Chapter 3 Flashcards
What are the 3 components of the Cardiovascular system
Heart, Blood, Blood vessels
What are the 4 components of the Respiratory system
Lungs, Alveoli, Bronchi, Trachea (bro lat)
What do the cardiovascular and cardiorespiratory systems work together to do
Deliver 02 to tissues of the body and remove waste form tissues of the body
What are the 3 functions of the heart
Stroke volume, Heart rate, Cardiac output
Total amt of blood pumped out of the heart with each contraction
SV
Rate at which the heart beats
Heart rate
Average adult heart rate
70-80 bpm
Volume of blood pumped by the heart per minute
Cardiac output
Cardiac output equation
HRxSV
Name the 3 functions of blood and explain each
- Transportation: transports 02 to tissues and waste products from tissues. Transports hormones to organs and tissues and carries heat throughout body
2 Regulation: regulates body temp and acid balance
- Protection: From excessive bleeding, disease, and sickness
What is the main function of the respiratory system
Bring 02 into the lungs and remove co2 from the lungs
Normal breathing uses what muscles?
Diaphram and external intercostal
Deep forced breathing uses what muscles
Pectoralis minor and the Scalenes
What are some instances where we see deep forced breathing
Stressful situations, physical, mental, or emotional stress.
What are two side effects of deep forced breathing
Headaches and anxiety
List the 5 types of blood vessels in the order the blood travels through the systemic circuit
Arteries, arterioles, capillaries, venules, veins
Name the conducting airways
nasal cavity oral cavity pharynx larynx Trachea Rt and Lt Pulm bronchi bronchioles
Name the respiratory airways
Alveoli
Alveolar sacs
best time and place to monitor heart rate
Radial(wrist) 3 mornings in a row
Inspiration muscles
Diagphram, external intercostals, pectoralis minor, sternocloidmastoid, scalenes
Expiration muscles
Abs, Internal intercostals
Study of energy in the human body
Bioenergtics
Chemical reactions that occur in the body to maintain itself, process in which nutrients are acquired, transported, used, and dispersed by the body.
Metabolism
Bioenergetics as it relates to pysiologic changes and demands placed upon the body during exercise
exercise metabolism
Material or substance in which an enzyme acts
Substrates
Carbon, hydrogen, o2 . cellulose, starches and sugar broke into glucose.
Carbs
Simple sugar manufactured by the body from carbs, fats, and to a lesser extent protein. Bodys main source of fuel
Glucose
Complex carb molecule used to store carbs in liver and muscle cells.
Glycogen
One of the three main classes of food. triglycerides, phosolipids and sterols
fats
Chemical or substance form in which most fat exists in food as well as the body
Triglycerides
Amino acids linked by peptide bonds which consist of hydrogen, nitrogen, o2, sulfer
Protein
A system of organs that collect oxygen from the external enviroment and transport it to the blood stream
Respiratory system
Composed of skeletal structires and soft tissues taht work together to allow proper respiratory mechanics to occur and help blood pump back to heart during inspiration
Respiratory Pump
Process of actively contracting the inspiratory muscles to move air into the body
Inspiration
Process of actively or passively relaxing the inspiratorymuscles to move air out of the body
Expiration
