Week 1:
REGULATION OF INTERNAL ENVIRONMENT
CONTENT
– Homeostasis, mechanism and structures of homeostasis
– Structures of the Kidney
– Functions of the Kidney
– Kidney diseases, effects and remedy
HOMEOSTASIS
Homeostasis is the process by which a fairly constant internal environment is maintained in an organism. The internal environment of an organism is made up of the body fluid such as blood, lymph and tissue fluid. For efficient functions of body cells and healthy growth, a living organism must be able to adjust to any change in the physical and chemical conditions of its body fluids. These conditions include temperature, PH, osmotic pressure, concentrations of dissolved substances and mineral ions.
MECHANISM OF HOMEOSTASIS
Homeostatic processes are control mechanisms which are used to detect and adjust to changes in the internal environment of the organism. These mechanisms usually include:
a. Sensory detectors which recognize a change in a given condition and stimulate the relevant body parts.
b. Effectors organs or glands which react and restore the normal state.

WEEK TWO
LIVER AND SKIN: STRUCTURE, FUNCTIONS, DISEASES AND CARE
CONTENT
– Structure and functions of the liver
– Diseases, effects and remedy of liver diseases
– Structure of the skin
– Functions, diseases and care of the skin
– Temperature regulation
– Control of body temperature
STRUCTURE OF THE LIVER
The liver is the largest organ in the body of a mammal with a weight of about 1.25kg. It is reddish brown, soft with two lobes and it is located below the diaphragm on the right side of the abdomen. It partly overlaps the stomach and has bile duct connecting it to the duodenum. The duct is attached to the gall bladder… Click here to order the complete first term Biology Lesson Note for SS3

HORMONAL CO-ORDINATION
CONTENT
– Hormones and endocrine glands
– Pituitary hormone
– Thyroid hormone
– Parathyroid hormone
– Pancreatic hormone
– Adrenal hormone
– Reproductive hormones
– Plant hormones
– Application of hormones to agriculture
HORMONES AND ENDOCRINE GLANDS
Hormones are chemical substances produced or secreted by endocrine glands (ductless glands) in response to various stimuli. Hormones are secreted into the bloodstream and circulated to exert their effect on their target organs. This effect could be to speed up or slow down biological reactions.
A few hormones like thyroxine and other growth hormones exert their effects on all body cells. A hormone can therefore be… Click here to order the complete Lesson Note on Biology SS3 first term
