Health Education Paper 2, WASSCE SC 2023

State three differences between the endocrine gland and exocrine gland.
Complete the table below by naming two examples of each of the glands in 7(a) and state one secretion of each.

3.Name the three main types of neurons.

4.Give three examples of reflex actions

Majority of the candidates avoided this question.

In part (a), majority of the candidates could not differentiate between endocrine glands and exocrine glands.

In part (b), majority of the candidates were able to give two examples of exocrine and endocrine glands as well as the names of their secretions.

In par (c), majority of the candidates correctly named three types of neurons.

In part (d), majority of the candidates gave three examples of reflex actions.

The expected answers are:

*Endocrine gland*	*Exocrine gland*
Secretes directly into the blood streams	Secretes through duct
Secretions affect target organs/tissues	Secretion acts directly on food substances
Point of secretion/glands is far from target organs/tissues	Point of secretion/glands not far from food substances
Secretes hormones	Does not secrete hormones

Note: Differences must correspond to score
