Describe what happens to a meal of oily beans and maize from the time of ingestion up to the time of absorption

   In  the  mouth;  starch  in  maize;  is  digested  by  salivary  amylase/ptyalin/diastase  into  maltose;  food is  chewed  and  mixed  by  teeth  and  the  tongue;  rolled  into  boluses  by  peristalsis;  it  enters  into  the stomach  via  the  cardiac  sphincter;  in  the  stomach,  gastric  juice  containing  pepsinogen  that  is activated  to  pepsin;  digests  proteins  in  the  beans;  into  shorter  peptides;  food  is  churned  and allowed  into  the  duodenum;  via  the  pyloric  sphincter  muscle;  in  the  duodenum;  bile  juice secreted  by  the  gall  bladder;  emulsifies  the  oils  in  the  beans  into  tiny  oil  droplets;  pancreatic juice;  secreted  by  the  pancrease;  contains  pancreatic  amylase;  that  digests  starch  to  maltose; pancreatic  lipase;  that  digests  the  oil  in  the  beans  to  fatty  acids  and  glycerol;  trypsin;  digests proteins  into  shorter  peptides;    food  enters  into  the  ileum;  where  succus  entericus  is  secreted;  it contains  maltase  enzyme;  that  digests  the  maltose  into  glucose;  that  is  absorbed;  peptidase; digests  peptides  into  amino  acids;  lipase  digests  the  remaining  lipids  (oil)  into  fatty  acids  and glycerol;  which  is  absorbed  through  the  lacteals  of  the  villi;  Max.  20  mks

DESCRIBE THE ADAPTATIONS OF THE ILEUM TO ITS FUNCTION (20 MARKS)

-
Has secretory glands/crypts of lieberkuhn which secretes enzymes (maltase/sucrase/lactase/peptidase/lipase to complete digestion of sugars/proteins/lipids. Goblet cells secrete mucus which allows for smooth movement of food and protect wall of ileum from action of digestive enzymes Very long to provide large surface area for absorption. Highly folded/coiled to slow movement of food to allow more time for digestion/absorption/ and to increase surface area for absorption. Has numerous villi which increase surface area for absorption/microvilli which further increase surface area for absorption. Ileum wall/villi have thin epithelium which is only one cell thick to reduce distance over which digested food has to diffuse. Villi are highly vascularised/have a rich network of blood capillaries for rapid transport from small intestines and maintain a steep concentration gradient for rapid absorption. Villi have lacteals for absorption of fatty acids and glycerol Cells of ileum wall h...

Explain how structures of the human ear are adapted to their functions. (20 marks)

Image
The pinna;- is funnel shaped to trap sound waves; cartilaginous to maintain the funnel shape; collects and directs sound waves into the external auditory meatus ear; The external auditory canal; - a tube connected to the pinna that directs sound waves from the pinna to the eardrum lining the auditory canal; has hair that trap foreign particles; The canal contains wax-secreting cells; and hair which traps dust particles; and pathogenic bacteria hence prevent them from getting into the ear; The eardrum; - has a thin tough membrane; that easily vibrates when hit by sound waves; transferring them into vibrations. The ear ossiscles; - they act like a layer and they easily move forward and backward to amplify sound vibrations that hit them; The suspensory ligaments; - suspends the ear ossicles and prevents excessive vibration that would otherwise damage the inner parts of the ear; The eustachian tube - it connects the middle ear with the pharynx; and it equalises air pressure between...

KCSE 2010 Q8. Describe how a finned fish such as Tilapia moves in water. (20 marks)

-
The following describes how  a finned fish such as Tilapia moves in water . v       Water is denser than air. The density of water supports fish and provides a medium in which it swims. v       It has a streamlined body; reducing resistance, thus easily swims in the water. v       The scales overlap pointing backwards allowing water to pass over the fish without obstruction. Mucus is also secreted over the scales reducing friction during movement. v       They have a flexible backbone onto which segments of muscle blocks, myotomes, are attached. The muscles contract and relax bringing about undulating movements. v       The fish have fins that help in steering and balancing fish during swimming. v       The pectoral and pelvic fins are paired. They are used for braking, steering and v   ...
