The ear and the mechanism of hearing

The ear converts the vibrations of air into electric signals which are then processed by the brain.

Human body (male)

This animation introduces the most important organ systems of the human body.

Effects of smoking on the lungs

Smoking severely damages the respiratory system, it may cause COPD or lung cancer.

The anatomy of the heart

This scene presents the location, anatomy and functioning of the central organ of the human circulatory system.

What is the human body composed of?

This scene presents the basic components of the human body.

Types of bone articulations

Human bones are joined together by cartilaginous or synovial joints, sutures or they can fuse together.

Synaptic transmission

Neurons transmit electrical signals via chemical and electrical synapses.

Voice production

When producing sound, the vocal cords are vibrated by the air flowing out of the lung.

Anatomy of the small intestine

The longest part of the digestive system, where most of the digestion and absorption takes place.

Connective tissues

Connective tissues include loose and dense connective tissues, adipose tissue, blood, tendon and bone tissue.

The human brain

The main parts of the human brain are the brain stem, the cerebellum, the diencephalon, and the cerebrum.

Mechanism of taste reception

Taste receptors convert chemical stimuli into electric signals.

Circulatory system

Systemic circulation carries oxygenated blood from the heart to the body, while pulmonary circulation carries oxygenated blood from the lungs to the heart.

Human teeth

Humans have 4 types of teeth: incisors, canines, premolars and molars.

Nose, the mechanism of smelling

Olfactory receptors produce electric signals when stimulated by odours.

Muscle tissues

The three types of muscle found in the human body are the smooth, the striated and the cardiac muscle.

Structure of skeletal muscles

This animation demonstrates the fine molecular structure and mechanism of muscles.

The mechanism of vision

The curvature of the lens of the eye changes when we look at a distant or at a near object, to ensure a sharp image.

Layers of the skin; cutaneous senses

The skin is the soft outer covering of our body, its three layers are the epidermis, the dermis and the hypodermis.

The sense of balance

The position and acceleration of the head is detected by the inner ear.
