1
New cards
Blood
A liquid that contains plasma, and cellular and formed elements such as erythrocytes (RBC), leukocytes (WBC), and thrombocytes (platelets).
2
New cards
Erythrocytes (RBC)
Mature red blood cells that do not have a nucleus, live for about 90-120 days, transport oxygen, carbon dioxide, and nitric oxide.
3
New cards
Leukocytes (WBC)
White blood cells that are categorized into two groups: granular (e.g., neutrophils, basophils, eosinophils) and agranular (e.g., monocytes, lymphocytes).
4
New cards
Neutrophils
Granular WBCs that serve as the first line of defense in the body, are phagocytic, and have a lilac-stained appearance.
5
New cards
Erythropoiesis
The process of RBC production stimulated by the hormone erythropoietin produced by the kidneys.
6
New cards
Thrombopoietin (TPO)
A hormone produced by the liver that stimulates the formation of platelets.
7
New cards
Closed circulatory system
A system in which blood circulates within blood vessels, found in humans and other vertebrates.
8
New cards
Open circulatory system
A system where blood mixes with interstitial fluid and is pumped into a body cavity, found in arthropods and mollusks, with the mixture called hemolymph.
9
New cards
Atria
The upper chambers of the heart that receive blood.
10
New cards
Ventricles
The lower chambers of the heart that pump blood out of the heart.
11
New cards
Systole
The contraction phase of the cardiac cycle when the heart pumps blood.
12
New cards
Diastole
The relaxation phase of the cardiac cycle when the heart fills with blood.
13
New cards
Capillary beds
Networks of capillaries that are the sites of chemical exchange between the blood and interstitial fluid.
14
New cards
Cardiac output
The volume of blood pumped by the heart per minute, dependent on heart rate and stroke volume.
15
New cards
SA Node
The pacemaker of the heart located in the chest that generates electrical signals to initiate heart contractions.
16
New cards
Blood pressure
The force exerted by circulating blood on the walls of blood vessels, measured in millimeters of mercury.
17
New cards
Anemia
A condition caused by inadequate red blood cell production.
18
New cards
Leukemia
A cancer caused by genetic changes that affect blood cells produced in the bone marrow.
19
New cards
Phagocytes
A type of white blood cell that engulfs and destroys bacteria and debris through a process called phagocytosis.
20
New cards
Thrombus
A blood clot that can block blood flow, potentially leading to serious health issues.
