Q

Describe the 3 internal organ function of the muscular system

A

Smooth muscle produces rythmic contractions that propel food through GI tract

Smooth muscle in bladder wall allow urine to be expelled

Smooth muscle in uterine lining allows for vaginal deliveries

21
Q

Describe the 2 circulating blood functions of the muscular system

A

Cardiac muscle contracts the heart and sends blood through body

Smooth muscle in the walls of blood vessels alter the diameter of these vessels depending on the situation (constrict if less blood is needed)

22
Q

DESCRIBE THE BODY TEMPERATURE FUNCTION OF THE MUSCULAR SYSTEM

A

When body temp is low, smooth muscle constrict to conserve heat

When body temp high, smooth muscle relaxes, increasing blood flow and heat release through skin

23
Q

What are the 3 functions of the nervous system

A

Sensory input

Integration

Motor response

24
Q

Describe the sensory function of the nervous system

A

Sensory receptors monitor change and gather info

25
Q

Describe integration function of the nervous of the. Nervous system

A

CSN processes and interprets this information and determines the action to be taken

26
Q

Describe motor response function of the nervous system

A

Activates effector organs to cause a response

27
Q

5 Components of the cardiovascular system

A 
Heart 
Arteries 
Veins 
Capillaries
Blood
28
Q

Describe the % breakdown of blood and the 3 contents

A

45% blood 55% plasma

Red blood cells, white, and platelets

29
Q

Describe the single function of the CV system and what that function accomplishes

A

The function is transportation

Works with respiratory system to deliver oxygen rich blood to body

Removes co2 from cells, delivers nutrients, removes metabolic waste

Serves as highway for white blood cells to search body for germs

Transportation of hormones from endocrine glands to organs

30
Q

2 sections of respiratory tract

A

Upper and lower respiratory tract

31
Q

What 4 organs are in the upper respiratory tract

A

Nose, mouth, pharynx, larynx

32
Q

What 4 organs are in the lower respiratory tract

A

Trachea, bronchi, alveoli and lungs

33
Q

Function of the respiratory tract

A

To absorb oxygen from the air into the blood, and discharge the co2 out of the body

34
Q

Another name for digestive tract

A

Gastrointestinal of GI tract

35
Q

Major accessory organs of the digestive system

A

Gall bladder and the pancreas

36
Q

3 Functions of the digestive tract and explain

A

Digestion

absorption

Eliminates unused material as waste

37
Q

What 4 organs is the excretory/urinary system composed of?

A

Kidneys, ureters, urinary bladder, urethra

38
Q

4 Functions of the urinary system

A

Maintains the volume and comp of body fluids within normal limits

Helps regulate blood pressure

Acts as a filter and rids the body of waste products through the urine

Regulates pH of the blood

39
Q

3 Functions of the reproductive systems

A

Ensures survival of species

Produces eggs, sperm and horomones

Nurtures developing offspring

40
Q

What are the 4 primary reproductive organs

A

Ovaries, testes, uterus, penis

42
Q

Lymphatic system function to do what 4 things

A

Helps get rid of body toxins and waste

Transport lymph (containing white blood cells) around the body

Returns excess interstitial fluid to blood

Absorption of fats and vitamins from digestive system

43
Q

The integumentary system is ____________ and consists of what 4 things?

A

Largest organ of the body and consists of skin, hair, nails and exocrine glands

44
Q

3 Function of the integumentary system

A

Acts a barrier to protect body from external damage

First line of defence against bacteria, viruses and other microbes

Assists in maintaining homeostasis by regulating body temperature and water balance

45
Q

What are the 9 Endocrine system organs

A

Pituitary, pineal, thyroid, parathyroid and adrenal glands

Hypothalamus, pancreas, ovaries and testicles

46
Q

Function of endocrine system

A

Functions in the regulation of body activities through chemical messengers known as horomones

47
Q

2 categories of glands in the body

A

Exocrine and endocrine glands

48
Q

What are exocrine glands, what system are they in and what are 5 examples?

A

Part of integumentary system

Glands that produce and secrete substances onto an epithelial surface or into lumen by the way of a duct

Sweat, salivary, mammary, lacrimal,mucous

49
Q

What are endocrine glands, what system are they in and 9 examples

A

Part of endocrine system

Secrete their products (horomones) directly into the blood rather than through a duct

Pineal, adrenal, pancreas, ovaries, testes, thyroid, parathyroid, hypothalamus, pituitary
