Exam 2- Cardiovascular System Flashcards
(46 cards)
Describe what a hematocrit is measuring
measurement of the proportion of red blood cells (RBCs) in a person’s blood
Plasma ( Top layer)
55% of blood volume (fluid watery). Contains ion, nutrients, waste and protein. Three main protein, albumin, fibrinogen, globulin

Buffy Coat
( leukocyte and platelets)
red blood cell
Erythrocytes
thrombocytes
Platelets
white blood cell
Leukocytes
BLANK lose their nucleus and most organelles during maturation, so they aren’t considered ‘’complete’’ cells.
RBC
are fragments of megakaryocytes and lack a nucleus, making them cell fragments rather than actual cells
Platelets
retain their nuclei and are fully functionally cells
WBC
transport oxygen from lungs to tissues and carbon dioxide from tissue to lungs
Function of RBC
Life expectancy
120 days life expectancy
(Formation) amino acids and iron recycled; produced in BLANK BLANK
bone marrow
(Removal) Old RBC are removed by macrophages in the BLANK, BLANK and BLANK, where they are broken down, and their components are recycled
spleen, liver and bone marrow
plasma proteins
Albumins, Fibrinogen, Globulin
-most abundant
- Maintain osmotic pressure, transport substances, and buffer blood pH
Albumins
-is an essential clotting factor
- is converted by the enzyme thrombin into fibrin, which forms the mesh-like framework of a blood clot.
Fibrinogen
Serve as transport proteins, contribute to immune function (gamma globulins or antibodies), and assist in clotting.
Globulin

Neutrophils
Lymphocyte
Monocyte
Eosinophils
Basophils
Granulocytes
Neutrophils(most common)
Eosinophils
Basophils
Agranulocyte
Lymphocyte
Monocyte
BLANK have lobed nuclei; agranulocytes have larger, often unlobed nuclei.
Granulocytes
BLANL are more involved in immediate immune responses, while BLANKre crucial for adaptive immunity and long-term defense mechanisms.
Granulocytes, agranulocytes
