^ high altitude means _____ Oxygen
- answer-Decrease
Hematocrit ^ RBC's, which ^ oxygen
3 Structural components of the cardiovascular system
- answer-1. Connective tissue
2. Smooth muscle
3. Endothelium
Actin
- answer-The protein "track" on which myosin motors move
Forms a cross-bridge when it binds to actin
Thin filaments
Active inhaliation
- answer-Air in, muscles contract
Air within Alveoli in the lungs has...
- answer-Less O2 and more CO2 than air in the atmosphere
Alveoli
- answer-Function units of the lungs, gas exchange of oxygen and carbon dioxide
- Where respiratory system meets CV system
- Filled with air
- Exchange between air and blood by diffusion
Anemia
- answer-Low Hb or hematocrit
Angiogenesis
- answer-Growth of new blood vessels
,Antibodies
- answer-Protein components of the immune system
Produced by WBCs
Anticoagulant
- answer-Heparin
Arteries
- answer-Major blood vessels
AV Node
- answer-Region of specialized cells between the atria and ventricles
Aveolar
- answer-- Fundamental function unit of lungs
- O2 from atmosphere is transferred to the blood
Bicarbonate
- answer-An ion with one negative charge, information indicated by a
superscripted "-" in the chemical formula
Transport form of CO2
Serves as a second role in homeostasis as a pH buffer (a molecule that minimizes
changes in pH despite production or use of proteins)
Biceps/Triceps contraction and relaxation example:
- answer-Pair of antagonistic muscles
When bicep contracts, tricep is relaxed
CONVERSELY
When tricep contracts bicep is relaxed
Muscles only shorten when they contract actively
When antagonist muscle contracts, it re-lenghens the other, relaxed muscle
Active = short
Relaxed = long
Biological catalysts
- answer-Speed up chemical reactions
Blood vessel cycle:
- answer-Vasculature > arteries > arterioles > capillaries > venules > veins > heart
> arteries....
, Botulinum toxin
- answer-- Botulism (food poisoning)
- Muscles are relaxed and flaccid because they can't be activated
Ca2+ transient
- answer-Temporary increase in Ca2+
Increased Ca2+ concentration activates cross-bridge cycling
Cancer spreading through metastasis...what does this look like?
- answer-A cancer cell leaves the blood, invades another tissue and begins forming
a new tumor, then the cancer has spread through metastasis
Carbon Dioxide
- answer-Gas that dissolves in plasma
Generated by our cells and then it must be removed
Carbonic anhydrase
- answer-Essential for CO2 transport
Catalyst
Carbonic anhydrase (enzyme in RBC's) converts carbonic acid (H2CO3) back to
CO2 in the lungs
- answer-Carbonic acid (H2CO3) back to CO2 in the lungs
Cardiac and skeletal muscle have _____________
- answer-Striations
Cardiac and smooth are activated _____________
- answer-Involuntary
Cardiac cycle: Electrical
- answer-In one path, an action potential in one cell travels to adjacent cells by
direct electrical connections (gap junctions)
The other path allows for faster spread of the electrical signal from one part of the
heart to another
Cardiac muscle
- answer-Heart
