1
The Human Body Systems
2
Circulatory System Transport materials to and from cells
3
Circulatory System Organs
Heart Veins Arteries Capillaries Red blood cells
4
Respiratory System Takes in oxygen and removes carbon dioxide and water
5
Respiratory System Organs
Nose Trachea Bronchi Bronchioles Alveoli Lungs
6
Digestive System Take in food (ingestion)
Digest food into smaller molecules and absorb nutrients Remove indigestible food from body (feces)
7
Digestive System Organs
Mouth, Rectum, Anus Esophagus Salivary glands Stomach Small Intestine Pancreas, Liver Large intestine Gall bladder
8
Endocrine System Regulates body activities using hormones. Slow response, long lasting
9
Endocrine System Organs
Glands Hypothalamus Pituitary Thyroid Thymus Adrenal Pancreas Ovaries Testes Glands produce Hormones
10
Nervous System Gathers and interprets information
Responds to information Helps maintain homeostasis
11
Nervous System Organs Brain Spinal cord Nerves Nerve cells = neurons
Hypothalamus
12
Muscular System Allows for movement by contracting
13
Muscular System Organs
Cardiac muscle Smooth muscle Skeletal muscle Tendons
14
Skeletal System Protects organs Provides shape, support
Stores materials (fats, minerals) Produces blood cells Allows movement
15
Skeletal System Organs
Bones Cartilage Ligaments
16
Excretory System Removes waste products from
cellular metabolism (urea, water, CO2) Filters blood
17
Excretory System Organs
Kidneys Ureters Bladder Urethra Lungs Skin – sweat glands Liver (produces urea)
18
Integumentary System Barrier against infection (1st line of defense)
Helps regulate body temp. Removes excretory waste (urea, water) Protects against sun’s UV rays Produces vitamin D
19
Integumentary System Organs
SKIN Epidermis Dermis Sweat gland Sebaceous gland (oil) Hair follicle Blood Vessels Nerves
20
Immune System Fights off foreign invaders in the body
21
Immune System Organs White Blood Cells Macrophages Skin T cells
B cells Produce antibodies Macrophages Skin
22
Lymphatic System Stores and carries WBC’s that fight disease
Collects excess fluid and returns it to blood (2nd circulatory system- Reaches places other one can’t; between cells)
23
Lymphatic System Organs
Lymph (liquid part of blood - plasma, when it’s in lymph vessels) Lymph Vessels Lymph Nodes Contain WBCs
24
Reproductive System Allows organisms to reproduce which prevents their species from becoming extinct.
25
Reproductive System Organs
Ovaries Produce eggs Testes Produce Sperm
26
System Interactions
27
Circulatory System Interactions
w/respiratory – deliver O2 from lungs to cells and drop off CO2 from cells to lungs w/digestive – absorb and deliver digested nutrients to cells w/excretory – kidneys filter cellular waste out of blood for removal w/lymphatic – both transport things to and from cells w/immune – transports WBCs throughout body to fight disease w/nervous – brain controls heartbeat w/endocrine – trans. hormones
28
Respiratory System Interactions
w/circulatory – takes in O2 for delivery to cells and removes CO2 brought from cells w/excretory – removes excretory waste w/nervous – controls breathing w/muscular – diaphragm controls breathing
29
Digestive System Interactions
w/circulatory – absorb & deliver the digested nutrients to the cells w/muscular – control the contractions of many of the digestive organs to pass food along w/nervous – hypothalamus maintains homeostasis by triggering appetite (stomach growling), digest.
30
Endocrine System Interactions
w/circulatory –transports hormones to target organs w/nervous – maintain homeostasis, hormone release w/reproductive – controlled by hormones w/skeletal – controls growth of bones
31
Nervous System Interactions
Controls all other systems Hypothalamus – maintains homeostasis by working with all systems
32
Muscular System Interactions
w/skeletal – allow movement w/digestive – allow organs to contract to push food through w/respiratory – diaphragm controls breathing w/circulatory – controls pumping of blood (heart) w/nervous – controls all muscle contractions
33
Skeletal System Interactions
w/muscular – allow movement w/circulatory – produce blood cells w/immune – produce white blood cells w/circulatory and respiratory – protects it’s organs
34
Excretory System Interactions
w/circulatory – filters waste out of blood w/lungs – removes excretory waste w/integumentary – removes excretory waste
35
Integumentary System Interactions
w/excretory – removes cellular waste w/nervous – controls body temperature (sweating, goose bumps) w/immune – prevents pathogens from entering
36
Immune System Interactions
w/circulatory – transports WBCs to fight invaders w/lymphatic – has lots of WBCs to fight invaders, spleen filters bacteria/viruses out of blood w/skeletal – WBCs made in bone marrow w/integumentary – prevents invaders from getting in
37
Lymphatic System Interactions
w/immune – holds lots of WBCs to fight pathogens w/circulatory – to transport materials to and from cells
38
Reproductive System Interactions
1. w/endocrine – controls production of sex cells 2. w/muscular – uterus contracts to give birth – controlled by hormones
