Cardiovascular system

Structures (3)

System type

Heart, blood vessels, blood

Closed system

1

Cardiovascular system

Types of vessels

Arteries - away from heart

Veins - converge toward heart

Capillaries - exchange, tiny vessels with thin walls

2

Cardiovascular system

Functions (3)

Transportation
Regulation
Defense

3

Cardiovascular system

Transportation

Blood carries oxygen, nutrients and chemical messengers to all cells (arteries)

Blood carries carbon dioxide and wastes away from cells (veins)

4

Cardiovascular system

Regulation

Blood helps the body regulate

Temperature
Water
Acid-base balance (Ph)

5

Cardiovascular system

Defense

Blood components help defend against disease and mend damaged blood vessels

- white blood cells defend us against disease and invading pathogens

- clotting: blood clotting cells mend damaged blood cells

6

Lymphatic systems

Structures (4)

System type

Lymph
Lymphatic vessels
Lymphatic organs
Lymphatic tissues


System type: open, 1 way system from tissues to blood

7

Lymphatic system

Functions (3)

Immunity - specific resistance to disease

Fluid balance - returns proteins and fluids to blood

Transportation - carries lipids from GI (gastrointestinal) tract to the blood

8

Skeletal system

Structure (3)

Bones, cartilage, joints

9

Skeletal systems

Functions (4)

Supports posture
Protects organs
Participates in movement/locomotion
Storage of fats, minerals and cells that produce blood cells

10

Bones description

Bones are our basic framework

Where bones touch there are joints

Cartilage reduces friction at the joints

11

Anterior

Toward the front

12

Posterior

Towards the back

13

Intermediate

In between two structures

14

Superficial

Toward the surface

15

Deep

Toward the inside (away from the surface)

16

Lower limb

Lower extremity or LE in notes

Thigh, knee, leg, ankle, foot, toes

17

Upper limb

Upper extremity or UE in notes

Arm
Elbow
Forearm
Wrist
Hand
Fingers

18

Muscle action

Origin

Origin or head of the muscle is the beginning of the muscle

The origin of a muscle is the proximal or inferior attachment and is usually fixed/stable.

19

Muscle action

Insertion

Insertion or end of muscle

The insertion of a muscle is the distal or superior attachment and moves toward the origin during contraction

20

Muscle action


Belly

The portion of muscle between the attachments

Contractile portion of the muscle

21

Muscle action

Action of the muscle

The movement that occurs when the belly pulls the insertion toward the origin.
