I JUST HAVE THIS SUMMARY........PLEASE LET ME KNOW IF I HELPED

Summary

1. Rat is a mammal which has almost similar characteristics to the human.

2. The digestive system is a system found inside the animal, start from the

mouth and ends with the anus, and helps in digestion.

3. The process of enzymatic breakdown of complex food materials into the

simplest form or absorbable form for cells is called digestion.

4. The respiratory system is the system which is used to inhale oxygen,

oxidation of food and exhale carbon dioxide. The rat respiratory system

consists of nostrils, lungs, a trachea and a larynx.

5. Excretory system/urinary system helps in removal of wastes while

reproductive system helps in formation of gametes (ovum and sperm),

bringing ovum and sperm together, provide nourishment for the embryo

or fetus until birth and regulation of the hormones for the development of

sexual characteristics.

6. The life cycle of the rice plant is divided into three growth stages: Vegetative

growth stage, Reproductive growth stages and Ripening growth stages.

7. Rainy days or low temperatures may lengthen the ripening phase, while

sunny and warm days may shorten it.

8. The endocrine system is the collection of glands that produce hormones

that regulate metabolism, growth and development, function of tissue,

reproduction, sleep, and mood.

9. Pituitary gland is often called as the “master gland” as its hormones control

other parts of the endocrine system.

10. Growth hormone (GH) or Somatotropic hormone stimulates the growth of

all tissues of the body, especially skeletal muscle and bone.

11. The thyroid gland secretes two hormones: thyroxine and calcitonin.

12. The parathyroids produce a hormone called parathyroid hormone (PTH).

13. The adrenal glands produce a variety of hormones including adrenaline and

the steroids aldosterone and cortisol.

14. Sexcorticoids or Gonadocorticoids secrete androgen hormone in male while

oestrogen and progesterone hormone in female.

15. The endocrine system of the pancreas consists of islet cells (islets of

Langerhans) that secrete and release insulin and glucagon hormones directly

into the bloodstream.

16. The ovaries of the female, release two main hormones: Oestrogens and

Progesterone and the testis of male secrets testosterone hormone.
