Circulatory Physiology Flashcards
3 functions of the circulatory system
- Transportation
- Regulation
- Protection
White blood cells
- Neutrophils
- Lymphocytes (T cells - release cytokines and attack abnormal cells and B cells - release antibodies
- Macrophages
- Eosinophils - parasites and allergic response
- Basophils - release histamine for inflammatory response and help in parasitic response
Substances are essential for cellular metabolism are transported. These substances can be categorized as follows…
- Respiratory
- Nutritive
- Excretory
Another name for RBCs
Erythrocytes
Higher ambient temperature = diversion of blood from _________ vessels helps cool the body
Lower ambient temperature = diversion of blood from _____________ vessels helps keep the body warm
deep to superficial
superficial to deep
Mechanism protects against loss of blood when vessels are damaged
Clotting
Disease-causing agents
Pathogens
The circulatory system is made up of the:
Blood vessels
Heart
Blood
This i the blood plasma
Lymph
Lymph properties
Unable to get back directly into the blood capillaries
Directly bathed the cells of tissues and carrots digested foods and oxygen
Cells loose to their lymph their waste substances, urea, and carbon dioxide
How many percent in the body weight is fluid
60%
How many percent is body fluid inside the cell
40%
How many percent is body fluid outside the cell
20%
Type of circulatory system that pumps blood into a hemocoel with the blood diffusing back to the circulatory system between cells
Open circulatory system
Which animals are open circulatory system most common
Molluscs and arthropods
