Explanation / Answer

1.Digestive system:it includes digestion,absorption,assimilation in various parts of alimentary canal and assosiated digestive glands.

Digestive glands include cells such as salivary glands,the liver and pancreas are connected through series of ducts.

It includes parts like serosa,muscularis,submucosa,mucosa,palate,tooth,tongue and its associated tongue muscle,papillae.

Pharynx--nasopharynx,oropharynx,laryngopharynx,followed by oesophagus,stomach,small intestine-duodenum,jejunum,ileum,circular folds and villi,large intestine-caecum,colon and rectum anal canal.

Disorders: jaundice,-prehepatic,hepatic,extra hepatic

Vomiting,diarrhoea,constipation,indigestion.

Facts:1.The fangs of venomous snake are modified maxillary teeth.

2.Tusks are the enlarged elongated teeth which projects outside jaws eg: incisors of elephant.

3.Achalsia cardi is a condition in which lower oesophageal sphincter fails to relax normally as food approach.

4.GERD: gastrooesophageal reflux disease iaia chronic condition which lower oesophageal sphincter allows gastric juice to back flow into oesophagus causing heartburn,acid indigestion.

2.RESPIRATORY SYSTEM:

Includes: nose,pharynx,larynx,trachea,bronchi and bronchioles and lungs

Organs: skin,lungs

Exchange of gases occurs through trachea, primary bronchi,secondary,tertiary,primary bronchiole,secondary bronchiole,tertiary bronchiole,terminal bronchiole,alveolar ducts and alveolar sacs.

Inhalation and exhalation involves contaction of diaphragm,external intercoastal muscles,in anterio posterior axis.

Disorders: asthma,emphysema,silicosis,SARS,LUNG CANCER,hering-breuer reflex

Special movements: cough,sneezing,hiccuping,yawning,hypoxia

3.CIRCULATORY SYSTEM

plasma,formed elements,clotting of blood.Heart,cardiac action electrocardiogram,blood vessels--arteries,capillaries,veins,bp

Disorders: High BP,CAD,MI,Angina pectoris,Heart failure

Facts: bradycardia--slow heart rate,tachycardia-rapid heart rate,fibrillation-rapid uncontrolled heart beat

4.EXCRETORY SYSTEM

includes: kidneys,ureters,urinary bladder,urethra

Undergo: glomerular filteration,tubular secretion and reabsorption and mechanism of filtrate concentration.

Role of other organs: lungs,liver,skin,intestine

Disorders: glomerulonephritis,uremia,renal failure,(acute and chronic),

Facts: hemodialysis,peritoneal dialysis,kidney transplantation.

5.SKELETAL SYSTEM

includes:muscle fibre,traid system,myofibril,myofilaments,contractile proteins.

Characteristics: muscle twitches,refractory period,all or none law,frequency of stimulation,muscle tone,isotonic or isometric contaction.

Axial system: skull,vertebral coloum,thoracic skeleton

Appendicular: pectoral girdle,upper limbs,pelvic girdle,lower limbs

Disorders: myasthenia gravis,muscular dysrophy,tetany,arthritis,osteoporosis

Facts: rigor mortis,single unit smooth muscle tissue,multi unit smooth tissue,hypertrophy,fracture.
