Example of outer work. Outer work is the overcoming of the outside pressure through a certain distance by means of expanding. As the piston in the image is lowered, no outer work is done. Inner work is done. Inner work is the to push molecules farther apart against the force of cohesion that is trying to hold them together.

Isothermal expansion is a change in a system with a constant temperature. This occurs when: 

A. Said system is in contact with an outside heat source 
and
B. The change in temperature is slow enough so that the reservoir can adjust through heat exchange.

The cycle of the heart in its diastole (relaxation) state and its systole (contraction) state. The ventricles can be in a diastolic state, while the atria can be in a systolic state. An auricle is a small conical projection coming out of the atrium, but in some texts it represents the actual atrium. As the heart relaxes, blood enters from the other side and into the atria, then leaves and enters the ventricles. When the heart contracts, blood leaves the ventricles and goes back into the body.

A complex anatomical view of the heart. RA is the right atrium, or auricle, which receives the deoxygenated blood by way of two superior vena cava (SVC) and one inferior vena cava (IVC). The blood passes through the right ventricle (RV) and is pumped up to the lungs via the pulmonary arteries (PA). At the lungs, the blood is reoxygenated and returns via the pulmonary vein (PV) and left atrium/auricle (LA). From there, the blood is passed to the left ventricle (LV) where the blood is pumped up through the systematic arch (SA) to the body. The systematic arch gives off a right innominate artery (INN), where the blood is then passed to the right and left carotid (C) and subclavian (SCL), where the blood goes to the head and arms respectively. It continues dorsally to the dorsal aorta (DA), which is the main artery that distributes blood to the whole body. TR is the windpipe, or trachea, BR is the bronchial tube that carries air to the lungs, and BV is a blood vessel on the wall of the heart.

Striped, or striated, muscle which quickly contracts causing the alternating black and white lines. It has very delicate fibers (M FL). It is stimulated by nerve fibers (N F), which divide into an endplate (N E) on the contracting surface. N are nuclei, which are a part of elongated cells that fused together to make the muscle. M stands for muscle and N, except for nuclei, stands for nerve.

A simple nerve cell, or neuron. N is the nucleus of the cell, NC is the cytoplasm, D are dendrites which are fine protoplasmic branches that create synapses that connect to another nerve cell. The neuron is connected to muscle (MU) by a nerve fiber (NF). The fiber is covered by a sheath (SH) of fat to protect it. NE is the ending of the fiber that the muscle is connected to. LB is a lateral branch of the nerve fiber.

Illustration of the reflex action of an animal. SE is the sensory nerve-ending. A stimulus passes through the sensory nerve-fiber SF to a nerve-cell SC in the ganglion of a dorsal or afferent (convey towards the center) root (DR) of a spinal nerve. The fiber divides in the spinal cord (SP C) where the message is relayed to an internuncial nerve-cell (A). MO is motor nerve-cell, VR is ventral or efferent nerve, ME is nerve plate, and MU is muscle fiber.
