Q

What is the principal of complementarity of structure and function?

A

Q

What is the order of hierarchy structure for living tissue and the body?

A

Atoms tiny building blocks of matter and cells the smallest unit of living things
Atoms combine with proteins and water to create molecules
Molecules in turn arrange themselves in a specific way to form and become organelles
Organelles combine in like groups and form tissue

27
Q

What is epithelium?

A

A tissue that covers the bodies surface and lines it’s cavities.

28
Q

What is the purpose if muscle?

A

To provide movement in some instances to generate heat

29
Q

What does connective tissue do?

A

Connective tissue provides a means of rapid internal communication by transmitting electrical impulses

30
Q

What is an organ?

A

An organ is a discrete structure composed of at least two types of tissue however it is usually composed of all four. For example the stomach lining is epithelium that produces digestive juices the bulk of it is muscle that churns and mixes the stomach and the connective tissue reinforces the soft muscular walls and nerve fibres increase digestive activity by stimulating the muscle to contract.

31
Q

What is the highest level of organisation in the body?

A

The organism all level is the highest level of organisation in the body and represent the total of all structural levels working together to promote life.

32
Q

What is the multicellular state in relation to the body?

A

Is the parceling out of vital body functions to several different organ systems resulting in the interdependence of all body cells.organ systems do not work in isolation.

33
Q

Why is maintaining boundaries important within the body?

A

It is important to maintain boundaries so that the internal environment or insides remain distinct from the external environment outside.

34
Q

Explain boundaries in a single celled organism?

A

In single celled organisms the external boundary is a limiting membrane that encloses its contents and admits needed substances while restricting entry of potentially damaging or unnecessary substances

35
Q

What are all cells in the body surrounded by

A

A permeable membrane as a whole the body is enclosed and protected by the integumentary system or skin which protects the internal organs from drying out a fatal change, bacteria and the damaging effect of heat sunlight and chemicals

36
Q

What is contractility?

A

Contractility in relation to the muscles ability to move by shortening

37
Q

What is responsiveness or irritability in relation to the body

A

Responsiveness or irritability is the ability to sense changes (stimuli) in the environment and respond to them or temperature changes or a drop in ixygen levels

38
Q

What is digestion?

A

Digestion is the breaking down of ingested food stuffs to simple molecules that can be absorbed into the blood.the nutrient rich blood is then distributed to all body cells by the cardiovascular system

39
Q

What is described as a one celled organism that itself is a digestion factory?

A

A single celled organism such as amoeba

40
Q

The human body is multicellular true or false

A

True the multicellular human body performs the function for the entire body

41
Q

What is metabolism?

A

Metabolism is a “state of change” a broad term that includes all chemical reactions that occur within the body cells and includes the breaking down of substances into simpler building blocks ie catabolism

42
Q

What is catabolism?

A

The breaking down of substances into simpler building blocks.

43
Q

What is anabolism?

A

Anabolism is synthesising or creating more complex cellular structures from simpler substances

44
Q

What is cellular respiration?

A

Cellular respiration is using nutrients and oxygen to produce via ATP the energy rich molecules thy power cellular activities.

45
Q

What does the metabolism depend on?

A

The metabolism depends on the digestive and respiratory system to make nutrients and oxygen available to the blood and cardiovascular system

46
Q

What does the integumentary system of the body involve?

A

Hair, skin,nails protects deeper tissues from injury, synthesised vitamin dans is a site of cutaneous (pain, pressure vet) receptors and sweat oil glands

47
Q

What is the skeletal system and it’s function?

A

Protects and supports body organs and provides the framework for the muscles to pull on and create movement.blood cells are formed within bones as stored minerals

48
Q

What is the muscular system an it’s function?

A

The muscular system allows movement and manipulation of the environment, locomotion and facial expressions, maintaining posture and producing heat

49
Q

What is the nervous system?

A

The nervous system is fast acting control system of the body which responds to internal and external changes by activating appropriate muscles and glands.it involves the sensory receptor in the brain the spinal cord and nerves

50
Q

What is the endocrine system?

A

The endocrine system secretes hormones that regulate processes such as growth,reproduction and nutrient use (metabolism) by body cells

51
Q

What is the cardiovascular system?

A

The cardiovascular system involves blood vessels transporting blood oxygen,carbon dioxide, nutrients, wastes.the heart pumps the blood

52
Q

What is the lymphatic system/immunity?

A

The lymphatic system picks up fluid leaked from blood vessels and returns it to the blood.disposes of debris in the lymphatic stream: houses white blood cells (lymphocytes) involved in immunity.the immune response mounts the attack against foreign substances within the body.

53
Q

What does the lymphatic system involve?

A 
Lymphatic vessels
Thymus
Thoracic duct
Spleen
Lymph nodes
Red bone marrow
54
Q

What is involved in the respiratory system?

A

The respiratory system keeps blood constantly supplied with oxygen and removes carbon dioxide and gaseous exchanges occur through the walls of the air sacks of the lungs

55
Q

What are key components of the respiratory system?

A 
Nasal cavity
Pharynx
Larynx
Trachea
Lung
Bronchus
56
Q

What is involved within the digestive system?

A

The digestive system breaks down food into absorbable units that enter the blood for distribution to body cells.indigestible food stuff is eliminated as feces

57
Q

What are key components within the digestive system?

A 
Oral cavity
Esophagus
Liver
Stomach 
Small intestine 
Large intestine
Rectun
Anus
58
Q

What is the urinary system?

A

The urinary system eliminates nitrogenous wastes from the body, regulates water, electrolyte and acid balance of the blood.

59
Q

What are key components of the urinary system.

A

Kidney
Ureter
Urinary bladder
Urethra

60
Q

What is the function of the male an female reproductive system?

A

Overall function to produce offspring.testes produce sperm and male sex hormone, ducts and glands aid in the delivery of sperm to the female reproductive tract.ovaries produce eggs and female sex hormones and the remaining structures serve as sites for fertilisation and development if the fetus.mammary glands produce milk

61
Q

What key components are within the male reproductive system?

A 
Prostate gland
Testis
Scrotum
Ductus
Deferens
62
Q

What key components are involved within the female reproductive system?

A 
Mammary glands
Ovary
Uterus
Vagina
Uterine tube
63
Q

What is homeostasis?

A

A state of equilibrium or stable internal environment within the body

64
Q

What is excretion?

A

Excretion is the process of removing (excreta) or wastes from the body with the help of several organ systems. Ie digestive system rids of indigestible food residues as feces.the urinary system disposes of nitrogen containing metabolic waste such as urea in urine.carbon dioxide is the by product if cellular respiration where it is carried by the blood to the lungs and leaves the body as exhaled air
