Q

WHAT IS PATHOPHYSIOLOGY?

A

Pathophysiology is the study of alterations to normal function that result from a disease or disorder.
This altered condition may arise from an abnormal process within the body, or it may be the body’s response to a foreign substance that has entered the body.

lateral means away from the midline, or towards the side.

23
Q

PROXIMAL

A

Proximal means towards the point of attachment to the body trunk

24
Q

DISTAL

A

distal means further from the point of attachment.

25
Q

SUPERFICIAL

A

Superficial means towards the body skin or surface

26
Q

DEEP

A

deep means towards the body centre or core.

27
Q

CENTRAL

A

Central means towards the body core, usually the head and trunk

28
Q

PRIPHERAL

A

peripheral means towards the body periphery or extremities

29
Q

DORSAL CAVITY

A

The dorsal cavity is in the dorsal (back) part of the body and contains the central nervous system.

30
Q

VENTRAL CAVITY

A

The ventral cavity is on the ventral (front) side of the trunk and contains most of the internal organs of the trunk.

31
Q

WHAT IS THE NERVOUS SYSTEM?

A

The nervous system consists of the brain, spinal cord and neurons, which sense variables throughout the body and stimulate the muscles to contract.

32
Q

WHAT IS THE ENDOCRINE SYSTEM?

A

The endocrine system consists of the organs, glands and cells that secrete hormones to regulate the anatomy and physiology of particular targets;

33
Q

WHAT IS THE IMMUNE SYSTEM?

A

The immune system consists of a range of cell types and tissues that protects and defends the body from destruction by foreign particles including bacteria, viruses and cancer cells.

34
Q

WHAT IS THE INGUMENTARY SYSTEM?

A

The integumentary system comprises the skin and mucous membranes (in areas without skin) that form the external covering of the body.

35
Q

WHAT IS THE HAEMATOLOGICAL SYSTEM?

A

The haematological system comprises the blood and bone marrow that form the blood components. The general functions of the blood are the transport of nutrients and wastes, and protection

36
Q

WHAT IS THE MUSCULAR SYSTEM?

A

The musculoskeletal system (muscles and bones) allows the body to move, as well as providing physical support for the internal organs. The functions of this system are far more critical than just allowing us to move

37
Q

WHAT IS THE CARDIOVASCULAR SYSTEM?

A

he cardiovascular system consists of the heart and blood vessels, which provide the means for the blood to travel to every body cell.

38
Q

WHAT I STHE RESPIRATORY SYSTEM?

A

The respiratory system (respiratory tract and lungs) exchanges oxygen and carbon dioxide with the environment, as well as enabling the production of speech.

39
Q

WHAT I STHE DIGESTIVE SYSTEM?

A

The digestive system includes the mouth, oesophagus, stomach, intestines, liver, gallbladder and pancreas.

40
Q

WHAT I STHE URINARY SYSTEM?

A

In the urinary system , fluid, electrolyte and acid–base balance is performed by the kidneys, with excess fluid and a range of wastes exiting the body in the urine.

41
Q

WHAT IS THE REPRODUCTIVE SYSTEM?

A

The reproductive system consists of glands and organs that allow for the production of offspring.

42
Q

HYDROPHILIC

A

Water loving

43
Q

HYDROPHOBIC

A

Water hating

44
Q

ALKALOSIS

A

PH level to high

Q

Normal PH range?

A

7.35 - 7.45

47
Q

WHAT ARE THE MOLECULES OF LIFE?

A

proteins, lipids and carbohydrates

48
Q

WHAT ARE PROTEINS?

A

A protein is a large molecule consisting of many amino acids linked together.

49
Q

WHAT ARE LIPIDS?

A

Lipids consist of fats (solid at room temperature) and oils (liquid at room temperature) comprised of the molecule glycerol, with some fatty acids linked to it.

50
Q

WHAT ARE CARBOHYDRATES?

A

Carbohydrates are your body’s main source of energy: They help fuel your brain, kidneys, heart muscles, and central nervous system.
