Flashcards in Ch 1: Organ Systems Deck (24):
1

Anatomy vs Physiology

Anatomy: study of body structures and their relationships to one another
Physiology: study of function of body structures

2

Branches of Anatomy

Gross Anatomy: structures that can be seen with the naked eye
Embryology: development of the body's form
Microscopic: cytology and histology
[cell / tissues]

3

How many organ systems function together to maintain homeostasis

11 organ systems

4

11 organ systems

1. Integumentary
2. Skeletal
3. Muscular
4. Nervous
5. Endocrine
6. Cardiovascular
7. Lymphatic
8. Respiratory
9 Digestive
10. Urinary
11a. Male reproductive
11b. Female reproductive

5

Integumentary System

Provides protection, regulates body temp, prevents water loss
(site of cutaneous receptors, synthesis of V-D)

6

Skeletal System

Provides support, protection, homeopoiesis, stores calcium/phosphorus, site for muscle attachment

7

Muscular System

Provides body movement, generates heat when muscles are moved

8

Nervous System

Regulatory System
Controls body movement, responds to sensory stimuli
(responsible for consciousness, intelligence, memory)

9

Endocrine System

Consists of glands and cell clusters that secret hormones

10

Master Endocrine Gland

Pituitary Gland

11

Cardiovascular System

Cardio: heart
Vascular: vessels
everything to do with vessels that attach to the heart

12

Lymphatic System

Transports and filter lymph, initiates an immune response when necessary

13

What is lymph?

interstitial fluid transported through lymph vessels

14

What is interstitial fluid?

Main component of extracellular fluid

15

What is extracellular fluid?

All body fluid outside of the cells

16

Respiratory System?

Exchange of gases between blood and the air in the lungs

17

Digestive System?

Mechanical and chemical digestion of food materials, absorbs nutrients, and expels waste

18

Urinary System?

Filters the blood and removes waste products from the blood; expels waste products through urine

19

Male Reproductive System?

Produces male sex cells (sperm) and male hormones (testosterone), transfers sperm to the female [or the toilet, tissue, or sock]

20

Female Reproductive System?

Produces female sex cells (oocytes/eggs) and female hormones (estrogen and progesterone), receives sperm from male, site of fertilization of oocytes/eggs, site of growth and development of embryo and fetus

21

The Ductus Deferens are also known as?

The Vas Deferens

22

The Uterine Tubes are also known as?

The Fallopian Tubes

23

Male and Female Gonads?

Male: Testes
Female: Ovaries

24

Male and Female Gametes?

Male: Sperm
Female: Oocytes / Eggs
