Flashcards in A&P 3.1 fluid network & cardiovascular system Deck (22):
0

Adductor longus

A, I, O

Proximal attachment: body of pubis, just below crest

Distal attachment: linea aspera of femur

Action: adduction of hip, assists flexion of hip

1

Rectus abdominus

A, I, O

Superior attachment: xipoid process of sternum, costal cartilage ribs 5-7

Inferior attachments: pubic crest, pubic symphysis

Action: flexion of trunk (spine), posterior tilt of pelvis

2

Pubis landmarks

Inferior and superior rami
Crest of pubis
Body of pubis

3

Rectus sheath

Made of aponeurosis of the other abdominal muscles

4

Three communication networks

Fascial - mechanical information

Neural - coded electrical information

Fluid - chemical information passed by means of all fluids

5

Lymphatic system

General

Provides an open pathway for the return of fluids and proteins from interstitial spaces and fats absorbed by from the intestine to general circulation

Also involved in immunity and resistance to disease and removal and destruction of dead RBC'S

6

Plasma

The fluid portion of the blood

7

Interstitial or extracellular fluid

Located in microscopic spaces between cells

8

Intracellular or cytosol fluid

Watery fluid inside cells

9

Blood

Parts

BREAK DOWN CARD

Liquid Connective tissue that consists of fluid and cells

Red blood cells - RBC - erythrocytes

White blood cells - WBC - leukocytes

Platelets - thrombocytes

Fluid - plasma

10

WBC produced by

Stem cells - many types

Bone marrow produces all three types

11

Functions of blood

Transportation

Homeostasis

Protection

12

Transportation

Vital pickup and delivery service for the body

13

Homeostasis

Regulatory functions keystone of the body's heat regulating mechanism

14

Protection

Blood clots which protects against excessive blood loss.

WBC's protect against disease by carrying on phagocytosis along with several anti-bodies

15

Functions of blood

Interacts with all cells and all of our systems
Main transport fluid - nutrient/waste exchange
Chemical messengers travel in blood to get to target cells
Picks up hormones and drop off at target
Picks up oxygen - drops off carbon dioxide
Picks up nutrients from digestive system
Picks up dietary fats from lymphatic system
Drops off liquid waste to kidneys, nutrients and oxygen to cells

16

Lymphatic system


Structures

Lymph nodes
Lymph vessels
Lymph fluid
Other lymphatic structures

17

Lymphatic system

Maintains fluid balance in the internal environment of the body and protects the body through the process of immunity

Lymphatic vessels act as "drains" to collect excess tissue fluid and return it to the venous blood just before it reaches the heart

18

Lymph

Described

Clear watery-appearing fluid found in lymphatic vessels

19

Fluid flow

Sequence of fluid flow:

Plasma in capillaries to
Interstitial spaces as interstitial fluid to
Lymphatic capillaries as lymph to
Lymphatic vessels as lymph to
Lymphatic ducts as lymph to
Subclavian vein as plasma

20

Cardiovascular system

Parts

3 parts

Heart - muscular pumping device
Blood
Vessels - arteries, veins, and capillaries

21

Cardiovascular system function

To maintain homeostasis, which depends on the continuous and controlled movement of blood through the thousands of miles of capillaries that permeate every tissue and reach every cell in the body
