Anatomy 103 - 110

How are Cells and Tissues being bathed?

How are Cells and Tissues being bathed?

in plasma loaded with nutrients

Blood fluid =

plasma

Fluid around the cells =

matrix (interstitial fluid)

Fluid in the cell =

cytoplasm

Where does plasma leak from?

capillary

Where does plasma build up?

tissue

Cells take in __what____ to become ____what___?

• fresh new matrix

• new cytoplasm

Where does old cytoplasm leak into and why?

• matrix

• equal the pressure in the cell

What does old cytoplasm carry with it?

waste products

Examples of carried out waste products

creatine urea, ammonia, extra water, extra salt

What is filtered out of blood by?

kidney and liver

What’s the hero of the capillary vessels?

lymph vessels

Lymph vessels are/have

• permeable

• have small values helping them absorb extra matrix(fluid)

Where do lymph vessels absorb extra matrix?

post capillary area

Is the reabsorption of the fluid from the tissue into capillary efficient?

no

How much fluid is returned to the blood in one day? What returns it?

• 5 liters

• lymph vessels

What else do lymph cells absorb?

debris, bacteria

What has to happen before the fluid is returned to the blood?

cleaned, scanned through lymph nodes

Venules are what and allow what?

• small blood vessels

• deoxygenated blood to return from the capillary beds to the larger blood vessels

What are the larger blood vessels called?

veins

Veins are what and do what?

• large blood vessels that carry blood to the heart

Where do veins ALWAYS return the blood to?

the heart

Is there more arteries than veins or veins than arteries

more veins than arteries

what are the two types of veins

deep and superficial

Where are deep veins located at?

next a main artery

Whats deep veins relation to the artery and what do they do with it?

• “married”

• travel and takes artery’s name

deep veins job?

to return blood back to the heart

Superficial veins are like

Single ladies

What do superficial veins have to back up the body?

• name

• entire way?

Where are superficial veins located?

Under the skin

Superficial veins’ job and extra job?

• returning blood to the heart

• Help in thermoregulations

Thermoregulation

• When body heat increases/its hot veins come to the surface to release heat.

• When it’s cold veins move down into the muscle to prevent heat loss

What don’t veins and lymph vessels have?

Pump

The 1/4 tricks to help veins+lymph vessels return blood back to the heart?

Veins use valves to stair step blood back into the heart when traveling against gravity

Are valves in the vein or heart tougher?

Heart

Valves are what tissue?

Long thin connective tissue

The 2/4 tricks to help veins+lymph vessels return blood back to the heart?

• Muscle contractions,

• veins flow on top or within skeletal muscle

• when the muscle contracts it helps pushing the blood from one valve to the next

What is area between one valve and another called?

Compartment

The 3/4 tricks to help veins+lymph vessels return blood back to the heart?

• pulse of an artery

• Deep veins travel next to an artery

• Arteries are elastic and stretch on systolic push of heart, pushing on the veins when expanding

• This push helps blood move to the next valve compartment

The 4/4 tricks to help veins+lymph vessels return blood back to the heart?

• the movement of the diaphragm

• Inhalation + exhalation of the diaphragm pushes the vena & cava

• Pushing the vena & cava pushes blood back up to the heart, this movement uses the capillary pull to move blood out the legs and into the abdomen
