ventricular repolarization

What is the heart doing during the measure of systolic pressure and diastolic pressure?

systolic= pumping/emptying

diastolic= relaxing/refilling

When someone smokes is reduces the surface area in their __________.

Alveolar Sacs

What is the primary function of the excretory System?

the removal of metabolic wastes from the blood and eventually from the body.

When an oocyte is released from an ovary, it will travel into the _________ where fertilization takes place.

oviduct

What hormone is found in the kidneys?

antidiuretic hormone

what do the hormones oxytocin and prolactin do?

stimulate the creation and secretion of milk

What major areas can the brain be divided into?

The cerebral hemispheres, the diencephalon, the brain stem, and the cerebellum

What are the lobes of the brain and their function?

1) Frontal Lobe: control panel for personality and the ability to communicate

2) Temporal Lobe: hearing, auditory, and memory

3) Parietal Lobe: Reading(?) and senses and pain

4) Occipital Lobe: Visual

What is the diencephalon made up of?

the epithalamus, thalamus, and hypothalamus

What are the parts of the brain stem?

the midbrain, pons, and medula oblongata

What is the function of the Cerebellum?

coordinates muscle activity

What are the functions of the hypothalamus?

regulation of body temp, water, and sensory feelings such as pain and thirst

blood flow of heart

carry blood away from the heart

aterioles(arteries)

carry blood to the heart

veins

represents depolorizatioin. Both Atria Contract

"P" wave

The Respiratory system

Respiratory system

smokers lungs have carbon

lung tissue

alveoli

are thin walled structures that are well-suited to facilitate the diffusion of oxygen and carbon dioxide across their membranes and to-or-from the blood capillaries that cover them.

.

The volume of air that is inhaled and exhaled at rest.

Tidal Volume

The volume of air that can be inhaled after taking a normal (tidal) inhalation.

Inspiratory Reserve Volume

The volume of air that can be exhaled after making a normal (tidal) exhalation.

Expiratory Reserve Volume

The volume of air that represents the largest inhalation you can take followed by the deepest exhalation you can make.

Vital Capacity

The volume of air you cannot exhale. It remains in the lungs to keep the alveoli partially inflated.

Residual Volume

The maximum volume of air the lungs can hold. This is the sum of your vital capacity and the residual volume.

Total Lung Capacity

The primary function of the Excretory System is the removal of metabolic wastes from the blood and, eventually, from the body.

in lab how were you measuring enzyme activity. (How could you tell if the reaction had occurred and broken down the substrate?)

a change in color determined if benzoquinone was produced.

brown- high enzyme activity

light brown- less enzyme activity

clear-low/no enzyme activity

In the reaction with catechol oxidase, identify the substrate, enzyme, and product.

substrates- catechol and oxygen

enzyme- catechol oxidase

product- benzoquinone and water

When you used the beans in your respiration experiment, what were you measuring and how did that Value change over time?

measuring amount of CO2; increases as time increases

What affect does respiration have on temperature?

during respiration, heat is produced.

How did you measure your production of carbon dioxide in lab?

add bromothymol blue to two test tubes. Its color changes in the presense of CO2:
