Artemia adult's blood circulation in the tail and appendages.
Artemia adult appendages with gills.
Artemia blood circulation in the head and around the gut.
Feathery-like appendages are in constant motion. Small pinchers at the front of the head distinguish that the organism is a female. Black dots at the top of the head are the eyes.
Artemia adult blood circulation along the gut.
Artemia naplius with contractions in the digestive tube.
Artemia blood has blood cells that circulate in an open circulatory system.
Artemia with coordinated motion of flipper-like appendages.
This organism is microscopic and does not cause disease and can be beneficial as a food source for other aquatic animals. A mm square grid is used to observe the measure of length of this organism.
Artemia nauplii use appendages as oars to propel themselves.
Artemia juvenile swimming motion.
Artemia adult tail.
Cardiac muscles are found only in the heart. They work together to bring deoxygenated blood in and push oxygenated blood out into the body. Essentially, they keep your heart pumping and your body alive.
Zebrafish embryos develop a heart and blood cells that start moving in an open circulatory system.
Zebrafish larvae have a pulsing heart and blood cells in a closed circulatory system.
Daphnia have a pulsing heart and blood cells that circulate in a closed circulatory system.
The three kinds of muscles-skeletal, cardiac, and smooth-all work in different ways and perform different functions in the human body.

Sounds are actually waves from vibrations. The outer ear catches these waves and funnels them down into the inner ear. The waves reach the eardrum and in turn make the eardrum vibrate. Three small bones receive these vibrations next, then a snail shell-shaped structure called the cochlea. The cochlea is filled with liquid, and this liquid stimulates hairs inside the inner ear. The hairs transmit the signal to the auditory nerve where the signal is taken to the brain and processed as sound.
