esophagus
the part of the alimentary canal that connects the throat to the stomach; the gullet. In humans and other vertebrates it is a muscular tube lined with mucous membrane.
liver
The liver's main role is in the processing of the products of digestion into substances useful to the body. It also neutralizes harmful substances in the blood, secretes bile for the digestion of fats, synthesizes plasma proteins, and stores glycogen and some minerals and vitamins

6 H2O + 6 CO2 + solar energy ----changed to----> C6H12O6 + 6 O2
Glucose
C6H12O6
Investigation proving that ALL our body cells give off water and heat.
We put our hand in a bag and put the cobalt chloride in with it. And we sealed it all up. After shaking our hand for a few minutes the chloride turned pink which meant that water was being given off.
Mitochondria
an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers
Thymus
a lymphoid organ situated in the neck of vertebrates that produces T cells for the immune system. The human thymus becomes much smaller at the approach of puberty
large intestine
Part of the intestine that changes stool from a liquid to a solid form by absorbing water. Often simply called the colon, but in fact includes the appendix, cecum, colon, and rectum; has a total length of about 5 feet (1.5 m).
Systemic
refers to body cells
Pulmonary
refers to the lungs

pumps the blood away from the heart
eyelids
ach of the upper and lower folds of skin that cover the eye when closed.
Asthma
Causes - allergens, cigarette smoke, air pollution, cold air or changes in the weather,strong odors from painting or cooking, scented products, medicines such as aspirin and beta-blockers, Infections. Symptoms - Coughing, Wheezing, Chest tightness, Shortness of breath, Faster breathing or noisy breathing. Cure - Quick-relief medicines—taken at the first signs of asthma symptoms for immediate relief of these symptoms, Long-term control medicines—taken every day, usually over long periods of time, to prevent symptoms and asthma episodes or attacks.
Antibodies
blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances that the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.

atrium
accepts blood into the heart
Do we need plants? Do they need us
Yes we need plants because we need oxygen and plants create oxygen during photosynthesis. They need us because of carbon dioxide which we produce during cellular respiration.
iris
The colored part of the eye with a hole (pupil) in the center. It regulates the amount of light entering the eye
retina

Old air
4% CO2, 79% and 16% O2
Diaphragm
a dome-shaped, muscular partition separating the thorax from the abdomen in mammals. It plays a major role in breathing, as its contraction increases the volume of the thorax and so inflates the lungs.
