Flashcards in systems Deck (50):
pressure in your blood vessels when your heart rests between beats.
measures the pressure in your blood vessels when your heart beats
The contraction of the heart muscle which occurs about 60-100 times per minute
ryhthmic beating of the artereies as blood is moved through them
Electrical impulses from the heart muscle that cause your heart to beat
the gas in the air and water that humans and animals breathe in.Oxygen is made up of two oxygen atoms .Plants produce oxygen as part of photosynthesis
The gas in the air produced by respiration and used by plants as part of photosynthesis.
The chemical reaction involving oxygen that moves the energy in glucose into the compound atp.The body is then able to use the energy contained in ATP
the condition of proteins after they have been overheated
a substance acted upon by an enzyme
release of swallowed gas through the mouth
an involuntary spasm of the diaphragm which creates a gulping sound
burning sensation caused by stomach acid rising into the oesophagus
flatulence or fart
releasing of gas through the anus.This gas is made from bacteria in the large intestine
excessive discharge of water faeces
the hollow tubes with thick walls that cary blood from the heart to the other parts of the body
blood vessels that cary blood back to the heart
minature tubes that cary blood to the body cells .every cell in the body is supplied with blood through capillaries
Oxygen that has passed through the lungs and no oxygen has been removed
Blood from which some oxygen has been removed
Process of respiration where air is taken into the lungs through the nose or mouth due to muscle contraction and taking it away due to muscle relaxation.
The process in which food is broken down using mechanical and chemical digestion and eventually egested through the anus
Physically breaking down the food into small pieces such as using your teeth to chew
Breaking down the food into simpler nutrients that can be used by the cells.involves the use of saliva and enzymes
Pathway from the mouth to the anus.digestion of food moves using the alimentary canal
Substance produced by a living organism that helps the process of digestion
Watery substance in the mouth that moistens the food before swallowing
A large gland located behind the stomach which secrets digestive enzymes into the duodenum
Part of the large intestine where a food mass passes from the small intestine and where water and other other remaining essential nutrient are absorbed into the body.
Responsible for the absorption of water, vitamins and minerals from our food.contains bacteria, which help digest some food types and are why we get gas.
Temporarily stores feces before the feces is then egested the body through anus.
An opening at the end of the alimentary canal through which solid waste matter leaves the body.
Helps blood flow to nor go back in the direction it came from
the pressure of the blood in the circulatory system
Glands that produce saliva
food that has been chewed and mixed in the mouth with saliva and passed into the osephegus
Food pipe that connects the mouth to the stomach
Contractions in the osephegus to help the food go down
Large muscular organ that mixes food with gastric juice to start to break down proteins.Temporarily stores food
Red blood cells
White blood cells
