Flashcards in systems Deck (50):
1

Diastolic pressure

pressure in your blood vessels when your heart rests between beats.

2

Systalic pressure

measures the pressure in your blood vessels when your heart beats

3

Heartbeat

The contraction of the heart muscle which occurs about 60-100 times per minute

4

Pulse

ryhthmic beating of the artereies as blood is moved through them

5

pacemaker

Electrical impulses from the heart muscle that cause your heart to beat

6

oxygen

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

7

Cabon dioxide

The gas in the air produced by respiration and used by plants as part of photosynthesis.

8

Cellular respiration

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

9

Denatured

the condition of proteins after they have been overheated

10

substrate

a substance acted upon by an enzyme

11

Burping

release of swallowed gas through the mouth

12

hiccups

an involuntary spasm of the diaphragm which creates a gulping sound

13

Heartburn

burning sensation caused by stomach acid rising into the oesophagus

14

flatulence or fart

releasing of gas through the anus.This gas is made from bacteria in the large intestine

15

Diarrhoea

excessive discharge of water faeces

16

rate rise

the hollow tubes with thick walls that cary blood from the heart to the other parts of the body

17

veins

blood vessels that cary blood back to the heart

18

Capillary

minature tubes that cary blood to the body cells .every cell in the body is supplied with blood through capillaries

19

Oxygenated Blood

Oxygen that has passed through the lungs and no oxygen has been removed

20

deoxygenated blood

Blood from which some oxygen has been removed

21

Breathing

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.

22

Digestion

The process in which food is broken down using mechanical and chemical digestion and eventually egested through the anus

23

Mechanical digestion

Physically breaking down the food into small pieces such as using your teeth to chew

24

Chemical digestion

Breaking down the food into simpler nutrients that can be used by the cells.involves the use of saliva and enzymes

25

Alimentary canal

Pathway from the mouth to the anus.digestion of food moves using the alimentary canal

26

Enzymes

Substance produced by a living organism that helps the process of digestion

27

Saliva

Watery substance in the mouth that moistens the food before swallowing

28

Pancreas

A large gland located behind the stomach which secrets digestive enzymes into the duodenum

29

Colon

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.

30

Large intestine

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.

31

Rectum

Temporarily stores feces before the feces is then egested the body through anus.

32

Anus

An opening at the end of the alimentary canal through which solid waste matter leaves the body.

33

Valves

Helps blood flow to nor go back in the direction it came from

34

Blood pressure

the pressure of the blood in the circulatory system

35

Salivary glands

Glands that produce saliva

36

Bolus

food that has been chewed and mixed in the mouth with saliva and passed into the osephegus

37

Oesophegus

Food pipe that connects the mouth to the stomach

38

Peristalsis

Contractions in the osephegus to help the food go down

39

Stomach

Large muscular organ that mixes food with gastric juice to start to break down proteins.Temporarily stores food
