three basic populations: 1. Peyer’s Patches: These are lymphoid follicles similar in many ways to lymph nodes‚ located in the mucosa and extending into the submucosa

ANIMAL CELL MODEL ORGANELLE FUNCTIONS Cell membrane: Separating the interior of the cell from the outside environment‚ the cell wall is selectively permeable‚ only letting certain things through. It is involved in a variety of cellular processes‚ such as cell adhesion and cell signalling. Cytoplasm: The fluid that fills the cell‚ cytoplasm uses its dissolved enzymes to break down larger molecules. The products can then be used by the organelles that are suspended in the cytoplasm. Cytoskeleton:
