A

filter toxins and waste from the blood

36
Q

nephrons

A

millions of tiny filtering units inside each kidney

37
Q

excretory system

A

removes cellular wastes from the body through the lungs, skin, and the urinary system

38
Q

digestive system

A

converts food into fuel and helps get rid of solid waste

39
Q

liver

A

makes bile, which breaks fats into simpler molecules

40
Q

gland

A

A group of cells that make special chemicals for the body.

41
Q

Nervous system

A

It is the structure that controls the actions and the reactions of the body in response to stimuli from the environment.

42
Q

Parts of the nervous system

A

Central nervous system and Peripheral nervous system.

43
Q

Central nervous system

A

It is made up of the brain is the central command organ and the spinal cord allows your brain to communicate with the rest of your body.

44
Q

Peripheral nervous system.

A

The PNS connects to the CNS to the rest of your body.

45
Q

Parts of Peripheral nervous system.

A

The sensory and the motor part.

46
Q

Involuntary

A

It means that the brain controls and you have no control. Example, your heart, blood pressure, body temperature and so forth.

47
Q

Voluntary

A

Actions of your brain you can control.

48
Q

Brain

A

It has three parts, Cerebrum, Cerebellum, and Brain stem.

49
Q

Cerebrum

A

Is where you think and solve problems, and is where most of your memories are stored. It controls everything that is voluntary. That includes, touch, sight, taste and so forth

50
Q

Cerebellum

A

It processes information from your body. It actually keeps track of your body positions and your movements.

51
Q

Brain stem

A

The brain stem connects your brain to your spinal cord. The medullas is part of the brain stem. It controls involuntary processes.

52
Q

Spinal Cord

A

It is made up of bundles of nerves.

53
Q

Nerves

A

It is a collection of nerve cells extension bundled together with blood vessels and connective tissue.

54
Q

Neuron

A

It is a cell that moves messages in the form of fast-moving electrical energy.

55
Q

Glial

A

This cells do not transmit nerve impulses, but they protect and support neurons.

56
Q

Sensory Neurons

A

It gathers information from in and around your body and sends it to your brain.

57
Q

Motor Neurons

A

They move impulses from the brain and spinal cord to other parts of the body.

58
Q

Dendrite

A

It is usually short, branched extension of the cells body.

59
Q

Axon

A

Neurons are carried away from the cell body by extensions of the neuron, called axon.

60
Q

Cell Body

A

Cell Body has a nucleus and organelles.

61
Q

Eye

A

It has four major parts, the Cornea, pupil, lens, and the Retina.

62
Q

Cornea

A

The front of the eye is covered by a clear membrane called the cornea.

63
Q

pupil

A

Light from an object passes through an opening called the pupil.

64
Q

Lens

A

Light hits those lens, an oval-shaped piece of clear, curved materials.

65
Q

Retina

A

It is a layer of light-sensitive photoreceptor cells that change light into electrical impulses.

66
Q

Touch

A

You feel a tap which then produces impulses and then travels to your brain. The brain then makes an awareness called sensation. The sensation could feel, temperature, pain, and so forth.

67
Q

Ear

A

The ear has three main parts, the outer ear, the middle ear and the inner ear.

68
Q

Outer ear

A

The outer ear receives is were the sound waves are entered.

69
Q

The middle ear

A

It lets the sound waves enter through. There , the sound waves make the eardrum vibrate.

70
Q

Inner ear

A

The last thing that sound waves have to go through are coclea.

71
Q

Cochlea

A

Is fluid-filled organ of the inner ear.

72
Q

Hair cells

A

These Sensory receptors move about in the fluid.

73
Q

Taste buds

A

These contain clusters of taste cells that respond to signals in dissolved molecules in food.

74
Q

Taste cells

A

Taste cells react to five basic tastes: sweet, sour, salty, bitter, and savory.

75
Q

Nose

A

Your nose is a sense for smell. Receptors for smell are located in the upper part of your nasal cavity.

76
Q

Sensory receptors

A

These Sensory receptors are called olfactory cells that react to chemicals in the air.

77
Q

Endocrine system

A

It helps controls body functions and contains homoeostasis by producing hormones.

78
Q

Hormone

A

It is a chemical messenger made in one cell or tissue that causes a change in another cell or tissue in a different part of the body.

79
Q

Gland

A

It is a group of cells that make special chemicals for your body.

80
Q

How are hormone levels controlled?

A

The endocrine system does this by increasing or decreasing the amount hormones in the bloodstream, some of which may have opposite effects on body cells. Such a process is called a feedback mechanism.

81
Q

Two types of feedback mechanisms

A

positive and negative

82
Q

Negative feedback mechanisms

A

In negative feedback, the effects of a hormone in the body cause the release of that hormone to be turned down. For example, when you eat food, your blood sugar levels go up. Insulin is released and blood sugar levels are lowered.

83
Q

Positive feedback

A

effects of a hormone stimulates release of more of that hormone. For example, the hormone oxytocin stimulates contractions of the uterus.
