respiratory related controls

CONTROLLER Brainstem(breathing boss)

Generates automatic rhythm&depth of breath

Tells you when to breath in and out

what two respiratory centers are part of the Central nervous system located in the Brainstem

Medulla oblongata and pons

What does the medulla control ?

involuntary breathing Breath in and out

What do pons control

Smooth and adjust breathing pattern

Cortex (Control)

Let’s you choose to control breathing

Chemoreceptors (Blood Detective)

Check blood for changes in pH,O2,CO2

Central chemoreceptor (medulla)

Respond to changes in CO2/pH

Peripheral chemoreceptors Plasma Police

Detect changes in O2, CO2, ph

What are the two bodies of peripheral chemoreceptors ?

Carotid(neck)

Aortic(Aorta)

Where does PCR send message to?

send message to the Brainstem

BREATH MORE

Boss controls chemistry phrenic

Brainstem- automatic breathing

Cortex-conscious control

Chemoreceptors-checks blood chemistry

Phrenic nerve- powers diagram

What is the primary function of Respiratory system

Gas exchange, giving oxygen and removing carbon

PUMP

Necessary air to move IN & OUT

What are the three respiratory muscles?

Diaphragm

Intercostal

Sterno&scalene

What does diaphragm do?

Creates negative pressure and contracts to allow more air

Intercostal muscles

expand and contract rib cage to allow more air

Stern and scalene muscle allow for

Extra breathing effort

MIXER is

A gas exhange between air and blood

Alveoli and lungs

CO2 is dropped off by capillary into alveoli and O2 is picked up by the capillary in the alveoli capillary carries CO2 back to lungs and is breathed out

VENTILLATION

ensure gas reaches alveolI

Air IN &OUT of lungs

What is the major muscle during VENTILLATION ?

Diaphragm: normal inspiration

what is an example of disease for ventilation?

COPD

Airflow limitation during expiration

DIFFUSION

Exchange of O2 and CO2 between alveoli and capillary

Disease of Diffusion

Pulmonary edema fluid interference with gas exchange

Respiratory

Bring O2 into body Gets rid of CO2

Blood-capillaries-alveoli

External

Exhange of gases between the lungs and blood

Internal

Exchange of gas between blood and body tissues

External exhange process

O2 - Alveoli - Blood

CO2- Blood -Alveoli

Internal

O2–blood—body cells

CO2- body cells - bl

Cellular respiration

cells turn into food (Glucose) into usable energy (ATP)

Glucose Comes Gets Pulled Makes ATP

Glucose

Cytoplasm

Glycolysis

Pyruvate

Mitochondria

ATP

Glucose turns to

Sugar

what enters in Cytoplasm

Glucose

Glycolysis splits into

1 glucose 2 pyruvate

What gets pulled during Glycolysis

Pyruvate enters if enough O2

ATP is created in the

Mitochondria

Aerobic

Air = ATP

GPO2ATP

Anaerobic

no Air

GPL

Call

All

People

CO2 turns into

Acid H2CO3

H+ INCREASES

pH Decreases

PaO2

Amount of pressure in arterial blood

SaO2

saturation of oxygen in arterial blood

SaO2 measures how many

Hb is inside RBCs

Henderson hasselbach

Find pH level of buffer solution

Tissue perfusion is

Blood delivery to cells and picking up CO2

Happy Ants Always Carry Very Large

Heart-

Arteries

Arteioles

Capillaries

Veins

Lungs

heart pumps

Oxygenated Blood out of left ventricles

Arteries Carry

Blood toward tissue

Arteioles control

How much blood enters each tissue

Capillaries exchange

Blood

Veins bring

Oxygenated blood back to the heart

Lungs

Drop off CO2 and pick up O2

CO=HRxSV

Cardiac Output

Heart Rate

Stroke Volume

Vasoconstrict

Vascular resistance

Squeezes - less Blood flow

Less O2 delivery to tissue

Vasodilate

Relaxed and widens

More blood

More O2

Styolic Squeezes

Heart is contracting

Mean Arterial Pressure

Average pressure in persons arteries during one single heartbeat

CO2 goes in or out of blood

Out Blood

ONW Capillary exchange

OBT Oxygen Blood Tissue

NBT Nutrients Blood Tissue

Waste CO2 Tissues Blood

Diastolic Down rest

Heart is relaxing

Tissue perfusion

Blood flows into body’s tissue receiving O2 and nutrients
